Spirituality is among the resources that many turn to as they deal with a diagnosis of advanced cancer. Researchers have made much progress in exploring and understanding spirituality's complex and multifaceted role in the midst of metastatic disease. As a result, spirituality is seen as an important aspect of a holistic and respectful approach to clinical care for patients and their loved ones. In this article, we provide a systematic review of the literature related to the interface between spirituality and metastatic cancer. We included articles published from January 2013 to June 2014. Twenty-two articles were reviewed, consisting of clinical intervention trials, association studies, surveys, qualitative studies, and review articles. The articles discussed efforts to improve patients' spiritual well-being, with relevant measurement scales; the associations of spirituality and end of life treatment practices; and efforts to better understand and meet the spiritual needs of patients and caregivers.

In order to evaluate the potential for detection and identification of underwater unexploded ordnance (UXO) by exploiting their structural acoustic response, we carried out broadband monostatic scattering measurements over a full 360 degrees on UXO's (two mortar rounds, an artillery shell, and a rocket warhead) and false targets (a cinder block and a large rock). The measurement band, 1-140 kHz, includes a low frequency structural acoustics region in which the wavelengths are comparable to or larger than the target characteristic dimensions. In general, there are aspects that provide relatively high target strength levels ( approximately -10 to -15 dB), and from our experience the targets should be detectable in this structural acoustics band in most acoustic environments. The rigid body scattering was also calculated for one UXO in order to highlight the measured scattering features involving elastic responses. The broadband scattering data should be able to support feature-based separation of UXO versus false targets and identification of various classes of UXO as well.

This paper investigates classification of submerged elastic targets using a sequence of backscattered acoustic signals corresponding to measurements at multiple target-sensor orientations. Wavefront and resonant features are extracted from each of the multiaspect signals using the method of matching pursuits, with a wave-based dictionary. A discrete hidden Markov model (HMM) is designed for each of the target classes under consideration, with identification of an unknown target effected by considering which model has the maximum likelihood of producing the observed sequence of feature vectors. HMMs are stochastic models which are well suited to describing piecewise-stationary processes, and are appropriate for multiaspect classification due to the strong aspect dependence of the scattered fields for most realistic targets. After establishing the physical and geometric correspondence between multiaspect sensing and the HMM parameters, performance is assessed through consideration of measured acoustic data from five similar submerged elastic targets. Results are presented with and without additive noise.

A chaplain-led spiritual life review is a feasible intervention for patients with neurodegenerative disease and results in beneficial effects on patients and SPs. Copyright © 2015 John Wiley & Sons, Ltd.

Research continues to establish the importance of spirituality for many persons with medical illnesses. This paper describes a pilot study titled, "Hear My Voice," designed to provide an opportunity for persons with progressive neurologic illnesses, including brain tumors and other neurodegenerative diseases, to review and discuss their spirituality with a board-certified chaplain, and to prepare a spiritual legacy document (SLD). First, we provide background information that underscores the importance of such a project for this patient population that is particularly vulnerable to cognitive impairment and communication difficulties. Second, we provide detailed methodology, including the semi-structured interview format used, the development of the SLD, and an overview of responses from participants and investigators. We also describe the quantitative and qualitative approaches to analysis taken with the aim of developing scientific validation in support of the Hear My Voice project.
