    The marine protected area planning process in Washington state: Recommendations for increased effectiveness

    Get PDF
    In Washington State, the Department of Natural Resources (WA DNR) is responsible for managing state-owned aquatic lands. Aquatic reserves are one of many Marine Protected Area (MPA) designations in WA State that aim to protect sensitive aquatic and ecological habitat. We analyzed the designation and early planning processes of WA State aquatic reserves, identified gaps in the processes, and recommend action to improve the WA State aquatic reserve early planning approach.

    Age related cognitive impairments and assistive web-base technology

    Get PDF
    Several researchers argue that age related cognitive impairments have detrimental affect on use of web services by older adults. However little and systematic applied research has been conducted on how age related cognitive impairments might affect the usage of web services by older adults. Undoubtedly, understanding the relationship between the cognitive changes that accompany aging and their impact on older adults’ usage of web services will be beneficial for designing web services for this group. The paper demonstrates how such understanding has been employed to develop an assistive technology in order to improve older adults’ interaction with online forms

    Efficient Video Indexing on the Web: A System that Leverages User Interactions with a Video Player

    In this paper, we propose a user-based video indexing method, that automatically generates thumbnails of the most important scenes of an online video stream, by analyzing users' interactions with a web video player. As a test bench to verify our idea we have extended the YouTube video player into the VideoSkip system. In addition, VideoSkip uses a web-database (Google Application Engine) to keep a record of some important parameters, such as the timing of basic user actions (play, pause, skip). Moreover, we implemented an algorithm that selects representative thumbnails. Finally, we populated the system with data from an experiment with nine users. We found that the VideoSkip system indexes video content by leveraging implicit users interactions, such as pause and thirty seconds skip. Our early findings point toward improvements of the web video player and its thumbnail generation technique. The VideSkip system could compliment content-based algorithms, in order to achieve efficient video-indexing in difficult videos, such as lectures or sports.Comment: 9 pages, 3 figures, UCMedia 2010: 2nd International ICST Conference on User Centric Medi

    Patient perceptions of epinephrine auto-injectors: Exploring barriers to use

    Get PDF
    Background: In recent years, government initiatives have proposed that patient self-care should serve as a key resource in response to the anticipated increase in global demand for health care. However, if patients are to be empowered as self-carers, barriers to engagement must be identified and overcome. Anaphylaxis is an increasingly common life threatening allergic reaction. Patients at risk of anaphylaxis are prescribed epinephrine auto-injectors and play a crucial role in delivering their own care and management of this condition. One key recommendation is that patients routinely carry an epinephrine auto-injector with them, and deploy the device when needed. However, only a small proportion of patients that require epinephrine actually receive it. Objective: To explore the reasons why patients who have been prescribed epinephrine auto-injectors fail to adhere to self-care and management recommendations. Methods: In-depth interviews with 15 adults who have been prescribed epinephrine auto-injectors were carried out to explore the barriers that exist in the provision of effective self-care and management of anaphylaxis. Results: Inconsistent health professional advice, perceived stigma of carrying a ‘weapon-like’ device, poor device design and limited patient training were identified as barriers to carriage or use. Patients were reluctant to carry devices in public because of perceived and observed stigma and suspicion. They were happy to ignore expiry dates and some participants were confident that the emergency services would provide them with the appropriate care they needed, and therefore did not carry the device in urban areas. Conclusions and clinical implications: Improved training of patients, the public and health professionals around both the carriage and use of auto-injectors are areas for urgent attention if improved levels of self-care are to be attained. The design of epinephrine auto-injectors should also receive attention as patients often fail to carry them due to size and aesthetics.

    The Age-shift: observations on social policy, ageism and the dynamics of the adult lifecourse

    Get PDF
    Through a critical engagement with policy trends, we ask how shifts in ideologies of ageing might influence the possibilities available to adults as they grow older. Of particular interest are the implications for how people are being encouraged to think about the adult lifecourse. We address these questions by looking at policy development, taking the 2000–2005 period in the UK as a case example, and by comparing this period to wider regional and international trends. Finally, we assess the implications of contemporary policy, from a psychodynamic point of view, for the maintenance of a viable identity in later life and for intergenerational relationships

    Theory underlying the peripheral vision horizon device

    Get PDF
    Peripheral Vision Horizon Device (PVHD) theory states that the likelihood of pilot disorientation in flight is reduced by providing an artificial horizon that provides orientation information to peripheral vision. In considering the validity of the theory, three areas are explored: the use of an artificial horizon device over some other flight instrument; the use of peripheral vision over foveal vision; and the evidence that peripheral vision is well suited to the processing of orientation information

    Transformational government and assistive web base technologies

    Get PDF
    Transformational government has been on the European agenda for several years. However, progress towards realising the full potential of ICT to transform public services for older adults with age related cognitive impairments has been very limited. Highlighting such limitations this paper demonstrates how assistive web base technologies can be developed to improve the public services for older adults with age related cognitive impairments. However the paper argues that these transformations can be obstructed if there is no strong leadership and political commitment from people at many levels in public sectors and governments

    Baby Boomers & adult Ageing: Issues for Social and Public policy

    Get PDF
    This paper provides a critical assessment of academic and policy approaches to population ageing with an emphasis on the baby boomer cohort and constructions of late-life identity. It is suggested that policy towards an ageing population has shifted in focus, away from particular social hazards and towards an attempt to re-engineer the meaning of legitimate ageing and social participation in later life. Three themes are identified: constructing the baby boomers as a force for social change, a downward drift of the age associated with 'older people' and a shift away from defining ageing identities through consumption, bacl towards work and production. The paper concludes with a discussion of the implications for future social and public policy
