The National Park System covers more than 84 million acres and is comprised of more than 401 sites across the Nation. These lands managed by the National Park Service (NPS) serve as recreational destinations for visitors from across the Nation and around the world. On vacations or on day trips, NPS visitors spend time and money in the gateway communities surrounding NPS sites. Spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway economies. The NPS has been measuring and reporting visitor spending and economic effects for the past 25 years. The 2012 analysis marked a major revision to the NPS visitor spending effects analyses, with the development of the Visitor Spending Effects model (VSE model) which replaced the previous Money Generation Model (see Cullinane Thomas et al. (2014) for a description of how the VSE model differs from the previous model). This report provides updated VSE estimates associated with 2014 NPS visitation.

Motivations for recreating on farmlands, private forests, and state or national parks.
Sotomayor, Sandra; Barbieri, Carla; Wilhelm Stanis, Sonja; Aguilar, Francisco X; Smith, Jordan W
2014-07-01
This study explores the importance of different motivations to visit three types of recreational settings--farms, private forests, and state or national parks. Data were collected via a mail-back questionnaire administered to a stratified random sample of households in Missouri (USA). Descriptive and inferential statistics reveal both similarities and discontinuities in motivations for visiting farms, private forests, and state or national parks for recreation. Being with family, viewing natural scenery, and enjoying the smells and sounds of nature were all highly important motivations for visiting the three types of settings. However, all 15 motivations examined were perceived to be significantly more important for visits to state or national parks than to farms or private forests. Findings suggest that individuals are more strongly motivated to recreate at state and national parks relative to farmlands or forests. Post hoc paired t tests comparing motivations between both agricultural settings (farms and private forests) revealed significant differences in eight different recreational motivations. Individuals tended to place more importance on the ability to use equipment and test their skills when considering recreating on private forests. Conversely, social motivations (e.g., doing something with the family) were more important when individuals were considering recreating on farmland. Collectively, the findings suggest individuals expect distinctly different outcomes from their visits to farmlands, private forests, or state or national parks. Consequently, all three types of recreational settings have competitive advantages that their managers could capitalize on when making decisions about how to attract new visitors or produce the most desirable experiences for current recreationists.

GATEWAY - COMMUNICATIONS GATEWAY SOFTWARE FOR NETEX, DECNET, AND TCP/IP
Keith, B.
1994-01-01
The Communications Gateway Software, GATEWAY, provides process-to-process communication between remote applications programs in different protocol domains. Communicating peer processes may be resident on any paired combination of NETEX, DECnet, or TCP/IP hosts. The gateway provides the necessary mapping from one protocol to another and will facilitate practical intermachine communications in a cost effective manner by eliminating the need to standardize on a single protocol or the need to implement multiple protocols in the host computers. The purpose of the gateway is to support data transfers between application programs on different host computers using different protocols. The gateway computer must be physically connected to both host computers and must contain the system software needed to use the communication protocols of both host computers. The communication process between application partners can be divided into three phases: session establishment, data transfer, and session termination. The communication protocols supported by GATEWAY (DECnet, NETEX, and TCP/IP) have addressing mechanisms that allow an application to identify itself and distinguish among other applications on the network. The exact form of the address varies depending on whether an application is passively offering (awaiting the receipt of a network connection from another network application) or actively connecting to another network. When the gateway is started, GATEWAY reads a file of address pairs. One of the address pairs is used by GATEWAY for passively offering on one network while the other address in the pair is used for actively connecting on the other network establishing the session. Now the two application partners can send and receive data in a manner appropriate to their home networks. GATEWAY accommodates full duplex transmissions. Thus, if the application partners are sophisticated enough, they can send and receive simultaneously. GATEWAY also keeps track of the number

The unique contributions of the Neutron Science TeraGrid Gateway (NSTG) are the connection of national user facility instrument data sources to the integrated cyberinfrastructure of the National Science FoundationTeraGrid and the development of a neutron science gateway that allows neutron scientists to use TeraGrid resources to analyze their data, including comparison of experiment with simulation. The NSTG is working in close collaboration with the Spallation Neutron Source (SNS) at Oak Ridge as their principal facility partner. The SNS is a next-generation neutron source. It has completed construction at a cost of $1.4 billion and is ramping up operations. The SNS will provide an order of magnitude greater flux than any previous facility in the world and will be available to all of the nation's scientists, independent of funding source, on a peer-reviewed merit basis. With this new capability, the neutron science community is facing orders of magnitude larger data sets and is at a critical point for data analysis and simulation. There is a recognized need for new ways to manage and analyze data to optimize both beam time and scientific output. The TeraGrid is providing new capabilities in the gateway for simulations using McStas and a fitting service on distributed TeraGrid resources to improved turnaround. NSTG staff are also exploring replicating experimental data in archival storage. As part of the SNS partnership, the NSTG provides access to gateway support, cyberinfrastructure outreach, community development, and user support for the neutron science community. This community includes not only SNS staff and users but extends to all the major worldwide neutron scattering centers.

