Designing hardware for miniaturized robotics which mimics the capabilities of flying insects is of interest, because they share similar constraints (i.e. small size, low weight, and low energy consumption). Research in this area aims to enable robots with similarly efficient flight and cognitive abilities. Visual processing is important to flying insects' impressive flight capabilities, but currently, embodiment of insect-like visual systems is limited by the hardware systems available. Suitable hardware is either prohibitively expensive, difficult to reproduce, cannot accurately simulate insect vision characteristics, and/or is too heavy for small robotic platforms...

PURPOSE: To assess health care utilization and vision outcomes over 2 years in patients receiving bevacizumab treatment in clinical practice for diabetic macular edema. METHODS: Patients with newly diagnosed diabetic macular edema who received an intravitreal bevacizumab injection within 12 months of initial diagnosis were identified from Kaiser Permanente's 350,000 patients with diabetes mellitus treated between 2008 and 2013. Snellen best-corrected visual acuity (BCVA), number of intravitreal injections, and patient characteristics were abstracted from the electronic record...

Historically, the majority of nurses have been employed by hospitals. However, the changing landscape of health care has seen a shift to other areas of practice. Nursing graduates must be prepared to work collaboratively with a shared vision that is patientcentered and team-oriented. To better prepare students for collaborative practice, a School of Nursing developed a course for senior level nursing students that included a clinical experience within a student-run free clinic. Nursing students were able to enhance clinic services by providing health screening, patient navigation, patient education, health coaching, and patient follow-up...

The analysis of high-dimensional, possibly temporally misaligned, time-varying visual data is a fundamental task in disciplines such as image, vision, and behaviour computing. In this paper, we focus on dynamic facial behaviour analysis and in particular on the analysis of facial expressions. Distinct from the previous approaches, where sets of facial landmarks are used for face representation, raw pixel intensities are exploited for 1) unsupervised analysis of the temporal phases of facial expressions and facial action unitis (AUs) and 2) temporal alignment of a certain facial behaviour displayed by two different persons...

INTRODUCTION: Age-related macular degeneration (AMD) is a leading cause of blindness and low vision among older adults. Previous research shows a high prevalence of distress and disruption to the lifestyle of family caregivers of persons with late AMD. This supports existing evidence that caregivers are 'hidden patients' at risk of poor health outcomes. There is ample scope for improving the support available to caregivers, and further research should be undertaken into developing services that are tailored to the requirements of family caregivers of persons with AMD...

Programmatic approaches to assessment provide purposeful and meaningful assessment yet few examples of their development exist. The aim of this study was to describe the development of a programme of assessment using a participatory action research (PAR) approach. Nine work-based assessors together with three academics met on six occasions to explore the current approach to competency-based assessment in the placement component of a dietetics university course, the findings of which were used to design a programme of assessment...

REVIEW
Francesca De Felice, Pierre Blanchard
It might seem odd that a special issue about Gianni Bonadonna would publish a review on radiation-induced neurocognitive dysfunction. Dr. Gianni Bonadonna is considered a pioneer in medical oncology history, mainly due to new and revolutionary treatment approaches proposed in breast cancer and Hodgkin lymphoma. He had an active role in the field of medical oncology, especially through lectures and textbooks. He shared his considerable insight of understanding cancer behavior and evaluating research advances over the years to prevent tumor recurrence and preserve patients from unnecessary toxicity...

REVIEW
Michael W Country
The retina is part of the central nervous system, and shares the characteristically high metabolism of the brain. The high energy demand of the retina is normally matched with a large supply of metabolites. When supply does not equal demand (e.g. if retinal blood flow is impaired), retinal neurons are at risk of excitotoxic cell death and vision is impaired or lost. Understanding the energetic budget of the retina is therefore crucial for understanding the pathology and treatment of retinal disease. In this minireview I give an overview of the energetics of the retina, with a focus on lessons learnt from comparative physiology...

The vision for Australia's national electronic health record system included empowering consumers to become active participants in their own health care. This paper aims to critically review the literature on consumer perspectives of Australia's My Health Record (formerly PCEHR). The review is based on a subset of articles (n=12) identified in the Australian EHR Repository (N=143), a repository of metadata of Australian Research on EHR located at Flinders University. Results show low levels of awareness and concerns about sharing records and equity of access for all Australians, which in view of the change from opt in to opt out raises concerns about explicit consent...

The visual systems of all animals are used to provide information that can guide behaviour. In some cases insects demonstrate particularly impressive visually-guided behaviour and then we might reasonably ask how the low-resolution vision and limited neural resources of insects are tuned to particular behavioural strategies. Such questions are of interest to both biologists and to engineers seeking to emulate insect-level performance with lightweight hardware. One behaviour that insects share with many animals is the use of learnt visual information for navigation...

State Medicaid programs need cost-effective strategies to provide high-quality care that is accessible to individuals with low incomes and limited resources. Integrated delivery systems have been formed to provide care across the continuum, but creating a shared vision for improving community health can be challenging. Medical Home Network was created as a network of primary care providers and hospital systems providing care to Medicaid enrollees, guided by the principles of egalitarian governance, practice-level care coordination, real-time electronic alerts, and pay-for-performance incentives...

BACKGROUND: Research has shown that the modes of leadership and management may influence health outcomes. However, majority of health leaders and managers in many low-income countries are promoted on account of clinical expertise. It has been recognised that these new managers are often ill-prepared for managing complex health systems. In response to this challenge, the Zambian Ministry of Health (MoH) has developed the Governance and Management Capacity Building (GMCB) Strategic Plan (2012-2016), whose overarching goal is to improve health sector governance and create an environment that is result-oriented, accountable and transparent...

Matthew Renze
Visual snow is a symptom described as the continuous perception of tiny flickering dots in the entire field of vision, similar to static of an analog television. Visual snow syndrome is a cluster of symptoms found highly prevalent in patients that present with visual snow. While most of these symptoms appear to be visual in nature, approximately 63% of patients studied also report continuous bilateral tinnitus. The high correlation of visual-snow-syndrome patients presenting with tinnitus suggests that they may share a common underlying pathophysiology...

Assigning behavioral functions to neural structures has long been a central goal in neuroscience and is a necessary first step toward a circuit-level understanding of how the brain generates behavior. Here, we map the neural substrates of locomotion and social behaviors for Drosophila melanogaster using automated machine-vision and machine-learning techniques. From videos of 400,000 flies, we quantified the behavioral effects of activating 2,204 genetically targeted populations of neurons. We combined a novel quantification of anatomy with our behavioral analysis to create brain-behavior correlation maps, which are shared as browsable web pages and interactive software...

Unlike vision, the mechanisms underlying auditory motion perception are poorly understood. Here we describe an auditory motion illusion revealing a novel cue to auditory speed perception: the temporal frequency of amplitude modulation (AM-frequency), typical for rattling sounds. Naturally, corrugated objects sliding across each other generate rattling sounds whose AM-frequency tends to directly correlate with speed. We found that AM-frequency modulates auditory speed perception in a highly systematic fashion: moving sounds with higher AM-frequency are perceived as moving faster than sounds with lower AM-frequency...

A number of vision problems such as zero-shot learning and person re-identification can be considered as cross-class transfer learning problems. As mid-level semantic properties shared cross different object classes, attributes have been studied extensively for knowledge-transfer across classes. Most previous attribute learning methods focus only on human-defined/nameable semantic attributes, whilst ignoring the fact there also exist undefined/latent shareable visual properties, or latent attributes. These latent attributes can be either discriminative or non-discriminative parts depending on whether they can contribute to an object recognition task...
