    Directory of Open Access Journals (Sweden)

    Mary Jane P. Spink


    Full Text Available This article is a contribution to the understanding of risk-adventure as the set of practices that recuperate the positive dimension of risk. Based on a review of the literature and on the theoretical approach of Constructionist Discursive Psychology, it proposes a model for the analysis of the dimensions of risk adventure present in adventure tourism and radical sports: risk/danger, adrenaline, adventure, training, use of equipments and relationship to nature. The data, derived from the site of a tourism agency that specialized in adventure tourism and an interview with a paraglide practitioner, was analyzed using "trees of association of ideas" and "dialogical maps". All the elements of the model were present in both modalities of risk-adventure. However, adventure tourism was characterized by the delegation of responsibility to specialists, whilst the training/experience dimension made itself more present in radical sports, along with greater emphasis on individual responsibility in the control of risks.

  1. The South African Adventure Tourism Economy: An urban phenomenon

    Directory of Open Access Journals (Sweden)

    McKay Tracey


    Full Text Available The international adventure tourism literature is remarkably silent on the geographical nature of the industry. This study seeks to provide a geographical analysis of the sector within the context of South Africa. The spatial analysis was undertaken by metropolitan area, secondary towns and small towns, using a dataset of adventure tourism enterprises. It was found that the sector is spatially concentrated and highly urbanised, despite the perception that adventure tourism requires ‘wild’ and outdoor spaces. With many adventure tourism enterprises located in South Africa’s metropolitan areas, it is a hither too unknown sub-sector of the South African urban tourism market. Urban settlements with large populations and a strong general tourism sector form a significant support base for adventure tourism operators. Cape Town is the dominant adventure tourism destination, making it the adventure capital of South Africa. A few small settlements were found to be highly dependent upon the sector for survival.

  17. Aging Adventure Athletes Assess Achievements and Alter Aspirations to Maintain Self-Esteem. (United States)

    Buckley, Ralf C


    Achievements and capabilities influence the self-esteem of skilled adventure athletes. Self-esteem affects individual mental health. Aging commonly reduces adventure capabilities. To avoid loss in self-esteem, aging adventure athletes are forced to adjust their aspirations. Here, I examine this process using participant observation, ethnographic and autoethnographic approaches. The qualitative data for this analysis are derived from 60 years' experience in outdoor adventure activities, and ∼30,000 person-hours of participant observation. I argue that individuals assess their own capabilities against a set of specific feats. For some activities, successful completion of a specific feat is known as nailing it. The selection of these feats depends on factors such as activity and geographic location, as well as individual experience and peer comparisons. I examine the detailed process using a single feat repeated over a period of decades, the bubble-line kayak run through Lava Falls on the Grand Canyon of the Colorado River. I compare other examples of nail or fail to construct a general framework for self-esteem in aging adventure athletes, with both physical and psychological feedback loops. I also identify two key thresholds, as aging adventure athletes recognize their declining skills. These may apply to aging more broadly, beyond outdoor adventure.

I examine the detailed process using a single feat repeated over a period of decades, the bubble-line kayak run through Lava Falls on the Grand Canyon of the Colorado River. I compare other examples of nail or fail to construct a general framework for self-esteem in aging adventure athletes, with both physical and psychological feedback loops. I also identify two key thresholds, as aging adventure athletes recognize their declining skills. These may apply to aging more broadly, beyond outdoor adventure.

  19. The adventure of numbers

    CERN Document Server

    Godefroy, Gilles


    Numbers are fascinating. The fascination begins in childhood, when we first learn to count. It continues as we learn arithmetic, algebra, geometry, and so on. Eventually, we learn that numbers not only help us to measure the world, but also to understand it and, to some extent, to control it. In The Adventure of Numbers, Gilles Godefroy follows the thread of our expanding understanding of numbers to lead us through the history of mathematics. His goal is to share the joy of discovering and understanding this great adventure of the mind. The development of mathematics has been punctuated by a n

  20. Adventure and Extreme Sports. (United States)

    Gomez, Andrew Thomas; Rao, Ashwin


    Adventure and extreme sports often involve unpredictable and inhospitable environments, high velocities, and stunts. These activities vary widely and include sports like BASE jumping, snowboarding, kayaking, and surfing. Increasing interest and participation in adventure and extreme sports warrants understanding by clinicians to facilitate prevention, identification, and treatment of injuries unique to each sport. This article covers alpine skiing and snowboarding, skateboarding, surfing, bungee jumping, BASE jumping, and whitewater sports with emphasis on epidemiology, demographics, general injury mechanisms, specific injuries, chronic injuries, fatality data, and prevention. Overall, most injuries are related to overuse, trauma, and environmental or microbial exposure. Copyright © 2016 Elsevier Inc. All rights reserved.

  3. Adventure tourism and adventure sports injury: the New Zealand experience. (United States)

    Bentley, Tim A; Page, Stephen J; Macky, Keith A


    The primary aims of this study were to establish a client injury baseline for the New Zealand adventure tourism and adventure sport sector, and to examine patterns and trends in claims for injury during participation in adventure activities. Content analysis of narrative text data for compensated injuries occurring in a place for recreation and sport over a 12-month period produced over 15,000 cases involving adventure tourism and adventure sport. As found in previous studies in New Zealand, highest claim counts were observed for activities that are often undertaken independently, rather than commercially. Horse riding, tramping, surfing and mountain biking were found to have highest claim counts, while hang gliding/paragliding/parasailing and jet boating injuries had highest claim costs, suggesting greatest injury severity. Highest claim incidence was observed for horse riding, with female claimants over-represented for this activity. Younger male claimants comprised the largest proportion of adventure injuries, and falls were the most common injury mechanism.

  4. It's Time for an Adventure (United States)

    Eldam Pommer, R.


    In recent years, studies have repeatedly illustrated the significance of children seeing themselves reflected in careers and cultures that they may not typically identify with. The current lack of diversity in accessible media, however, limits the potential for self-reflection from children of different socioeconomic, racial, and gender identity backgrounds. This isolates substantial sections of our population from experiencing these moments of recognition and inspiration. As scientists in a rapidly evolving field that requires diversity in perspective and ideas, it is incumbent upon us to innovate new ways to engage with these future generations in the pursuit of inspiring future earth scientists. Inspired by the work of others (e.g. Doc McStuffins, The Sandwich Swap) and through a successful crowdfunding campaign, I was able to develop a project which integrates children's love of adventure with foundational critical thinking skills. That project is MD and Finn. MD and Finn is a self-written/published children's book series which was developed to address the lack of diversity in children's literature. MD is a little girl who continuously explores, discovers, and builds the world around her with her best friend, Finn the fox. They encourage one another to ask questions, brainstorm, make mistakes, and learn from absolutely everything. While the primary goal of the series is to create a character in which young girls can see themselves solving problems, learning from mistakes, and enjoying the little pieces of science in daily life, as the project progresses, characters from different races, ethnicities, gender identities, religions, and disabilities are purposefully introduced. In bringing these books to life, I have been given the unique opportunity to regularly engage with classrooms and families who may be meeting an actual scientist for the very first time. For a few young girls, they may also finally be seeing just a little bit of themselves - in a lab coat

  8. A Review of Adventure Learning

    Directory of Open Access Journals (Sweden)

    George Veletsianos


    Full Text Available Adventure learning (AL is an approach for the design of digitally-enhanced teaching and learning environments driven by a framework of guidelines grounded on experiential and inquiry-based education. The purpose of this paper is to review the adventure learning literature and to describe the status quo of the practice by identifying the current knowledge, misconceptions, and future opportunities in adventure learning. Specifically, the authors present an integrative analysis of the adventure learning literature, identify knowledge gaps, present future research directions, and discuss research methods and approaches that may improve the AL approach.The authors engaged in a systematic search strategy to identify adventure learning studies then applied a set of criteria to decide whether to include or exclude each study. Results from the systematic review were combined, analyzed, and critiqued inductively using the constant comparative method and weaved together using the qualitative metasynthesis approach.Results indicate the appeal and promise of the adventure learning approach. Nevertheless, the authors recommend further investigation of the approach. Along with studies that investigate learning outcomes, aspects of the AL approach that are engaging, and the nature of expert-learner collaboration, future adventure learning projects that focus on higher education and are (a small and (b diverse can yield significant knowledge into adventure learning. Research and design in this area will benefit by taking an activity theory and design-based research perspective.

  14. Educação ao ar livre pela aventura: o aprendizado de valores morais em expedições à natureza Education outdoors through adventure: learning moral values in nature expeditions

    Directory of Open Access Journals (Sweden)

    Flavio Theodor Kunreuther


    investigates student's learning according to their own perceptions and to those of the educators, with an emphasis on the moral development of the individual. As part of the case study with a teenage student who took part in one of the courses, a psychologist who coordinates a shelter for minors was also interviewed. The results indicate that open air education courses are characterized by experiences that stimulate teamwork, debates about justice and solidarity, and reflections about values and principles such as courage, personal effort, discipline, respect, and the overcoming of limits. The results also indicate that this educational proposal yields experiences of the senses and of connection with nature. Although there is an educational potential for education outdoors, the action of the educator with the students is fundamental to produce physically and psychologically safe experiences that reach their pedagogical potential for the development of morality, and help people to develop environmental awareness manifested through the concrete actions of those who return from the courses to their communities of origin.

  12. The Analysis of Fourth Adventure of Seven-Adventures of Iranian National Epic based on Myth

    Directory of Open Access Journals (Sweden)

    GH Ebrahimi


    Full Text Available The seven-adventures of Rostam, in particular, and other Iranian seven-adventures such as Esfandyar seven-adventures or Gorshasp pseudo-seven-adventures are a kind of eternity search, a kind of battle with selfhood that aims to facilitate the problems, the difficulties of evolution way and human ascent. By discussing and analyzing Iranian seven-adventures, this research aims to study the fourth adventure of all the seven-adventures, which is, at the surface, the battle between man (hero, champion and woman but, in essence, it is the battle between fire and water. Fire is the son of Ahura Mazda and water is its enemy. Water, which was at one time the symbol of holiness and purity of Ahura, became a satanic element during Sassanid era and following the dominance of Zorvani thoughts on religious system of that time. By analyzing Rostam, Esfandyar, Gorshasp, Heracles fourth adventure and looking at Zal and Roodabe stories, Khajavi Kermani’s Sam-Nameh, Nezemi’s Khosro and Shirin and Mahmoud Dolatabadi’s Kalidar, we try to prove this hypothesis.

  13. Outdoors classes (United States)

    Szymanska-Markowska, Barbara


    Why should students be trapped within the four walls of the classroom when there are a lot of ideas to have lessons led in the different way? I am not a fan of having lessons at school. For many students it is also boring to stay only at school, too. So I decided to organize workshops and trips to Universities or outdoors. I created KMO ( Discoverer's Club for Teenagers) at my school where students gave me some ideas and we started to make them real. I teach at school where students don't like science. I try hard to change their point of view about it. That's why I started to take parts in different competitions with my students. Last year we measured noise everywhere by the use of applications on a tablet to convince them that noise is very harmful for our body and us. We examined that the most harmful noises were at school's breaks, near the motorways and in the households. We also proved that acoustic screens, which were near the motorways, didn't protect us from noise. We measured that 30 meters from the screens the noise is the same as the motorway. We won the main prize for these measurements. We also got awards for calculating the costs of a car supplied by powered by a solar panel. We measured everything by computer. This year we decided to write an essay about trees and weather. We went to the forest and found the cut trees because we wanted to read the age of tree from the stump. I hadn't known earlier that we could read the weather from the tree's grain. We examined a lot of trees and we can tell that trees are good carriers of information about weather and natural disasters. I started studies safety education and I have a lot of ideas how to get my students interested in this subject that is similar to P.E., physics and chemistry, too. I hope that I will use my abilities from European Space Education Resource Office and GIFT workshop. I plan to use satellite and space to teach my students how they can check information about terrorism, floods or other

  18. Safety in New Zealand's adventure tourism industry: the client accident experience of adventure tourism operators. (United States)

    Bentley , T A; Page, S J; Laird, I S


    Injuries and fatalities among participants of adventure tourism activities have the potential to seriously impact on New Zealand's tourism industry. However, the absence of statistics for tourist accidents in New Zealand, and the lack of detailed academic research into adventure tourism safety, means the extent of the problem is unknown. The aims of the present study were to determine the incidence of client injuries across a range of adventure tourism activity sectors, and to identify common accident events and contributory risk factors. A postal questionnaire survey of New Zealand adventure tourism operators was used. Operators were asked to provide information related to their business; the number of recorded client injuries during the preceding 12 month period, January to December 1998; common accident and injury events associated with their activity; and perceived risk factors for accidents in their sector of the adventure tourism industry. The survey was responded to by 142 New Zealand adventure tourism operators. The operators' reported client injury experience suggests the incidence of serious client injuries is very low. Highest client injury incidence rates were found for activities that involved the risk of falling from a moving vehicle or animal (e.g., cycle tours, quad biking, horse riding, and white-water rafting). Slips, trips, and falls on the level were common accident events across most sectors of the industry. Perceived accident/incident causes were most commonly related to the client, and in particular, failure to attend to and follow instructions. The prevalence of client injuries in activity sectors not presently covered by government regulation, suggests policy makers should look again at extending codes of practice to a wider range of adventure tourism activities. Further research considering adventure tourism involvement in overseas visitor hospitalized injuries in New Zealand, is currently in progress. This will provide supporting evidence

  19. The aesthetic and cultural pursuits of patients with stroke. (United States)

    O'Connell, Clare; Cassidy, Aoife; O'Neill, Desmond; Moss, Hilary


    There has been an increasing interest in the arts in health care, with a suggestion that the arts and aesthetics can augment patient outcomes in stroke and other illnesses. Designing such programmes requires better knowledge of the artistic, aesthetic, and cultural pursuits of people affected by stroke. The aim of this study was to obtain the insights of this group about the profile of art and aesthetic activities in their lives and the influence of stroke on these aspects. Patients attending a stroke service were administered questions adapted from the Irish Arts Council's 2006 questionnaire on participation in aesthetics and cultural pursuits. Information was also collected on stroke type and present functional and cognitive status. Thirty-eight patients were interviewed. Of these, 20 were inpatients in hospital at the time of the interview and 18 were interviewed in an outpatient setting. Popular activities included mainstream cinema, listening to music, dancing, attending plays or musicals, and being outdoors. Many patients ceased these activities after their stroke, mostly because of health issues and inaccessibility. Most of the patients valued the importance of the arts in the health-care setting. This study gives a perspective for the first time on the aesthetic and cultural pursuits of stroke patients before their stroke. It portrays a wide variety of cultural and leisure activities and the cessation of these poststroke. It revealed the restrictions patients felt on gaining access to leisure pursuits both while in hospital and following discharge. Copyright © 2013 National Stroke Association.

Early adventures involved developing ''state-vector models'' for specific harmful effects (cell killing, life shortening) of exposure to radiation. More recent adventures led to developing ''hazard-function models'' for predicting biological effects (e.g., cell killing, mutations, tumor induction) of combined exposure to different toxicants. Hazard-function models were also developed for predicting harm to man from exposure to large radiation doses. Major conclusions derived from the modeling adventures are as follows: (1) synergistic effects of different genotoxic agents should not occur at low doses; (2) for exposure of the lung or bone marrow to large doses of photon radiation, low rates of exposure should be better tolerated than high rates; and (3) for some types of radiation (e.g., alpha particles and fission neutrons), moderate doses delivered at a low rate may be more harmful than the same dose given at a high rate. 53 refs., 7 figs

  8. Pursuit Latency for Chromatic Targets (United States)

    Mulligan, Jeffrey B.; Ellis, Stephen R. (Technical Monitor)


    The temporal dynamics of eye movement response to a change in direction of stimulus motion has been used to compare the processing speeds of different types of stimuli (Mulligan, ARVO '97). In this study, the pursuit response to colored targets was measured to test the hypothesis that the slow response of the chromatic system (as measured using traditional temporal sensitivity measures such as contrast sensitivity) results in increased eye movement latencies. Subjects viewed a small (0.4 deg) Gaussian spot which moved downward at a speed of 6.6 deg/sec. At a variable time during the trajectory, the dot's direction of motion changed by 30 degrees, either to the right or left. Subjects were instructed to pursue the spot. Eye movements were measured using a video ophthalmoscope with an angular resolution of approximately 1 arc min and a temporal sampling rate of 60 Hz. Stimuli were modulated in chrominance for a variety of hue directions, combined with a range of small luminance increments and decrements, to insure that some of the stimuli fell in the subjects' equiluminance planes. The smooth portions of the resulting eye movement traces were fit by convolving the stimulus velocity with an exponential having variable onset latency, time constant and amplitude. Smooth eye movements with few saccades were observed for all stimuli. Pursuit responses to stimuli having a significant luminance component are well-fit by exponentials having latencies and time constants on the order of 100 msec. Increases in pursuit response latency on the order of 100-200 msec are observed in response to certain stimuli, which occur in pairs of complementary hues, corresponding to the intersection of the stimulus section with the subjects' equiluminant plane. Smooth eye movements can be made in response to purely chromatic stimuli, but are slower than responses to stimuli with a luminance component.

  9. Adventure tourists in Pretoria, South Africa: A demographic profile

    Directory of Open Access Journals (Sweden)

    MJ Lötter


    Full Text Available Adventure activities and experiences constantly evolve because individuals, motives, behaviours, and experiences differ and change over time. In order to assist adventure tourism companies to promote and sell specific activities and experiences that will meet the specific needs and wants of their identified target markets, this paper focuses on the demographic profile of adventure tourists who used the products/services of adventure tourism companies within Pretoria, South Africa. The realised sample was 234, providing a 93.6% response rate. The research instrument used was a self-completing questionnaire. Based on the results, these adventure tourists were Afrikaans speaking individuals between the ages of twenty-eight and forty-nine years. Their households consisted of two to four people and there were generally two income earners per household. This study established that there is a need for further researching of comprehensive adventure tourist profiles.

    Juan Felipe Tsao Borrero


    Full Text Available Adventure tourism is a growing sector within the tourism industry and understanding its dynamics is fundamental for adventure tourism destinations and their local authorities. Destination benchmarking is a strong tool to identify the performance of tourism services offered at the destination in order to design appropriate policies to improve its competitiveness. The benchmarking study of Suesca, an adventure tourism destination in Colombia, helps to identify the gaps compared with successful adventure tourism destinations around the world, and provides valuable information to local policy-makers on the features to be improved. The lack of available information to tourists and financial facilities hinders the capability of Suesca to improve its competitiveness.

    with popular medievalism and the figure of the bold chivalric knight intersected with bourgeois forms of venture capitalism; the resulting children’s adventure narratives attempt to negotiate and even combine these two very different forms of risk-taking. Next, I will explore the rise of fantasy literature......This project will examine representations of risk in children’s literature from the mid-nineteenth century to the present day. It will explore how issues of risk and trust have been mediated through children’s narratives, and how the adventurous child has served, and continues to serve...... for children following the Second World War. There are numerous overviews of trends within children’s literature during this period, but little exists that links these trends with their immediate sociocultural context and with changing attitudes towards childhood during the aftermath of the war...

    Globalization can be thought of as the widening, deepening and quickening of the worldwide interconnections in social, cultural, political and economic life (Held et al., 1999). For adventure sports enthusiasts from the West, this has opened up the world for them to pursue their activities in more ‘exotic’ natural locations. Marketing of adventure holidays has increased with the greater ease of travelling to suitable geographical locations, providing apparently ‘authentic’ adventure experienc...

    Full Text Available Tourism is a kind of human activity, which has the ability to simultaneously satisfy a wide human needs’ range and develop people’s personality. Adventure tourism term is a type of tourism able to fulfill these types of human needs. The aim of the study was to know the Polish tourists opinion about the adventure tourism in Poland. The study involved 50 people, taking into account their gender, age, education and occupational status. The research tool was a survey questionnaire. The study indicated that it is not a popular form of tourism in Poland. Its proponents, the information about places and facilities derive mainly from the Internet. The most popular forms are trekking, tramping, caves exploration, paintball, windsurfing, bungejumping and rafting. Rather average possibility of practicing the adventure tourism in Poland is associated with multitude barriers, mainly financial investments, lack of free time, as well as fear and general fear of some of its forms.

  18. Injuries to New Zealanders participating in adventure tourism and adventure sports: an analysis of Accident Compensation Corporation (ACC) claims. (United States)

    Bentley, Tim; Macky, Keith; Edwards, Jo


    The aim of this study was to examine the involvement of adventure tourism and adventure sports activity in injury claims made to the Accident Compensation Corporation (ACC). Epidemiological analysis of ACC claims for the period, July 2004 to June 2005, where adventure activities were involved in the injury. 18,697 adventure tourism and adventure sports injury claims were identified from the data, representing 28 activity sectors. Injuries were most common during the summer months, and were most frequently located in the major population centres. The majority of injuries were incurred by claimants in the 20-50 years age groups, although claimants over 50 years of age had highest claims costs. Males incurred 60% of all claims. Four activities (horse riding, mountain biking, tramping/hiking, and surfing) were responsible for approximately 60% of all adventure tourism and adventure sports-related injuries. Slips, trips, and falls were the most common injury initiating events, and injuries were most often to the back/spine, shoulder, and knee. These findings suggest the need to investigate whether regulatory intervention in the form of codes of practice for high injury count activities such as horse riding and mountain biking may be necessary. Health promotion messages and education programs should focus on these and other high-injury risk areas. Improved risk management practices are required for commercial adventure tourism and adventure sports operators in New Zealand if safety is to be improved across this sector.

  19. Perceptual learning modifies untrained pursuit eye movements. (United States)

    Szpiro, Sarit F A; Spering, Miriam; Carrasco, Marisa


    Perceptual learning improves detection and discrimination of relevant visual information in mature humans, revealing sensory plasticity. Whether visual perceptual learning affects motor responses is unknown. Here we implemented a protocol that enabled us to address this question. We tested a perceptual response (motion direction estimation, in which observers overestimate motion direction away from a reference) and a motor response (voluntary smooth pursuit eye movements). Perceptual training led to greater overestimation and, remarkably, it modified untrained smooth pursuit. In contrast, pursuit training did not affect overestimation in either pursuit or perception, even though observers in both training groups were exposed to the same stimuli for the same time period. A second experiment revealed that estimation training also improved discrimination, indicating that overestimation may optimize perceptual sensitivity. Hence, active perceptual training is necessary to alter perceptual responses, and an acquired change in perception suffices to modify pursuit, a motor response. © 2014 ARVO.

The authors discuss numerous historical aspects and provide biographical details on influential contributors to the field, including emails from Thomas Hales and Ken Brakke. With examples from physics, crystallography, engineering, and biology, this accessible and whimsical bo...

  1. The pursuit of perfect packing

    CERN Document Server

    Weaire, Denis


    In 1998 Thomas Hales dramatically announced the solution of a problem that has long teased eminent mathematicians: what is the densest possible arrangement of identical spheres? The Pursuit of Perfect Packing recounts the story of this problem and many others that have to do with packing things together. The examples are taken from mathematics, physics, biology, and engineering, including the arrangement of soap bubbles in foam, atoms in a crystal, the architecture of the bee''s honeycomb, and the structure of the Giant''s Causeway. Using an informal style and with key references, the book also includes brief accounts of the lives of many of the scientists who devoted themselves to problems of packing over many centuries, together with wry comments on their efforts. It is an entertaining introduction to the field for both specialists and the more general public.