The National Science Foundation's (NSF's) Extensible Terascale Facility (ETF), or TeraGrid (1) is entering its operational phase. An ETF science gateway effort is the Neutron Science TeraGrid Gateway (NSTG.) The Oak Ridge National Laboratory (ORNL) resource provider effort (ORNL-RP) during construction and now in operations is bridging a large scale experimental community and the TeraGrid as a large-scale national cyberinfrastructure. Of particular emphasis is collaboration with the Spallation Neutron Source (SNS) at ORNL. The U.S. Department of Energy's (DOE's) SNS (2) at ORNL will be commissioned in spring of 2006 as the world's brightest source of neutrons. Neutron science users can run experiments, generate datasets, perform data reduction, analysis, visualize results; collaborate with remotes users; and archive long term data in repositories with curation services. The ORNL-RP and the SNS data analysis group have spent 18 months developing and exploring user requirements, including the creation of prototypical services such as facility portal, data, and application execution services. We describe results from these efforts and discuss implications for science gateway creation. Finally, we show incorporation into implementation planning for the NSTG and SNS architectures. The plan is for a primarily portal-based user interaction supported by a service oriented architecture for functional implementation

Mentoring the Next Generation of Science Gateway Developers and Users
Hayden, L. B.; Jackson-Ward, F.
2016-12-01
The Science Gateway Institute (SGW-I) for the Democratization and Acceleration of Science was a SI2-SSE Collaborative Research conceptualization award funded by NSF in 2012. From 2012 through 2015, we engaged interested members of the science and engineering community in a planning process for a Science Gateway Community Institute (SGCI). Science Gateways provide Web interfaces to some of the most sophisticated cyberinfrastructure resources. They interact with remotely executing science applications on supercomputers, they connect to remote scientific data collections, instruments and sensor streams, and support large collaborations. Gateways allow scientists to concentrate on the most challenging science problems while underlying components such as computing architectures and interfaces to data collection changes. The goal of our institute was to provide coordinating activities across the National Science Foundation, eventually providing services more broadly to projects funded by other agencies. SGW-I has succeeded in identifying two underrepresented communities of future gateway designers and users. The Association of Computer and Information Science/Engineering Departments at Minority Institutions (ADMI) was identified as a source of future gateway designers. The National Organization for the Professional Advancement of Black Chemists and Chemical Engineers (NOBCChE) was identified as a community of future science gateway users. SGW-I efforts to engage NOBCChE and ADMI faculty and students in SGW-I are now woven into the workforce development component of SGCI. SGCI (ScienceGateways.org ) is a collaboration of six universities, led by San Diego Supercomputer Center. The workforce development component is led by Elizabeth City State University (ECSU). ECSU efforts focus is on: Produce a model of engagement; Integration of research into education; and Mentoring of students while aggressively addressing diversity.

Full Text Available Protected areas and national parks are becoming one of the most important forms of land use in Central America. All the projections made by the World Tourism Organization seems to agree that by 2010 Central America, maybe receiving between eight and ten millions tourists, a figure that is almost twice what the region is receiving today. A study was conducted base on 369 direct field surveys conducted in three Central American communities: Bagazit gateway community to Palo Verde National Park, Costa Rica, Nindiri, gateway community to Volcan Masaya National Park, Nicaragua and Portobelo, gateway community to Por-tobelo National Park, Panama. The study found that relative to the socio-demographic variables, that there were no significance differences at the 95% probability level in all four variables, age, sex, education and monthly income of the family. Educational level seems to be the socio-demographic variables affecting more the state of relations. The perception variable being has taken into account in the decision that affects the communities and responsibility to help with community problems are present in two of the three models. The perception variables related to tourism, feel trained to take care of the tourist and existence of businesses that can caters to tourist seem to be key elements in the community perception about the state of relation. Tourism related economic activities and community participation in park decisions are today and will be in the future essential elements in the shaping of community/park relations in Central America as tourism becomes a major economic sector in the region economy.

