Compassion is considered the cornerstone of nursing practice. However, the recent failures in delivering high-quality compassionate nursing care in the UKs National Health Service have brought the topic of compassion to the attention of the public, service providers, policy makers and academics.The aim of this study was to explore the nurses views and experiences of a number of compassion-related issues in nursing and describe similarities and differences at an international level as well as from the different nursing roles of the participating nurses.An exploratory, cross-sectional descriptive study, using the International Online Compassion Questionnaire. A total of 1323 nurses from 15 countries completed the questionnaire.The majority of participants (59.5%) defined compassion as Deep awareness of the suffering of others and wish to alleviate it but definitions of compassion varied by country. Of participants, 69.6% thought compassion was very important in nursing and more than half (59.6%) of them argued that compassion could be taught. However, only 26.8% reported that the correct amount and level of teaching is provided. The majority of the participants (82.6%) stated that their patients prefer knowledgeable nurses with good interpersonal skills. Only 4.3% noted that they are receiving compassion from their managers. A significant relationship was found between nurses experiences of compassion and their views about teaching of compassion.Our study is unique in identifying the views and experiences of nurses from 15 different countries worldwide. The findings reveal that compassion is neither addressed adequately in nursing education nor supported in the practice environment by managers.Self-report bias was inherent to our survey study design. Furthermore, the individual cultural differences and similarities in the findings are difficult to extrapolate owing to the fact that our analysis was at country level, as well as at the level of the participating nurses.Understanding the influence of culture on nurses views about compassion is critical in the current multicultural healthcare environment and merits further research. This will potentially drive changes in nursing education (ensuring that compassion is taught to nurses) and in the way healthcare leaders and managers foster a compassionate culture within their organizations (e.g. by leading by example and compassionate to their staff).

Three estuarine-linked streams (Bulusan, Iyam, and Pansipit rivers) in different protected areas were investigated to evaluate the influence of environmental and habitat variables on gobioid assemblages (Gobiidae and Eleotridae). The study collected a total of 1,071 specimens belonging to 19 species, and 17 genera. Twelve gobiids and seven eleotrids were recorded from the three rivers. Four gobioid species comprised 57.17% of the total abundance. These were Giuris margaritacea (Eleotridae), Glossogobius celebius (Gobiidae) Bostrychus sinensis (Eleotridae) and G. giuris (Gobiidae) (in order of importance). Log10-transformed abundance data were used in indirect (detrended correspondence analysis, DCA), and direct (canonical correspondence analysis, CCA) gradient ordination analysis. DCA (50.76% variability on the first and second ordination axes) revealed the gobioid assemblage variability as a response of species abundance to stream gradients. Species variation along the longitudinal stream gradient profile (upstream and downstream dwellers) was also emphasised. From the 19 environmental variables, CCA (71.49% variability on the first and second ordination axes) recognised substratum types, distance to sea, and land use pattern as the most weighted causative environmental parameters influencing the gobioid assemblages (within and between stream variations). Bray-Curtis similarity analysis using species and abundance data registered low similarity percentages (18–40%) between the three rivers, validating the high beta diversity estimated in DCA1 axis. © National University of Singapore.

Understanding the characteristic response of critical current, I c with stress/strain under magnetic field is important for the application of coated conductor (CC) tapes to large scale superconducting coils or magnets. In this study, the strain and magnetic field effects on I c in brass laminated reactive co-evaporation by deposition and reaction (RCE-DR) processed GdBCO CC tapes at 77 K were investigated. In the case of RCE-DR GdBCO CC tape samples with Hastelloy substrate, the additional lamination of brass foils to the Cu-stabilized only resulted in an increased irreversible strain limit of 0.50 % up to 0.80 %. But, not as much of these improvements were observed in CC samples having stainless steel substrate. Also, the additional brass laminate to all GdBCO CC tape samples did not affect the magnetic field response of Ic at 0 % strain. Under magnetic field, the strain response and tolerance of Ic was improved with additional brass laminates showing a much lower Ic reduction as compared with that at the irreversible strain limit of the Cu-stabilized CC samples. The strain sensitivity behavior of Ic under magnetic field (I c-ε-B relation at 77 K) in RCE-DR GdBCO CC tapes was discussed. © 2014 AIP Publishing LLC.

2G HTS coated conductor (CC) tapes are now used for electric device applications. The residual stress/strain induced in HTS coating films in CC tapes during cool down influences the critical current, Ic, and should be investigated. In this study, the thermal residual stress/strain induced in the REBCO coating film was calculated from deposition temperature (1073 K) to 77 K by thermo-mechanical analysis and numerical simulation. Additionally, the improvement in irreversible strain limit, εirr., with copper electroplating has been investigated. © 2002-2011 IEEE.