  8. Outdoor thermal comfort. (United States)

    Nikolopoulou, Marialena


    A review of the various approaches in understanding outdoor thermal comfort is presented. The emphasis on field surveys from around the world, particularly across Europe, enables us to understand thermal perception and evaluate outdoor thermal comfort conditions. The consistent low correlations between objective microclimatic variables, subjective thermal sensation and comfort outdoors, internationally, suggest that thermophysiology alone does not adequate describe these relationships. Focusing on the concept of adaptation, it tries to explain how this influences outdoor comfort, enabling us to inhabit and get satisfaction from outdoor spaces throughout the year. Beyond acclimatization and behavioral adaptation, through adjustments in clothing and changes to the metabolic heat, psychological adaptation plays a critical role to ensure thermal comfort and satisfaction with the outdoor environment. Such parameters include recent experiences and expectations; personal choice and perceived control, more important than whether that control is actually exercised; and the need for positive environmental stimulation suggesting that thermal neutrality is not a pre-requisite for thermal comfort. Ultimately, enhancing environmental diversity can influence thermal perception and experience of open spaces.

  9. In Pursuit of Internal Waves (United States)

    Peacock, Thomas


    Orders of magnitude larger than surface waves, and so powerful that their generation impacts the lunar orbit, internal waves, propagating disturbances of a density-stratified fluid, are ubiquitous throughout the ocean and atmosphere. Following the discovery of the phenomenon of ``dead water'' by early Arctic explorers and the classic laboratory visualizations of the curious St. Andrew's Cross internal wave pattern, there has been a resurgence of interest in internal waves, inspired by their pivotal roles in local environmental and global climate processes, and their profound impact on ocean and aerospace engineering. We detail our widespread pursuit of internal waves through theoretical modeling, laboratory experiments and field studies, from the Pacific Ocean one thousand miles north and south of Hawaii, to the South China Sea, and on to the Arctic Ocean. We also describe our recent expedition to surf the most striking internal wave phenomenon of them all: the Morning Glory cloud in remote Northwest Australia. This work was supported by the National Science Foundation through a CAREER Grant OCE-064559 and through Grants OCE-1129757 and OCE-1357434, and by the Office of Naval Research through Grants N00014-09-1-0282, N00014-08-1-0390 and N00014-05-1-0575.

  10. The safety experience of New Zealand adventure tourism operators. (United States)

    Bentley, Tim A; Page, Stephen; Walker, Linda


    This survey examined parameters of the New Zealand adventure tourism industry client injury risk. The research also sought to establish priorities for intervention to reduce adventure tourism risk, and identify client injury control measures currently in place (or absent) in the New Zealand adventure tourism industry, with a view to establishing guidelines for the development of effective adventure tourism safety management systems. This 2003 survey builds upon an exploratory study of New Zealand adventure tourism safety conducted by us during 1999. A postal questionnaire was used to survey all identifiable New Zealand adventure tourism operators. The questionnaire asked respondents about their recorded client injury experience, perceptions of client injury risk factors, safety management practices, and barriers to safety. Some 27 adventure tourism activities were represented among the responding sample (n=96). The highest client injury risk was reported in the snow sports, bungee jumping and horse riding sectors, although serious underreporting of minor injuries was evident across the industry. Slips, trips and falls (STF) were the major client injury mechanisms, and a range of risk factors for client injuries were identified. Safety management measures were inconsistently applied across the industry. The industry should consider the implications of poor injury reporting standards and safety management practices generally. Specifically, the industry should consider risk management that focuses on minor (e.g., STF) as well as catastrophic events.

  20. Autistic phenomena in The Adventures of Pinocchio. (United States)

    Smith, Adrian


    This paper seeks to demonstrate that the protagonist of Carlo Collodi's The Adventures of Pinocchio illustrates numerous autistic phenomena such as communication difficulties, sensory and perceptual distortions and mindblindness. While Pinocchio is viewed as a literary construct with contraindications of autism, it will be argued that his autistic traits are sufficient to suggest the possibility that Collodi had a partial intuition of the syndrome 60 years before it was identified by Leo Kanner. Approaching Collodi's text in this manner is taken as an opportunity to survey and reflect upon the psychoanalytic literature on autism and to position it in relation to contemporary theories from cognitive neuroscience. © 2017, The Society of Analytical Psychology.

    Full Text Available Cyanobacteria, or the blue-green algae as they used to be called until 1974, are the oldest oxygenic photosynthesizers. We summarize here adventures with them since the early 1960s. This includes studies on light absorption by cyanobacteria, excitation energy transfer at room temperature down to liquid helium temperature, fluorescence (kinetics as well as spectra and its relationship to photosynthesis, and afterglow (or thermoluminescence from them. Further, we summarize experiments on their two-light reaction - two-pigment system, as well as the unique role of bicarbonate (hydrogen carbonate on the electron acceptor side of their photosystem II, PSII. This review, in addition, includes a discussion on the regulation of changes in phycobilins (mostly in PSII and chlorophyll a (Chl a; mostly in photosystem I, PSI under oscillating light, on the relationship of the slow fluorescence increase (the so-called S to M rise, especially in the presence of diuron in minute time scale with the so-called state-changes, and on the possibility of limited oxygen evolution in mixotrophic PSI (minus mutants, up to 30 minutes, in the presence of glucose.

  10. SOTUNKI: An Island Of Education and Adventure

    Directory of Open Access Journals (Sweden)

    Heidi HEIKKILÄ


    Full Text Available Last year some of the teachers of Sotunki Distance Learning Centre set out to find a new approach to teaching different subjects in Upper Secondary School. We wanted to do this by using social media and finally decided on using Second Life. I think social media like Second Life can offer a lot to our students who study via internet and rarely meet each other or their teachers. In Second Life students can meet their teachers, guidance counselors and fellow students face to face and in real time. This brings more interaction to the learning process and gives the students a chance to get to know each other. Also the interaction in Second Life is slightly different – it gives us teachers a different kind of chance to get to know our students better in a more informal way. There were many decisions to make when we first started building our school. We started by deciding on whether we wanted to have a traditional school building with traditional classrooms in it – and decided against it. Why repeat the real world in Second Life? What is the point of using a virtual world if not to benefit from the possibilities that the real world does not have? So we set out to do something new and extraordinary: instead of a school house we have a mountainous jungle waiting for explorers, and instead of classrooms we have lots of different innovations customized to fit the virtual world. It is important to us that students want to explore our island and learn while exploring it: learning can be a real adventure.I chose the course of history of literature as my project because Second Life has wonderful tools for creating historical settings.

  11. Indoor and Outdoor Allergies. (United States)

    Singh, Madhavi; Hays, Amy


    In last 30 to 40 years there has been a significant increase in the incidence of allergy. This increase cannot be explained by genetic factors alone. Increasing air pollution and its interaction with biological allergens along with changing lifestyles are contributing factors. Dust mites, molds, and animal allergens contribute to most of the sensitization in the indoor setting. Tree and grass pollens are the leading allergens in the outdoor setting. Worsening air pollution and increasing particulate matter worsen allergy symptoms and associated morbidity. Cross-sensitization of allergens is common. Treatment involves avoidance of allergens, modifying lifestyle, medical treatment, and immunotherapy. Copyright © 2016 Elsevier Inc. All rights reserved.

  12. Efference copy failure during smooth pursuit eye movements in schizophrenia. (United States)

    Spering, Miriam; Dias, Elisa C; Sanchez, Jamie L; Schütz, Alexander C; Javitt, Daniel C


    Abnormal smooth pursuit eye movements in patients with schizophrenia are often considered a consequence of impaired motion perception. Here we used a novel motion prediction task to assess the effects of abnormal pursuit on perception in human patients. Schizophrenia patients (n = 15) and healthy controls (n = 16) judged whether a briefly presented moving target ("ball") would hit/miss a stationary vertical line segment ("goal"). To relate prediction performance and pursuit directly, we manipulated eye movements: in half of the trials, observers smoothly tracked the ball; in the other half, they fixated on the goal. Strict quality criteria ensured that pursuit was initiated and that fixation was maintained. Controls were significantly better in trajectory prediction during pursuit than during fixation, their performance increased with presentation duration, and their pursuit gain and perceptual judgments were correlated. Such perceptual benefits during pursuit may be due to the use of extraretinal motion information estimated from an efference copy signal. With an overall lower performance in pursuit and perception, patients showed no such pursuit advantage and no correlation between pursuit gain and perception. Although patients' pursuit showed normal improvement with longer duration, their prediction performance failed to benefit from duration increases. This dissociation indicates relatively intact early visual motion processing, but a failure to use efference copy information. Impaired efference function in the sensory system may represent a general deficit in schizophrenia and thus contribute to symptoms and functional outcome impairments associated with the disorder.

  13. Dynamics of multiple-goal pursuit. (United States)

    Louro, Maria J; Pieters, Rik; Zeelenberg, Marcel


    The authors propose and test a model of multiple-goal pursuit that specifies how individuals allocate effort among multiple goals over time. The model predicts that whether individuals decide to step up effort, coast, abandon the current goal, or switch to pursue another goal is determined jointly by the emotions that flow from prior goal progress and the proximity to future goal attainment, and proximally determined by changes in expectancies about goal attainment. Results from a longitudinal diary study and 2 experiments show that positive and negative goal-related emotions can have diametrically opposing effects on goal-directed behavior, depending on the individual's proximity to goal attainment. The findings resolve contrasting predictions about the influence of positive and negative emotions in volitional behavior, critically amend the goal gradient hypothesis, and provide new insights into the dynamics and determinants of multiple-goal pursuit.

    Directory of Open Access Journals (Sweden)

    Irena Smetáčková


    Full Text Available Outdoor school is a stable element of Czech educational system. However,many changes have occurred during the last twenty years in the purposes of outdoorschools and in their organization. The article presents various school statistics andresults of research which included questionnaire survey in elementary schools in Pragueand a case study of two classes. The study found that the outdoor school programmesare getting shorter, budgets for outdoor schools are reduced, and prices of outdoorschool programmes for parents are increasing. Because of high prices, almost 20 % ofpupils cannot attend outdoor schools. Nevertheless, according to teachers, pupils andparents, the main purpose of outdoor school programmes is to create a better socialclimate in peer groups. Because of high rates of absence, this goal is partly invalid.Another purpose should be that teachers and children get to know each other better.This goal is invalid as well because many schools hire commercial agencies which limitsthe time that pupils and teachers spend together.

  3. Significant profile differences among male and female adventure tourists in Pretoria, South Africa

    Directory of Open Access Journals (Sweden)

    Melissa Jeanette Lötter


    Full Text Available Different adventure activities/experiences evolve because individuals, their motives, behaviours, and experiences differ and change over time. This notion illustrates the broad nature of adventure tourism and its links with other forms of tourism. In turn, adventure tourism companies are compelled to promote/sell an array of activities/experiences to a diverse range of markets as novel and exclusive experiences to facilitate the growth of adventure holidays (Swarbrooke et al., 2003. To assist adventure tourism companies in achieving effective marketing strategies, the study’s objective is to identify significant sociopsychological profile differences among male and female adventure tourists in Pretoria, South Africa. Furthermore, to facilitate the comparison of adventure tourists’ profiles, an equal number of respondents were male (117 and female (117, which provided a 93.6% response rate. In comparison to female respondents, male respondents prefer winter as a season to participate in hard/high-risk adventure activities when they are with or without their family, and they participate in adventure activities for travelling and socialising purposes. Whereas, female respondents predominantly regard scuba-diving, abseiling, and helicopter flights as a hard/high-risk adventure activity, although these activities are generally regarded by the overall sample as being soft/low-risk adventure activities. Furthermore, even though females’ participation in adventure activities is sponsored, they did not participate or only participated in adventure activities once over the past year due to fear/risk and/or lack of skill. This study established that there is a need to further research adventure tourists’ profiles before it could be equally accepted and interpreted.

  4. Adventure sports and tourism at the beginning of the construction of Europe in the Pyrenees

    Directory of Open Access Journals (Sweden)

    André Suchet


    Full Text Available Organised in the spring of 1993 on the border between France and Spain, the Pyrenees Adventure Games (les Jeux Pyrénéens de l’Aventure or los Juegos Pirenaicos de la Aventura, brought together more than 1,000 athletes from 26 countries and were attended by 21,000 visitors. An alternative Olympics of adventure and outdoor sports patronised by the IOC, the events took place in the Aure Valley in France (Hautes-Pyrénées and in the Sobrarbe in Spain (Huesca province. This article analyses the governance of this international sports competition. More specifically, this case study will enable us to find out more about the conditions of organisation of a cross-border project in the early 1990s. What were the various political, social and cultural exchanges between the valleys in terms of sports and tourism in the Pyrenees? The results show that the French organisation and the Spanish organisation functioned side by side instead of working together on the field. This division in working enabled them to bypass the language problem. The cross-border dimension of these adventure Olympics in 1993 stemmed from pressure from the French regional planning agency, DATAR right from the beginning of the project, i.e. in October 1989, to be exact. This dimension made the 1993 Pyrenees Adventure Games a testimony to the new political Europe that was being built after 1989. This period was marked by the proactiveness of institutions, which far exceeded the motivations of the populations of the Union.Organisés au printemps 1993 sur la frontière entre la France et l’Espagne, les Jeux Pyrénéens de l’Aventure, ou los Juegos Pirenaicos de la Aventura, réunirent plus de 1 000 athlètes venus de 26 pays du monde sous les yeux de 21 000 visiteurs.

  1. The Andean Geotrail (1): A scientific adventure (United States)

    Sassier, C.; Galland, O.; Raufaste, C.; Mair, K.


    The role of Geosciences in our society is of primary importance. Its implications for humanity relate to major challenges such as climate change, managing energy resources, natural hazard mitigation, and water scarcity. Despite these issues being familiar to specialists, this is in general not the case for the public. In a world, where the impact of human activity is beginning to be seen on the environment, knowledge of the Earth and its history is paramount to make informed decisions that will influence our future. The necessity to educate the global population and raise awareness of Geosciences has led UNESCO to designate 2009 the International Year of the Planet Earth. In this context and with the label of the UNESCO, we organized and performed a popular science adventure that was followed in real time by both school children and many adults around the world. The Andean Geotrail consisted of a cycling expedition through a spectacular geological environment, the Andean Cordillera. During the nine month expedition, we cycled 8000 km and walked 400 km from Ushuaia in the Southern tip of Argentina to Nazca in Peru to encounter a rich variety of geological environments: active volcanoes, earthquakes, mineral and hydrocarbon deposits, and fantastic geological scenery. All this makes the Andes a great pedagogical natural laboratory. During the expedition, we visited spectacular geological localities that illustrate key Earth Science phenomena (such as mines and hydrocarbon deposits, erupting volcanoes and seismogenically active areas, and national parks) and discovered their implications for the local people. Along the way, we interviewed local geologists and scientists who helped us understand the geology of their areas. We gathered our own observations with those of the local specialists and published essays, articles and photographs on our website and blog (, Seventeen schools in France and Norway

  3. Pursuit of excellence: A forgotten quest?

    Directory of Open Access Journals (Sweden)

    Mark B Wertheimer


    Full Text Available The article explores the current orthodontic landscape with respect to the challenges that affect the pursuit of excellence in the specialty. These challenges include marketing by manufacturing companies, financial pressures, marketplace competition, attaining practice efficiency, new product introduction with limited supporting evidence, attributing greater importance to patient experience than the best approach to treatment, and lack of public education regarding their best interests. Home or DIY treatment, bypassing office visits and the practitioner, have also emerged as a concerning trend with the public not clearly understanding the detrimental consequences that may ensue. An over reliance on technology may override individualized treatment and further compromise treatment results.

  4. Contributions to Pursuit-Evasion Game Theory (United States)

    Oyler, Dave Wilson

    This dissertation studies adversarial conflicts among a group of agents moving in the plane, possibly among obstacles, where some agents are pursuers and others are evaders. The goal of the pursuers is to capture the evaders, where capture requires a pursuer to be either co-located with an evader, or in close proximity. The goal of the evaders is to avoid capture. These scenarios, where different groups compete to accomplish conflicting goals, are referred to as pursuit-evasion games, and the agents are called players. Games featuring one pursuer and one evader are analyzed using dominance, where a point in the plane is said to be dominated by a player if that player is able to reach the point before the opposing players, regardless of the opposing players' actions. Two generalizations of the Apollonius circle are provided. One solves games with environments containing obstacles, and the other provides an alternative solution method for the Homicidal Chauffeur game. Optimal pursuit and evasion strategies based on dominance are provided. One benefit of dominance analysis is that it extends to games with many players. Two foundational games are studied; one features multiple pursuers against a single evader, and the other features a single pursuer against multiple evaders. Both are solved using dominance through a reduction to single pursuer, single evader games. Another game featuring competing teams of pursuers is introduced, where an evader cooperates with friendly pursuers to rendezvous before being captured by adversaries. Next, the assumption of complete and perfect information is relaxed, and uncertainties in player speeds, player positions, obstacle locations, and cost functions are studied. The sensitivity of the dominance boundary to perturbations in parameters is provided, and probabilistic dominance is introduced. The effect of information is studied by comparing solutions of games with perfect information to games with uncertainty. Finally, a pursuit law

  5. Smooth pursuit eye movements and schizophrenia: literature review. (United States)

    Franco, J G; de Pablo, J; Gaviria, A M; Sepúlveda, E; Vilella, E


    To review the scientific literature about the relationship between impairment on smooth pursuit eye movements and schizophrenia. Narrative review that includes historical articles, reports about basic and clinical investigation, systematic reviews, and meta-analysis on the topic. Up to 80% of schizophrenic patients have impairment of smooth pursuit eye movements. Despite the diversity of test protocols, 65% of patients and controls are correctly classified by their overall performance during this pursuit. The smooth pursuit eye movements depend on the ability to anticipate the target's velocity and the visual feedback, as well as on learning and attention. The neuroanatomy implicated in smooth pursuit overlaps to some extent with certain frontal cortex zones associated with some clinical and neuropsychological characteristics of the schizophrenia, therefore some specific components of smooth pursuit anomalies could serve as biomarkers of the disease. Due to their sedative effect, antipsychotics have a deleterious effect on smooth pursuit eye movements, thus these movements cannot be used to evaluate the efficacy of the currently available treatments. Standardized evaluation of smooth pursuit eye movements on schizophrenia will allow to use specific aspects of that pursuit as biomarkers for the study of its genetics, psychopathology, or neuropsychology.

  10. Cultivating lived-body consciousness: Enhancing cognition and emotion through outdoor learning

    Directory of Open Access Journals (Sweden)

    Thorburn Malcolm


    Full Text Available Through using school-based outdoor learning as the research context, the paper analyses the connections between bodily experiences and the embodied mind. Recent theorizing in outdoor learning, in reflecting phenomenology and Deweyian influences, has teased out how the relationships between the self, others and nature (environment can be extended to include embodied experiences. This would, it is argued, add something extra to either the intrinsic pursuit of enjoying practical experiences or the instrumental quest for subject knowledge gains via cognitive- informed analytical cycles of action and reflection. While generally sympathetic to this critique, we consider there is a cognitive and emotional need for embodied experiences to demonstrate that they can be suitably contemplative as well. Through drawing upon Tiberius (2008 naturalist-informed theorizing, the paper reviews the part bodily experiences in outdoor learning can play in cultivating stable values and in developing reasoning practices that provide insights into how personal responsibility can be exercised in relation to how we live. Through referencing the Scottish policy context, the paper exemplifies how learning outdoors can flourish on the basis of a joint body-mind focus; where pupils review their relations with others and nature, as well as valuing times when they are absorbed in experiences which fully engage their personal interests, skills and capacities. To enhance the prospects of these learning gains occurring we provide a self-check set of questions for teachers to review to as part of appraisal of learning and teaching outdoors

  11. CF-Pursuit: A Pursuit Method with a Clothoid Fitting and a Fuzzy Controller for Autonomous Vehicles

    Directory of Open Access Journals (Sweden)

    Yunxiao Shan


    Full Text Available Simple and efficient geometric controllers, like Pure-Pursuit, have been widely used in various types of autonomous vehicles to solve tracking problems. In this paper, we have developed a new pursuit method, named CF-Pursuit, which has been based on Pure-Pursuit but with certain differences. In CF-Pursuit, in order to reduce fitting errors, we used a clothoid C1 curve to replace the circle employed in Pure-Pursuit. This improvement to the fitting method helps the Pursuit method to decrease tracking errors. As regards the selection of look-ahead distance, we employed a fuzzy system to directly consider the path's curvature. There are three input variables in this fuzzy system, 6mcurvature, 9mcurvature and 12mcurvature, calculated from the clothoid fit with the current position and the goal position on the defined path. A Sugeno fuzzy model was adapted to output a reasonable look-ahead distance using the experiences of human drivers as well as our own tests. Compared with some other geometric controllers, CF-Pursuit performs better in robustness, cross track errors and stability. The results from field tests have proven the CF-Pursuit is a practical and efficient geometric method for the path tracking problems of autonomous vehicles.

  12. How safe is adventure tourism in New Zealand? An exploratory analysis. (United States)

    Bentley, T; Page, S; Meyer, D; Chalmers, D; Laird, I


    The paper reports findings from a multidisciplinary programme of research, the major aims of which were to determine the nature and extent of the New Zealand adventure tourism injury problem. Analysis of hospital discharge and mortality data for a 15-year period identified adventure tourism-related activities as contributing to approximately 20% of overseas visitor injuries, and 22% of fatalities. Activities that commonly involve independent-unguided adventure tourism, notably mountaineering, skiing and tramping, contributed most to injury and fatality incidence. Horse riding and cycling activities were identified from hospital discharge data and adventure tourism operators' reported client injury-incidence, as the commercial adventure tourism activities most frequently involved in client injuries. Falls were the most common injury events, and a range of client, equipment, environmental and organisational risk factors were identified. Possible interventions to reduce injury risk among overseas and domestic adventure tourists are discussed.

  13. Robust Matching Pursuit Extreme Learning Machines

    Directory of Open Access Journals (Sweden)

    Zejian Yuan


    Full Text Available Extreme learning machine (ELM is a popular learning algorithm for single hidden layer feedforward networks (SLFNs. It was originally proposed with the inspiration from biological learning and has attracted massive attentions due to its adaptability to various tasks with a fast learning ability and efficient computation cost. As an effective sparse representation method, orthogonal matching pursuit (OMP method can be embedded into ELM to overcome the singularity problem and improve the stability. Usually OMP recovers a sparse vector by minimizing a least squares (LS loss, which is efficient for Gaussian distributed data, but may suffer performance deterioration in presence of non-Gaussian data. To address this problem, a robust matching pursuit method based on a novel kernel risk-sensitive loss (in short KRSLMP is first proposed in this paper. The KRSLMP is then applied to ELM to solve the sparse output weight vector, and the new method named the KRSLMP-ELM is developed for SLFN learning. Experimental results on synthetic and real-world data sets confirm the effectiveness and superiority of the proposed method.

  14. Narcissism and the Pursuit of Status. (United States)

    Zeigler-Hill, Virgil; Vrabel, Jennifer K; McCabe, Gillian A; Cosby, Cheryl A; Traeder, Caitlin K; Hobbs, Kelsey A; Southard, Ashton C


    The purpose of the present studies was to examine the connections that narcissistic admiration and narcissistic rivalry had with various aspects of status. Study 1 examined the associations that narcissism had with the motivation to seek status in a sample of 1,219 community members. Study 2 examined whether narcissism interacted with the status seeking motive to predict how individuals pursued status in a sample of 760 community members and college students. Study 3 used a daily diary approach to examine whether narcissism moderated the associations that daily perceptions of status and affiliation had with state self-esteem in 356 college students. Our results revealed that narcissistic admiration and narcissistic rivalry were somewhat similar in their desire for status but had divergent associations with other aspects of status (e.g., strategies employed to attain status, perceptions of status, reactions to perceived status). The results of the present studies suggest that narcissistic admiration is associated with an agentic orientation to the pursuit of status, whereas narcissistic rivalry is associated with an antagonistic orientation to the pursuit of status. Discussion focuses on the implications of these results for our understanding of the connections between narcissism and status. This article is protected by copyright.