Water Quality Conditions Associated with Cattle Grazing and Recreation on National Forest Lands.
Directory of Open Access Journals (Sweden)
Leslie M Roche
Full Text Available There is substantial concern that microbial and nutrient pollution by cattle on public lands degrades water quality, threatening human and ecological health. Given the importance of clean water on multiple-use landscapes, additional research is required to document and examine potential water quality issues across common resource use activities. During the 2011 grazing-recreation season, we conducted a cross sectional survey of water quality conditions associated with cattle grazing and/or recreation on 12 public lands grazing allotments in California. Our specific study objectives were to 1 quantify fecal indicator bacteria (FIB; fecal coliform and E. coli, total nitrogen, nitrate, ammonium, total phosphorus, and soluble-reactive phosphorus concentrations in surface waters; 2 compare results to a water quality regulatory benchmarks, b recommended maximum nutrient concentrations, and c estimates of nutrient background concentrations; and 3 examine relationships between water quality, environmental conditions, cattle grazing, and recreation. Nutrient concentrations observed throughout the grazing-recreation season were at least one order of magnitude below levels of ecological concern, and were similar to U.S. Environmental Protection Agency (USEPA estimates for background water quality conditions in the region. The relative percentage of FIB regulatory benchmark exceedances widely varied under individual regional and national water quality standards. Relative to USEPA's national E. coli FIB benchmarks-the most contemporary and relevant standards for this study-over 90% of the 743 samples collected were below recommended criteria values. FIB concentrations were significantly greater when stream flow was low or stagnant, water was turbid, and when cattle were actively observed at sampling. Recreation sites had the lowest mean FIB, total nitrogen, and soluble-reactive phosphorus concentrations, and there were no significant differences in FIB and

Ad Hoc Access Gateway Selection Algorithm
Jie, Liu
With the continuous development of mobile communication technology, Ad Hoc access network has become a hot research, Ad Hoc access network nodes can be used to expand capacity of multi-hop communication range of mobile communication system, even business adjacent to the community, improve edge data rates. For mobile nodes in Ad Hoc network to internet, internet communications in the peer nodes must be achieved through the gateway. Therefore, the key Ad Hoc Access Networks will focus on the discovery gateway, as well as gateway selection in the case of multi-gateway and handover problems between different gateways. This paper considers the mobile node and the gateway, based on the average number of hops from an average access time and the stability of routes, improved gateway selection algorithm were proposed. An improved gateway selection algorithm, which mainly considers the algorithm can improve the access time of Ad Hoc nodes and the continuity of communication between the gateways, were proposed. This can improve the quality of communication across the network.

Scott, D; Jones, B. [Waterloo Univ., ON (Canada). Faculty of Environmental Studies; Khaled, H.A. [National Capital Commission, Ottawa, ON (Canada)
2005-03-15
The potential impact of climate change on recreation and tourism in Canada's National Capital Region was assessed. The objectives of the study were to examine two important issues, including how climate change will influence the seasonality of major recreation and tourism segments in the winter and summer months. The study analysed the disparate vulnerability of recreation and tourism segments to climate variability and change, explored risks and opportunities for recreation and tourism in the region, and examined management adaptation strategies. The study was conducted in several phases involving consultation meetings with National Capital Commission staff, data compilation and development of climate change scenarios. This was followed by a climate change impact assessment. The report also provided information on the methodology used for the study and on climate change impact indicators. It was concluded that as a result of climate change, the Winterlude season would become shorter and that the timeframe for skating on the Rideau Canal was projected to be shortened. 61 refs., 23 tabs., 20 figs., 2 appendices.

Using Count Data and Ordered Models in National Forest Recreation Demand Analysis
Simões, Paula; Barata, Eduardo; Cruz, Luis
2013-11-01
This research addresses the need to improve our knowledge on the demand for national forests for recreation and offers an in-depth data analysis supported by the complementary use of count data and ordered models. From a policy-making perspective, while count data models enable the estimation of monetary welfare measures, ordered models allow for the wider use of the database and provide a more flexible analysis of data. The main purpose of this article is to analyse the individual forest recreation demand and to derive a measure of its current use value. To allow a more complete analysis of the forest recreation demand structure the econometric approach supplements the use of count data models with ordered category models using data obtained by means of an on-site survey in the Bussaco National Forest (Portugal). Overall, both models reveal that travel cost and substitute prices are important explanatory variables, visits are a normal good and demographic variables seem to have no influence on demand. In particular, estimated price and income elasticities of demand are quite low. Accordingly, it is possible to argue that travel cost (price) in isolation may be expected to have a low impact on visitation levels.

