Senior Victorians and walking: obstacles and opportunities

This study investigate what supports and constrains walking for older adults.IntroductionWalking is particularly important for older adults, who are less likely than younger adults to participate in more vigorous forms of physical activity; more likely to experience social isolation; and less likely to have access to other forms of transport such as driving a car.Increasing recognition of the value of walking has led to a growing body of research into what supports and constrains everyday walking. However, much of this research and policy interest in ‘walkable’ neighbourhoods has focused on young and middle-aged population groups, and relatively little is known about what supports and constrains walking for older adults.This study addresses this knowledge gap through a unique and comprehensive investigation into:the meaning of walking for senior Victorians (aged 60 years and over); seniors’ walking behaviour: and supports and constraints on walking for seniors. The study comprises four components:a literature review of supports and constraints on seniors’ walking; analysis of seniors’ walking data from the Victorian Integrated Survey of Travel and Activity (VISTA); eight focus group discussions with a total of 32 senior Victorians; and a survey of 1128 senior Victorians

Beyond Health Care: New Directions to a Healthier America

Outlines recommendations for governments, schools, healthcare providers, philanthropies, and others to collaborate on implementing feasible, evidence-based interventions that create healthier communities and address the needs of those most at risk

Making up for lost time: Forging new connections between health and community development

New trends in the today’s public health world are making an important case for bringing public health and community development efforts together. These include the changing nature of 21st century preventable disease, the increasing link between health disparities and place, and the early positive evidence from early adopters of combined health and development strategies. Read about specific examples of efforts from King County, Washington that are capitalizing on these changes and simultaneously advancing both health and community development.Community development ; Health

Safety management of a complex R and D ground operating system

A perspective on safety program management was developed for a complex R&D operating system, such as the NASA-Lewis Research Center. Using a systems approach, hazardous operations are subjected to third-party reviews by designated-area safety committees and are maintained under safety permit controls. To insure personnel alertness, emergency containment forces and employees are trained in dry-run emergency simulation exercises. The keys to real safety effectiveness are top management support and visibility of residual risks

Risk-Aware Navigation for Mobile Robots in Unknown 3D Environments

Autonomous navigation in unknown 3D environments is a key issue for intelligent transportation, while still being an open problem. Conventionally, navigation risk has been focused on mitigating collisions with obstacles, neglecting the varying degrees of harm that collisions can cause. In this context, we propose a new risk-aware navigation framework, whose purpose is to directly handle interactions with the environment, including those involving minor collisions. We introduce a physically interpretable risk function that quantifies the maximum potential energy that the robot wheels absorb as a result of a collision. By considering this physical risk in navigation, our approach significantly broadens the spectrum of situations that the robot can undertake, such as speed bumps or small road curbs. Using this framework, we are able to plan safe trajectories that not only ensure safety but also actively address the risks arising from interactions with the environment.Comment: \copyright 2023 IEEE.