    Smooth pursuit impairment is recognized clinically by the presence of saccadic tracking of a small object and quantified by reduction in pursuit gain, the ratio of smooth eye movement velocity to the velocity of a foveal target. Correlation of the site of brain lesions, identified by imaging or neuropathological examination, with defective smooth…

  17. Directional asymmetries in human smooth pursuit eye movements. (United States)

    Ke, Sally R; Lam, Jessica; Pai, Dinesh K; Spering, Miriam


    Humans make smooth pursuit eye movements to bring the image of a moving object onto the fovea. Although pursuit accuracy is critical to prevent motion blur, the eye often falls behind the target. Previous studies suggest that pursuit accuracy differs between motion directions. Here, we systematically assess asymmetries in smooth pursuit. In experiment 1, binocular eye movements were recorded while observers (n = 20) tracked a small spot of light moving along one of four cardinal or diagonal axes across a featureless background. We analyzed pursuit latency, acceleration, peak velocity, gain, and catch-up saccade latency, number, and amplitude. In experiment 2 (n = 22), we examined the effects of spatial location and constrained stimulus motion within the upper or lower visual field. Pursuit was significantly faster (higher acceleration, peak velocity, and gain) and smoother (fewer and later catch-up saccades) in response to downward versus upward motion in both the upper and the lower visual fields. Pursuit was also more accurate and smoother in response to horizontal versus vertical motion. CONCLUSIONS. Our study is the first to report a consistent up-down asymmetry in human adults, regardless of visual field. Our findings suggest that pursuit asymmetries are adaptive responses to the requirements of the visual context: preferred motion directions (horizontal and downward) are more critical to our survival than nonpreferred ones.

  18. Is ecotourism an alternative to adventure tourism in El Chaco?

    Directory of Open Access Journals (Sweden)

    Daniela Polanco


    Full Text Available El Chaco is one of the cantons has excelled in adventure tourism. However, since 2006 this activity has not broken and tourism has been separated from the local development. The objective of the present investigation is to find out the issues that affect the adventure tourism in El Chaco and to propose a new tourism product regarding the zone possibilities. In order to obtain the results, it has been developed a theoretical and methodological investigation focused in interviews and social cartography in Gonzalo Díaz de Pineda and in the cantonal head El Chaco. The main results denote the lack of organization, the high costs and the impacts generated by the construction of the Coca Codo Sinclair hydroelectric power plant. These results make visible the problems and support the suggestion of practicing ecotourism as a new choice of local development in the region.

    Full Text Available One of the most interesting aspects of J.R.R. Tolkien’s stories, especially The Lord of the Rings is the presentation of the multidimensional characters; therefore, the complexity of interpretations concerning their actions, motives, and aims will be manifested from the beginning of the story, until the end. Following the study of a mythic hero’s adventure, initiation, and psychological aspects, the present paper focuses on the investigation of Predestinate Call to Adventure. The researcher has benefited the theories of Joseph Campbell, presented in his renowned book The Hero with a Thousand Faces and the supplementary comments of Christopher Vogler. In fact, the researcher’s motivation for the work initiated in this regard is to improve the very few previous attempts studied by others, concerning Frodo Baggins’ role as the main and the most tragic hero of The Lord of the Rings.

    Directory of Open Access Journals (Sweden)



    Full Text Available This paper focuses on the reflection on the relationship between values and methodological principles of Outdoor Education and spatial and geographical education perspectives, especially in pre-school and primary school, which relates to the age between 3 and 10 years. Outdoor Education is an educational practice that is already rooted in the philosophical thought of the 16th and the 17th centuries, from John Locke to Jean-Jacques Rousseau, and in the pedagogical thought, in particular Friedrich Fröbel, and it has now a quite stable tradition in Northern Europe countries. In Italy, however, there are still few experiences and they usually do not have a systematic and structural modality, but rather a temporarily and experimentally outdoor organization. In the first part, this paper focuses on the reasons that justify a particular attention to educational paths that favour outdoors activities, providing also a definition of outdoor education and highlighting its values. It is also essential to understand that educational programs in open spaces, such as a forest or simply the schoolyard, surely offers the possibility to learn geographical situations. Therefore, the question that arises is how to finalize the best stimulus that the spatial location guarantees for the acquisition of knowledge, skills and abilities about space and geography.

  3. Adventure Learning: Theory and Implementation of Hybrid Learning (United States)

    Doering, A.


    Adventure Learning (AL), a hybrid distance education approach, provides students and teachers with the opportunity to learn about authentic curricular content areas while interacting with adventurers, students, and content experts at various locations throughout the world within an online learning environment (Doering, 2006). An AL curriculum and online environment provides collaborative community spaces where traditional hierarchical classroom roles are blurred and learning is transformed. AL has most recently become popular in K-12 classrooms nationally and internationally with millions of students participating online. However, in the literature, the term "adventure learning" many times gets confused with phrases such as "virtual fieldtrip" and activities where someone "exploring" is posting photos and text. This type of "adventure learning" is not "Adventure Learning" (AL), but merely a slideshow of their activities. The learning environment may not have any curricular and/or social goals, and if it does, the environment design many times does not support these objectives. AL, on the other hand, is designed so that both teachers and students understand that their online and curriculum activities are in synch and supportive of the curricular goals. In AL environments, there are no disparate activities as the design considers the educational, social, and technological affordances (Kirschner, Strijbos, Kreijns, & Beers, 2004); in other words, the artifacts of the learning environment encourage and support the instructional goals, social interactions, collaborative efforts, and ultimately learning. AL is grounded in two major theoretical approaches to learning - experiential and inquiry-based learning. As Kolb (1984) noted, in experiential learning, a learner creates meaning from direct experiences and reflections. Such is the goal of AL within the classroom. Additionally, AL affords learners a real-time authentic online learning experience concurrently as they

  5. Contextual effects on motion perception and smooth pursuit eye movements. (United States)

    Spering, Miriam; Gegenfurtner, Karl R


    Smooth pursuit eye movements are continuous, slow rotations of the eyes that allow us to follow the motion of a visual object of interest. These movements are closely related to sensory inputs from the visual motion processing system. To track a moving object in the natural environment, its motion first has to be segregated from the motion signals provided by surrounding stimuli. Here, we review experiments on the effect of the visual context on motion processing with a focus on the relationship between motion perception and smooth pursuit eye movements. While perception and pursuit are closely linked, we show that they can behave quite distinctly when required by the visual context.

  13. Risk Stratification for Athletes and Adventurers in High-Altitude Environments: Recommendations for Preparticipation Evaluation. (United States)

    Campbell, Aaron D; McIntosh, Scott E; Nyberg, Andy; Powell, Amy P; Schoene, Robert B; Hackett, Peter


    High-altitude athletes and adventurers face a number of environmental and medical risks. Clinicians often advise participants or guiding agencies before or during these experiences. Preparticipation evaluation (PPE) has the potential to reduce risk of high-altitude illnesses in athletes and adventurers. Specific conditions susceptible to high-altitude exacerbation also important to evaluate include cardiovascular and lung diseases. Recommendations by which to counsel individuals before participation in altitude sports and adventures are few and of limited focus. We reviewed the literature, collected expert opinion, and augmented principles of a traditional sport PPE to accommodate the high-altitude wilderness athlete/adventurer. We present our findings with specific recommendations on risk stratification during a PPE for the high-altitude athlete/adventurer. Copyright © 2015. Published by Elsevier Inc.

  1. Effects of contrast on smooth pursuit eye movements. (United States)

    Spering, Miriam; Kerzel, Dirk; Braun, Doris I; Hawken, Michael J; Gegenfurtner, Karl R


    It is well known that moving stimuli can appear to move more slowly when contrast is reduced (P. Thompson, 1982). Here we address the question whether changes in stimulus contrast also affect smooth pursuit eye movements. Subjects were asked to smoothly track a moving Gabor patch. Targets varied in velocity (1, 8, and 15 deg/s), spatial frequency (0.1, 1, 4, and 8 c/deg), and contrast, ranging from just below individual thresholds to maximum contrast. Results show that smooth pursuit eye velocity gain rose significantly with increasing contrast. Below a contrast level of two to three times threshold, pursuit gain, acceleration, latency, and positional accuracy were severely impaired. Therefore, the smooth pursuit motor response shows the same kind of slowing at low contrast that was demonstrated in previous studies on perception.

  3. Contextual effects on smooth-pursuit eye movements. (United States)

    Spering, Miriam; Gegenfurtner, Karl R


    Segregating a moving object from its visual context is particularly relevant for the control of smooth-pursuit eye movements. We examined the interaction between a moving object and a stationary or moving visual context to determine the role of the context motion signal in driving pursuit. Eye movements were recorded from human observers to a medium-contrast Gaussian dot that moved horizontally at constant velocity. A peripheral context consisted of two vertically oriented sinusoidal gratings, one above and one below the stimulus trajectory, that were either stationary or drifted into the same or opposite direction as that of the target at different velocities. We found that a stationary context impaired pursuit acceleration and velocity and prolonged pursuit latency. A drifting context enhanced pursuit performance, irrespective of its motion direction. This effect was modulated by context contrast and orientation. When a context was briefly perturbed to move faster or slower eye velocity changed accordingly, but only when the context was drifting along with the target. Perturbing a context into the direction orthogonal to target motion evoked a deviation of the eye opposite to the perturbation direction. We therefore provide evidence for the use of absolute and relative motion cues, or motion assimilation and motion contrast, for the control of smooth-pursuit eye movements.

  4. A medical perspective on the adventures of Sherlock Holmes. (United States)

    Reed, J


    The adventures of Sherlock Holmes, although primarily famous as stories of detection of crime, offer a considerable amount to interest the medical reader. There are many medical references in the stories, and the influence of Conan Doyle's medical background is clearly seen in the main characters. Aspects of the stories also reflect Conan Doyle's medical career, and also something of his attitude towards the profession. From Holmes's sayings and accounts of his methods, parallels can be drawn between Holmesian deduction and the diagnostic process. It is concluded, however, that deduction cannot be used as a direct paradigm since medical problems are rarely soluble through a process of logic alone.

  5. Outdoor radon variation in Romania

    International Nuclear Information System (INIS)

    Simion, Elena; Simion, Florin


    Full text: The results of a long-term survey (1992 - 2006) of the variations of outdoor radon concentrations in semi-natural location from Romania are reported in the present paper. Measurements, covering between two and four sessions of the day (morning, afternoon, evening and night), were performed on a daily bases by 37 Environmental Radioactivity Monitoring Stations from National Environmental Radioactivity Survey Network. The method used was based on indirect determination of outdoor radon from aerosol samples collected on glass micro-fibre filters by drawing the air through the filters. The sampling was performed in a fixed place at a height of 2 m above the ground surface. Total beta counting of aerosol samples collected was performed immediately and after 20 hours. Values recorded during the years of continuous measurement indicated the presence of several patterns in the long-term variation of outdoor radon concentration: diurnal, seasonal and annual variation. For diurnal variation, outdoor radon concentration shows a maximum values in the night (early hours) and minimum values by day (in the afternoon). On average, this maximum is a factor of 2 higher than the minimum. Late autumn - beginning of winter maximum and an early spring minimum are characteristic for seasonal patterns. In the long term a seasonal pattern was observed for diurnal variation, with an average diurnal maximum to minimum ratio of 1.33 in winter compared with 3.0 in the summer months. The variations of outdoor radon levels showed little correlation with the uranium concentration of the ground and were attributed to changes in soil moisture content. In dry seasons, because of the low precipitation, the soil was drying out in the summer allowing fractures to develop and radon to migrate easily through the ground. Depending on micro-climatic and geological conditions, outdoor radon average concentrations in different regions of Romania are from 1200 mBq/mc to 13065 mBq/mc. The smallest

  7. Cue-dependent memory-based smooth-pursuit in normal human subjects: importance of extra-retinal mechanisms for initial pursuit. (United States)

    Ito, Norie; Barnes, Graham R; Fukushima, Junko; Fukushima, Kikuro; Warabi, Tateo


    Using a cue-dependent memory-based smooth-pursuit task previously applied to monkeys, we examined the effects of visual motion-memory on smooth-pursuit eye movements in normal human subjects and compared the results with those of the trained monkeys. These results were also compared with those during simple ramp-pursuit that did not require visual motion-memory. During memory-based pursuit, all subjects exhibited virtually no errors in either pursuit-direction or go/no-go selection. Tracking eye movements of humans and monkeys were similar in the two tasks, but tracking eye movements were different between the two tasks; latencies of the pursuit and corrective saccades were prolonged, initial pursuit eye velocity and acceleration were lower, peak velocities were lower, and time to reach peak velocities lengthened during memory-based pursuit. These characteristics were similar to anticipatory pursuit initiated by extra-retinal components during the initial extinction task of Barnes and Collins (J Neurophysiol 100:1135-1146, 2008b). We suggest that the differences between the two tasks reflect differences between the contribution of extra-retinal and retinal components. This interpretation is supported by two further studies: (1) during popping out of the correct spot to enhance retinal image-motion inputs during memory-based pursuit, pursuit eye velocities approached those during simple ramp-pursuit, and (2) during initial blanking of spot motion during memory-based pursuit, pursuit components appeared in the correct direction. Our results showed the importance of extra-retinal mechanisms for initial pursuit during memory-based pursuit, which include priming effects and extra-retinal drive components. Comparison with monkey studies on neuronal responses and model analysis suggested possible pathways for the extra-retinal mechanisms.

  9. Receptive fields for smooth pursuit eye movements and motion perception. (United States)

    Debono, Kurt; Schütz, Alexander C; Spering, Miriam; Gegenfurtner, Karl R


    Humans use smooth pursuit eye movements to track moving objects of interest. In order to track an object accurately, motion signals from the target have to be integrated and segmented from motion signals in the visual context. Most studies on pursuit eye movements used small visual targets against a featureless background, disregarding the requirements of our natural visual environment. Here, we tested the ability of the pursuit and the perceptual system to integrate motion signals across larger areas of the visual field. Stimuli were random-dot kinematograms containing a horizontal motion signal, which was perturbed by a spatially localized, peripheral motion signal. Perturbations appeared in a gaze-contingent coordinate system and had a different direction than the main motion including a vertical component. We measured pursuit and perceptual direction discrimination decisions and found that both steady-state pursuit and perception were influenced most by perturbation angles close to that of the main motion signal and only in regions close to the center of gaze. The narrow direction bandwidth (26 angular degrees full width at half height) and small spatial extent (8 degrees of visual angle standard deviation) correspond closely to tuning parameters of neurons in the middle temporal area (MT).

  10. Reducing indoor residential exposures to outdoor pollutants

    Energy Technology Data Exchange (ETDEWEB)

    Sherman, Max H.; Matson, Nance E.


    The basic strategy for providing indoor air quality in residences is to dilute indoor sources with outdoor air. This strategy assumes that the outdoor air does not have pollutants at harmful levels or that the outdoor air is, at least, less polluted than the indoor air. When this is not the case, different strategies need to be employed to ensure adequate air quality in the indoor environment. These strategies include ventilation systems, filtration and other measures. These strategies can be used for several types of outdoor pollution, including smog, particulates and toxic air pollutants. This report reviews the impacts that typical outdoor air pollutants can have on the indoor environment and provides design and operational guidance for mitigating them. Poor quality air cannot be used for diluting indoor contaminants, but more generally it can become an indoor contaminant itself. This paper discusses strategies that use the building as protection against potentially hazardous outdoor pollutants, including widespread pollutants, accidental events, and potential attacks.

    Quercia, Daniele; Di Lorenzo, Giusy; Calabrese, Francesco; Ratti, Carlo


    Television and newspapers sit at the top of many agency marketing plans, while outdoor advertising stays at the bottom. The reason for this is that it’s difficult to account for who views a billboard, so there is no way of consistently determining the effectiveness of outdoor advertising. As a result, agencies do not consider the medium and allocate their money elsewhere. To change this situation, one needs to create new credible audience measurements for the outdoor marketing industry. He...

  14. GoNorth! - An Adventure Learning Case Study (United States)

    Porsild, M.; Doering, A.; Pregont, P.


    GoNorth! is an adventure learning series developed at the University of Minnesota in collaboration with NOMADS Online Expeditions. GoNorth! uses real-time experiences of dogsled expeditions on a multimedia saturated website at to motivate and engage millions of K-12 students and teachers. The program is free and research (Doering & Veletsianos, 2007) shows that it can be adopted by any teacher who signs up to use the program. It is currently utilized in 3400+ classrooms across the 50 US States and in 29 countries worldwide. Research (Doering & Veletsianos, 2007; 2008) notes that students working with GoNorth! are excited, motivated, and eager to engage with authentic tasks, solve real-world problems, collaborate with colleagues and experts, and initiate actions in their own community. Our team of educators, scientists and explorers circumnavigate the Arctic traveling by dog team to a new Arctic locale every year. Driven by an environmental question of particular relevance to the given Arctic region, each year a comprehensive natural and social science GoNorth! Curriculum & Activity Guide (450+ pages) is developed reflecting the expedition's current Arctic locale and its indigenous culture. The associated online learning environment delivers comprehensive resources about the region of travel, collaborative opportunities, live field updates and field research findings synched real-time to the curriculum. Field research relevant to understanding patterns of climate change and polar science is conducted with independent researchers featured as "Cool GoNorth! Scientists." Collaborations span from scientists at NASA and the United States Department of Agriculture to student observers in pan-Arctic communities as part of the NSF-supported initiative "What Is Climate Change to You?." This scientific research and fieldwork in turn coincides with the curriculum. The result is a community of learners on the Internet gaining knowledge from Arctic

  17. Multiagent Cooperative Learning Strategies for Pursuit-Evasion Games

    Directory of Open Access Journals (Sweden)

    Jong Yih Kuo


    Full Text Available This study examines the pursuit-evasion problem for coordinating multiple robotic pursuers to locate and track a nonadversarial mobile evader in a dynamic environment. Two kinds of pursuit strategies are proposed, one for agents that cooperate with each other and the other for agents that operate independently. This work further employs the probabilistic theory to analyze the uncertain state information about the pursuers and the evaders and uses case-based reasoning to equip agents with memories and learning abilities. According to the concepts of assimilation and accommodation, both positive-angle and bevel-angle strategies are developed to assist agents in adapting to their environment effectively. The case study analysis uses the Recursive Porous Agent Simulation Toolkit (REPAST to implement a multiagent system and demonstrates superior performance of the proposed approaches to the pursuit-evasion game.

  18. Hierarchical brain networks active in approach and avoidance goal pursuit. (United States)

    Spielberg, Jeffrey M; Heller, Wendy; Miller, Gregory A


    Effective approach/avoidance goal pursuit is critical for attaining long-term health and well-being. Research on the neural correlates of key goal-pursuit processes (e.g., motivation) has long been of interest, with lateralization in prefrontal cortex being a particularly fruitful target of investigation. However, this literature has often been limited by a lack of spatial specificity and has not delineated the precise aspects of approach/avoidance motivation involved. Additionally, the relationships among brain regions (i.e., network connectivity) vital to goal-pursuit remain largely unexplored. Specificity in location, process, and network relationship is vital for moving beyond gross characterizations of function and identifying the precise cortical mechanisms involved in motivation. The present paper integrates research using more spatially specific methodologies (e.g., functional magnetic resonance imaging) with the rich psychological literature on approach/avoidance to propose an integrative network model that takes advantage of the strengths of each of these literatures.

  19. Relative Effects of Forward and Backward Planning on Goal Pursuit. (United States)

    Park, Jooyoung; Lu, Fang-Chi; Hedgcock, William M


    Considerable research has shown that planning plays an important role in goal pursuit. But how does the way people plan affect goal pursuit? Research on this question is scarce. In the current research, we examined how planning the steps required for goal attainment in chronological order (i.e., forward planning) and reverse chronological order (i.e., backward planning) influences individuals' motivation for and perceptions of goal pursuit. Compared with forward planning, backward planning not only led to greater motivation, higher goal expectancy, and less time pressure but also resulted in better goal-relevant performance. We further demonstrated that this motivational effect occurred because backward planning allowed people to think of tasks required to reach their goals more clearly, especially when goals were complex to plan. These findings suggest that the way people plan matters just as much as whether or not they plan.

  1. FEFsem neuronal response during combined volitional and reflexive pursuit. (United States)

    Bakst, Leah; Fleuriet, Jérome; Mustari, Michael J


    Although much is known about volitional and reflexive smooth eye movements individually, much less is known about how they are coordinated. It is hypothesized that separate cortico-ponto-cerebellar loops subserve these different types of smooth eye movements. Specifically, the MT-MST-DLPN pathway is thought to be critical for ocular following eye movements, whereas the FEF-NRTP pathway is understood to be vital for volitional smooth pursuit. However, the role that these loops play in combined volitional and reflexive behavior is unknown. We used a large, textured background moving in conjunction with a small target spot to investigate the eye movements evoked by a combined volitional and reflexive pursuit task. We also assessed the activity of neurons in the smooth eye movement subregion of the frontal eye field (FEFsem). We hypothesized that the pursuit system would show less contribution from the volitional pathway in this task, owing to the increased involvement of the reflexive pathway. In accordance with this hypothesis, a majority of FEFsem neurons (63%) were less active during pursuit maintenance in a combined volitional and reflexive pursuit task than during purely volitional pursuit. Interestingly and surprisingly, the neuronal response to the addition of the large-field motion was highly correlated with the neuronal response to a target blink. This suggests that FEFsem neuronal responses to these different perturbations-whether the addition or subtraction of retinal input-may be related. We conjecture that these findings are due to changing weights of both the volitional and reflexive pathways, as well as retinal and extraretinal signals.

  2. Impaired smooth-pursuit in Parkinson's disease: normal cue-information memory, but dysfunction of extra-retinal mechanisms for pursuit preparation and execution. (United States)

    Fukushima, Kikuro; Ito, Norie; Barnes, Graham R; Onishi, Sachiyo; Kobayashi, Nobuyoshi; Takei, Hidetoshi; Olley, Peter M; Chiba, Susumu; Inoue, Kiyoharu; Warabi, Tateo


    While retinal image motion is the primary input for smooth-pursuit, its efficiency depends on cognitive processes including prediction. Reports are conflicting on impaired prediction during pursuit in Parkinson's disease. By separating two major components of prediction (image motion direction memory and movement preparation) using a memory-based pursuit task, and by comparing tracking eye movements with those during a simple ramp-pursuit task that did not require visual memory, we examined smooth-pursuit in 25 patients with Parkinson's disease and compared the results with 14 age-matched controls. In the memory-based pursuit task, cue 1 indicated visual motion direction, whereas cue 2 instructed the subjects to prepare to pursue or not to pursue. Based on the cue-information memory, subjects were asked to pursue the correct spot from two oppositely moving spots or not to pursue. In 24/25 patients, the cue-information memory was normal, but movement preparation and execution were impaired. Specifically, unlike controls, most of the patients (18/24 = 75%) lacked initial pursuit during the memory task and started tracking the correct spot by saccades. Conversely, during simple ramp-pursuit, most patients (83%) exhibited initial pursuit. Popping-out of the correct spot motion during memory-based pursuit was ineffective for enhancing initial pursuit. The results were similar irrespective of levodopa/dopamine agonist medication. Our results indicate that the extra-retinal mechanisms of most patients are dysfunctional in initiating memory-based (not simple ramp) pursuit. A dysfunctional pursuit loop between frontal eye fields (FEF) and basal ganglia may contribute to the impairment of extra-retinal mechanisms, resulting in deficient pursuit commands from the FEF to brainstem. © 2015 The Authors.

    We all played tag when we were kids. What most of us don't realize is that this simple chase game is in fact an application of pursuit theory, and that the same principles of games like tag, dodgeball, and hide-and-seek are also at play in military strategy, high-seas chases by the Coast Guard, and even romantic pursuits. In Chases and Escapes, Paul Nahin gives us the first complete history of this fascinating area of mathematics, from its classical analytical beginnings to the present day.

