    Nurses’ attitudes toward family witnessed resuscitation in Western Australian emergency departments

    Since 1982, healthcare institutions and professionals have been questioning whether family members should be allowed to enter resuscitation rooms during such critical period of treatment. A self-administered questionnaire is used in this research to investigate Western Australian emergency nurses’ attitudes towards family witnessed resuscitation and to explore possible factors influencing their attitudes.The findings of this work suggest that nurses, assuming a betwixt-between position, evaluate the costs and benefits of allowing family presence in the resuscitation room from patients, families and healthcare professionals’ perspectives. Nurses have an overwhelming agreement on the beneficial aspects of the practice, while also share concerns commonly reported in previous studies with an emphasis on a family member’s capability to cope with and comprehend the resuscitation procedures and a healthcare professional’s ability to handling pressure.Overall, the research suggests nurses are ambivalent in their attitude. Despite the nurses’ awareness of some family members’ desire to witness resuscitation and their reported benefits, in doing so, they are reluctant to initiate or formally incorporate this practice as a standard procedure. There is also a lack of consensus on the management of families’ presence, however, nurses agree on the need for preresuscitation assessment, support staff during resuscitation and post-resuscitation debriefing. Institutional factor is identified as a significant influence on nurses’ attitudes. This work will provide useful input in the future development of guidelines and will help stimulate discussion on this topic in Western Australia

    An East and West Debate on Human Rights

    Get PDF
    In an East and West debate on human rights, scholars from different cultures disagree on whether all civil and political rights are human rights. While they generally agree that basic civil rights such as rights against torture and slavery (i.e., physical security rights) are human rights, some of them argue that traditional political rights in the West such as freedom of speech and political participation (i.e., liberal rights) are not human rights. Some scholars, such as Daniel A. Bell, argue that liberal rights are not human rights because liberal rights conflict with some East Asian cultures. In this dissertation, I argue that both physical security rights and liberal rights are human rights, and explain the relationship between these rights and East Asian cultures. First, I argue that if liberal rights are not human rights because they conflict with some East Asian cultures, then physical security rights are also not human rights because physical security rights also conflict with some East Asian cultures. Next, I discuss the idea from Daniel Bell and Michael Walzer that physical security rights are human rights because they are minimal values. Based on their idea, I explain what minimal values are, and why it is possible to develop some maximal theories of physical security rights in East Asian cultures. I argue that since physical security rights are minimal values, they are still human rights even they conflict with some East Asian cultures. I then argue that liberal rights, similar to physical security rights, are also minimal values, and it is possible to develop some maximal theories of them in East Asian cultures. Therefore, similar to physical security rights, liberal rights are also human rights even they also conflict with some East Asian cultures. I also discuss other human rights debates, especially the debates between Daniel Bell and other philosophers. Charles Taylor argues for an overlapping consensus approach on human rights; Jack Donnelly argues for a Western liberalist approach on human rights. I explain the relationship between these approaches and my arguments, and how my arguments can help them to reply to the challenges from Daniel Bell

    Fluorination effect on electrochemistry of dibutyl viologen in aqueous solution

    Get PDF
    We have synthesized a perfluoro analog of dibutyl viologen by replacing the side –(CH2)2-CH2CH3 groups with –(CH2)2-C2F5 groups. The effect of fluorination on the aqueous solution electrochemistry was investigated using experimental voltammetric measurements and DFT computations. The formal potential of one-electron transfer redox couple, viologen radical monocation/dication, became 128 mV less negative upon fluorination, and the diffusion coefficient of the oxidized form was lowered by ca. 12%. Calculations indicated that the shift of the formal potential is largely caused by strong electron-withdrawing nature of the perfluorinated groups despite a separation of (CH2)2 from the viologen core. The effect is counter balanced by an opposite but smaller effect from the change of solvation free energy due to perfluorination. This perfluoro viologen is water-soluble in both oxidation states and is expected to be used as a redox probe at electrified oil-water and fluorous phase-water interfaces

    Hydrogen-atom Attack on Phenol and Toluene is \u3cem\u3eortho\u3c/em\u3e-directed

    The reaction of H + phenol and H/D + toluene has been studied in a supersonic expansion after electric discharge. The (1 + 1′) resonance-enhanced multiphoton ionization (REMPI) spectra of the reaction products, at m/z = parent + 1, or parent + 2 amu, were measured by scanning the first (resonance) laser. The resulting spectra are highly structured. Ionization energies were measured by scanning the second (ionization) laser, while the first laser was tuned to a specific transition. Theoretical calculations, benchmarked to the well-studied H + benzene → cyclohexadienyl radical reaction, were performed. The spectrum arising from the reaction of H + phenol is attributed solely to the ortho-hydroxy-cyclohexadienyl radical, which was found in two conformers (syn and anti). Similarly, the reaction of H/D + toluene formed solely the ortho isomer. The preference for the ortho isomer at 100–200 K in the molecular beam is attributed to kinetic, not thermodynamic effects, caused by an entrance channel barrier that is ∼5 kJ mol−1 lower for ortho than for other isomers. Based on these results, we predict that the reaction of H + phenol and H + toluene should still favour the ortho isomer under elevated temperature conditions in the early stages of combustion (200–400 °C)

    How accurate are approximate quantum chemical methods at modelling solute?solvent interactions in solvated clusters?

    In this paper, the performance of a wide range of DFT methods is assessed for the calculation of interaction energies of thermal clusters of a solute in water. Three different charge states (neutral, proton transfer transition state and zwitterion) of glycine were solvated by 1 to 40 water molecules as sampled from molecular dynamics simulations. While some ab initio composite methods that employ insufficiently large basis sets incurred significant errors even for a cluster containing only 5 water molecules relative to the W1X-2 benchmark, the DLPNO-CCSD(T)/CBS and DSD-PBEP86 (triple zeta basis set) levels of theory predicted very accurate interaction energies. These levels of theory were used to benchmark the performance of 16 density functionals from different rungs of Jacob\u27s Ladder. Of the Rung 4 functionals examined, the ωB97M-V and ωB97X-V functionals stood out for predicting absolute interaction energies in 40-water clusters with mean absolute deviations (MAD) ?4 kJ mol-1. The B3LYP-D3(BJ) functional performed exceptionally well with a MAD ?1.7 kJ mol-1 and is the overall best performing method. Calculations of relative interaction energies allow for cancellation of systematic errors, including basis set truncation and superposition errors, and the ωB97M-V and B3LYP-D3(BJ) double zeta basis set calculations yielded relative interaction energies that are within ?3 kJ mol-1 of the benchmark. The ONIOM approximation provides another strategy for accelerating the calculation of accurate absolute interaction energies provided that the calculations have converged with respect to the size of the "high-level-layer"