In this study, the homogeneity of critical current, Ic, along the lengthwise direction in the coated conductor (CC) tape under uniaxial tension was investigated using a multiple voltage tap configuration. Initially, a gradual and homogeneous Ic degradation occurred in all subsections of the tape up to a certain strain value. This was followed by an abrupt Ic degradation in some subsections, which caused scattering in Ic values along the length with increasing tension strain. The Ic degradation behaviour was also explained through n-value as well as microstructure analyses. Subsections showed Ic scattering corresponding to damaged areas of the CC tape revealed that transverse cracks were distributed throughout the gauge length. This homogeneous Ic degradation behaviour under tension is similar with the case under torsion strain but different with the case under hard bending which were previously reported. This behaviour is also different with the case using Bi-2223 HTS tapes under tension strain.

Rare-earth-Ba-Cu-O (REBCO) based coated conductors (CCs) are now being used for electric device applications. For coil-based applications such as motors, generators and magnets, the CC tape needs to have robust mechanical strength along both the longitudinal and transverse directions. The CC tape in these coils is subjected to transverse tensile stresses during cool-down and operation, which results in delamination within and between constituent layers. In this study, in order to explain the behaviour observed in the evaluation of c-axis delamination strength in Cu-stabilized GdBCO CC tapes by anvil tests, numerical analysis of the mechanical stress distribution within the CC tape has been performed. The upper anvil size was varied in the analysis to understand the effect of anvil size on stress distribution within the multilayered CC tape, which is closely related to the delamination strength, delamination mode and delamination sites that were experimentally observed. The numerical simulation results showed that, when an anvil size covering the whole tape width was used, the REBCO coating film was subjected to the largest stress, which could result in low mechanical delamination and electromechanical delamination strengths. Meanwhile, when smaller-sized anvils were used, the copper stabilizer layer would experience the largest stress among all the constituent layers of the CC tape, which could result in higher mechanical and electromechanical delamination strengths, as well as high scattering of both of these delamination strengths. As a whole, the numerical simulation results could explain the damage evolution observed in CC tapes tested under transverse tensile stress, as well as the transverse tensile stress response of the critical current, Ic. © 2014 IOP Publishing Ltd.

The electromechanical property behaviour of 2G coated conductor (CC) tapes fabricated by multi-layer deposition process both in the in-plane and transverse direction should be understood. The CC tapes are used in the fabrication of epoxy resin-impregnated coils. In such case, the Lorentz force due to the high magnetic field applied as well as the thermal stress due to the difference in coefficient of thermal expansion (CTE) among constituent layers during cooling to cryogenic temperature will induce transversely applied load to the surface of CC tapes in coils. Hence, the CC tape should have a good mechanical property in the transverse direction in order to maintain its superior performance under magnetic field. In this study, a test frame which gives precisely aligned transverse load was devised. Using the fixture, the delamination behaviours including the delamination strength of the GdBCO CC tapes under transverse tensile loading were investigated. Large variation on the delamination strength of the CC tapes was recorded and might have resulted from the slit edge effect and the inhomogeneity of the CC tapes. The Ic degradation behaviour under transverse load was related to the location where delamination occurred in the sample. © 2013 Elsevier B.V. All rights reserved.

Nonuniformity of critical current, Ic is one of the most important factors to be considered for the practical applications of high-temperature superconducting (HTS) REBCO coated conductors. To investigate the variation of Ic due to mechanical strain, local critical currents were measured at various tensile strain values from 0 to 1.2% for brass-laminated GdBCO tapes at 77 K, and analyzed using the Weibull distribution function. Measured local critical currents vary and decrease significantly at strain levels above about 0.8%. The Weibull function with three parameters turned out to be applicable for describing the Ic distribution of REBCO HTS wire for the entire strain range. The statistical minimum Ic calculated from the Weibull distribution function decreased with increased tensile strain. The degree of Ic variation was observed to drastically increase when the applied tensile strain exceeded the irreversible strain of about 0.8%. © 2013 IEEE.

The measurement of the coefficient of thermal expansion (CTE) of polypropylene laminated paper (PPLP) as electric insulating material is important for its practical superconducting device application. The thermal strain induced to HTS tapes and its insulating material during cooling from room temperature might largely affect the critical current (Ic) of HTS tapes. In this study, the thermal contraction of PPLP material was measured during cooling from 300 K to 77 K using double extensometers. Initially, the CTE of a brass tape was measured and it was compared with a reference data. It was found that the measured thermal expansion data of the brass material approaches that of the reference one. Based on the results, it was then confirmed that the measurement technique could be applied to thin and flexible samples. Therefore, the same measurement procedure was applied to PPLP material using double extensometers. As a result, the linear CTE of the PPLP at 77 K has been measured to be ~ 15. 3 × 10-6/K. Also, it was found that the thermal contraction characteristics of PPLP was dominated by polypropylene on the cross direction (higher thermal contraction) while it was dominated by Kraft paper on the machine direction (lower thermal contraction). Overall, this measurement procedure could be adopted for the determination of CTE of flexible materials such as PPLP.