  5. Reward action in the initiation of smooth pursuit eye movements


    Joshua, Mati; Lisberger, Stephen G.


    Reward has a powerful influence on motor behavior. To probe how and where reward systems alter motor behavior, we studied smooth pursuit eye movements in monkeys trained to associate the color of a visual cue with the size of the reward to be issued at the end of the target motion. When the tracking task presented two different colored targets that moved orthogonally, monkeys biased the initiation of pursuit towards the direction of motion of the target that led to larger reward. The bias was...

  6. Uranium mines and French mining companies: a magnificent adventure

    International Nuclear Information System (INIS)

    Blanc, J.


    The French mining adventure still arouses enthusiasm. The search for uranium began in 1945 with the creation of the Cea (Atomic Energy Board) whose one mission was to supply the nascent French nuclear programme with the necessary materials. Prospecting works were then led throughout France, Madagascar, the Ivory Coast and the French equatorial Africa. More than 60 years later the only surviving actor of this quest for uranium has become the mining department of Areva Nuclear Cycle which is itself a sub-company of Areva. The author, who was an ancient high executive of Cogema draws a detailed history of the French uranium mining industry with with its ups and downs, by analysing the impact of the 2 oil crisis and of the decline of nuclear energy in the decade following the Chernobyl accident.

  8. To Capture Student Interest in Geosciences, Plan an Adventure (United States)

    Sassier, Caroline; Galland, Olivier; Mair, Karen


    It is dawn, -17°C, and 4700 meters above sea level, and two young scientists are alone in a tiny tent in the middle of the immense desert of the Bolivian Altiplano. Their bicycles and sleeping bags are coated with a thin layer of ice. Muscles aching, as they did yesterday and probably will tomorrow, they shrug off their sleepiness as the sunrise heats up their tent. After a simple breakfast, the researchers peek out and feast their eyes on a stunning view of high volcanic peaks and salt lakes. They are on the Andean Geotrail, a 9-month bike adventure through the Andes mountains, from Ushuaia in Argentinean Tierra del Fuego to Nazca, Peru (see Figure 1). Their goal is to share this spectacular geological setting with primary-, secondary- and high-school students.

    CERN Document Server

    DuBrul, Sascha Altman


    Part mad manifesto, part revolutionary love letter, part freight train adventure story — Maps to the Other Side is a self-reflective shattered mirror, a twist on the classic punk rock travel narrative that searches for authenticity and connection in the lives of strangers and the solidarity and limitations of underground community. Beginning at the edge of the internet age, a time when radical zine culture prefigured social networking sites, these timely writings paint an illuminated trail through a complex labyrinth of undocumented migrants, anarchist community organizers, brilliant visionary artists, revolutionary seed savers, punk rock historians, social justice farmers, radical mental health activists, and iconoclastic bridge builders. This book is a document of one person's odyssey to transform his experiences navigating the psychiatric system by building community in the face of adversity; a set of maps for how rebels and dreamers can survive and thrive in a crazy world.

  11. Stakeholders willingness to apply sustainable adventure tourism indicators: a case of Waterval Boven in South Africa

    NN Tshipala


    Full Text Available In South Africa and across the globe, the development of adventure tourism industry has resulted in a multitude of different types of activities, destinations, risks, impacts and unsustainable practices. The development of adventure tourism in many destinations has boosted many economies across rural communities and countries. The added benefits of developing adventure tourism in a sustainable manner include the promotion of responsible investment, infrastructure development and a host of other positive economic, social and environmental impacts. This study investigates the stakeholders will to utilise sustainable adventure tourism indicators from residents, tourists, business owners and government employees at Waterval Boven if made available. Descriptive statistics were presented; Cronbach Alpha and Chi-square tests were also applied. In general, the respondents perceived the indicators positively and felt they could assist in the sustainable development of adventure tourism. The study contributes towards the development of sustainable adventure tourism destinations that can make a significant contribution towards poverty alleviation by maximising social and economic benefits for locals, enhancing cultural heritage and reducing any negative impacts on the environment.

  12. Adventurous activities, embodiment and nature: spiritual, sensual and sustainable? Embodying environmental justice

    Directory of Open Access Journals (Sweden)

    Barbara Humberstone


    Full Text Available This paper examines research on adventurous physical activities in nature from the perspective of the sentient body. Drawing upon ethnographic and autoethnographic research, I examine what has been termed 'peak' happenings or 'flow' which many who practise adventurous activities claim to experience through their whole body when in the 'zone'. I consider the concept of 'edgework', voluntary risk-taking, and insightful mobile and social understanding of the relationships between body, emotions and the elements, where the adventurous activity is experienced and interpreted as oneness with nature or expressed as 'spiritual' not only in high but also low risk nature-based sport. I then consider if and in what ways these knowledges may bring about greater understanding and action in relation to social and environmental justice. I argue that adventurous activities/nature-based sport may provide processes and practices that are alternative or complementary to traditional sporting 'body techniques' or 'body pedagogics'. I suggest that modern embodied adventurous practices in nature challenge dominant narratives of body/mind separation and potentially provide a pedagogic process fostering kinetic empathy. Finally I draw attention to the paradox of (re-presenting sensorial experiences of sport in nature and ask for consideration on how we interconnect with the environment when we participate in adventureous nature-based sports.

  1. Radon parameters in outdoor air

    International Nuclear Information System (INIS)

    Porstendoerfer, J.; Zock, Ch.; Wendt, J.; Reineking, A.


    For dose estimation by inhalation of the short lived radon progeny in outdoor air, the equilibrium factor (F), the unattached fraction (f p ), and the activity size distribution of the radon progeny were measured. Besides the radon parameter the meteorological parameter like temperature, wind speed, and rainfall intensity were registered. The measurements were carried out continuously for several weeks to find out the variation with time (day/night) and for different weather conditions. The radon gas, the unattached and aerosol-attached radon progenies were measured with an monitor developed for continuous measurements in outdoor air with low activity concentrations. For the determination of the activity size distribution a low pressure online alpha cascade impactor was used. The measured values of the equilibrium factor varied between 0.5-0.8 depending on weather conditions and time of the day. For high pressure weather conditions a diurnal variation of the F-factor was obtained. A lower average value (F=0.25) was registered during rainy days. The obtained f p -values varied between 0.04 and 0.12. They were higher than expected. The measured activity size distribution of the radon progeny averaged over a measurement period of three weeks can be approximated by a sum of three log-normal distributions. The greatest activity fraction is adsorbed on aerosol particles in the accumulation size range (100-1000 nm) with activity median diameters and geometric standard deviation values between 250-450 nm and 1.5-3.0, respectively. The activity median diameter of this accumulation mode in outdoor air was significantly greater than in indoor air (150-250 nm). An influence of the weather conditions on the activity of the accumulation particles was not significant. In contrast to the results of measurements in houses a small but significant fraction of the radon progeny (average value: 2%) is attached on coarse particles (>1000 nm). This fraction varied between 0-10%. 20

  10. Multiagent pursuit-evasion games: Algorithms and experiments (United States)

    Kim, Hyounjin

    Deployment of intelligent agents has been made possible through advances in control software, microprocessors, sensor/actuator technology, communication technology, and artificial intelligence. Intelligent agents now play important roles in many applications where human operation is too dangerous or inefficient. There is little doubt that the world of the future will be filled with intelligent robotic agents employed to autonomously perform tasks, or embedded in systems all around us, extending our capabilities to perceive, reason and act, and replacing human efforts. There are numerous real-world applications in which a single autonomous agent is not suitable and multiple agents are required. However, after years of active research in multi-agent systems, current technology is still far from achieving many of these real-world applications. Here, we consider the problem of deploying a team of unmanned ground vehicles (UGV) and unmanned aerial vehicles (UAV) to pursue a second team of UGV evaders while concurrently building a map in an unknown environment. This pursuit-evasion game encompasses many of the challenging issues that arise in operations using intelligent multi-agent systems. We cast the problem in a probabilistic game theoretic framework and consider two computationally feasible pursuit policies: greedy and global-max. We also formulate this probabilistic pursuit-evasion game as a partially observable Markov decision process and employ a policy search algorithm to obtain a good pursuit policy from a restricted class of policies. The estimated value of this policy is guaranteed to be uniformly close to the optimal value in the given policy class under mild conditions. To implement this scenario on real UAVs and UGVs, we propose a distributed hierarchical hybrid system architecture which emphasizes the autonomy of each agent yet allows for coordinated team efforts. We then describe our implementation on a fleet of UGVs and UAVs, detailing components such

  12. The home electronic media environment and parental safety concerns: relationships with outdoor time after school and over the weekend among 9-11 year old children. (United States)

    Wilkie, Hannah J; Standage, Martyn; Gillison, Fiona B; Cumming, Sean P; Katzmarzyk, Peter T


    Time spent outdoors is associated with higher physical activity levels among children, yet it may be threatened by parental safety concerns and the attraction of indoor sedentary pursuits. The purpose of this study was to explore the relationships between these factors and outdoor time during children's discretionary periods (i.e., after school and over the weekend). Data from 462 children aged 9-11 years old were analysed using generalised linear mixed models. The odds of spending > 1 h outdoors after school, and > 2 h outdoors on a weekend were computed, according to demographic variables, screen-based behaviours, media access, and parental safety concerns. Interactions with sex and socioeconomic status (SES) were explored. Boys, low SES participants, and children who played on their computer for  1 h outside after school than girls, high SES children and those playing on a computer for ≥2 h, respectively. Counterintuitive results were found for access to media devices and crime-related safety concerns as both of these were positively associated with time spent outdoors after school. A significant interaction for traffic-related concerns*sex was found; higher road safety concerns were associated with lower odds of outdoor time after school in boys only. Age was associated with weekend outdoor time, which interacted with sex and SES; older children were more likely to spend > 2 h outside on weekends but this was only significant among girls and high SES participants. Our results suggest that specific groups of children are less likely to spend their free time outside, and it would seem that only prolonged recreational computer use has a negative association with children's outdoor time after school. Further research is needed to explore potential underlying mechanisms, and parental safety concerns in more detail.

  15. The natural-geographical basics for the development of the adventure tourism in Serbia

    Directory of Open Access Journals (Sweden)

    Spalević Aleksandra


    Full Text Available Adventure tourism represents traveling motivated by the wish to be in the nature. It includes both physical and cultural interaction between the nature and a tourist. The concept of “adventure” includes the wish of a guest for unusual activities and experience. This is also followed by excitement. The natural and tourist potentials of Serbia are analyzed in this work. The types of adventure tourism, for which there are favorable conditions in our country, are sorted out. Among different adventure activities the most important are: hiking, speleo tourism, rafting, cannoning, paragliding and mountain biking. Nevertheless, due to many problems this branch of tourism is undeveloped. In the analysis of the tourist space of Serbia, the beginning point is the mountain documents from the section about the development of tourism. In accordance with them and based on natural and anthropogenic resources and the potentials of Serbia, the possible ways of development of adventure tourism in Serbia are defined. The aim of this work is to draw attention to adventure tourism of Serbia and to point out the possibilities of its development based on the characteristics of the natural values. It also aims to suggest the potential areas-centers of development of this tourist branch.

    Within the realm of education, seldom does an innovative program become available with the potential to change an educator`s teaching methodology. Adventures in Supercomputing (AiS), sponsored by the U.S. Department of Energy (DOE), is such a program. It is a program for high school teachers that changes the teacher paradigm from a teacher-directed approach of teaching to a student-centered approach. {open_quotes}A student-centered classroom offers better opportunities for development of internal motivation, planning skills, goal setting and perseverance than does the traditional teacher-directed mode{close_quotes}. Not only is the process of teaching changed, but the cross-curricula integration within the AiS materials is remarkable. Written from a teacher`s perspective, this paper will describe the AiS program and its effects on teachers and students, primarily at Wartburg Central High School, in Wartburg, Tennessee. The AiS program in Tennessee is sponsored by Oak Ridge National Laboratory (ORNL).

The aim of this book is to present the stakes of this challenge, to better outline the difficulties that have been encountered all along its development in order to better understand the complexness of such a development. After an overview of the successive advances of atomic and nuclear physics since more than a century, the book describes the genesis of nuclear energy, its industrial developments and its still wide open perspectives. The conclusions makes a status of the advantages and risks linked with this energy source. The book contains also the testimonies of two French nuclear actors: P. Benoist and S. David. The forewords by H. Langevin, daughter of F. and I. Joliot-Curie, stresses on the past and future role of nuclear energy in the live synergy between research and industry. (J.S.)

  18. Pre-Participation Medical Evaluation for Adventure and Wilderness Watersports. (United States)

    Nathanson, Andrew T; Young, Justin Mark J; Young, Craig


    A request for a preparticipation medical evaluation for wilderness watersports may be made by guiding agencies, instructional camps, or by patients presenting for an annual visit. Although guidelines have been published regarding preparticipation physical evaluation for traditional competitive high school and collegiate sports, little has been written about medical evaluations for those wishing to engage in wilderness and adventure watersports. in this article, we offer guidance based on literature review and expert opinion. Watersports are among the most common recreational activities in the United states and are generally safe. Drowning, however, is a significant risk, particularly in small, self-propelled craft, and among children. Medical counseling before participation in watersports should include screening for medical conditions which may impair swimming ability, including a history of seizures, heart disease, and lung disease. Physicians should also promote preventive health measures such as use of lifejackets and sun protection, as well as alcohol avoidance. Swim testing tailored to specific activities should be strongly considered for children and those with questionable swimming ability. Copyright © 2015. Published by Elsevier Inc.

  19. "My petticoat encumbrances"; the 'female adventurer' and the north

    Directory of Open Access Journals (Sweden)

    Kathryn Walchester


    Full Text Available Focussing on the northern travelogues of two women travellers from the late nineteenth century, Ethel Brilliana Tweedie’s A Winter Jaunt to Norway: with Accounts of Nansen, Ibsen, Bjornson, Brandes, and Many Others and Polar Gleams; an Account of a Voyage on the Yacht ‘Blencathra’ by Helen Peel, this article suggests that rather than presenting a polarized gendered perspective of Arctic travel, in their writing Peel and Tweedie negotiate between masculine and feminine-coded associations in order to legitimate and popularize their travels, whilst remaining within the conventions of Victorian femininity.  Of the strategies for ensuring the apparent propriety of their text, the references to clothing are highly significant on several levels. Not only could Peel and Tweedie show their adherence (or not to conventional feminine dress through their descriptions of their clothing, they could also illustrate their relationship to other travellers and the Norwegians they encountered. Thus the ‘petticoat encumbrances’ have a double function in the text. Symbolic of Victorian conventions of femininity and their limitations on women, the adherence to sartorial norms at least indicated to readers and critics of the woman traveller’s compliance with gender conventions. This achieved, the woman travel writer had more scope to embark on her remarkable journey and to write about its potential adventures with enthusiasm as a ‘female adventurer’ and still remain within the acceptable boundaries of late-Victorian femininity.

  20. 'The adventure': Charles-Ferdinand Ramuz's extraordinary stroke diary. (United States)

    Bogousslavsky, J


    The famous Swiss writer Charles-Ferdinand Ramuz suffered a stroke at 65 years, which he called 'the adventure' or 'the accident'. He developed language disturbances suggesting crossed aphasia in a right hander with left hemiparesis. This uncommon pattern allowed him to continue to write his diary and to report his disturbances, with a unique depth and precision, especially for cognitive-emotional changes. Language and motor dysfunction recovered within a few weeks, but Ramuz complained of persisting emotional flattening alternating with irritability, fatigue, depression, anxiety, and concentration difficulty, which gave him the feeling to have become another person and to be inhabited by a stranger, whom he compared with devils. Ramuz fought several months to resume his literary activity, having the impression to have lost inspiration and creativity. However, the novels he wrote less than 6 months after stroke show no stylistic changes and have been found to be of the same quality as his previous production. Ramuz even 'used' his stroke experience in his work, in particular in a novel depicting an old man who has a stroke and dies of it. Ramuz's diary, with his own daily description of stroke features and consequences during acute and recovery phases, is a unique document in a writer of his importance, and provides invaluable information on subjective emotional and cognitive experience of stroke.

  1. Adventures of Geo: Using comics as a learning tool (United States)

    Lee, K. K. M.; Wallenta, A.


    Illustrations are a good way to visualize what is not readily seen. To take this medium a step further, we use illustrations in the form of comics as a way to teach Earth science concepts. The comic book format lends itself to engaging reading for young and old alike and has been used recently by the American Physical Society (APS) and by NASA as an outreach teaching tool. Due to their sequential nature, comic books make it easy for readers to follow a story and grasp concepts that are covered. The limited text in each panel can also help those where reading is a challenge or for those who become nervous and/or discouraged with long text passages. The illustrations also add visual clues that can aid in understanding the concepts being laid out. In the second installment of "Adventures of Geo," we use the comic book format to introduce the Moon, its formation, evolution, orbit and its interplay with Earth. The exploration of such faraway places is readily disseminated to the public through such a graphical approach. The comic books are aimed at middle school students in the New Haven Public Schools (NHPS) where Earth Science topics are covered in the curriculum.

  4. Landmine detection using two-tapped joint orthogonal matching pursuits (United States)

    Goldberg, Sean; Glenn, Taylor; Wilson, Joseph N.; Gader, Paul D.


    Joint Orthogonal Matching Pursuits (JOMP) is used here in the context of landmine detection using data obtained from an electromagnetic induction (EMI) sensor. The response from an object containing metal can be decomposed into a discrete spectrum of relaxation frequencies (DSRF) from which we construct a dictionary. A greedy iterative algorithm is proposed for computing successive residuals of a signal by subtracting away the highest matching dictionary element at each step. The nal condence of a particular signal is a combination of the reciprocal of this residual and the mean of the complex component. A two-tap approach comparing signals on opposite sides of the geometric location of the sensor is examined and found to produce better classication. It is found that using only a single pursuit does a comparable job, reducing complexity and allowing for real-time implementation in automated target recognition systems. JOMP is particularly highlighted in comparison with a previous EMI detection algorithm known as String Match.

  10. Hierarchical brain networks active in approach and avoidance goal pursuit

    Directory of Open Access Journals (Sweden)

    Jeffrey Martin Spielberg


    Full Text Available Effective approach/avoidance goal pursuit is critical for attaining long-term health and well-being. Research on the neural correlates of key goal pursuit processes (e.g., motivation has long been of interest, with lateralization in prefrontal cortex being a particularly fruitful target of investigation. However, this literature has often been limited by a lack of spatial specificity and has not delineated the precise aspects of approach/avoidance motivation involved. Additionally, the relationships among brain regions (i.e., network connectivity vital to goal pursuit remain largely unexplored. Specificity in location, process, and network relationship is vital for moving beyond gross characterizations of function and identifying the precise cortical mechanisms involved in motivation. The present paper integrates research using more spatially specific methodologies (e.g., functional magnetic resonance imaging with the rich psychological literature on approach/avoidance to propose an integrative network model that takes advantage of the strengths of each of these literatures.

  11. Designing and Building of 3D Adventure Game “Tetuko: Childhood of Ghatotkacha” Using Kinect

    Directory of Open Access Journals (Sweden)

    Achmad Basuki


    Full Text Available Nowadays, the young people are not interested in the local culture as a “wayang” puppet. This condition threatens the extinction of some of the local culture that should be a mainstay of the industry entering an era of creative industries. On the other hand, theyare more interested in playing computer games as changing of people's lifestyles. It becomes our basic idea to produce a game as a creative product. The genre of this game is fighting-adventure. This game depictures a story of fighting between the baby Tetuko and giant Kala Pracona. The game uses Kinect and 3D platform technology to attract more players to feel their adventures. With Kinect technology, the player can control the character with his gesture. Thus, this game will increase the awareness of young people about the culture of Wayang. Keywords : 3D game, kinect,adventure, local culture, creative industry.

  12. Integration of professional judgement and decision-making in high-level adventure sports coaching practice. (United States)

    Collins, Loel; Collins, Dave


    This study examined the integration of professional judgement and decision-making processes in adventure sports coaching. The study utilised a thematic analysis approach to investigate the decision-making practices of a sample of high-level adventure sports coaches over a series of sessions. Results revealed that, in order to make judgements and decisions in practice, expert coaches employ a range of practical and pedagogic management strategies to create and opportunistically use time for decision-making. These approaches include span of control and time management strategies to facilitate the decision-making process regarding risk management, venue selection, aims, objectives, session content, and differentiation of the coaching process. The implication for coaches, coach education, and accreditation is the recognition and training of the approaches that "create time" for the judgements in practice, namely "creating space to think". The paper concludes by offering a template for a more expertise-focused progression in adventure sports coaching.

  15. Understanding Action and Adventure Sports Participation-An Ecological Dynamics Perspective. (United States)

    Immonen, Tuomas; Brymer, Eric; Orth, Dominic; Davids, Keith; Feletti, Francesco; Liukkonen, Jarmo; Jaakkola, Timo


    Previous research has considered action and adventure sports using a variety of associated terms and definitions which has led to confusing discourse and contradictory research findings. Traditional narratives have typically considered participation exclusively as the pastime of young people with abnormal characteristics or personalities having unhealthy and pathological tendencies to take risks because of the need for thrill, excitement or an adrenaline 'rush'. Conversely, recent research has linked even the most extreme forms of action and adventure sports to positive physical and psychological health and well-being outcomes. Here, we argue that traditional frameworks have led to definitions, which, as currently used by researchers, ignore key elements constituting the essential merit of these sports. In this paper, we suggest that this lack of conceptual clarity in understanding cognitions, perception and action in action and adventure sports requires a comprehensive explanatory framework, ecological dynamics which considers person-environment interactions from a multidisciplinary perspective. Action and adventure sports can be fundamentally conceptualized as activities which flourish through creative exploration of novel movement experiences, continuously expanding and evolving beyond predetermined environmental, physical, psychological or sociocultural boundaries. The outcome is the emergence of a rich variety of participation styles and philosophical differences within and across activities. The purpose of this paper is twofold: (a) to point out some limitations of existing research on action and adventure sports; (b) based on key ideas from emerging research and an ecological dynamics approach, to propose a holistic multidisciplinary model for defining and understanding action and adventure sports that may better guide future research and practical implications.

  16. The sweetness of successful goal pursuit: Approach-motivated pregoal states enhance the reward positivity during goal pursuit. (United States)

    Threadgill, A Hunter; Gable, Philip A


    Traditionally, the reward positivity (RewP) is thought to index a binary performance monitoring system sensitive to approach motivation. However, recent theoretical models have argued that feedback processing extends beyond simple "good" vs. "bad" associations, such that performance monitoring incorporates the complex, multi-step sequence of behaviors often necessary to attain rewards. The present study sought to go beyond simple stimulus-response paradigms to examine how approach-motivated states occurring in multi-step goal pursuit impacts the RewP. Additionally, outcome frequency was varied to examine how the P3, a neural marker of expectancy, influences the RewP. Using a modified monetary incentive delay paradigm, participants played a reaction time game where multiple correct responses were required to attain a reward. Additionally, each trial had the potential for a reward (approach-motivated state) or no reward (neutral state). Results revealed that RewP amplitudes were larger after reward trial win feedback than after reward trial no-win feedback across multiple stages of goal pursuit. Additionally, after for controlling outcome frequency via the P3, RewP amplitudes were larger in reward trials than in neutral trials across incremental stages of goal pursuit. The RewP appears to be sensitive to feedback indicating successfully completing sub-goals during pursuit of a goal, even when no immediate reward is given. Approach motivation enhances performance monitoring when multiple steps are needed to attain a desired outcome, which may increase the likelihood of goal acquisition and attainment.

