Metallic nanostructures now play an important role in many applications. In particular, for the emerging fields of plasmonics and nanophotonics, the ability to engineer metals on nanometric scales allows the development of new devices and the study of exciting physics. This review focuses on top-down nanofabrication techniques for engineering metallic nanostructures, along with computational and experimental characterization techniques. A variety of current and emerging applications are also covered. © 2012 IOP Publishing Ltd. Source

This research examined the proposal that ineffective responses to common interpersonal problems disrupt youths' relationships, which, in turn, contributes to depression during adolescence. Youth (86 girls, 81 boys; M age = 12.41, SD = 1.19) and their primary female caregivers participated in a three-wave longitudinal study. Youth completed a measure assessing interpersonal stress responses; youth and caregivers completed semi-structured interviews assessing youths' life stress and psychopathology. Consistent with the hypothesized model, ineffective stress responses (low levels of effortful engagement, high levels of involuntary engagement and disengagement) predicted the generation of subsequent interpersonal stress, which partially accounted for the association between stress responses and depression over time. Moreover, results revealed that self-generated interpersonal, but not noninterpersonal stress, predicted depression, and that this explanatory model was specific to the prediction of depression but not anxiety. This research builds on interpersonal stress generation models of depression, and highlights the importance of implementing depression-focused intervention programs that promote effective stress responses and adaptive interpersonal relationships during adolescence. © 2011 Springer Science+Business Media, LLC.

Background: Little research has been published from a global perspective regarding needs of nurses and midwives related to perinatal bereavement. Objective: To identify needs and concerns of US and Spanish nurses and midwives who have worked with perinatal death and to identify the bereavement interventions they use to help families with this experience. Methods: A cross-sectional study was conducted. Data were collected in 2011 from US (n=44) and Spanish (n=15) nurses and midwives via a questionnaire. Results: Statistically significant differences between the nurses/midwives in each country were found regarding needs relating to knowledge, communication skills and managing personal feelings. Interventions of accompanying, listening, offering keepsakes, baptism discussion, and funeral planning were also found to be significantly different between the two groups. Conclusions: These findings demonstrate a continued need to increase the standard and consistency of perinatal bereavement care worldwide. Bereavement education in nursing curricula and practice settings in both cultures is essential to increase the standard of care. © 2015 MA Healthcare Ltd. Source

Because of the ongoing nursing shortage and the increasing acuity of patients, new graduate nurses must master both psychomotor and critical thinking skills rapidly. Inadequate orientation leads to high turnover rates for new graduates. Health care leaders must examine the competencies needed for new graduate nurses to succeed in this environment. A critical review of studies (n = 26) was conducted to identify crucial competencies that are needed for new graduate nurses to be successful. Six areas were identified in which new graduates lacked competence: communication, leadership, organization, critical thinking, specific situations, and stress management. Strategies were identified to improve the transition of new graduates. Hospitals should consider implementing nurse residency programs that include strategies for clear communication and conflict management, prioritization skills, and leadership development. Schools of nursing should add communication strategies to their current focus on critical thinking, clinical reasoning, and simulation scenarios and include situation-specific skills such as end-of-life scenarios. Further research should focus on stress management, leadership, clinical reasoning, and evaluation of measurement tools for new graduates. © SLACK Incorporated. Source

Employing kinetic Monte Carlo, we simulated the radical chain propagation of the pyrolysis of phenethyl phenyl ether (PPE), which serves as a model compound for the β-O-4 linkage in lignin. The input rate constants were obtained with transition state theory based on density functional calculations. Pre- and postcomplexes for hydrogen abstraction and β-scission reactions were included assuming thermal equilibrium. Individual rate constants compare well with experimental estimates. The calculated overall α/β-product selectivity is qualitatively in agreement with experiment. The simulation revealed that the carbon-carbon phenyl shift reaction for the β-PPE radical is part of the pyrolysis mechanism. © 2012 Elsevier B.V. All rights reserved. Source
