A spatial heterodyne spectrometer (SHS) is described for standoff laser-induced breakdown spectroscopy (LIBS) measurements. The spatial heterodyne LIBS spectrometer (SHLS) is a diffraction grating based interferometer with no moving parts that offers a very large field of view, high light throughput, and high spectral resolution in a small package. The field of view of the SHLS spectrometer is shown to be ∼1° in standoff LIBS measurements. In the SHLS system described here, the collection aperture was defined by the 10 mm diffraction gratings in the SHS and standoff LIBS measurements were made up to 20 m with no additional collection optics, corresponding to a collection solid angle of 0...

Polymeric membranes are widely used for salt removal, but mechanism of ion permeation is still insufficiently understood. Here we analyze ion transport and scaling in polymers relevant to desalination (dense aromatic polyamide Nomex and cellulose acetate, CA) using impedance spectroscopy (EIS), focusing on the effects of the salt type, concentration and pH. The results highlight the role of proton uptake in ion permeation. For Nomex the exceptionally high affinity to proton results in a power-low dependence of conductivity on salt concentrations with an unusual exponent 1/2...

This final rule revises the conditions of participation (CoPs) that home health agencies (HHAs) must meet in order to participate in the Medicare and Medicaid programs. The requirements focus on the care delivered to patients by HHAs, reflect an interdisciplinary view of patient care, allow HHAs greater flexibility in meeting quality care standards, and eliminate unnecessary procedural requirements. These changes are an integral part of our overall effort to achieve broad- based, measurable improvements in the quality of care furnished through the Medicare and Medicaid programs, while at the same time eliminating unnecessary procedural burdens on providers...

REVIEW
D J Saxby, D G Lloyd
Inappropriate biomechanics, namely wear-and-tear, has been long believed to be a main cause of osteoarthritis (OA). However, this view is now being re-evaluated, especially when examined alongside mechanobiology and new biomechanical studies. These are multiscale experimental and computational studies focussing on cell- and tissue-level mechanobiology through to organ- and whole-body-level biomechanics, which focuses on the biomechanical and biochemical environment of the joint tissues. This review examined papers from April 2015 to April 2016, with a focus on multiscale experimental and computational biomechanical studies of OA...

Johannes Mahr, Gergely Csibra
Episodic memory has been analyzed in a number of different ways in both philosophy and psychology, and most controversy has centered on its self-referential, 'autonoetic' character. Here, we offer a comprehensive characterization of episodic memory in representational terms, and propose a novel functional account on this basis. We argue that episodic memory should be understood as a distinctive epistemic attitude taken towards an event simulation. On this view, episodic memory has a metarepresentational format and should not be equated with beliefs about the past...

Neutrophils were among the first leukocytes described and visualized by early immunologists. Prominent effector functions during infection and sterile inflammation classically placed them low in the immune tree as rapid, mindless aggressors with poor regulatory functions. This view is currently under reassessment as we uncover new aspects of their life cycle and identify transcriptional and phenotypic diversity that endows them with regulatory properties that extend beyond their lifetime in the circulation...

A shift in focus from symptoms and disability towards the capacity and potential of the person with dementia is urgently needed to create a more balanced view of dementia and a more dementia-friendly society, which enables people and their families to adapt to the changes dementia brings in their lives. The new concept of social health suggested by Huber and colleagues seems helpful to make such a shift. In this dedicated special issue, a consensus-based operationalization of the concept of social health in dementia is proposed and several aspects of social health and related dementia care are addressed within the framework of European collaborative projects of the INTERDEM network...

Materials with well-defined architectures are heavily sought after in view of their diverse technological applications. Among the desired target architectures, lamellar phases stand out for their exceptional mechanical and optical features. Here we show that charged colloids, decorated on their poles with two oppositely charged regions possess the unusual ability to spontaneously assemble in different morphologies of (semi-)ordered, layered particle arrangements which maintain their structural stability over a surprisingly large temperature range...

BACKGROUND: Our medical college is running a mentoring programme for undergraduate medical students since 2009. The academic leadership of the college identified the need to change the focus of the programme from mere problem- solving to professional and personal development of mentees. METHODS: A core group of faculty designed and implemented a workshop on mentoring for 28 mentors. The workshop included reflections on the participants' previous experiences about mentoring, discussion on perceptions of mentees about the existing mentoring programme, self-analysis of mentoring skills, overview of the Surrendering, Accepting, Gifting and Extending (SAGE) model and demonstration of effective mentoring skills using role plays and a film...

Parents demonstrate an important influence on adolescent obesity and dietary behavior; yet, family-based obesity interventions continue to exhibit limited success among adolescents. To further inform family-based approaches for adolescent obesity treatment, we examined the perceptions of adolescent females with obesity and their mothers of the influences experienced within the parent-adolescent relationship that affect everyday dietary practices. We conducted six focus group interviews (three adolescent female and three mother) among 15 adolescent (12-17 years old) females with obesity and 12 of their mothers...

BACKGROUND: Increasingly, the experiences and perceptions of parents who decline vaccination are the subject of investigation. However, the experiences of clinicians who encounter these parents in the course of their work has received little academic attention to date. This study aimed to understand the challenges faced and strategies used when general practitioners and immunising nurses encounter parents who choose not to vaccinate their children. METHODS: Primary care providers were recruited from regions identified through the Australian Childhood Immunisation Register (ACIR) as having higher than national average rates of registered objection to childhood vaccination...

REVIEW

Wnt/β-catenin signaling is an important cell-to-cell signaling mechanism that controls gene expression during embryonic development and is critically implicated in human diseases. Developmental, cellular, and transcriptional responses to Wnt signaling are remarkably context-specific in different biological processes. While nuclear localization of β-catenin is the key to activation of the Wnt/β-catenin pathway and target gene expression, the molecular mechanisms of how the same Wnt/β-catenin signaling pathway induces specific responses remain undetermined...

Surveying endangered species is necessary to evaluate conservation effectiveness. Camera trapping and biometric computer vision are recent technological advances. They have impacted on the methods applicable to field surveys and these methods have gained significant momentum over the last decade. Yet, most researchers inspect footage manually and few studies have used automated semantic processing of video trap data from the field. The particular aim of this study is to evaluate methods that incorporate automated face detection technology as an aid to estimate site use of two chimpanzee communities based on camera trapping...

AIM: The problem of family care for people dependent on another person has only recently become a focus of research. As demand for health and social services has not been adequately met by public service providers, growing attention has been given to informal care and the integration of families within systems of health and social care at the community level. This paper presents the results of a survey on informal carers' views and opinions under the current conditions of social support in the Czech Republic...

Today, we can see a trend towards increased psychosocial strain at work among home care managers and staff. The aim of this study is to describe home care managers' views on their own psychosocial working conditions and on how to promote workplace health and safety in a municipality in northern Sweden. A mixed methods design was used, including questionnaire and qualitative focus group data. The qualitative data were analysed by manifest content analysis. The results indicate that most managers perceived increased variety in work and opportunities for development at work, but at the same time increased demands...

Drug addiction implicates both reward learning and homeostatic regulation mechanisms of the brain. This has stimulated 2 partially successful theoretical perspectives on addiction. Many important aspects of addiction, however, remain to be explained within a single, unified framework that integrates the 2 mechanisms. Building upon a recently developed homeostatic reinforcement learning theory, the authors focus on a key transition stage of addiction that is well modeled in animals, escalation of drug use, and propose a computational theory of cocaine addiction where cocaine reinforces behavior due to its rapid homeostatic corrective effect, whereas its chronic use induces slow and long-lasting changes in homeostatic setpoint...
