    Social Support in Nursing: A Review of the Literature

    Get PDF
    Nursing researchers have been investigating social support in the nursing profession with increasing interest, and the present manuscript reviews the state of the literature: methods, theories, and research findings related to social support in nursing. The aims of the existing research have focused primarily on understanding how the types, amount, and quality of social support received by nurses is associated with lower rates of professional stress, burnout, and intent to leave the profession. There is evidence that nurses in clinical settings value and are benefited by various forms of support from their supervisors. They also report lower distress when they have supportive personal relationships outside of work, although support from managers remains key. Support needs have been examined in different cultures and findings indicate that nursing in some parts of the world can be fraught because of cultural beliefs about the profession and about appropriate ways of enacting support. Less research has addressed the social support that nurses provide to patients and families. An agenda for advancing the literature is offered, with an emphasis on studying support from a communication perspective and learning more about what makes messages more or less supportive in nursing contexts

    Africa agriculture transformation scorecard performance and lessons for Malawi

    Get PDF
    In line with the continental commitment on mutual accountability, Malawi implemented the BR process to track progress in the implementation of the CAADP agenda, particularly the 2014 Malabo commitments. The process provided a platform for stakeholders in the agriculture sector (the public sector, private sector, development partners, civil society organizations, academia, and research institutions) to hold each other mutually accountable on both the financial and nonfinancial commitments they made on common development goals for the agriculture sector. The BR process also helped provide a platform for agriculture sector stakeholders to learn from each other (peer learning). The objective of this brief is to present Malawi’s performance and discuss lessons from the implementation of the inaugural CAADP BR mechanism

    Social facilitation for conservation planning: understanding fairy tern behavior and site selection in response to conspecific audio-visual cues

    Simulated social facilitation techniques (e.g. decoys and call playbacks) are commonly used to attract seabirds to restored and artificially created nesting habitats. However, a lack of social stimuli and conspecific cueing at these habitats may limit the use of these sites, at least in the short term. Therefore, testing the effectiveness of simulated audio-visual cues for attracting gregarious birds is important for conservation planning. In this study, we (1) assessed whether call playback and decoys were associated with an increased likelihood of Australian fairy terns Sternula nereis nereis visiting potentially suitable nesting habitats; (2) tested their behavioral response to different cues; and (3) documented whether social facilitation had the potential to encourage colony establishment. A full cross-over study design consisting of all possible pairings of decoy and call playback treatments (control [no attractants], decoys, call playback, both decoys and playback), allocated as part of a random block design, was undertaken at 2 sites. Linear modeling suggested that call playback was important in explaining the time spent aerial prospecting as well as the maximum number of fairy terns aerial prospecting, although this only appeared to be the case for 1 of the 2 sites. Decoys, on the other hand, did not appear to have any effect on time spent aerial prospecting. The results from this study suggest that audio cues have the potential to encourage site selection by increasing social stimuli, but attractants may be required over several breeding seasons before colonies are established

    Melt-quenched porous organic cage glasses

    The discrete molecular nature of porous organic cages (POCs) has allowed us to direct the formation of crystalline materials by crystal engineering. It has also been possible to create porous amorphous solids by deliberately disrupting the crystalline packing, either with chemical modification or by processing. More recently, organic cages were used to form isotropic porous liquids. However, the connection between solid and liquid states of POCs, and the glass state, are almost completely unexplored. Here, we investigate the melting and glass-forming behaviour of a range of organic cages, including both shapepersistent POCs formed by imine condensation, and reduced and synthetically post-modified amine POCs that are more flexible and lack shape-persistence. The organic cages exhibited melting and quenching of the resultant liquids provides molecular glasses. One of these molecular glasses exhibited improved gas uptake for both CO2 and CH4 compared to the starting amorphous cage. In addition, foaming of the liquid in one case resulted in a more stable and less soluble glass, which demonstrates the potential for an alternative approach to forming materials such as membranes without solution processing

    Swelling of compacted bentonite in organic solvents: Correlation of rate and extent of swelling with solvent properties

    Get PDF
    The swelling of clay minerals within shale formations during oil and gas exploration, and within compacted bentonite barriers for radioactive waste containment, presents a number of challenges to operators. Whilst much work has been devoted to understanding the interlayer swelling properties of clay mineral crystals, significantly less has been devoted to understanding coupled pore and interlayer swelling in reactive shale/compacted clay minerals. Here we study the swelling of compacted clay mineral tablets on exposure to a range of organic solvents, selected so that the effect of key solvent properties such as dielectric constant, density, octanol-water partition coefficient, viscosity and surface tension can be correlated with the swelling observed. We use a novel non-contact swelling meter to carry out the swelling tests, allowing us to access information on rate of swelling. Short-term swelling rate showed the strongest correlation to the solvent octanol-water partition coefficient. In long term swelling, good correlation was found between total linear swelling and viscosity, and the octanol-water partition coefficient

    Is pre-operative urodynamic bladder function the true predictor of outcome of male sling for post prostatectomy incontinence?

    PURPOSE: To investigate pre-operative urodynamic parameters in male sling patients to ascertain whether this might better predict surgical outcomes and facilitate patient selection. METHODS: We performed a retrospective, case notes and video-urodynamics, review of men who underwent AdVanceXP male sling in three London hospitals between 2012 and 2019. Urodynamics were performed in all centres, while retrograde leak point pressure (RLPP) was performed in one centre. RESULTS: Successful outcome was seen in 99/130 (76%) of men who required one pad or less per day. The dry rate was 51%. Pad usage was linked to worse surgical outcomes, mean 2.6 (range 1-6.5) for success vs 3.6 (range 1-10) although the ranges were wide (p = 0.002). 24 h pad weight also reached statistical significance (p = 0.05), with a mean of 181 g for success group versus 475 g for the non-successful group. The incidence of DO in the non-successful group was significantly higher than in successful group (55% versus 29%, p = 0.0009). Bladder capacity less than 250 ml was also associated with worse outcomes (p = 0.003). Reduced compliance was not correlated with outcomes (31% for success groups vs 45% for non-successful group, p = 0.15). Preoperative RLPP was performed in 60/130 patients but did not independently reach statistical significance (p = 0.25). CONCLUSION: Urodynamic parameters related to bladder function-detrusor overactivity and reduced maximum cystometric capacity predict male sling outcomes and may help in patient selection for male sling (or sphincter) surgery; whereas urodynamic parameters of sphincter incompetency (RLPP) were not predictive. Further larger scale studies are required to confirm these findings