Cannabis has been legalized for medical use in almost half of the states in the U.S. Although laws in these states make the distinction between medical and recreational use of cannabis, the prevalence of people using medical cannabis and how distinct this group is from individuals using cannabis recreationally is unknown at a national level. Data came from the 2013 National Survey on Drug Use and Health (NSDUH). All adults endorsing past year cannabis use who reported living in a state that had legalized medical cannabis were divided into recreational cannabis use only and medical cannabis use. Demographic and clinical characteristics were compared across these two groups. 17% of adults who used cannabis in the past year used cannabis medically. There were no significant differences between those who used medically versus recreationally in race, education, past year depression and prevalence of cannabis use disorders. In adjusted analyses, those with medical cannabis use were more likely to have poorer health and lower levels of alcohol use disorders and non-cannabis drug use. A third of those who reported medical cannabis use endorsed daily cannabis use compared to 11% in those who reported recreational use exclusively. Adults who use medical and recreational cannabis shared some characteristics, but those who used medical cannabis had higher prevalence of poor health and daily cannabis use. As more states legalize cannabis for medical use, it is important to better understand similarities and differences between people who use cannabis medically and recreationally.

Estimating the recreational-use value for hiking in Bellenden Ker National Park, Australia.
Nillesen, Eleonora; Wesseler, Justus; Cook, Averil
2005-08-01
The recreational-use value of hiking in the Bellenden Ker National Park, Australia has been estimated using a zonal travel cost model. Multiple destination visitors have been accounted for by converting visitors' own ordinal ranking of the various sites visited to numerical weights, using an expected-value approach. The value of hiking and camping in this national park was found to be dollar AUS 250,825 per year, or dollar AUS 144,45 per visitor per year, which is similar to findings from other studies valuing recreational benefits. The management of the park can use these estimates when considering the introduction of a system of user pays fees. In addition, they might be important when decisions need to be made about the allocation of resources for maintenance or upgrade of tracks and facilities.

The EPICS process variable Gateway Version 2
International Nuclear Information System (INIS)
Evans, K.
2005-01-01
The EPICS Process Variable Gateway is both a Channel Access Server and Channel Access Client that provides a means for many clients, typically on different subnets, to access a process variable while making only one connection to the server that owns the process variable. It also provides additional access security beyond that implemented on the server. It thus protects critical servers while providing suitably restricted access to needed process variables. The original version of the Gateway worked with EPICS Base 3.13 but required a special version, since the changes necessary for its operation were never incorporated into EPICS Base. Version 2 works with any standard EPICS Base 3.14.6 or later and has many improvements in both performance and features over the older version. The Gateway is now used at many institutions and has become a stable, high-performance application. It is capable of handling tens of thousands of process variables with hundreds of thousands of events per second. It has run for over three months in a production environment without having to be restarted. It has many internal process variables that can be used to monitor its state using standard EPICS client tools, such as MEDM and StripTool. Other internal process variables can be used to stop the Gateway, make several kinds of reports, or change the access security without stopping the Gateway. It can even be started on remote workstations from MEDM by using a Secure Shell script. This paper will describe the new Gateway and how it is used. The Gateway is both a server (like an EPICS Input/Output Controller (IOC)) and a client (like the EPICS Motif Editor and Display Manager (MEDM), StripTool, and others). Clients connect to the server side, and the client side connects to IOCs and other servers, possibly other Gateways. See Fig. 1. There are perhaps three principal reasons for using the Gateway: (1) it allows many clients to access a process variable while making only one connection to

Plant simulators using gateway devices
International Nuclear Information System (INIS)
Forbes, H.W.
1988-01-01
One of the most difficult tasks in building a full-scope power plant simulator is modelling the plant process computer. For reasons of cost, it is usually not feasible to include a duplicate process computer within the simulator, although this would provide the highest degree of realism. The recent introduction of gateway devices by several process control manufacturers changes the cost picture considerably. These gateways are capable of emulating Input/Output multiplexers and controllers at significantly less cost. Simulators which use these devices can provide the absolute realism of a duplicate process computer without the associated cost burden. This paper discusses the use of gateways in simulators, and examines the case of a simulator now being built which uses this design technique

A Gateway MultiSite recombination cloning toolkit.
Directory of Open Access Journals (Sweden)
Lena K Petersen
Full Text Available The generation of DNA constructs is often a rate-limiting step in conducting biological experiments. Recombination cloning of single DNA fragments using the Gateway system provided an advance over traditional restriction enzyme cloning due to increases in efficiency and reliability. Here we introduce a series of entry clones and a destination vector for use in two, three, and four fragment Gateway MultiSite recombination cloning whose advantages include increased flexibility and versatility. In contrast to Gateway single-fragment cloning approaches where variations are typically incorporated into model system-specific destination vectors, our Gateway MultiSite cloning strategy incorporates variations in easily generated entry clones that are model system-independent. In particular, we present entry clones containing insertions of GAL4, QF, UAS, QUAS, eGFP, and mCherry, among others, and demonstrate their in vivo functionality in Drosophila by using them to generate expression clones including GAL4 and QF drivers for various trp ion channel family members, UAS and QUAS excitatory and inhibitory light-gated ion channels, and QUAS red and green fluorescent synaptic vesicle markers. We thus establish a starter toolkit of modular Gateway MultiSite entry clones potentially adaptable to any model system. An inventory of entry clones and destination vectors for Gateway MultiSite cloning has also been established (www.gatewaymultisite.org.