  18. Role of retinal slip in the prediction of target motion during smooth and saccadic pursuit. (United States)

    de Brouwer, S; Missal, M; Lefèvre, P


    Visual tracking of moving targets requires the combination of smooth pursuit eye movements with catch-up saccades. In primates, catch-up saccades usually take place only during pursuit initiation because pursuit gain is close to unity. This contrasts with the lower and more variable gain of smooth pursuit in cats, where smooth eye movements are intermingled with catch-up saccades during steady-state pursuit. In this paper, we studied in detail the role of retinal slip in the prediction of target motion during smooth and saccadic pursuit in the cat. We found that the typical pattern of pursuit in the cat was a combination of smooth eye movements with saccades. During smooth pursuit initiation, there was a correlation between peak eye acceleration and target velocity. During pursuit maintenance, eye velocity oscillated at approximately 3 Hz around a steady-state value. The average gain of smooth pursuit was approximately 0.5. Trained cats were able to continue pursuing in the absence of a visible target, suggesting a role of the prediction of future target motion in this species. The analysis of catch-up saccades showed that the smooth-pursuit motor command is added to the saccadic command during catch-up saccades and that both position error and retinal slip are taken into account in their programming. The influence of retinal slip on catch-up saccades showed that prediction about future target motion is used in the programming of catch-up saccades. Altogether, these results suggest that pursuit systems in primates and cats are qualitatively similar, with a lower average gain in the cat and that prediction affects both saccades and smooth eye movements during pursuit.

  19. Discrimination of curvature from motion during smooth pursuit eye movements and fixation. (United States)

    Ross, Nicholas M; Goettker, Alexander; Schütz, Alexander C; Braun, Doris I; Gegenfurtner, Karl R


    Smooth pursuit and motion perception have mainly been investigated with stimuli moving along linear trajectories. Here we studied the quality of pursuit movements to curved motion trajectories in human observers and examined whether the pursuit responses would be sensitive enough to discriminate various degrees of curvature. In a two-interval forced-choice task subjects pursued a Gaussian blob moving along a curved trajectory and then indicated in which interval the curve was flatter. We also measured discrimination thresholds for the same curvatures during fixation. Motion curvature had some specific effects on smooth pursuit properties: trajectories with larger amounts of curvature elicited lower open-loop acceleration, lower pursuit gain, and larger catch-up saccades compared with less curved trajectories. Initially, target motion curvatures were underestimated; however, ∼300 ms after pursuit onset pursuit responses closely matched the actual curved trajectory. We calculated perceptual thresholds for curvature discrimination, which were on the order of 1.5 degrees of visual angle (°) for a 7.9° curvature standard. Oculometric sensitivity to curvature discrimination based on the whole pursuit trajectory was quite similar to perceptual performance. Oculometric thresholds based on smaller time windows were higher. Thus smooth pursuit can quite accurately follow moving targets with curved trajectories, but temporal integration over longer periods is necessary to reach perceptual thresholds for curvature discrimination. NEW & NOTEWORTHY Even though motion trajectories in the real world are frequently curved, most studies of smooth pursuit and motion perception have investigated linear motion. We show that pursuit initially underestimates the curvature of target motion and is able to reproduce the target curvature ∼300 ms after pursuit onset. Temporal integration of target motion over longer periods is necessary for pursuit to reach the level of precision found

  20. Engineering thermal engine rocket adventurer for space nuclear application

    International Nuclear Information System (INIS)

    Nam, Seung H.; Suh, Kune Y.; Kang, Seong G.


    The conceptual design for the first-of-a-kind engineering of Thermal Engine Rocket Adventure (TERA) is described. TERA comprising the Battery Omnibus Reactor Integral System (BORIS) as the heat resource and the Space Propulsion Reactor Integral System (SPRIS) as the propulsion system, is one of the advanced Nuclear Thermal Rocket (NTR) engine utilizing hydrogen (H 2 ) propellant being developed at present time. BORIS in this application is an open cycle high temperature gas cooled reactor that has eighteen fuel elements for propulsion and one fuel element for electricity generation and propellant pumping. Each fuel element for propulsion has its own small nozzle. The nineteen fuel elements are arranged into hexagonal prism shape in the core and surrounded by outer Be reflector. The TERA maximum power is 1,000 MW th , specific impulse 1,000 s, thrust 250,000 N, and the total mass is 550 kg including the reactor, turbo pump and auxiliaries. Each fuel element comprises the fuel assembly, moderators, pressure tube and small nozzle. The TERA fuel assembly is fabricated of 93% enriched 1.5 mm (U, Zr, Nb)C wafers in 25.3% voided Square Lattice Honeycomb (SLHC). The H 2 propellant passes through these flow channels. This study is concerned with thermohydrodynamic analysis of the fuel element for propulsion with hypothetical axial power distribution because nuclear analysis of TERA has not been performed yet. As a result, when the power distribution of INSPI's M-SLHC is applied to the fuel assembly, the local heat concentration of fuel is more serious and the pressure of the initial inlet H 2 is higher than those of constant average power distribution applied. This means the fuel assembly geometry of 1.5 mm fuel wafers and 25.3% voided SLHC needs to be changed in order to reduce thermal and mechanical shocks. (author)

  1. Outdoor smoking behaviour and support for outdoor smoking restrictions before and after France's national smoking ban. (United States)

    Kennedy, Ryan David; Behm, Ilan; Craig, Lorraine; Thompson, Mary E; Fong, Geoffrey T; Guignard, Romain; Beck, Francois


    On January 1, 2008, the French government implemented a national ban on indoor smoking in hospitality venues. Survey results indicate the indoor ban has been successful at dramatically reducing indoor smoking; however, there are reports of an increased number of outdoor hospitality spaces (patios) where smoking can take place. This study sought to understand if the indoor ban simply moved smoking to the outdoors, and to assess levels of support for smoking restrictions in outdoor hospitality settings after the smoke-free law. Telephone interviews were conducted among 1067 adult smokers before and after the 2008 indoor ban as part of the International Tobacco Control (ITC) France Survey. Among other topics, this survey measures how the smoking ban has influenced smoking behaviour relevant to outdoor sections of hospitality venues. In addition, 414 non-smoking adults and 164 respondents who had quit smoking between waves were also asked about support for outdoor smoking restrictions. Reported smoking outdoors at cafés/pubs/bars increased from 33.6% of smokers at Wave 1 to 75.9% at Wave 2. At restaurants, smoking outdoors increased from 28.9% to 59.0%. There was also an increase in reported non-smoking for both visits to cafés/pubs/bars, and restaurants from 13.4% to 24.7%, and 30.4% to 40.8% respectively. The majority of smokers (74.5%), non-smokers (89.4%) and quitters (74.0%) support a partial or complete ban on smoking in outdoor areas of restaurants. The indoor smoking ban moved smoking to outdoor spaces; however, the ban is also associated with increased non-smoking behaviour. The majority of respondents support outdoor smoking restrictions in patio environments.

  2. Predicting 2D target velocity cannot help 2D motion integration for smooth pursuit initiation. (United States)

    Montagnini, Anna; Spering, Miriam; Masson, Guillaume S


    Smooth pursuit eye movements reflect the temporal dynamics of bidimensional (2D) visual motion integration. When tracking a single, tilted line, initial pursuit direction is biased toward unidimensional (1D) edge motion signals, which are orthogonal to the line orientation. Over 200 ms, tracking direction is slowly corrected to finally match the 2D object motion during steady-state pursuit. We now show that repetition of line orientation and/or motion direction does not eliminate the transient tracking direction error nor change the time course of pursuit correction. Nonetheless, multiple successive presentations of a single orientation/direction condition elicit robust anticipatory pursuit eye movements that always go in the 2D object motion direction not the 1D edge motion direction. These results demonstrate that predictive signals about target motion cannot be used for an efficient integration of ambiguous velocity signals at pursuit initiation.

  15. Thrill and adventure seeking in risky driving at work: The moderating role of safety climate. (United States)

    Wishart, Darren; Somoray, Klaire; Evenhuis, Amanda


    Introduction Within many industrialized countries, the leading cause of worker fatalities and serious injuries can be attributed to road trauma. In non-occupational research, high levels of sensation seeking personality, and specifically thrill and adventure seeking, have been associated with risky driving behaviors. In work driving literature, high organizational safety climate has been associated with reduced risky driving in work drivers. However, the extent that factors such as safety climate and thrill seeking interact in regard to work driving safety remains unclear, and the current research examined this interaction. Methods A total of 1,011 work drivers from four organizations participated in the research. Surveys were distributed online and hardcopies were sent via mail. The survey included measures of thrill and adventure seeking, safety climate and work-related driving behaviors, as well as questions relating to participant demographics and information about their work driving. Results The results demonstrated that safety climate significantly moderated the effect of thrill and adventure seeking trait on driving errors, driving violations, and driving while fatigued. Conclusion These results suggest that the development of a strong safety climate has the potential to improve work driving safety outcomes by reducing the impact of particular personality traits such as thrill seeking within an organizational context. Practical application To improve work driving safety, organizations and management need to develop strategies to encourage and foster positive work driving safety climate, particularly within work settings that may attract thrill and adventure seeking employees.

  18. Vestibular-related frontal cortical areas and their roles in smooth-pursuit eye movements: representation of neck velocity, neck-vestibular interactions and memory-based smooth-pursuit

    Directory of Open Access Journals (Sweden)

    Kikuro eFukushima


    Full Text Available Smooth-pursuit eye movements are voluntary responses to small slow-moving objects in the fronto-parallel plane. They evolved in primates, who possess high-acuity foveae, to ensure clear vision about the moving target. The primate frontal cortex contains two smooth-pursuit related areas; the caudal part of the frontal eye fields (FEF and the supplementary eye fields (SEF. Both areas receive vestibular inputs. We review functional differences between the two areas in smooth-pursuit. Most FEF pursuit neurons signal pursuit parameters such as eye velocity and gaze-velocity, and are involved in cancelling the vestibulo-ocular reflex by linear addition of vestibular and smooth-pursuit responses. In contrast, gaze-velocity signals are rarely represented in the SEF. Most FEF pursuit neurons receive neck velocity inputs, while discharge modulation during pursuit and trunk-on-head rotation adds linearly. Linear addition also occurs between neck velocity responses and vestibular responses during head-on-trunk rotation in a task-dependent manner. During cross-axis pursuit-vestibular interactions, vestibular signals effectively initiate predictive pursuit eye movements. Most FEF pursuit neurons discharge during the interaction training after the onset of pursuit eye velocity, making their involvement unlikely in the initial stages of generating predictive pursuit. Comparison of representative signals in the two areas and the results of chemical inactivation during a memory-based smooth-pursuit task indicate they have different roles; the SEF plans smooth-pursuit including working memory of motion-direction, whereas the caudal FEF generates motor commands for pursuit eye movements. Patients with idiopathic Parkinson’s disease were asked to perform this task, since impaired smooth-pursuit and visual working memory deficit during cognitive tasks have been reported in most patients. Preliminary results suggested specific roles of the basal ganglia in memory

  19. The Pursuit of Chronically Reliable Neural Interfaces: A Materials Perspective. (United States)

    Guo, Liang


    Brain-computer interfaces represent one of the most astonishing technologies in our era. However, the grand challenge of chronic instability and limited throughput of the electrode-tissue interface has significantly hindered the further development and ultimate deployment of such exciting technologies. A multidisciplinary research workforce has been called upon to respond to this engineering need. In this paper, I briefly review this multidisciplinary pursuit of chronically reliable neural interfaces from a materials perspective by analyzing the problem, abstracting the engineering principles, and summarizing the corresponding engineering strategies. I further draw my future perspectives by extending the proposed engineering principles.

  20. Fixed Duration Pursuit-Evasion Differential Game with Integral Constraints

    International Nuclear Information System (INIS)

    Ibragimov G I; Kuchkarov A Sh


    We investigate a pursuit-evasion differential game of countably many pursuers and one evader. Integral constraints are imposed on control functions of the players. Duration of the game is fixed and the payoff of the game is infimum of the distances between the evader and pursuers when the game is completed. Purpose of the pursuers is to minimize the payoff and that of the evader is to maximize it. Optimal strategies of the players are constructed, and the value of the game is found. It should be noted that energy resource of any pursuer may be less than that of the evader.

  2. The pursuit of happiness: time, money, and social connection. (United States)

    Mogilner, Cassie


    Does thinking about time, rather than money, influence how effectively individuals pursue personal happiness? Laboratory and field experiments revealed that implicitly activating the construct of time motivates individuals to spend more time with friends and family and less time working-behaviors that are associated with greater happiness. In contrast, implicitly activating money motivates individuals to work more and socialize less, which (although productive) does not increase happiness. Implications for the relative roles of time versus money in the pursuit of happiness are discussed.

  3. Outdoor ultraviolet exposure of children and adolescents

    International Nuclear Information System (INIS)

    Diffey, B.L.; Gibson, C.J.


    The weekday and weekend outdoor ultraviolet exposure of young people from primary and secondary schools in three geographically distinct regions of England was determined over a 3-month period in summer. Ultraviolet exposure was measured using personal film badges worn by each young person and time spent outdoors, in hourly intervals, assessed using exposure records. In each area a class of 9-10 year-old children from a primary school and a class of 14-15-year-old adolescents from a secondary school took part, giving a total of 180 subjects. We found that primary school children received higher outdoor ultraviolet exposure than young people in secondary schools, and geographical differences in exposure could not be accounted for solely by differences in ambient ultraviolet. There was little difference between the exposure of males and females. Children and adolescents did not behave as homogeneous groups with regard to exposure. (Author)

    Studies on human exposure to terrestrial radionuclides are important for human health. Therefore, this investigation presents aimed at making radiometric dosimetry Pocinhos municipality in the state of Paraiba. Monitoring was performed in 50 points in urban and rural areas Pocinhos. The estimated external effective dose rate in outdoor environments was obtained in triplicate using a portable gamma spectrometer, to 1.0 m away from the Earth's surface and time set acquisition in terms of environmental radiation levels. The values of these dose rates outdoor environments ranging from 0.53 to 3.94 mSv.y -1 . the arithmetic mean was 0.79 mSv.y -1 , which exceeds the value 0.07 mSv.y -1 corresponding to the global average in outdoor environments. In the city, found a higher radioactivity in rural areas that were uninhabited at the time of the survey. (Author)

  6. Evidence for object permanence in the smooth-pursuit eye movements of monkeys. (United States)

    Churchland, Mark M; Chou, I-Han; Lisberger, Stephen G


    We recorded the smooth-pursuit eye movements of monkeys in response to targets that were extinguished (blinked) for 200 ms in mid-trajectory. Eye velocity declined considerably during the target blinks, even when the blinks were completely predictable in time and space. Eye velocity declined whether blinks were presented during steady-state pursuit of a constant-velocity target, during initiation of pursuit before target velocity was reached, or during eye accelerations induced by a change in target velocity. When a physical occluder covered the trajectory of the target during blinks, creating the impression that the target moved behind it, the decline in eye velocity was reduced or abolished. If the target was occluded once the eye had reached target velocity, pursuit was only slightly poorer than normal, uninterrupted pursuit. In contrast, if the target was occluded during the initiation of pursuit, while the eye was accelerating toward target velocity, pursuit during occlusion was very different from normal pursuit. Eye velocity remained relatively stable during target occlusion, showing much less acceleration than normal pursuit and much less of a decline than was produced by a target blink. Anticipatory or predictive eye acceleration was typically observed just prior to the reappearance of the target. Computer simulations show that these results are best understood by assuming that a mechanism of eye-velocity memory remains engaged during target occlusion but is disengaged during target blinks.

  7. Smooth pursuit adaptation (SPA exhibits features useful to compensate changes in the properties of the smooth pursuit eye movement system due to usage.

    Directory of Open Access Journals (Sweden)

    Suryadeep eDash


    Full Text Available Smooth-pursuit adaptation (SPA refers to the fact that pursuit gain in the early, still open-loop response phase of the pursuit eye movement can be adjusted based on experience. For instance, if the target moves initially at a constant velocity for approximately 100-200ms and then steps to a higher velocity, subjects learn to up-regulate the pursuit gain associated with the initial target velocity (gain-increase SPA in order to reduce the retinal error resulting from the velocity step. Correspondingly, a step to a lower target velocity leads to a decrease in gain (gain-decrease SPA. In this study we demonstrate that the increase in peak eye velocity during gain-increase SPA is a consequence of expanding the duration of the eye acceleration profile while the decrease in peak velocity during gain-decrease SPA results from reduced peak eye acceleration but unaltered duration. Furthermore, we show that carrying out stereotypical smooth pursuit eye movements elicited by constant velocity target ramps for several hundred trials (= test of pursuit resilience leads to a clear drop in initial peak acceleration, a reflection of oculomotor and/ or cognitive fatigue. However, this drop in acceleration gets compensated by an increase in the duration of the acceleration profile, thereby keeping initial pursuit gain constant. The compensatory expansion of the acceleration profile in the pursuit resilience experiment is reminiscent of the one leading to gain-increase SPA, suggesting that both processes tap one and the same neuronal mechanism warranting a precise acceleration/ duration trade-off. Finally, we show that the ability to adjust acceleration duration during pursuit resilience depends on the integrity of the oculomotor vermis (OMV as indicated by the complete loss of the duration adjustment following a surgical lesion of the OMV in one rhesus monkey we could study.

    Iida, T.; Ikebe, Y.; Suzuki, K.; Ueno, K.; Komura, K.; Kato, I.; Jin Yihe


    The authors studied and developed an electrostatic 222 Rn monitor and have measured continuously outdoor radon ( 222 Rn) concentrations at Nagoya University since 1985. Four 222 Rn monitors were newly constructed to measure outdoor 222 Rn concentrations at other locations. The 222 Rn concentrations at Nagoya and Kasugai show a clear diurnal variation in autumn, and a seasonal pattern of a spring-summer minimum and a autumn-winter maximum. The results at Toki are the same pattern as that at Nagoya except spring. The concentrations at Kanazawa show a slight seasonal variation. A clear diurnal variation is observed in summer. (4 figs.)

  11. Adventures from Justin's Life: Engaging Your Physics Students (United States)

    Ridgley, James A.; Herron, Sherry S.


    Many teachers have had students ask the proverbial question, "When will I ever use this in my life?" In the sciences, especially physics, teachers seem to battle this torrent of indifference continually. Although many areas of our students' lives can distract them from their academic pursuits, we as teachers must be introspective in order to prevent our teaching style from becoming one of our students' potential distractions. For example, a problem source with teaching physics may be an inability to successfully pique students' interest in our lessons. According to Barrett, student engagement is critical in order for learning to occur. Student engagement is so crucially important that researchers from across the globe attempt to assist teachers in the careful construction of pedagogical "hooks" whereby they can actively engage their students. A student who is not academically engaged may find little use for what is presented and may be bored stiff during the lesson. Regardless of your theoretical perspectives on learning, constructivists to traditionalists alike have no excuse to be boring, and therefore should engage their students before presenting physics concepts.

  12. Fear of moving outdoors and development of outdoor walking difficulty in older people. (United States)

    Rantakokko, Merja; Mänty, Minna; Iwarsson, Susanne; Törmäkangas, Timo; Leinonen, Raija; Heikkinen, Eino; Rantanen, Taina


    To study which individual characteristics and environmental factors correlate with fear of moving outdoors and whether fear of moving outdoors predicts development of mobility limitation. Observational prospective cohort study and cross-sectional analyses. Community and research center. Seven hundred twenty-seven community-living people aged 75 to 81 were interviewed at baseline, of whom 314 took part in a 3.5-year follow-up. Fear of moving outdoors and its potential individual and environmental correlates were assessed at baseline. Perceived difficulties in walking 0.5 km and 2 km were assessed twice a year over a 3.5-year period. At baseline, 65% of the women and 29% of the men reported fear of moving outdoors. Poor socioeconomic status; musculoskeletal diseases; slow walking speed; and the presence of poor street conditions, hills in the nearby environment, and noisy traffic correlated with fear of moving outdoors. At the first 6-month follow-up, participants with fear of moving outdoors had more than four times the adjusted risk (odds ratio (OR)=4.6, 95% confidence interval (CI)=1.92-11.00) of developing difficulties in walking 0.5 km and a three times greater adjusted risk (OR=3.10, 95% CI=1.49-6.46) for developing difficulty in walking 2 km compared with those without fear. The difference in the prevalence of walking difficulties remained statistically significant over the 3.5-year follow-up (P=.02 and P=.009, respectively). Fear of moving outdoors is common in older adults and increases the risk of developing self-reported difficulties in walking 0.5 km and 2 km. Knowledge about individual and environmental factors underlying fear of moving outdoors and finding ways to alleviate fear of moving outdoors are important for community planning and prevention of disability.

  13. Wilderness medicine: strategies for provision of medical support for adventure racing. (United States)

    Townes, David A


    In adventure racing, or multisporting, athletes perform multiple disciplines over a course in rugged, often remote, wilderness terrain. Disciplines may include, but are not limited to, hiking, trail running, mountain biking, caving, technical climbing, fixed-line mountaineering, flat- and white-water boating, and orienteering. While sprint races may be as short as 6 hours, expedition-length adventure races last a minimum of 36 hours up to 10 days or more and may cover hundreds of kilometres. Over the past decade, adventure racing has grown in popularity throughout the world with increasing numbers of events and participants each year. The provision of on-site medical care during these events is essential to ensure the health and safety of the athletes and thus the success of the sport. At present, there are no formal guidelines and a relatively small amount of literature to assist in the development of medical support plans for these events. This article provides an introduction to the provision of medical support for adventure races. Since a wide variety of illness and injury occur during these events, the medical support plan should provide for proper personnel, equipment and supplies to provide care for a wide range of illness and injury. Foot-related problems are the most common reasons for athletes to require medical attention during these events. This article also highlights some of the controversies involved in the provision of medical support for these events. Suggested penalties for acceptance of medical care during the event and strategies for removal of an athlete from the event for medical reasons are offered. In addition, some of the challenges involved in the provision of medical support, including communication, logistics and liability are discussed. This information should prove useful for medical directors of future, similar events. Because of their extreme nature, expedition-length adventure races represent a new and unique area of wilderness and

  14. Adventure sports and sexual freedom hip replacement: the tripolar hip. (United States)

    Pritchett, James W


    Certain athletic activities and lifestyles require a completely stable and very mobile hip. Total hip replacement with a natural femoral head size and two mobile-bearing surfaces (i.e., a "tripolar" prosthesis) is the most stable prosthesis. Elegant design and wear-resistant bearing surfaces are the keys to long-term implant survivorship. The hypothesis is that a ceramic-coated tripolar prosthesis using highly cross-linked polyethylene can provide full function and complete stability with low wear. This study sought to determine: (1) patient-reported outcomes, (2) functional outcomes, (3) implant survivorship and complications, and (4) postoperative sexual limitations. Between 1998 and 2011, the author performed 160 primary total hip replacements using tripolar prostheses in patients participating in adventure sports and other physically demanding activities. The institutional review board approved this study. The inclusion criteria were patients who needed unrestricted activity and who were not candidates for or did not choose hip resurfacing. Patients were followed every second year and assessed with radiographs, Harris Hip Score, WOMAC, SF-12, and UCLA functional outcome scores. Patients were asked about symptoms of instability and satisfaction with their hip replacement. Patients were asked both preoperatively and 2 years postoperatively four questions about their sexual activity. Mean follow-up was 11 years. At 2 years' postoperatively, 98% of patients reported their satisfaction as excellent or good and 99% were not limited for sexual activity following surgery. Seventy-four percent of patients reported they were recovered within 6 weeks of surgery. There were no dislocations. There were three revision procedures for implant loosening, infection, and periprosthetic fracture, but there were no failures of the tripolar articulation. The mean postoperative UCLA score was the highly athletic score of 8. There were no signs of osteolysis, wear, or metal

  15. Fifty-four Years of Adventures in Infrared Astronomy (United States)

    Becklin, Eric Eric


    My adventures in infrared astronomy started when I was a grad student in 1965 with the discovery of an infrared-bright object (now known as the Becklin-Neugebauer Object) in the Orion Nebula. In 1966, I made the first measurements of the infrared radiation from the center of the Milky Way Galaxy. I was fortunate enough to be able to take advantage of the 2.2 micron sky survey carried out by Neugebauer and Leighton (1969), which produced many remarkable discoveries, the most spectacular being the heavily dust-embedded carbon star IRC+10216, thebrightest object in the sky at 5 microns outside the solar system. In the 1970’s there was a growth in Infrared astronomy with the availability of many new facilities such as the Kuiper Airborne Observatory, (KAO) which I used extensively with Mike Werner and Ian Gatley for many unique observations. In 1977, I moved to Hawaii to work on the NASA IRTF 3- meter telescope. Many discoveries were made, including the first direct measurements of the rings of Jupiter at 2.2 microns (with Gareth Wynn-Williams) and the discovery of the first L dwarf star around a white dwarf (with Ben Zuckerman). In the 1980’s the introduction of large format arrays changed the way we did infrared astronomy. With Ian McLean, I moved to UCLA in 1990 to start the IR lab and get involved in Keck development and science. In 1995, Andrea, Ghez, Mark Morris and I started looking for evidence of a possible massive Black Hole in the Galactic Center. Spectacular observations using the Keck10 meter telescopes with large format near-infrared arrays and adaptive optics led to the confirmation of the presence of such a black hole and an estimate of its mass (4xE6 M (Sun)). In 1996, I began working on the Stratospheric Observatory For Infrared Astronomy (SOFIA) and I will finish my talk by discussing SOFIA observations of the ring of dust and gas orbiting the massive black hole in the center

  16. Evaluation of Experiential Outdoor Research Locations in Asia for a K-12 school in Hong Kong (United States)

    Ibarra, D. L.; Joyce, S.


