Who actually wants to use ‘the killer app’? Perceptions of location based services in the young and old

This paper describes the results of two qualitative case studies that assessed the perceptions of Location Based Services (LBS) with two UK user groups: a family with a behaviour-disordered teenager, and a group of older adults. The family (n=2) and older adults (n=13) were interviewed individually after experiencing LBS. The data from the interviews were thematically analysed with the aid of Nvivo software, and organised into themes to better understand attitudes towards LBS technology. Whilst both groups had the opportunity to use, adapt to and experience LBS, perceptions of ‘cool’ and ‘trendiness’ affected judgments of it, and their subsequent usage intentions. The family adopted the LBS system fully, with the device aiding navigation, and ultimately developing trust. Their teenage son also embraced the technology, aided in part by the unobtrusive and ‘trendy’ nature of the mobile phone the LBS was deployed on. In contrast, the older adults felt that LBS could not assist them in any way, and were concerned about the potential for invasions of privacy. This work highlights clear generational differences in the acceptance of LBS, and suggests consideration is needed for the future design of LBS to ensure suitability for the user

Does Your Boss Know Where You Are? Predicting Adoption of LBS in the Workplace

To date there has been no tested model to predict uptake of LBS services in a real world setting. The leading theoretical contribution to our understanding of attitudes and behaviour towards LBS comes from Junglas & Spitzmüller (2005). They hypothesised that intentions to use LBS would be influenced by technology characteristics, task characteristics, personality type, perceived privacy, perceived usefulness, trust and perceived risk. We developed a questionnaire to test and refine their model with a UK employed population

The impact of using location-based services with a behaviour-disordered child

In this paper we explore technologies that help parents locate their children. Parents regularly use mobile phones to stay in touch with their children, but recent developments in location-based tracking allow parents to assess the location of their child directly. Such location-based services offer new assurances, but also bring new privacy challenges. In order to explore these, we conducted a case study focussing on the way in which a family has used location-based technologies to keep track of a child with Aspergers Syndrome and Attention Deficit Hyperactivity Disorder. This novel research shows that Location-Based Services, although usually applied to lone-worker situations, can be effectively applied to other user groups. The parents of the child were interviewed at length, and the interview was analysed using qualitative methods. The findings are discussed and considered against a current predictive model of LBS use

Eco-terrorism or Eco-tage: An Argument for the Proper Frame

What does the term “terrorism” mean? Is it accurate to lump illegal acts that destroy property but carefully avoid harming people into the same category as acts clearly intended to kill? Is this a difference of kind or just of degree? While we (the authors) don\u27t generally endorse the destruction of property as a method of generating social change, we believe that the destruction of property is fundamentally different from the intentional killing of people; therefore, to label acts of obstruction, trespassing, vandalism, sabotage, or arson as “terrorism” is inaccurate and has the potential to damage one\u27s understanding of real acts of terrorism, thereby reducing the potency of the term. We started this project with a hunch. In recent years, we have observed frequent use of the term “eco-terrorism,” in the news media and in conversations, in reference to the acts of environmentalists. Our observations were anecdotal, and we wanted to be sure they were accurate. We found no literature analyzing cultural acceptance of the term “eco-terrorism”; therefore, before embarking on an ethical analysis of this phenomenon, we set out to confirm our casual observation that the term was widely used in the United States. We conducted an analysis of the use of the term in US newspapers across a period of nearly 11 years. Our analysis indicates broad acceptance of the term among both journalists and their sources, making it all the more important to understand both the history and the implications of labeling obstruction, trespassing, vandalism, sabotage, and arson as “eco-terrorism.

