Learning a Physical Activity Classifier for a Low-power Embedded Wrist-located Device
This article presents and evaluates a novel algorithm for learning a physical
activity classifier for a low-power embedded wrist-located device. The overall
system is designed for real-time execution and it is implemented in the
commercial low-power System-on-Chips nRF51 and nRF52. Results were obtained
using a database composed of 140 users containing more than 340 hours of
labeled raw acceleration data. The final precision achieved for the most
important classes, (Rest, Walk, and Run), was of 96%, 94%, and 99% and it
generalizes to compound activities such as XC skiing or Housework. We conclude
with a benchmarking of the system in terms of memory footprint and power
consumption.Comment: Submitted to the 2018 IEEE International Conference on Biomedical and

Failures in Building Partnership for Success in the Competitive Market: The Case of Polish Ski Resorts
The topic of local stakeholders’ collaboration for success on the tourism market is a popular one, however research is usually devoted to well established Western economies. Created in this way, rules of cooperation are not fully suitable for new democracies in Central and Eastern European countries. Western standards of cooperation can not be achieved in Polish winter sports destinations, which is mirrored in the analyzed example of the Polish biggest ski resort – Szczyrk. Mutual mistrust and hostile attitude are typical for stakeholders in this example. The very low competitiveness level of the product is the most visible effect. Additionally, ski product development in Poland is highly criticized from the environmental point of view, which results in another difficult to manage, severe conflict sourced in different interpretations of the idea of sustainable tourism development.ski resort, partnership, Central and Eastern Europe, Polish ski industry
Surroundings and Snow: Ecosystem services related risks and opportunities at Canadian Mountain Holidays
Humanity has a complex relationship with the natural world. One aspect of this relationship is that of dependence on the services that the natural world provides. Commonly referred to as ecosystem services, these are services such as the provisioning of freshwater, timber, and medicines, the regulation of climate, and the maintenance of air quality. This relationship is especially important in the business realm, as most businesses are either directly or indirectly dependent on ecosystem service for their business offerings. This study explores such dependence in the form of business opportunities and risks associated with ecosystem services in Canadian Mountain Holidays (CMH), a well-established heli-skiing outfit operating out of British Columbia, Canada. In addition to being embedded in the natural world, this study revealed that CMH is dependent on a number of ecosystem services in order to provide their core business offering. Based on concepts established by the Millennium Ecosystem Assessment, this study uses the Corporate Ecosystem Service Review as an analytical framework to identify priority ecosystem services and their associated risks and opportunities within CMH’s main business offering. The implications of using the Corporate Ecosystem Services Review within the broader tourism context are also discussed
Economic Contributions of Winter Sports in a Changing Climate
In mountain towns across the United States that rely on winter tourism, snow is
currency. For snow lovers and the winter sports industry, predictions of a future with
warmer winters, reduced snowfall, and shorter snow seasons is inspiring them to
innovate, increase their own efforts to address emissions, and speak publicly on the
urgent need for action.
This report examines the economic contribution of winter snow sports tourism to
U.S. national and state-level economies. In a 2012 analysis, Protect Our Winters and
the Natural Resources Defense Council found that the winter sports tourism industry
generates 1.07 billion in aggregated
revenue over high and low snow years over the last decade
‘Where to ski?’: an ethnography of how guides make sense while planning
A ski guide’s job is to take recreational skiers into avalanche terrain. In this paper, we explore how ski guides make sense of complex social and ecological contexts while planning. Our data arises out of a one-year participant ethnography of ski guiding in Norway, and shows that guides work towards becoming socio-ecologically embedded by making sense of who the clients and what the mountain conditions are, in their determination of where to ski. Our work, through challenging and complementing the decision-making literature, shows how guides notice and act on cues, and through this embed themselves and their clients in the ecological context. We highlight the implications of these findings both for guides working in the outdoors and leisure recreationists
Rapid ascent: Rocky Mountain National Park in the Great Acceleration, 1945-present
2016 Summer.Includes bibliographical references.After the Second World War's conclusion, Rocky Mountain National Park (RMNP) experienced a massive rise in visitation. Mobilized by an affluent economy and a growing, auto-centric infrastructure, Americans rushed to RMNP in droves, setting off new concerns over the need for infrastructure improvements in the park. National parks across the country experienced similar explosions in visitation, inspiring utilities- and road-building campaigns throughout the park units administered by the National Park Service. The quasi-urbanization of parks like RMNP implicated the United States' public lands in a process of global change, whereby wartime technologies, cheap fossil fuels, and a culture of techno-optimism—epitomized by the Mission 66 development program—helped foster a "Great Acceleration" of human alterations of Earth’s natural systems. This transformation culminated in worldwide turns toward mass-urbanization, industrial agriculture, and globalized markets. The Great Acceleration, part of the Anthropocene—a new geologic epoch we have likely entered, which proposes that humans have become a force of geologic change—is used as a conceptual tool for understanding the connections between local and global changes which shaped the park after World War II. The Great Acceleration and its array of novel technologies and hydrocarbon-powered infrastructures produced specific cultures of tourism and management techniques within RMNP. After World War II, the park increasingly became the product and distillation of a fossil fuel-dependent society