    A team of faculty and administrators from The Independent Schools Foundation Academy spend the 2015 - 2016 academic year identifying possible locations in Asia for a year-round outdoor education center. ISF Academy currently has over 1500 students its K-12 bilingual school in Hong Kong, China. The outdoor education center is an extension of the built campus in Pokfulam and will provide students opportunities to live in a natural setting, participate in outdoor educational activities and study in an environment significantly different than a classroom. Currently ISF Academy students in grades 4 - 12 are off campus twice during the academic year in an experiential learning environment. These current programs include camping, hiking, kayaking, other adventurous activities and service learning opportunities. The purpose of the dedicated site is to have a "home base" for ISF Academy and the experiential learning programs. This past year we looked specifically at programs and locations that could also be used by students for ecology and earth systems based research in the senior school (grades 9 - 12). We have looked at sites in Hong Kong, Indonesia, Malaysia and Taiwan. The ideal site will have marine, terrestrial and mangrove ecosystems and allow students to set up long-term research sites in any of these ecosystems. Creating opportunities for authentic research that allows students spend an extended time in a research setting will help them to gain both skills and independence needed in the future at the tertiary level. The evaluation of these sites included identifying potential research partners, site preparation, logistics in and out of the locations, and the heath/safety management of students living and working in a remote location. In parallel to the site evaluations, the curriculum is being developed for the students that is age and skill appropriate using the frame work of the existing guided discovery curriculum in the primary school, and the MYP and DP

  17. Cerenkov luminescence tomography based on preconditioning orthogonal matching pursuit (United States)

    Liu, Haixiao; Hu, Zhenhua; Wang, Kun; Tian, Jie; Yang, Xin


    Cerenkov luminescence imaging (CLI) is a novel optical imaging method and has been proved to be a potential substitute of the traditional radionuclide imaging such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT). This imaging method inherits the high sensitivity of nuclear medicine and low cost of optical molecular imaging. To obtain the depth information of the radioactive isotope, Cerenkov luminescence tomography (CLT) is established and the 3D distribution of the isotope is reconstructed. However, because of the strong absorption and scatter, the reconstruction of the CLT sources is always converted to an ill-posed linear system which is hard to be solved. In this work, the sparse nature of the light source was taken into account and the preconditioning orthogonal matching pursuit (POMP) method was established to effectively reduce the ill-posedness and obtain better reconstruction accuracy. To prove the accuracy and speed of this algorithm, a heterogeneous numerical phantom experiment and an in vivo mouse experiment were conducted. Both the simulation result and the mouse experiment showed that our reconstruction method can provide more accurate reconstruction result compared with the traditional Tikhonov regularization method and the ordinary orthogonal matching pursuit (OMP) method. Our reconstruction method will provide technical support for the biological application for Cerenkov luminescence.

  18. Fast and Epsilon-Optimal Discretized Pursuit Learning Automata. (United States)

    Zhang, JunQi; Wang, Cheng; Zhou, MengChu


    Learning automata (LA) are powerful tools for reinforcement learning. A discretized pursuit LA is the most popular one among them. During an iteration its operation consists of three basic phases: 1) selecting the next action; 2) finding the optimal estimated action; and 3) updating the state probability. However, when the number of actions is large, the learning becomes extremely slow because there are too many updates to be made at each iteration. The increased updates are mostly from phases 1 and 3. A new fast discretized pursuit LA with assured ε -optimality is proposed to perform both phases 1 and 3 with the computational complexity independent of the number of actions. Apart from its low computational complexity, it achieves faster convergence speed than the classical one when operating in stationary environments. This paper can promote the applications of LA toward the large-scale-action oriented area that requires efficient reinforcement learning tools with assured ε -optimality, fast convergence speed, and low computational complexity for each iteration.

  19. Trait motivation moderates neural activation associated with goal pursuit. (United States)

    Spielberg, Jeffrey M; Miller, Gregory A; Warren, Stacie L; Engels, Anna S; Crocker, Laura D; Sutton, Bradley P; Heller, Wendy


    Research has indicated that regions of left and right dorsolateral prefrontal cortex (DLPFC) are involved in integrating the motivational and executive function processes related to, respectively, approach and avoidance goals. Given that sensitivity to pleasant and unpleasant stimuli is an important feature of conceptualizations of approach and avoidance motivation, it is possible that these regions of DLPFC are preferentially activated by valenced stimuli. The present study tested this hypothesis by using a task in which goal pursuit was threatened by distraction from valenced stimuli while functional magnetic resonance imaging data were collected. The analyses examined whether the impact of trait approach and avoidance motivation on the neural processes associated with executive function differed depending on the valence or arousal level of the distractor stimuli. The present findings support the hypothesis that the regions of DLPFC under investigation are involved in integrating motivational and executive function processes, and they also indicate the involvement of a number of other brain areas in maintaining goal pursuit. However, DLPFC did not display differential sensitivity to valence.

  20. Hybrid Video Coding Based on Bidimensional Matching Pursuit

    Directory of Open Access Journals (Sweden)

    Lorenzo Granai


    Full Text Available Hybrid video coding combines together two stages: first, motion estimation and compensation predict each frame from the neighboring frames, then the prediction error is coded, reducing the correlation in the spatial domain. In this work, we focus on the latter stage, presenting a scheme that profits from some of the features introduced by the standard H.264/AVC for motion estimation and replaces the transform in the spatial domain. The prediction error is so coded using the matching pursuit algorithm which decomposes the signal over an appositely designed bidimensional, anisotropic, redundant dictionary. Comparisons are made among the proposed technique, H.264, and a DCT-based coding scheme. Moreover, we introduce fast techniques for atom selection, which exploit the spatial localization of the atoms. An adaptive coding scheme aimed at optimizing the resource allocation is also presented, together with a rate-distortion study for the matching pursuit algorithm. Results show that the proposed scheme outperforms the standard DCT, especially at very low bit rates.

  1. Illusory motion reveals velocity matching, not foveation, drives smooth pursuit of large objects. (United States)

    Ma, Zheng; Watamaniuk, Scott N J; Heinen, Stephen J


    When small objects move in a scene, we keep them foveated with smooth pursuit eye movements. Although large objects such as people and animals are common, it is nonetheless unknown how we pursue them since they cannot be foveated. It might be that the brain calculates an object's centroid, and then centers the eyes on it during pursuit as a foveation mechanism might. Alternatively, the brain merely matches the velocity by motion integration. We test these alternatives with an illusory motion stimulus that translates at a speed different from its retinal motion. The stimulus was a Gabor array that translated at a fixed velocity, with component Gabors that drifted with motion consistent or inconsistent with the translation. Velocity matching predicts different pursuit behaviors across drift conditions, while centroid matching predicts no difference. We also tested whether pursuit can segregate and ignore irrelevant local drifts when motion and centroid information are consistent by surrounding the Gabors with solid frames. Finally, observers judged the global translational speed of the Gabors to determine whether smooth pursuit and motion perception share mechanisms. We found that consistent Gabor motion enhanced pursuit gain while inconsistent, opposite motion diminished it, drawing the eyes away from the center of the stimulus and supporting a motion-based pursuit drive. Catch-up saccades tended to counter the position offset, directing the eyes opposite to the deviation caused by the pursuit gain change. Surrounding the Gabors with visible frames canceled both the gain increase and the compensatory saccades. Perceived speed was modulated analogous to pursuit gain. The results suggest that smooth pursuit of large stimuli depends on the magnitude of integrated retinal motion information, not its retinal location, and that the position system might be unnecessary for generating smooth velocity to large pursuit targets.

  11. The Influence of Money on Goal Pursuit and Decision-Making: Understanding Money's Unique Impact on Goal Pursuit (United States)

    Moran, Nora

    Previous research suggests that activating concepts of money and wealth can increase motivation to achieve personal goals. In this dissertation, I investigate how money affects pursuit of important personal goals, and how this motivation may be affected by goal attainability. In eight studies, I show that priming concepts of money and wealth leads individuals to pursue important personal goals to a greater degree than control groups, but only when a goal is more attainable. In contrast, when a goal is less attainable, those primed with money will be less likely to work towards goals relative to control groups. Furthermore, I examine why money may have a detrimental effect on motivation when individuals are faced with less attainable but important goals, and argue those primed with money become more concerned with maintaining a sense of efficacy, and thus disengage from pursuit when success is less certain. Thus, this research identifies the needs made salient by activating money--validating one's abilities. Finally, I show the relevance of these findings for consumer behavior, and discuss the additional implications of this work, as well as future research directions.

  12. Coordinated Control of Three-Dimensional Components of Smooth Pursuit to Rotating and Translating Textures. (United States)

    Edinger, Janick; Pai, Dinesh K; Spering, Miriam


    The neural control of pursuit eye movements to visual textures that simultaneously translate and rotate has largely been neglected. Here we propose that pursuit of such targets-texture pursuit-is a fully three-dimensional task that utilizes all three degrees of freedom of the eye, including torsion. Head-fixed healthy human adults (n = 8) tracked a translating and rotating random dot pattern, shown on a computer monitor, with their eyes. Horizontal, vertical, and torsional eye positions were recorded with a head-mounted eye tracker. The torsional component of pursuit is a function of the rotation of the texture, aligned with its visual properties. We observed distinct behaviors between those trials in which stimulus rotation was in the same direction as that of a rolling ball ("natural") in comparison to those with the opposite rotation ("unnatural"): Natural rotation enhanced and unnatural rotation reversed torsional velocity during pursuit, as compared to torsion triggered by a nonrotating random dot pattern. Natural rotation also triggered pursuit with a higher horizontal velocity gain and fewer and smaller corrective saccades. Furthermore, we show that horizontal corrective saccades are synchronized with torsional corrective saccades, indicating temporal coupling of horizontal and torsional saccade control. Pursuit eye movements have a torsional component that depends on the visual stimulus. Horizontal and torsional eye movements are separated in the motor periphery. Our findings suggest that translational and rotational motion signals might be coordinated in descending pursuit pathways.

  13. Expansion of direction space around the cardinal axes revealed by smooth pursuit eye movements (United States)

    Krukowski, Anton E.; Stone, Leland S.


    It is well established that perceptual direction discrimination shows an oblique effect; thresholds are higher for motion along diagonal directions than for motion along cardinal directions. Here, we compare simultaneous direction judgments and pursuit responses for the same motion stimuli and find that both pursuit and perceptual thresholds show similar anisotropies. The pursuit oblique effect is robust under a wide range of experimental manipulations, being largely resistant to changes in trajectory (radial versus tangential motion), speed (10 versus 25 deg/s), directional uncertainty (blocked versus randomly interleaved), and cognitive state (tracking alone versus concurrent tracking and perceptual tasks). Our data show that the pursuit oblique effect is caused by an effective expansion of direction space surrounding the cardinal directions and the requisite compression of space for other directions. This expansion suggests that the directions around the cardinal directions are in some way overrepresented in the visual cortical pathways that drive both smooth pursuit and perception.

  14. An International Polar Year Adventure in the Arctic (United States)

    Wartes, D.


    Native students in the UA system who participated in RAHI are nearly twice as likely to earn a bachelor's degree, than those who did not attend RAHI. The past two summers, in celebration of the International Polar Year, in collaboration with Ilisagvik College, at the completion of the traditional RAHI program, ten RAHI students flew to Barrow for an additional two weeks of study. Five students participated in an archaeological dig and five students performed research with the Barrow Arctic Science Consortium scientists studying climate change. And another student was the Alaskan delegate to the Students on Ice, a 2-week ship-based adventure in northern Canada. In addition, ten students from Greenland visited the program, with plans to more fully participate next summer. This added dimension to the program has proved successful, allowing the students to compare and contrast between their own countries and indigenous perspectives. Global warming was an issue that was hotly debated, as its effects are so evident in the Polar Regions. In the Arctic, one's life is directly tied to the ice and snow. As the ice disappears and/or changes, the Indigenous people have to adapt. RAHI would like to share with you some of the results of this past summer's IPY activities.

  16. Motivational pursuits in the context of human sexual relationships. (United States)

    Cooper, M Lynne; Barber, Lindsay L; Zhaoyang, Ruixue; Talley, Amelia E


    The current article examines how close relationships combine with individual differences in sex motives (Cooper, Shapiro, & Powers, 1998) to shape sexual experience. We first provide an overview of the motivational approach as it relates to sexual behavior and then describe 2 broad mechanisms (1 transactional, the other interactional) by which motives and relational context combine to shape behavior. Drawing on our past research, we review evidence showing that people select relationship contexts based partly on their motives and that these contexts in turn shape future motives and behavior; that partner motives shape sexual experience above and beyond one's own motives; and that both the broader relationship context and partner motives moderate the effects of one's own motives on sexual experience. We conclude that the nature of motivational pursuits cannot be adequately understood in the abstract, but rather we must take into account the relational context in which one's needs are pursued. © 2010 The Authors.

  17. Support agnostic Bayesian matching pursuit for block sparse signals

    KAUST Repository

    Masood, Mudassir


    A fast matching pursuit method using a Bayesian approach is introduced for block-sparse signal recovery. This method performs Bayesian estimates of block-sparse signals even when the distribution of active blocks is non-Gaussian or unknown. It is agnostic to the distribution of active blocks in the signal and utilizes a priori statistics of additive noise and the sparsity rate of the signal, which are shown to be easily estimated from data and no user intervention is required. The method requires a priori knowledge of block partition and utilizes a greedy approach and order-recursive updates of its metrics to find the most dominant sparse supports to determine the approximate minimum mean square error (MMSE) estimate of the block-sparse signal. Simulation results demonstrate the power and robustness of our proposed estimator. © 2013 IEEE.

  19. Smooth Pursuit Saccade Amplitude Modulation During Exposure to Microgravity (United States)

    Reschke, M. F.; Kozlovskaya, I. B.; Sayenko, D. G.; Sayenko, I.; Somers, J. T.; Paloski, W. H.


    Russian investigators have reported changes in pursuit tracking of a vertically moving point stimulus during space flight. Early in microgravity, changes were manifested by decreased eye movement amplitude (undershooting) and the appearance of correction saccades. As the flight progressed, pursuit of the moving point stimulus deteriorated while associated saccadic movements were unchanged. Immediately postflight there was an improved execution of active head movements indicating that the deficiencies in pursuit function noted in microgravity may be of central origin. In contrast, tests of two cosmonauts showed that horizontal and vertical smooth pursuit were unchanged inflight. However, results of corresponding saccadic tasks showed a tendency toward the overshooting of a horizontal target early inflight with high accuracy developing later inflight, accompanied by an increased saccade velocity and a trend toward decreased saccade latency. Based on these equivocal results, we have further investigated the effects of space flight on the smooth pursuit mechanism during and after short duration flight, and postflight on returning MIR crewmembers. Sinusoidal target movement was presented horizontally at frequencies of 0.33 and 1.0 Hz. Subjects were asked to perform two trials for each stimulus combination: (1) moving eyes-only (EO) and (2) moving eyes and head (EH) with the target motion. Peak amplitude was 30 deg for 0.33 Hz trials and 15 deg for the 1.0 Hz trials. The relationship between saccade amplitude and peak velocity were plotted as a main sequence for each phase of flight, and linear regression analysis allowed us to determine the slope of each main sequence plot. The linear slopes were then combined for each flight phase for each individual subject. The main sequence for both EO and EH trials at both the 0.33 and 1.0 Hz frequencies during flight for the short duration flyers showed a reduction in saccade velocity and amplitude when compared to the preflight

  20. Prescribing Outdoor Physical Activity to Children: Health Care Providers’ Perspectives (United States)

    Christiana, Richard W.; James, J. Joy; Battista, Rebecca A.


    Little evidence exists on health care provider (HCP) prescriptions for children’s outdoor physical activity (PA). Semistructured interviews were conducted with 15 children’s HCPs to explore perspectives on outdoor PA prescription programs for children and barriers to implementation. Thematic analytic techniques were used to analyze the data. Most participants reported an awareness of health benefits to children being in the outdoors. Ten themes emerged from the data related to 3 thematic categories: (1) current strategies that HCPs are using to promote PA among children, (2) barriers that HCPs see to prescribing outdoor PA, and (3) potential strategies for promoting outdoor PA among children. Assessment of the local outdoor PA environment and resource development must be done prior to a prescription program. HCPs should be skilled in conducting conversations and setting goals related to outdoor PA tailored to the patient. Developing a system for follow-up with patients on established goals should also be included. PMID:29152542

  2. Adventure of Architecture Example of Housing and Housing Areas

    Directory of Open Access Journals (Sweden)

    Ali Asasoğlu


    Full Text Available Housing and the concept of space associated with this requirement are among the initial attitudes towards the human reign over the nature. The dawn of the structured environment found life with this approach within the nature. Both, housing and the housing design process overlap with the historical development of modern man, and is covered within the concept of architecture today. The contribution made by culture within this period is yet another undeniable fact. While the interaction between architecture and culture are moving forward thereby leaving traces in every era throughout the history, the culture of housing and housing design exhibits a parallel attitude which is a subsidiary, yet a highly title with a close human relationship. Culture and architecture are two closely interacting aspects which are drawing the borders of each other from time to time, hinting at quality and quantity, and evaluating such. Quite naturally, the structure which is in a deep relationship with mankind is in an exchange with all physical, social and economic qualities of the human. These qualities are fundamental determinants of the concept of culture as a human trait. The process of architecture which is usually defined as a sequence of eras that involve social movements, impulses and trends, sometimes kept moving ahead in the pursuit of individual leadership and styles. The concerns regarding the solution of space problems, setting up /designing venues and arranging the environment in line with the requirements brought up increasingly complex issues and stacks of solutions which follow such problems. It is this dynamic structure which forms the basis of the architectural problem to date. Starting with the housing and residential concepts, this study brings a critical view on the application samples and methods of the relationship between architecture and culture in terms of our country in particular while putting emphasis on the architectural venture of the

  7. Monitoring injury in the New Zealand adventure tourism sector: an operator survey. (United States)

    Bentley, Tim A; Page, Stephen; Edwards, Joanna


    Client safety is a major risk management concern for the commercial adventure tourism sector in New Zealand. This study built on previous exploratory analyses of New Zealand adventure tourism safety, including industry surveys conducted by these authors in 1999 and 2003. The aims of the study were to provide a continuation of injury monitoring across the sector through data collected from self-reported injury incidence by industry operators and to compare findings with those from other primary and secondary research studies conducted by the authors. A postal questionnaire was used to survey all identifiable New Zealand adventure tourism operators during 2006. The questionnaire asked respondents about their recorded client injury experience, perceptions of client injury risk factors, and safety management practices. Some 21 adventure tourism activities were represented among the responding sample (n = 127), with most operations being very small in terms of staff numbers, although responding operators catered to nearly 1 million clients in total annually. Highest ranked risk factors for client injury included clients not following instructions; level of client skill, ability, and fitness; and changeable/unpredictable weather conditions. Highest client injury was reported for horse riding, ecotourism, and white water rafting sectors, although serious underreporting of minor injuries was evidenced across the sector. Slips, trips, and falls were the most frequently reported injury mechanism, while safety management measures were inconsistently applied across the sector. The industry should address reporting culture issues and safety management practices generally. Specifically, the industry should consider risk management that focuses on minor (eg, falls) as well as catastrophic events.

Nearby outdoor environments on residential sites may impact older inhabitants׳ physical activities there (defined as walking, gardening, yard work, and other outdoor physical activities on residential sites. This study surveyed 110 assisted-living residents in Houston, Texas, regarding their previous residential sites before moving to a retirement community and physical activities there. Twelve environmental features were studied under four categories (typology, motivators, function, and safety. Based on data availability, a subset of 57 sample sites was analyzed in Geographic Information Systems. Hierarchical linear modeling was applied to estimate physical activities as a function of the environments. Higher levels of physical activity were found to be positively related with four environmental features (transitional-areas, connecting-paths, walk-ability, and less paving.

  9. Metrology for fire experiments in outdoor conditions

    CERN Document Server

    Silvani, Xavier


    Natural fires can be considered as scale-dependant, non-linear processes of mass, momentum and heat transport, resulting from a turbulent reactive and radiative fluid medium flowing over a complex medium, the vegetal fuel. In natural outdoor conditions, the experimental study of natural fires at real scale needs the development of an original metrology, one able to capture the large range of time and length scales involved in its dynamic nature and also able to resist the thermal, mechanical and chemical aggression of flames on devices. Robust, accurate and poorly intrusive tools must be carefully set-up and used for gaining very fluctuating data over long periods. These signals also need the development of original post-processing tools that take into account the non-steady nature of their stochastic components.

  14. Professional judgement and decision-making in adventure sports coaching: the role of interaction. (United States)

    Collins, Loel; Collins, Dave


    This qualitative study presents the view that coaching practice places demands on the coach's adaptability and flexibility. These requirements for being adaptive and flexible are met through a careful process of professional judgement and decision-making based on context-appropriate bodies of knowledge. Adventure sports coaches were selected for study on the basis that adventure sports create a hyper-dynamic environment in which these features can be examined. Thematic analysis revealed that coaches were generally well informed and practised with respect to the technical aspects of their sporting disciplines. Less positively, however, they often relied on ad hoc contextualisation of generalised theories of coaching practice to respond to the hyper-dynamic environments encountered in adventure sports. We propose that coaching practice reflects the demands of the environment, individual learning needs of the students and the task at hand. Together, these factors outwardly resemble a constraints-led approach but, we suggest, actually reflect manipulation of these parameters from a cognitive rather than an ecological perspective. This process is facilitated by a refined judgement and decision-making process, sophisticated epistemology and an explicit interaction of coaching components.