Multi-Gateway-Based Energy Holes Avoidance Routing Protocol for WSN
Directory of Open Access Journals (Sweden)
Rohini Sharma
2016-04-01
Full Text Available In wireless sensor networks (WSNs, efficient energy conservation is required to prolong the lifetime of the network. In this work, we have given emphasis on balanced energy consumption and energy holes avoidance. This paper proposes a multi-gateway-based approach to reduce the transmission distance between the sender and the sink node. The area to be monitored is divided into regions and gateway nodes are deployed at optimal positions. We have designed a transmission scheme, in which sensors in the sink region communicate directly to the sink, sensors in the gateway region communicate directly to the gateway, and sensors in the cluster region transmit their data directly to their respective cluster head which transmits data to the gateway in its region. If the distance between a cluster head and the sink is less than the distance between the cluster head and the gateway node, the cluster head transmits data to the sink instead of the gateway node. We have compared the proposed protocol with Low-Energy Adaptive Clustering Hierarchy (LEACH, Gateway Based Energy Aware Multi-Hop Routing (M-GEAR, and Gateway Based Stable Election Protocol (GSEP protocols. The protocol performs better than other protocols in terms of throughput, stability period, lifetime, residual energy, and the packet transmitted to the sink.

2016-12-01
In this study we estimate selected visitors' demand and value for recreational trips to settings such as developed vs. undeveloped sites in U.S. national forests in the Southern United States using the travel cost method. The setting-based approach allows for valuation of multi-activity trips to particular settings. The results from an adjusted Poisson lognormal estimator corrected for truncation and endogenous stratification reveal that economic value per trip estimates are higher for wilderness compared to day-use developed settings, overnight-use developed settings, and general forest areas. Estimates of these economic values are important to resource managers because their management decisions and actions typically control recreational settings. For example, managers control developed campground capacity in a national forest, but typically not the number of campers below the capacity constraint and the number and types of activities visitors engage in during a multi-activity trip to a developed campground (within limits since some activities such as discharging a firearm are not permitted in a developed campground).

SEDAC information gateway plan V(1)
Chen, Robert S. (Compiler)
1995-01-01
This annual update of the Information Gateway Plan incorporates changes recommended by the Socioeconomic Data and Applications Center (SEDAC) User Working Group (UWG) and reflects comments and suggestions from users, collaborators, and the Contracting Officer Technical Representative (COTR). The Information Gateway Plan is a concise and specific plan that outlines SEDAC activities and services in support of the earth and social sciences and other user communities. The SEDAC Information Gateway effort is a primary means by which the Earth Observing System Data and Information System (EOSDIS) can link meaningfully with a broad range of social science data sources and users in ways that lead to tangible benefits to the American people. The SEDAC Information Gateway provides interdisciplinary access to socioeconomic and physical science data and information resources held by SEDAC and numerous other institutions and networks around the world. The Plan describes the areas of research of earth scientists and socioeconomic scientists where interchange of data and information is most needed. It sets guidelines for the continued development of SEDAC's directory of social science datasets and establishes priorities for efforts to make data held by SEDAC or accessible through SEDAC available to the user community. The Plan also describes the means by which the SEDAC user community can access information products specified by the SEDAC Data and Applications Development Plan (DADP). Among other major activities, SEDAC will continue to enhance and operate a directory capability, interoperable with the Global Change Master Directory, that provides the socioeconomic community with information about earth science products and the earth science research community with information about socioeconomic data. The Information Gateway also serves as a unique and powerful access pathway for a wide range of users and potential users of socioeconomic and earth science data, including

One day in February 1991, a man strolling along a bucolic stretch of rural real estate in Alabama heard the call of what he later discovered to be a red-cockaded woodpecker. A rare event, this would ordinarily have been a pleasant surprise. When officials at the Federal Energy Regulatory Commission (FERC) in Washington, D.C., got word of the red's siting, they took notice. And when Dan Mitchell and Jamie Craddock at United Gas Pipe Line Co. in Houston found out, they just shook their heads --- again. The red-cockaded woodpecker is but one of the uniquely named, federally protected species native to South Alabama that Mitchell and Craddock had to constantly concern themselves with as they attempted to ensure the environmental and regulatory compliance of United's recently completed 28-mile Gateway gas pipeline near gas-rich Mobile Bay. Until May 1, when United put Gateway into service, it had taken more than six years to plan and construct the most environmentally correct route for the pipeline. This paper discusses the largest portion of Gateway's route which is piney forest or agricultural land with the wetlands area prevalent in the southern end of the route