Constraints on models with universal extra dimensions from dilepton searches at the LHC

Models with universal extra dimensions predict that each Standard Model particle is accompanied by a tower of Kaluza-Klein resonances. Canonical searches for the production and cascade decays of first Kaluza-Klein modes through missing transverse momentum signatures suffer in general from low detection efficiencies because of the rather compressed Kaluza-Klein particle mass spectrum. Here, instead we analyze signatures from the production of second Kaluza-Klein states which can decay into Standard Model particles and thus do not result in any missing transverse momentum. Such signatures provide a strong sensitivity, and are of particular interest as they would allow for a clear distinction between extra dimension models and other models of new physics like supersymmetry. We constrain the production of second Kaluza-Klein particles from recent LHC searches for dilepton resonances, and place limits on the compactification scale to be larger than 715GeV, and on the masses of the second Kaluza-Klein particles to be larger than 1.4TeV.Comment: 11 pages, 4 figures, analysis updated (inclusion of data from CMS-PAS-EXO-12-061), MUED bound improved to R^{-1} > 715 GeV, version published in JHE

Trends and Potential Interactions Between Pinnipeds and Fisheries of New England and the U.S. West Coast

Long-term trends in the abundance and distribution of several pinniped species and commercially important fisheries of New England and the contiguous U.S. west coast are reviewed, and their actual and potential interactions discussed. Emphasis is on biological interactions or competition. The pinnipeds include the western North Atlantic stock of harbor seals, Phoca vitulina concolor; western North Atlantic gray seals, Halochoerus grypus; the U.S. stock of California sea lions, Zalophus californianus californianus; the eastern stock of Steller sea lions, Eumetopias jubatus; and Pacific harbor seals, Phoca vitulina richardii. Fisheries included are those for Atlantic cod, Gadus morhua; silver hake, Merluccius bilinearis; Atlantic herring, Clupea harengus; the coastal stock of Pacific whiting, Merluccius productus; market squid, Loligo opalescens; northern anchovy, Engraulis mordax; Pacific her-ring, Clupea pallasi; and Pacific sardine, Sardinops sagax. Most of these pinniped populations have grown exponentially since passage of the U.S. Marine Mammal Protection Act in 1972. They exploit a broad prey assemblage that includes several commercially valuable species. Direct competition with fisheries is therefore possible, as is competition for the prey of commercially valuable fish. The expanding pinniped populations, fluctuations in commercial fish biomass, and level of exploitation by the fisheries may affect this potential for competition. Concerns over pinnipeds impacting fisheries (especially those with localized spawning stocks or at low biomass levels) are more prevalent than concerns over fisheries’ impacts on pinnipeds. This review provides a framework to further evaluate potential biological interactions between these pinniped populations and the commercial fisheries with which they occur

Biomechanical demands of the 2-step transitional gait cycles linking level gait and stair descent gait in older women

Stair descent is an inherently complex form of locomotion posing a high falls risk for older adults, specifically when negotiating the transitional gait cycles linking level gait and descent. The aim of this study was to enhance our understanding of the biomechanical demands by comparing the demands of these transitions. Lower limb kinematics and kinetics of the 2-step transitions linking level and descent gait at the top (level-to-descent) and the bottom (descent-to-level) of the staircase were quantified in 36 older women with no falls history. Despite undergoing the same vertical displacement (2-steps), the following significant (p<.05) differences were observed during the top transition compared to the bottom transition: reduced step velocity; reduced hip extension and increased ankle dorsiflexion (late stance/pre-swing); reduced ground reaction forces, larger knee extensor moments and powers (absorption; late stance); reduced ankle plantarflexor moments (early and late stance) and increased ankle powers (mid-stance). Top transition biomechanics were similar to those reported previously for continuous descent. Kinetic differences at the knee and ankle signify the contrasting and prominent functions of controlled lowering during the top transition and forward continuance during the bottom transition. The varying musculoskeletal demands encountered during each functional sub-task should be addressed in falls prevention programmes with elderly populations where the greatest clinical impact may be achieved. Knee extensor eccentric power through flexion exercises would facilitate a smooth transition at the top and improving ankle plantarflexion strength during single and double limb stance activities would ease the transition into level gait following continuous descent