  15. Premotor neurons encode torsional eye velocity during smooth-pursuit eye movements (United States)

    Angelaki, Dora E.; Dickman, J. David


    Responses to horizontal and vertical ocular pursuit and head and body rotation in multiple planes were recorded in eye movement-sensitive neurons in the rostral vestibular nuclei (VN) of two rhesus monkeys. When tested during pursuit through primary eye position, the majority of the cells preferred either horizontal or vertical target motion. During pursuit of targets that moved horizontally at different vertical eccentricities or vertically at different horizontal eccentricities, eye angular velocity has been shown to include a torsional component the amplitude of which is proportional to half the gaze angle ("half-angle rule" of Listing's law). Approximately half of the neurons, the majority of which were characterized as "vertical" during pursuit through primary position, exhibited significant changes in their response gain and/or phase as a function of gaze eccentricity during pursuit, as if they were also sensitive to torsional eye velocity. Multiple linear regression analysis revealed a significant contribution of torsional eye movement sensitivity to the responsiveness of the cells. These findings suggest that many VN neurons encode three-dimensional angular velocity, rather than the two-dimensional derivative of eye position, during smooth-pursuit eye movements. Although no clear clustering of pursuit preferred-direction vectors along the semicircular canal axes was observed, the sensitivity of VN neurons to torsional eye movements might reflect a preservation of similar premotor coding of visual and vestibular-driven slow eye movements for both lateral-eyed and foveate species.

  16. Competition between color and luminance for target selection in smooth pursuit and saccadic eye movements. (United States)

    Spering, Miriam; Montagnini, Anna; Gegenfurtner, Karl R


    Visual processing of color and luminance for smooth pursuit and saccadic eye movements was investigated using a target selection paradigm. In two experiments, stimuli were varied along the dimensions color and luminance, and selection of the more salient target was compared in pursuit and saccades. Initial pursuit was biased in the direction of the luminance component whereas saccades showed a relative preference for color. An early pursuit response toward luminance was often reversed to color by a later saccade. Observers' perceptual judgments of stimulus salience, obtained in two control experiments, were clearly biased toward luminance. This choice bias in perceptual data implies that the initial short-latency pursuit response agrees with perceptual judgments. In contrast, saccades, which have a longer latency than pursuit, do not seem to follow the perceptual judgment of salience but instead show a stronger relative preference for color. These substantial differences in target selection imply that target selection processes for pursuit and saccadic eye movements use distinctly different weights for color and luminance stimuli.

  17. Injury and illness in college outdoor education. (United States)

    Gaudio, Flavio G; Greenwald, Peter W; Holton, Mark


    Many colleges offer outdoor education courses such as rock climbing, kayaking, and mountain biking. Since these sports may be perceived as dangerous, we describe the prevalence of injuries and illnesses in a large, university-based outdoor education program. We also compare composite incident rates from this outdoor program to those of traditional college sports. Cohort of college students participating in either Cornell Outdoor Education (COE) or National Collegiate Athletic Association (NCAA) sports and comparison of incident rates. COE data were prospectively collected in the field; and NCAA data were prospectively collected through the Association's Injury Surveillance System. By definition, a COE injury or illness required follow-up care, prescription medication, or limited course participation. Similarly, a NCAA injury limited further practice or play. Incident rates were calculated as injuries and illnesses per 1000 participant-days (COE) or injuries per 1000 athlete-exposures (NCAA). Included COE courses during 2002-2007 totaled 74 005 participant-days. There were 111 injuries and illnesses, rate = 1.50/1000 participant-days (95% CI 1.24-1.81). The NCAA reported 32 646 899 athlete-exposures during 1988-2004 and 181 476 injuries, rate = 5.56/1000 athlete-exposures (95% CI 5.53-5.58). Compared to COE, the relative risk of injury in NCAA sports was 3.7 (95% CI 3.1-4.5) overall and 3.3 (95% CI 2.8-4.0) after excluding the high-contact sports of football, ice hockey, and wrestling. For COE, mountain biking had the highest incident rate (7.5/1000), which was significantly lower than game injury rates in NCAA football and soccer. The most common injuries for both NCAA and COE were soft-tissue injuries such as sprains and strains. Outdoor education at this university-sponsored program was at least as safe as traditional college sports. Overall, college students were less likely to be injured while participating in COE courses than while participating in NCAA sports

  18. Experimental evaluation of user performance in a pursuit tracking task with multimodal feedback

    Directory of Open Access Journals (Sweden)

    Obrenović Željko


    Full Text Available In this paper we describe the results of experimental evaluation of user performance in a pursuit-tracking task with multimodal feedback. Our experimental results indicate that audio can significantly improve the accuracy of pursuit tracking. Experiments with 19 participants have shown that addition of acoustic modalities reduces the error during pursuit tracking for up to 19%. Moreover, experiments indicated the existence of perceptual boundaries of multimodal HCI for different scene complexity and target speeds. We have also shown that the most appealing paradigms are not the most effective ones, which necessitates a careful quantitative analysis of proposed multimodal HCI paradigms.

  19. Abnormalities of fixation, saccade and pursuit in posterior cortical atrophy. (United States)

    Shakespeare, Timothy J; Kaski, Diego; Yong, Keir X X; Paterson, Ross W; Slattery, Catherine F; Ryan, Natalie S; Schott, Jonathan M; Crutch, Sebastian J


    The clinico-neuroradiological syndrome posterior cortical atrophy is the cardinal 'visual dementia' and most common atypical Alzheimer's disease phenotype, offering insights into mechanisms underlying clinical heterogeneity, pathological propagation and basic visual phenomena (e.g. visual crowding). Given the extensive attention paid to patients' (higher order) perceptual function, it is surprising that there have been no systematic analyses of basic oculomotor function in this population. Here 20 patients with posterior cortical atrophy, 17 patients with typical Alzheimer's disease and 22 healthy controls completed tests of fixation, saccade (including fixation/target gap and overlap conditions) and smooth pursuit eye movements using an infrared pupil-tracking system. Participants underwent detailed neuropsychological and neurological examinations, with a proportion also undertaking brain imaging and analysis of molecular pathology. In contrast to informal clinical evaluations of oculomotor dysfunction frequency (previous studies: 38%, current clinical examination: 33%), detailed eyetracking investigations revealed eye movement abnormalities in 80% of patients with posterior cortical atrophy (compared to 17% typical Alzheimer's disease, 5% controls). The greatest differences between posterior cortical atrophy and typical Alzheimer's disease were seen in saccadic performance. Patients with posterior cortical atrophy made significantly shorter saccades especially for distant targets. They also exhibited a significant exacerbation of the normal gap/overlap effect, consistent with 'sticky fixation'. Time to reach saccadic targets was significantly associated with parietal and occipital cortical thickness measures. On fixation stability tasks, patients with typical Alzheimer's disease showed more square wave jerks whose frequency was associated with lower cerebellar grey matter volume, while patients with posterior cortical atrophy showed large saccadic intrusions

  20. Counseling for the Wilderness Athlete and Adventurer During a Preparticipation Evaluation for Preparation, Safety, and Injury Prevention. (United States)

    Young, Justin Mark J; Campbell, Aaron D; Raastad, Kate K


    Wilderness sports and adventures continue to increase in popularity. Counseling is an essential element of the preparticipation evaluation (PPE) for athletes in traditional sports. This approach can be applied to and augmented for the wilderness athlete and adventurer. The authors reviewed the literature on counseling during PPEs and gathered expert opinion from medical professionals who perform such PPEs for wilderness sports enthusiasts. The objective was to present findings of this review and make recommendations on the counseling component of a wilderness sports/adventure PPE. The counseling component of a PPE for wilderness sports/adventures should take place after a basic medical evaluation, and include a discussion on sport or activity-specific injury prevention, personal health, travel recommendations, and emergency event planning. Counseling should be individualized and thorough, and involve shared decision making. This should take place early enough to allow ample time for the athlete or adventurer to further prepare as needed based on the recommendations. Resources may be recommended for individuals desiring more information on selected topics. Copyright © 2015. Published by Elsevier Inc.

  2. Untrivial Pursuit: Measuring Motor Procedures Learning in Children with Autism. (United States)

    Sparaci, Laura; Formica, Domenico; Lasorsa, Francesca Romana; Mazzone, Luigi; Valeri, Giovanni; Vicari, Stefano


    Numerous studies have underscored prevalence of motor impairments in children with autism spectrum disorders (ASD), but only few of them have analyzed motor strategies exploited by ASD children when learning a new motor procedure. To evaluate motor procedure learning and performance strategies in both ASD and typically developing (TD) children, we built a virtual pursuit rotor (VPR) task, requiring tracking a moving target on a computer screen using a digitalized pen and tablet. Procedural learning was measured as increased time on target (TT) across blocks of trials on the same day and consolidation was assessed after a 24-hour rest. The program and the experimental setting (evaluated in a first experiment considering two groups of TD children) allowed also measures of continuous time on target (CTT), distance from target (DT) and distance from path (DP), as well as 2D reconstructions of children's trajectories. Results showed that the VPR was harder for children with ASD than for TD controls matched for chronological age and intelligence quotient, but both groups displayed comparable motor procedure learning (i.e., similarly incremented their TT). However, closer analysis of CTT, DT, and DP as well as 2D trajectories, showed different motor performance strategies in ASD, highlighting difficulties in overall actions planning. Data underscore the need for deeper investigations of motor strategies exploited by children with ASD when learning a new motor procedure. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

  3. Immanent Politics, Participatory Democracy, and the Pursuit of Eudaimonia

    Directory of Open Access Journals (Sweden)

    Geoffrey Allan Plauché


    Full Text Available This paper builds on the burgeoning tradition of Aristotelian liberalism. It identifies and critiques a fundamental inequality inherent in the nature of the state and, in particular, the liberal representative-democratic state: namely, an institutionalized inequality in authority. The analysis draws on and synthesizes disparate philosophical and political traditions: Aristotle’s virtue ethics and politics, Locke’s natural rights and idea of equality in authority in the state of nature (sans state of nature, the New Left’s conception of participatory democracy (particularly as described in a number of under-utilized essays by Murray Rothbard and Don Lavoie, and philosophical anarchism. The deleterious consequences of this fundamental institutionalized inequality are explored, including on social justice and economic progress, on individual autonomy, on direct and meaningful civic and political participation, and the creation and maintenance of other artificial inequalities as well as the exacerbation of natural inequalities (economic and others. In the process, the paper briefly sketches a neo-Aristotelian theory of virtue ethics and natural individual rights, for which the principle of equal and total liberty for all is of fundamental political importance. And, finally, a non-statist conception of politics is developed, with politics defined as discourse and deliberation between equals (in authority in joint pursuit of eudaimonia (flourishing, well-being.[Note: The following font file may be useful for viewing the Greek characters in the Word file above: SPIONIC_.TTF.

  4. Altered velocity processing in schizophrenia during pursuit eye tracking.

    Directory of Open Access Journals (Sweden)

    Matthias Nagel

    Full Text Available Smooth pursuit eye movements (SPEM are needed to keep the retinal image of slowly moving objects within the fovea. Depending on the task, about 50%-80% of patients with schizophrenia have difficulties in maintaining SPEM. We designed a study that comprised different target velocities as well as testing for internal (extraretinal guidance of SPEM in the absence of a visual target. We applied event-related fMRI by presenting four velocities (5, 10, 15, 20°/s both with and without intervals of target blanking. 17 patients and 16 healthy participants were included. Eye movements were registered during scanning sessions. Statistical analysis included mixed ANOVAs and regression analyses of the target velocity on the Blood Oxygen Level Dependency (BOLD signal. The main effect group and the interaction of velocity×group revealed reduced activation in V5 and putamen but increased activation of cerebellar regions in patients. Regression analysis showed that activation in supplementary eye field, putamen, and cerebellum was not correlated to target velocity in patients in contrast to controls. Furthermore, activation in V5 and in intraparietal sulcus (putative LIP bilaterally was less strongly correlated to target velocity in patients than controls. Altered correlation of target velocity and neural activation in the cortical network supporting SPEM (V5, SEF, LIP, putamen implies impaired transformation of the visual motion signal into an adequate motor command in patients. Cerebellar regions seem to be involved in compensatory mechanisms although cerebellar activity in patients was not related to target velocity.

  6. Fast Component Pursuit for Large-Scale Inverse Covariance Estimation. (United States)

    Han, Lei; Zhang, Yu; Zhang, Tong


    The maximum likelihood estimation (MLE) for the Gaussian graphical model, which is also known as the inverse covariance estimation problem, has gained increasing interest recently. Most existing works assume that inverse covariance estimators contain sparse structure and then construct models with the ℓ 1 regularization. In this paper, different from existing works, we study the inverse covariance estimation problem from another perspective by efficiently modeling the low-rank structure in the inverse covariance, which is assumed to be a combination of a low-rank part and a diagonal matrix. One motivation for this assumption is that the low-rank structure is common in many applications including the climate and financial analysis, and another one is that such assumption can reduce the computational complexity when computing its inverse. Specifically, we propose an efficient COmponent Pursuit (COP) method to obtain the low-rank part, where each component can be sparse. For optimization, the COP method greedily learns a rank-one component in each iteration by maximizing the log-likelihood. Moreover, the COP algorithm enjoys several appealing properties including the existence of an efficient solution in each iteration and the theoretical guarantee on the convergence of this greedy approach. Experiments on large-scale synthetic and real-world datasets including thousands of millions variables show that the COP method is faster than the state-of-the-art techniques for the inverse covariance estimation problem when achieving comparable log-likelihood on test data.

    Full Text Available We consider a linear pursuit differential game of one pursuer and one evader. Controls of the pursuer and evader are subjected to integral and geometric constraints, respectively. In addition, phase constraint is imposed on the state of evader, whereas pursuer moves throughout the space. We say that pursuit is completed, if inclusion y(t1-x(t1∈M is satisfied at some t1>0, where x(t and y(t are states of pursuer and evader, respectively, and M is terminal set. Conditions of completion of pursuit in the game from all initial points of players are obtained. Strategy of the pursuer is constructed so that the phase vector of the pursuer first is brought to a given set, and then pursuit is completed.

  20. The Role of Dopamine in Anticipatory Pursuit Eye Movements: Insights from Genetic Polymorphisms in Healthy Adults. (United States)

    Billino, Jutta; Hennig, Jürgen; Gegenfurtner, Karl R


    There is a long history of eye movement research in patients with psychiatric diseases for which dysfunctions of neurotransmission are considered to be the major pathologic mechanism. However, neuromodulation of oculomotor control is still hardly understood. We aimed to investigate in particular the impact of dopamine on smooth pursuit eye movements. Systematic variability in dopaminergic transmission due to genetic polymorphisms in healthy subjects offers a noninvasive opportunity to determine functional associations. We measured smooth pursuit in 110 healthy subjects genotyped for two well-documented polymorphisms, the COMT Val 158 Met polymorphism and the SLC6A3 3'-UTR-VNTR polymorphism. Pursuit paradigms were chosen to particularly assess the ability of the pursuit system to initiate tracking when target motion onset is blanked, reflecting the impact of extraretinal signals. In contrast, when following a fully visible target sensory, retinal signals are available. Our results highlight the crucial functional role of dopamine for anticipatory, but not for sensory-driven, pursuit processes. We found the COMT Val 158 Met polymorphism specifically associated with anticipatory pursuit parameters, emphasizing the dominant impact of prefrontal dopamine activity on complex oculomotor control. In contrast, modulation of striatal dopamine activity by the SLC6A3 3'-UTR-VNTR polymorphism had no significant functional effect. Though often neglected so far, individual differences in healthy subjects provide a promising approach to uncovering functional mechanisms and can be used as a bridge to understanding deficits in patients.

  1. Keep your eyes on the ball: smooth pursuit eye movements enhance prediction of visual motion. (United States)

    Spering, Miriam; Schütz, Alexander C; Braun, Doris I; Gegenfurtner, Karl R


    Success of motor behavior often depends on the ability to predict the path of moving objects. Here we asked whether tracking a visual object with smooth pursuit eye movements helps to predict its motion direction. We developed a paradigm, "eye soccer," in which observers had to either track or fixate a visual target (ball) and judge whether it would have hit or missed a stationary vertical line segment (goal). Ball and goal were presented briefly for 100-500 ms and disappeared from the screen together before the perceptual judgment was prompted. In pursuit conditions, the ball moved towards the goal; in fixation conditions, the goal moved towards the stationary ball, resulting in similar retinal stimulation during pursuit and fixation. We also tested the condition in which the goal was fixated and the ball moved. Motion direction prediction was significantly better in pursuit than in fixation trials, regardless of whether ball or goal served as fixation target. In both fixation and pursuit trials, prediction performance was better when eye movements were accurate. Performance also increased with shorter ball-goal distance and longer presentation duration. A longer trajectory did not affect performance. During pursuit, an efference copy signal might provide additional motion information, leading to the advantage in motion prediction.

  2. Environmental Service and Outdoor Adventure as a Context for Positive Youth Development: An Evaluation of the Crow River Trail Guards Program

    Directory of Open Access Journals (Sweden)

    Julie Ernst


    Full Text Available Trail Guards, a community-based organization in Minnesota, offers youth the opportunity to participate in park/trail maintenance and enhancement projects. Through these environmental service projects, Trail Guards seeks to foster the following developmental outcomes in youth participants: self-awareness of skills and strengths; self-worth; personal and social self-efficacy; sense of belonging and acceptance; team work and cooperation skills; and a sense of community responsibility. Trail Guards ultimately aims for youth to transfer these skills and socially appropriate behaviors to settings and activities beyond Trail Guards and to participate in the community in other positive ways. A program evaluation indicated Trail Guards seems to be achieving these youth development outcomes, and that the success of the program may be attributed to the program leader serving as a positive adult role model and providing a safe and caring environment, as well as to community involvement. Implications are discussed.

    This paper provided an update to the Toronto Atmospheric Fund (TAF) LightSavers program. The program was designed to accelerate market transformation for light emitting diode (LED) and advanced lighting management systems in outdoor lighting applications. It is expected that the program will result in significant electricity savings and emissions reductions within the Greater Toronto Area (GTA) and other Ontario municipalities. The first phase of the program established advanced outdoor lighting pilot programs in parking lots, garages, and pathway lighting applications that were guided by a common monitoring protocol to ensure useful and reliable assessment of the pilot programs. The TAF has since developed a strategy to strengthen public understanding and support for the use of advanced lighting, and continues to address policy issues that may impact the future of LED lighting programs. The TAF has also activated an electronic newsletter, delivered public workshops, and has been represented at several conferences. A working partnership has been established with Toronto Hydro Energy Services. Five pilot sites have been installed and have begun to provide monitoring data. Details of the pilot programs were provided. 16 figs.

  4. Indoor versus outdoor time in preschoolers at child care. (United States)

    Tandon, Pooja S; Saelens, Brian E; Zhou, Chuan; Kerr, Jacqueline; Christakis, Dimitri A


    Being outdoors may have health benefits including being more physically active. Understanding the relationship between outdoor time and health is hampered by the difficulty of measuring outdoor time. To examine the accuracy and validity of light-sensor and GPS methods for quantifying outdoor time among those aged 3-5 years at child care. A total of 45 children (mean age 4.5 years, 64% boys) from five child care centers wore portable accelerometers with built-in light sensors and a separate GPS device around their waists during child care, providing 80,648 episodes (15 seconds each) for analysis. Direct observation (gold standard) of children being outdoors versus indoors was conducted for 2 days at each center. GPS signal-to-noise ratios, processed through the Personal Activity and Location Measurement System were used to define indoor versus outdoor locations. Receiver operating characteristic (ROC) analyses were used to determine thresholds for defining being indoors versus outdoors. Data were collected in Fall 2011, analyzed in 2012. Mean observed outdoor time was 63 [±44; range: 18-152] minutes/day. Mean light-sensor levels were significantly higher outdoors. The area under the ROC curve for location based on light sensor for all weather conditions was 0.82 (range: 0.70 on partly cloudy days to 0.97 on sunny days); for GPS, it was 0.89. The light sensor had a sensitivity of 74% and specificity of 86%. GPS had a sensitivity of 82% and specificity of 88%. A light sensor and a GPS device both distinguish indoor from outdoor time for preschoolers with moderate to high levels of accuracy. These devices can increase the feasibility and lower the cost of measuring outdoor time in studies of preschool children. Copyright © 2013 American Journal of Preventive Medicine.

    A is for anchoring the delivery of your research to your audience in a standard-aligned curriculum. B is for BGAN Satellite Communication System assisting in delivering real-time authentic media. C is for a collaborative online learning environment to engage learners" Z is for the peaceful sleep you will get once your program is up and running! As part of Team GoNorth! ( it is our job to deliver adventure learning. We set out to do this back when the computer was a 4-foot, 50-lb box powered by a hand-crank where one would have a window of ten minutes in a 24-hour period to catch the satellite (before Al Gore created the Internet!). Every year we review the quantum leaps in what is now possible from the field and in the classroom, and over the years we have wrestled technical issues, solutions and numerous re-structures in the process of our of curriculum development. With this presentation we will provide some basic ABC's on how you can remained focused on your research, yet deliver an adventure learning program for learners to investigate real-world issues within your scientific research. Our scales are most likely different. The volume of our curriculum is an annual production of 4-500 pages to be used from Kindergarden through 12th grade around the world. The framework of our online learning environment must be able to supports millions of users at a time. "In the field" means on a a 3-4 month dogsled expedition - so sending out our live updates involve thawing out the computers and setting up the satellite communication system to work in a ground blizzard! But regardless of the scope and location of your field research, you can probably build on some of our experiences in the planning of an upcoming adventure learning program to engage learners of all or any ages in your scientific explorations!

  7. Wilderness adventure therapy effects on the mental health of youth participants. (United States)

    Bowen, Daniel J; Neill, James T; Crisp, Simon J R


    Adventure therapy offers a prevention, early intervention, and treatment modality for people with behavioural, psychological, and psychosocial issues. It can appeal to youth-at-risk who are often less responsive to traditional psychotherapeutic interventions. This study evaluated Wilderness Adventure Therapy (WAT) outcomes based on participants' pre-program, post-program, and follow-up responses to self-report questionnaires. The sample consisted of 36 adolescent out-patients with mixed mental health issues who completed a 10-week, manualised WAT intervention. The overall short-term standardised mean effect size was small, positive, and statistically significant (0.26), with moderate, statistically significant improvements in psychological resilience and social self-esteem. Total short-term effects were within age-based adventure therapy meta-analytic benchmark 90% confidence intervals, except for the change in suicidality which was lower than the comparable benchmark. The short-term changes were retained at the three-month follow-up, except for family functioning (significant reduction) and suicidality (significant improvement). For participants in clinical ranges pre-program, there was a large, statistically significant reduction in depressive symptomology, and large to very large, statistically significant improvements in behavioural and emotional functioning. These changes were retained at the three-month follow-up. These findings indicate that WAT is as effective as traditional psychotherapy techniques for clinically symptomatic people. Future research utilising a comparison or wait-list control group, multiple sources of data, and a larger sample, could help to qualify and extend these findings. Copyright © 2016 The Authors.

  10. Stamina, speed and adventure: Australian women and competitive cycling in the 1890s. (United States)

    Kinsey, Fiona


    The scholarship surrounding women's cycling in Australia during the 1890s is slim. However, a focus on female competitive cycling, just one of many diverse cycling activities that women pursued in this era, reveals a rich seam of information. Accordingly, this paper surveys endurance riding, adventure touring and racing, introducing new historical and biographical detail and highlighting the significance of competitive cycling for women in the late nineteenth century. The discussion shows that women's competitive cycling constituted a significant component of Australian cycling history, and helped to re-define women's identity in an era when feminine roles were in flux and the traditional gender order was being contested.