Recreational potential as an indicator of accessibility control in protected mountain forest areas
Institute of Scientific and Technical Information of China (English)
Tomasz DUDEK
2017-01-01
The article presents research findings related to recreational use of forests located in protected mountainous areas with forestage of over 80％.The study was designed to identify recreational potential of the Carpathian national parks (Bieszczady National Park,Babia Góra National Park,Gorce National Park and Magura National Park;southern Poland) and to compare these findings with the actual number of visitors.The information received on the recreational potential of parks is important from the point of view of protection of natural resources and the financial situation of the parks.The calculated ratio may be an effective tool of management for park administration,that allows to reconcile statutory social and protective functions of national parks.The study determined the recreational potential of the forests with the use of recreational valorisation method designed for areas with varied terrain,and the evaluated factors included the stands of trees with their habitat and land relief.The permissible number of national park visitors,expressed as manhour/ha/year ranges from 19.31 in Bieszczady National Park (BG:19° 35′ E,49° 35′ N) to 32.06 in in Bieszczady National Park (B:22° 40′ E,49° 10′ N).In 3 out of 4 investigated parks,Magnra National Park (M:21°25′ E,49° 30′ N),Gorce National Park (G:20° 10′ E,49° 35′ N),B) recreation carrying capacity was not exceeded,whether or not the strictly protected area is taken into account.Only in BG was the recreation carrying capacity exceeded by nearly 24％,or by 85％ if the strictly protected area is excluded from tourism-related exploitation.The presented procedure for monitoring access to mountain forests in national parks,from the viewpoint of natural resources conservation,can be applied in other mountainous areas covered with forests and exposed to tourist and recreational traffic,and in forests facing particular risk of recreational damage,e.g.in urban and suburban forests growing in areas

the wider network of European corridors.
Until this moment, the logistics and strategic national plans have not been selective concerning the identification, along the TEN-T Corridors, of a few ports and freight villages which are able to become effective European gateways within the Italian territory and attract private investments. Moreover, these planning instruments, instead of basing their strategies on the most concrete corridors have preferred to conceive their policies on entirely “imaginary” ones. This is, for instance, the case of the Logistics Platform in the Nord-East area of Italy. This Platform has been organized around the uncertain Corridor V, rather than the more concrete (but not yet recognized in the European maps Adriatic-Baltic corridor. As a consequence, in this Region, several existing national infrastructures appear, at the moment, largely underused:
- a freight village of considerable size and European standards such as the Interporto Alpe Adria in Cervignano del Friuli, and
- an international double railway such as the “Pontebbana” that links the North-East area of Italy with Austria, through the Alpine pass of Tarvisio, and which is already the southern segment of the Adriatic-Baltic corridor.
On the other hand, these infrastructures might play a significant role in light of the positive estimates about the new trends of maritime trades, which would realize a renewed centrality to the Mediterranean Sea (Drewry Shipping Consultants, 2010, and important development programs regarding the Adriatic ports, involving both public (Venice, Rijeka and private (Monfalcone-Triest, Koper stakeholders. The aim of these projects is to increase the competitive capacity of the North Adriatic port system and establish a more effective connection between it and the central and eastern parts of Europe, through the Baltic-Adriatic Corridor, so as to constitute the so-called North Adriatic Gateway

Data-intensive science gateway for rock physicists and volcanologists.
Filgueira, Rosa; Atkinson, Malcom; Bell, Andrew; Main, Ian; Boon, Steve; Meredith, Philp; Kilburn, Christopher
2014-05-01
Scientists have always shared data and mathematical models of the phenomena they study. Rock physics and Volcanology, as well as other solid-Earth sciences, have increasingly used Internet communications and computational renditions of their models for this purpose over the last two decades. Here we consider how to organise rock physics and volcanology data to open up opportunities for sharing and comparing both experiment data from experiments, observations and model runs and analytic interpretations of these data. Our hypothesis is that if we facilitate productive information sharing across those communities by using a new science gateway, it will benefit the science. The proposed science gateway should make the first steps for making existing research practices easier and facilitate new research. It will achieve this by supporting three major functions: 1) sharing data from laboratories and observatories, experimental facilities and models; 2) sharing models of rock fracture and methods for analysing experimental data; and 3) supporting recurrent operational tasks, such as data collection and model application in real time. We report initial work in two projects (NERC EFFORT and NERC CREEP-2) and experience with an early web-accessible protytpe called EFFORT gateway, where we are implementing such information sharing services for those projects. 1. Sharing data: In EFFORT gateway, we are working on several facilities for sharing data: *Upload data: We have designed and developed a new adaptive data transfer java tool called FAST (Flexible Automated Streaming Transfer) to upload experimental data and metadata periodically from laboratories to our repository. *Visualisation: As data are deposited in the repository, a visualisation of the accumulated data is made available for display in the Web portal. *Metadata and catalogues: The gateway uses a repository to hold all the data and a catalogue to hold all the corresponding metadata. 2. Sharing models and methods