  18. Shared sensory estimates for human motion perception and pursuit eye movements. (United States)

    Mukherjee, Trishna; Battifarano, Matthew; Simoncini, Claudio; Osborne, Leslie C


    Are sensory estimates formed centrally in the brain and then shared between perceptual and motor pathways or is centrally represented sensory activity decoded independently to drive awareness and action? Questions about the brain's information flow pose a challenge because systems-level estimates of environmental signals are only accessible indirectly as behavior. Assessing whether sensory estimates are shared between perceptual and motor circuits requires comparing perceptual reports with motor behavior arising from the same sensory activity. Extrastriate visual cortex both mediates the perception of visual motion and provides the visual inputs for behaviors such as smooth pursuit eye movements. Pursuit has been a valuable testing ground for theories of sensory information processing because the neural circuits and physiological response properties of motion-responsive cortical areas are well studied, sensory estimates of visual motion signals are formed quickly, and the initiation of pursuit is closely coupled to sensory estimates of target motion. Here, we analyzed variability in visually driven smooth pursuit and perceptual reports of target direction and speed in human subjects while we manipulated the signal-to-noise level of motion estimates. Comparable levels of variability throughout viewing time and across conditions provide evidence for shared noise sources in the perception and action pathways arising from a common sensory estimate. We found that conditions that create poor, low-gain pursuit create a discrepancy between the precision of perception and that of pursuit. Differences in pursuit gain arising from differences in optic flow strength in the stimulus reconcile much of the controversy on this topic.

  20. Particle Swarm Optimization for Outdoor Lighting Design

    Directory of Open Access Journals (Sweden)

    Ana Castillo-Martinez


    Full Text Available Outdoor lighting is an essential service for modern life. However, the high influence of this type of facility on energy consumption makes it necessary to take extra care in the design phase. Therefore, this manuscript describes an algorithm to help light designers to get, in an easy way, the best configuration parameters and to improve energy efficiency, while ensuring a minimum level of overall uniformity. To make this possible, we used a particle swarm optimization (PSO algorithm. These algorithms are well established, and are simple and effective to solve optimization problems. To take into account the most influential parameters on lighting and energy efficiency, 500 simulations were performed using DIALux software (, DIAL, Ludenscheid, Germany. Next, the relation between these parameters was studied using to data mining software. Subsequently, we conducted two experiments for setting parameters that enabled the best configuration algorithm in order to improve efficiency in the proposed process optimization.

  1. Outdoor air pollution and sperm quality. (United States)

    Lafuente, Rafael; García-Blàquez, Núria; Jacquemin, Bénédicte; Checa, Miguel Angel


    Exposure to air pollution has been clearly associated with a range of adverse health effects, including reproductive toxicity, but its effects on male semen quality are still unclear. We performed a systematic review (up to June 2016) to assess the impact of air pollutants on sperm quality. We included 17 semi-ecological, panel, and cohort studies, assessing outdoor air pollutants, such as PM2.5, PM10, NOx, SO2, and O3, and their effects on DNA fragmentation, sperm count, sperm motility, and sperm morphology. Thirteen studies assessed air pollution exposure measured environmentally, and six used biomarkers of air pollution exposure (two did both). We rated the studies using the Newcastle-Ottawa Scale and assessed with the exposure method. Taking into account these factors and the number of studies finding significant results (positive or negative), the evidence supporting an effect of air pollution on DNA fragmentation is weak but suggestive, on sperm motility is limited and probably inexistent, on lower sperm count is inconclusive, and on sperm morphology is very suggestive. Because of the diversity of air pollutants and sperm parameters, and the studies' designs, we were unable to perform a meta-analysis. In summary, most studies concluded that outdoor air pollution affects at least one of the four semen quality parameters included in the review. However, results lack consistency, and furthermore, studies were not comparable. Studies using standardized air pollution and semen measures are required to obtain more reliable conclusions.

  2. Let's Walk Outdoors! Self-Paced Walking Outdoors Improves Future Intention to Exercise in Women With Obesity. (United States)

    Krinski, Kleverton; Machado, Daniel G S; Lirani, Luciana S; DaSilva, Sergio G; Costa, Eduardo C; Hardcastle, Sarah J; Elsangedy, Hassan M


    In order to examine whether environmental settings influence psychological and physiological responses of women with obesity during self-paced walking, 38 women performed two exercise sessions (treadmill and outdoors) for 30 min, where oxygen uptake, heart rate, ratings of perceived exertion, affect, attentional focus, enjoyment, and future intentions to walk were analyzed. Physiological responses were similar during both sessions. However, during outdoor exercise, participants displayed higher externally focused attention, positive affect, and lower ratings of perceived exertion, followed by greater enjoyment and future intention to participate in outdoor walking. The more externally focused attention predicted greater future intentions to participate in walking. Therefore, women with obesity self-selected an appropriate exercise intensity to improve fitness and health in both environmental settings. Also, self-paced outdoor walking presented improved psychological responses. Health care professionals should consider promoting outdoor forms of exercise to maximize psychological benefits and promote long-term adherence to a physically active lifestyle.

  4. From risky behaviour to sexy adventures: reconceptualising young people's online sexual activities. (United States)

    Naezer, Marijke


    Western discourses about young people and sexuality centre around the concept of risk. Anxieties have been fuelled by the increasing popularity of social media and practices such as 'sexting' and watching 'sexually explicit' materials online. Research has shown however that such risk discourses mainly serve to moralise about, pathologise and police particular behaviours and children. In order to counter such paternalism, researchers advocated a reconceptualisation of youth not as passive victims, but as active agents who actively negotiate sexual experiences and discourses. In this paper, which is based on ethnographic fieldwork among young people in The Netherlands, I argue that we need a reconceptualisation not only of youth, but also of their sexual practices, especially their online sexual practices. Mobilising an interdisciplinary interaction between critical socio-cultural studies of risk, feminist theory and adventure studies, I propose to reconceptualise these practices as 'adventures' rather than 'risky behaviour'. This opens up possibilities for a more reasoned analysis that acknowledges: (1) the distinction between risks and outcomes of an activity; (2) the constructive potential of risk; and (3) the subjective, dynamic character of risk and pleasure.

  5. Simple Motion Pursuit and Evasion Differential Games with Many Pursuers on Manifolds with Euclidean Metric

    Directory of Open Access Journals (Sweden)

    Atamurat Kuchkarov


    Full Text Available We consider pursuit and evasion differential games of a group of m pursuers and one evader on manifolds with Euclidean metric. The motions of all players are simple, and maximal speeds of all players are equal. If the state of a pursuer coincides with that of the evader at some time, we say that pursuit is completed. We establish that each of the differential games (pursuit or evasion is equivalent to a differential game of m groups of countably many pursuers and one group of countably many evaders in Euclidean space. All the players in any of these groups are controlled by one controlled parameter. We find a condition under which pursuit can be completed, and if this condition is not satisfied, then evasion is possible. We construct strategies for the pursuers in pursuit game which ensure completion the game for a finite time and give a formula for this time. In the case of evasion game, we construct a strategy for the evader.

  6. A Pursuit Theory Account for the Perception of Common Motion in Motion Parallax. (United States)

    Ratzlaff, Michael; Nawrot, Mark


    The visual system uses an extraretinal pursuit eye movement signal to disambiguate the perception of depth from motion parallax. Visual motion in the same direction as the pursuit is perceived nearer in depth while visual motion in the opposite direction as pursuit is perceived farther in depth. This explanation of depth sign applies to either an allocentric frame of reference centered on the fixation point or an egocentric frame of reference centered on the observer. A related problem is that of depth order when two stimuli have a common direction of motion. The first psychophysical study determined whether perception of egocentric depth order is adequately explained by a model employing an allocentric framework, especially when the motion parallax stimuli have common rather than divergent motion. A second study determined whether a reversal in perceived depth order, produced by a reduction in pursuit velocity, is also explained by this model employing this allocentric framework. The results show than an allocentric model can explain both the egocentric perception of depth order with common motion and the perceptual depth order reversal created by a reduction in pursuit velocity. We conclude that an egocentric model is not the only explanation for perceived depth order in these common motion conditions. © The Author(s) 2016.

  7. Contrast and assimilation in motion perception and smooth pursuit eye movements. (United States)

    Spering, Miriam; Gegenfurtner, Karl R


    The analysis of visual motion serves many different functions ranging from object motion perception to the control of self-motion. The perception of visual motion and the oculomotor tracking of a moving object are known to be closely related and are assumed to be controlled by shared brain areas. We compared perceived velocity and the velocity of smooth pursuit eye movements in human observers in a paradigm that required the segmentation of target object motion from context motion. In each trial, a pursuit target and a visual context were independently perturbed simultaneously to briefly increase or decrease in speed. Observers had to accurately track the target and estimate target speed during the perturbation interval. Here we show that the same motion signals are processed in fundamentally different ways for perception and steady-state smooth pursuit eye movements. For the computation of perceived velocity, motion of the context was subtracted from target motion (motion contrast), whereas pursuit velocity was determined by the motion average (motion assimilation). We conclude that the human motion system uses these computations to optimally accomplish different functions: image segmentation for object motion perception and velocity estimation for the control of smooth pursuit eye movements.

  11. R.L. Stevenson's 'Most Grim and Gloomy Tale': The Ebb-Tide as Deconstruction of Colonial Adventure Narrative

    Directory of Open Access Journals (Sweden)

    Christy Danelle Di Frances


    Full Text Available Although Edinburgh-born author Robert Louis Stevenson is best known as a writer of nineteenth-century popular adventures, his work to a great extent challenges prevailing adventure ideology of the Victorian era. This paper focuses on Stevenson's complexification of the villain trope in The Ebb-Tide, a South Seas novella published only a few months before his death in 1894. In the text, Stevenson blatantly disregards or dismantles typical colonial presentations of a simplistic villain personified through such topoi as the 'demonic male', the violent-but-beautiful female savage, or the vaguely formidable Other - all of which frequently populate adventure's exotic realm in nineteenth-century fiction. Rather than relying upon these culturally codified depictions, in The Ebb-Tide Stevenson presents villainy as embodied by a dangerous amalgamation of ordinary vice and extraordinary evil that traverses those national and ethnic boundaries that colonialism so often sought to demarcate and solidify. The portrayal of villainy within this text culminates in a nightmarish atmosphere which, in Stevenson's fiction, inevitably results from the unchecked workings of personal transgressions combined with a larger and more powerful indicator of evil. In so doing, the author succeeds in creating a dark narrative latent with culturally relevant commentary which, in turn, contributes to his broader re-navigation of an ethically-charged aesthetics of adventure for a modern audience.

  15. Normal aging affects movement execution but not visual motion working memory and decision-making delay during cue-dependent memory-based smooth-pursuit. (United States)

    Fukushima, Kikuro; Barnes, Graham R; Ito, Norie; Olley, Peter M; Warabi, Tateo


    Aging affects virtually all functions including sensory/motor and cognitive activities. While retinal image motion is the primary input for smooth-pursuit, its efficiency/accuracy depends on cognitive processes. Elderly subjects exhibit gain decrease during initial and steady-state pursuit, but reports on latencies are conflicting. Using a cue-dependent memory-based smooth-pursuit task, we identified important extra-retinal mechanisms for initial pursuit in young adults including cue information priming and extra-retinal drive components (Ito et al. in Exp Brain Res 229:23-35, 2013). We examined aging effects on parameters for smooth-pursuit using the same tasks. Elderly subjects were tested during three task conditions as previously described: memory-based pursuit, simple ramp-pursuit just to follow motion of a single spot, and popping-out of the correct spot during memory-based pursuit to enhance retinal image motion. Simple ramp-pursuit was used as a task that did not require visual motion working memory. To clarify aging effects, we then compared the results with the previous young subject data. During memory-based pursuit, elderly subjects exhibited normal working memory of cue information. Most movement-parameters including pursuit latencies differed significantly between memory-based pursuit and simple ramp-pursuit and also between young and elderly subjects. Popping-out of the correct spot motion was ineffective for enhancing initial pursuit in elderly subjects. However, the latency difference between memory-based pursuit and simple ramp-pursuit in individual subjects, which includes decision-making delay in the memory task, was similar between the two groups. Our results suggest that smooth-pursuit latencies depend on task conditions and that, although the extra-retinal mechanisms were functional for initial pursuit in elderly subjects, they were less effective.

    Full Text Available Current study aims to identify activity areas of mountaineering and outdoor sports clubs in Turkey that organize activities regularly. Universe of the study was composed of mountaineering and outdoor sports clubs that were active between the dates of 11 March 2012 and 5 January 2013. This study and the sample included 49 active outdoor sports clubs that could be reached in the region. Data were collected via surveys. Obtained data were analyzed and interpreted with the help of statistical package program (SPSS 16.0. Frequencies and percentage distributions were provided. Criteria for the provision of outdoor sports activities in clubs include requests from members and geographical conditions of the area. It is observed that those clubs provide outdoor walks approximately for 21-40 members. There are clubs without trainers. Clubs provide mountaineering and rock climbing activities the most. Aegean and Marmara Regions are more active compared to other regions. In general, most of the clubs are active in areas such as mountaineering, rock climbing and outdoor walks. It is suggested that local administrations and federations support outdoor sports clubs

  17. A Model of the Smooth Pursuit Eye Movement with Prediction and Learning

    Directory of Open Access Journals (Sweden)

    Davide Zambrano


    Full Text Available Smooth pursuit is one of the five main eye movements in humans, consisting of tracking a steadily moving visual target. Smooth pursuit is a good example of a sensory-motor task that is deeply based on prediction: tracking a visual target is not possible by correcting the error between the eye and the target position or velocity with a feedback loop, but it is only possible by predicting the trajectory of the target. This paper presents a model of smooth pursuit based on prediction and learning. It starts from amodel of the neuro-physiological system proposed by Shibata and Schaal (Shibata et al., Neural Networks, vol. 18, pp. 213-224, 2005. The learning component added here decreases the prediction time in the case of target dynamics already experienced by the system. In the implementation described here, the convergence time is, after the learning phase, 0.8 s.

    KAUST Repository

    Ali, Hussain El Hosiny


    Multiple-input multiple-output (MIMO) radar works on the principle of transmission of independent waveforms at each element of its antenna array and is widely used for surveillance purposes. In this work, we investigate MIMO radar target localization problem with compressive sensing. Specifically, we try to solve the problem of estimation of target location in MIMO radar by group and block sparsity algorithms. It will lead us to a reduced number of snapshots required and also we can achieve better radar resolution. We will use group orthogonal matching pursuit (GOMP) and block orthogonal matching pursuit (BOMP) for our problem. © 2014 IEEE.

    Mårtensson, F; Boldemann, C; Söderström, M; Blennow, M; Englund, J-E; Grahn, P


    The restorative potential of green outdoor environments for children in preschool settings was investigated by measuring the attention of children playing in settings with different environmental features. Eleven preschools with outdoor environments typical for the Stockholm area were assessed using the outdoor play environment categories (OPEC) and the fraction of visible sky from play structures (sky view factor), and 198 children, aged 4.5-6.5 years, were rated by the staff for inattentive, hyperactive and impulsive behaviors with the ECADDES tool. Children playing in large and integrated outdoor areas containing large areas of trees, shrubbery and a hilly terrain showed less often behaviors of inattention (pOPEC can be useful when to locate and develop health-promoting land adjacent to preschools.

  5. Language Learning in Outdoor Environments: Perspectives of preschool staff

    Directory of Open Access Journals (Sweden)

    Martina Norling


    Full Text Available Language environment is highlighted as an important area in the early childhood education sector. The term language environment refers to language-promoting aspects of education, such as preschool staff’s use of verbal language in interacting with the children. There is a lack of research about language learning in outdoor environments; thus children’s language learning is mostly based on the indoor physical environment. The aim of this study is therefore to explore, analyse, and describe how preschool staff perceive language learning in outdoor environments. The data consists of focus-group interviews with 165 preschool staff members, conducted in three cities in Sweden. The study is meaningful, thus results contribute knowledge regarding preschool staffs’ understandings of language learning in outdoor environments and develop insights to help preschool staff stimulate children’s language learning in outdoor environments.

  7. Smart sensor systems for outdoor intrusion detection

    International Nuclear Information System (INIS)

    Lynn, J.K.


    A major improvement in outdoor perimeter security system probability of detection (PD) and reduction in false alarm rate (FAR) and nuisance alarm rate (NAR) may be obtained by analyzing the indications immediately preceding an event which might be interpreted as an intrusion. Existing systems go into alarm after crossing a threshold. Very slow changes, which accumulate until the threshold is reached, may be assessed falsely as an intrusion. A hierarchial program has begun at Stellar to develop a modular, expandable Smart Sensor system which may be interfaced to most types of sensor and alarm reporting systems. A major upgrade to the SSI Test Site is in progress so that intrusions may be simulated in a controlled and repeatable manner. A test platform is being constructed which will operate in conduction with a mobile instrumentation center with CCTVB, lighting control, weather and data monitoring and remote control of the test platform and intrusion simulators. Additional testing was contracted with an independent test facility to assess the effects of severe winter weather conditions

  9. Research trends in outdoor pig production — A review

    Directory of Open Access Journals (Sweden)

    Hyun-Suk Park


    Full Text Available Since the industrialization of swine production in the late 1900s, swine farms in the United States, as well as in Europe, have largely become consolidated. Pig farms became larger in size but fewer in number, with 91% of market pigs being produced by large operations with 5,000 or more pigs on-site in the US, and only 3% of the total utilized agricultural land representing organic farming. Such change in the market made it difficult for small farmers to stay competitive, forcing them to find alternative ways to reduce the cost of production and increase profit using the outdoor production system. In contrast to the indoor confinement system, outdoor production system uses pasture-based units and/or deep-bedded hoop structures that promote animal welfare and environmental sustainability with a lower capital investment. In accord with the growing concern for animal and environmental welfare and food safety by the consumers, small farmers practicing an outdoor production system are seeing increased opportunities for marketing their products in the pork niche market. Unlike the general belief that the reproductive and growth performance measures of the outdoor sows and piglets are poorer in comparison with the animals reared indoors, studies showed that there was no significant difference in the performance measures, and some traits were even better in outdoor animals. Improved reproductive and production traits can increase the sustainability of outdoor farming. Present study reviewed the recent studies comparing the performance measures, meat quality and health of indoor and outdoor animals, as well as the efforts to improve the outdoor production system through changes in management such as hut types and breed of animals.

  10. Characteristics of outdoor falls among older people: a qualitative study. (United States)

    Nyman, Samuel R; Ballinger, Claire; Phillips, Judith E; Newton, Rita


    Falls are a major threat to older people's health and wellbeing. Approximately half of falls occur in outdoor environments but little is known about the circumstances in which they occur. We conducted a qualitative study to explore older people's experiences of outdoor falls to develop understanding of how they may be prevented. We conducted nine focus groups across the UK (England, Wales, and Scotland). Our sample was from urban and rural settings and different environmental landscapes. Participants were aged 65+ and had at least one outdoor fall in the past year. We analysed the data using framework and content analyses. Forty-four adults aged 65 - 92 took part and reported their experience of 88 outdoor falls. Outdoor falls occurred in a variety of contexts, though reports suggested the following scenarios may have been more frequent: when crossing a road, in a familiar area, when bystanders were around, and with an unreported or unknown attribution. Most frequently, falls resulted in either minor or moderate injury, feeling embarrassed at the time of the fall, and anxiety about falling again. Ten falls resulted in fracture, but no strong pattern emerged in regard to the contexts of these falls. Anxiety about falling again appeared more prevalent among those that fell in urban settings and who made more visits into their neighbourhood in a typical week. This exploratory study has highlighted several aspects of the outdoor environment that may represent risk factors for outdoor falls and associated fear of falling. Health professionals are recommended to consider outdoor environments as well as the home setting when working to prevent falls and increase mobility among older people.

    Francesco-Alessio Ursini


    Full Text Available This article analyses the influence of David Bowie’s work in JoJo’s Bizarre Adventure, a manga known for its wealth of references to western popular culture. It is argued that David Bowie’s cultural reception can be attested via the presence of three narrative themes featuring in this manga series. The first theme is the exploration of diverse genres and an innovative, genre-defying attitude. The second theme is the use of avant-garde, flamboyant and gender-ambiguous aesthetics for its fictional characters. The third theme is a self-reflexive approach to the creation of fictional characters, intended as an awareness of the temporary, transient nature of their role as reluctant heroes in their own stories.

  15. CFD Analysis of Square Flow Channel in Thermal Engine Rocket Adventurer for Space Nuclear Application

    International Nuclear Information System (INIS)

    Nam, S. H.; Suh, K. Y.; Kang, S. G.


    Solar system exploration relying on chemical rockets suffers from long trip time and high cost. In this regard nuclear propulsion is an attractive option for space exploration. The performance of Nuclear Thermal Rocket (NTR) is more than twice that of the best chemical rocket. Resorting to the pure hydrogen (H 2 ) propellant the NTRs can possibly achieve as high as 1,000 s of specific impulse (I sp ) representing the ratio of the thrust over the fuel consumption rate, as compared to only 425 s of H 2 /O 2 rockets. If we reflect on the mission to Mars, NTRs would reduce the round trip time to less than 300 days, instead of over 600 days with chemical rockets. This work presents CFD analysis of one Fuel Element (FE) of Thermal Engine Rocket Adventurer (TERA). In particular, one Square Flow Channel (SFC) is analyzed in Square Lattice Honeycomb (SLHC) fuel to examine the effects of mass flow rate on rocket performance

  17. Outbreak of Rickettsia africae infections in participants of an adventure race in South Africa. (United States)

    Fournier, P E; Roux, V; Caumes, E; Donzel, M; Raoult, D


    African tick-bite fever, caused by Rickettsia africae and transmitted by Amblyomma ticks, is an emerging rickettsiosis in southern Africa. Because of increased tourism to this area, several cases in tourists have been reported recently. We report 13 cases of R. africae infection diagnosed in France that occurred in competitors returning from an adventure race in South Africa and compare our data with previously reported findings. Most of our patients presented with fever, headache, multiple inoculation eschars, and regional lymphadenopathies, but only 15.4% had a cutaneous rash. Diagnosis was confirmed either by isolation of R. africae from an eschar biopsy specimen or by serological methods, including cross-adsorption between R. africae and Rickettsia conorii. The purpose of this study was to raise physicians' awareness of R. africae infections in an attempt to facilitate the rapid diagnosis and treatment of imported African tick-bite fever in developed countries.

    Full Text Available Lewis Carroll’s Alice’s Adventures in Wonderland (1865 is a text rich of cultural and literary references to Victorian England. This feature is one of the major obstacles to translating this work since the transfer of cultural markers from source to target text often produces partial or total loss of certain nuances of meaning. The purpose of this paper is to analyze the Russian translations of Alice through a comparative study of three translation specimens (Nabokov 1923; Olenič-Gnenenko 1940; Demurova 1967, 1978, which constitute just as many methods (domestication, foreignization, hybridization. Through the study of some difficult cases of translation – proper names with culture-specific connotations, puns and parodies – I will highlight the specificities of these different versions to understand whether and how the translator’s choices have affected the reception of Wonderland in Russia.

  20. Realistic Real-Time Outdoor Rendering in Augmented Reality (United States)

    Kolivand, Hoshang; Sunar, Mohd Shahrizal


    Realistic rendering techniques of outdoor Augmented Reality (AR) has been an attractive topic since the last two decades considering the sizeable amount of publications in computer graphics. Realistic virtual objects in outdoor rendering AR systems require sophisticated effects such as: shadows, daylight and interactions between sky colours and virtual as well as real objects. A few realistic rendering techniques have been designed to overcome this obstacle, most of which are related to non real-time rendering. However, the problem still remains, especially in outdoor rendering. This paper proposed a much newer, unique technique to achieve realistic real-time outdoor rendering, while taking into account the interaction between sky colours and objects in AR systems with respect to shadows in any specific location, date and time. This approach involves three main phases, which cover different outdoor AR rendering requirements. Firstly, sky colour was generated with respect to the position of the sun. Second step involves the shadow generation algorithm, Z-Partitioning: Gaussian and Fog Shadow Maps (Z-GaF Shadow Maps). Lastly, a technique to integrate sky colours and shadows through its effects on virtual objects in the AR system, is introduced. The experimental results reveal that the proposed technique has significantly improved the realism of real-time outdoor AR rendering, thus solving the problem of realistic AR systems. PMID:25268480