Recreational impacts on Colorado River beaches in Glen Canyon, Arizona
Carothers, Steven W.; Johnson, Robert A.; Dolan, Robert
1984-07-01
Recreational impact was measured on eight beaches in Glen Canyon National Recreation Area and 15 beaches in Grand Canyon National Park using permanently located transects and plots. Recreational impact indices included densities of human trash and charcoal and a measure of sand discoloration due to charcoal. Significant increases in the indices occurred on several Glen Canyon beaches over a seven-month period. Sand discoloration became significantly higher over all Glen Canyon beaches during the same time period. All indices were significantly higher in Glen Canyon than on similar Grand Canyon beaches. These differences are probably due to differences in: (a) level of impacts tolerated by the respective management regimes and, (b) in the number of user days among the two National Park Service administrative units. Management alternatives are presented for reversing the present trends of recreational impact on Glen Canyon beaches.

Recreational drug use has increased considerably among Chinese men who have sex with men (MSM). The phenomenon has the potentially to increase HIV transmission among Chinese MSM. The aims of this study were: 1) to investigate the prevalence of recreational drug use among Chinese MSM, and 2) to explore the correlation between gay smartphone based sex-seeking applications (gay apps), HIV/STIs testing, group sex, commercial sex, sexual roles and poppers use among Chinese MSM. MSM who were born biologically male, were at least 16 years of age and had engaged in anal sex with a man at least once were recruited through a nation-wide online survey in 2014. Information regarding socio-demographics, risk behaviors, recreational drug use, HIV and other STIs testing history and gay app use were collected. Univariate and multivariate analysis were used to determine factors associated with recreational drug use among Chinese MSM. Among 1424 participating MSM, 1100 (77.3%) reported ever using recreational drugs in their lifetime. In the last 12 months, 303 (21.3%) used poppers, 34 (2.4%) used crystal meth and 15 (1.0%) used ecstasy. The mean age of respondents was 25.6±6.8 years, 72.9% identified as gay, 41.3% were students, and 83.8% had never been married. Multiple logistic regression models revealed that compared with non-popper users, popper users were more likely to have been tested for HIV (adjusted OR (aOR) = 1.50, 95% CI: 1.15-1.96) and other STIs (aOR = 1.65, 95% CI: 1.26-2.17). In addition, popper users were more likely to engage in group sex (aOR = 2.63, 95% CI:1.80-3.86), commercial sex (aOR = 1.86, 95% CI:1.13-3.06) and used gay mobile apps to seek sexual partners (aOR = 2.10, 95% CI:1.58-2.80). Chinese MSM has a high rate of recreational drug use, including poppers. Public health programs serving MSM may consider integrating intervention programs to decrease recreational drug use related harms.

Li, Yang
2018-04-01
With the increasing demand for home lifestyle, the traditional smart home products have been unable to meet the needs of users. Aim at the complex wiring, high cost and difficult operation problems of traditional smart home system, this paper designs a home gateway for smart home system based on Wi-Fi and ZigBee. This paper first gives a smart home system architecture base on cloud server, Wi-Fi and ZigBee. This architecture enables users to access the smart home system remotely from Internet through the cloud server or through Wi-Fi at home. It also offers the flexibility and low cost of ZigBee wireless networking for home equipment. This paper analyzes the functional requirements of the home gateway, and designs a modular hardware architecture based on the RT5350 wireless gateway module and the CC2530 ZigBee coordinator module. Also designs the software of the home gateway, including the gateway master program and the ZigBee coordinator program. Finally, the smart home system and home gateway are tested in two kinds of network environments, internal network and external network. The test results show that the designed home gateway can meet the requirements, support remote and local access, support multi-user, support information security technology, and can timely report equipment status information.

Formal Semantics and Implementation of BPMN 2.0 Inclusive Gateways
Christiansen, David Raymond; Carbone, Marco; Hildebrandt, Thomas
We present the first direct formalization of the semantics of inclusive gateways as described in the Business Process Modeling Notation (BPMN) 2.0 Beta 1 specification. The formal semantics is given for a minimal subset of BPMN 2.0 containing just the inclusive and exclusive gateways and the start and stop events. By focusing on this subset we achieve a simple graph model that highlights the particular non-local features of the inclusive gateway semantics. We sketch two ways of implementing the semantics using algorithms based on incrementally updated data structures and also discuss distributed communication-based implementations of the two algorithms.

Deep Space Gateway Science Opportunities
Quincy, C. D.; Charles, J. B.; Hamill, Doris; Sidney, S. C.
2018-01-01
The NASA Life Sciences Research Capabilities Team (LSRCT) has been discussing deep space research needs for the last two years. NASA's programs conducting life sciences studies - the Human Research Program, Space Biology, Astrobiology, and Planetary Protection - see the Deep Space Gateway (DSG) as affording enormous opportunities to investigate biological organisms in a unique environment that cannot be replicated in Earth-based laboratories or on Low Earth Orbit science platforms. These investigations may provide in many cases the definitive answers to risks associated with exploration and living outside Earth's protective magnetic field. Unlike Low Earth Orbit or terrestrial locations, the Gateway location will be subjected to the true deep space spectrum and influence of both galactic cosmic and solar particle radiation and thus presents an opportunity to investigate their long-term exposure effects. The question of how a community of biological organisms change over time within the harsh environment of space flight outside of the magnetic field protection can be investigated. The biological response to the absence of Earth's geomagnetic field can be studied for the first time. Will organisms change in new and unique ways under these new conditions? This may be specifically true on investigations of microbial communities. The Gateway provides a platform for microbiology experiments both inside, to improve understanding of interactions between microbes and human habitats, and outside, to improve understanding of microbe-hardware interactions exposed to the space environment.

In this article, we apply count-data travel-cost methods to a truncated sample of visitors to estimate the Peneda-Gerês National Park (PGNP) average consumer surplus (CS) for each day of visit. The measurement of recreation demand is highly specific because it is calculated by number of days of stay per visit. We therefore propose the application of altered truncated count-data models or truncated count-data models on grouped data to estimate a single, on-site individual recreation demand function, with the price (cost) of each recreation day per trip equal to out-of-pocket and time travel plus out-of-pocket and on-site time costs. We further check the sensitivity of coefficient estimations to alternative models and analyse the welfare measure precision by using the delta and simulation methods by Creel and Loomis. With simulated limits, CS is estimated to be €194 (range €116 to €448). This information is of use in the quest to improve government policy and PNPG management and conservation as well as promote nature-based tourism. To our knowledge, this is the first attempt to measure the average recreation net benefits of each day of stay generated by a national park by using truncated altered and truncated grouped count-data travel-cost models based on observing the individual number of days of stay.

The rock outcrops and cliffs of Shenandoah National Park provide habitat for several rare and endangered plant and animal species, including the federally endangered Shenandoah Salamander (Plethodon shenandoah; Ludwig et al., 1993). The location of the well-known park tour road, Skyline Drive, along the ridgeline provides exceptional access to many outcrops and cliffs throughout the park for a large number of the park?s 1.2 million annual visitors. Consequently, visitor use of cliff areas has led to natural resource impacts, including marked decreases in size and vigor of known rare plant populations. Despite the clear ecological value and potential threats to the natural resources at cliff areas, managers possess little information on visitor use of cliff sites and presently have no formal planning document to guide management. Thus, a park wide study of cliff sites was initiated during the 2005 visitor use season. As part of this research effort, our study used an integrative approach to study recreational use and visitor-caused resource impacts at one of the more heavily visited cliff sites in the park: Little Stony Man Cliffs (LSMC). In particular, this study integrated data from resource impact measurements and visitor use observation to help assess the effects of recreational use on the natural resources of LSMC. Procedures derived from campsite and trail impact studies were used to measure and characterize the amount of visitor-caused resource impacts on LSMC (Marion & Leung, 2001; Marion, 1995). Visitor use observations were conducted on top of LSMC to document and characterize the type and amount of recreational use the cliffs receive and the behaviors of recreationists that may contribute to cliff-top resource impacts. Resource impact measurement data show trampling disturbance present at LSMC, characterized by vegetation loss, exposed soil, and root exposure. Documentation of informal trails, soil erosion, tree damage, and tree stumps provide further

Expansion of the gateway multisite recombination cloning toolkit.
Shearin, Harold K; Dvarishkis, Alisa R; Kozeluh, Craig D; Stowers, R Steven
2013-01-01
Precise manipulation of transgene expression in genetic model organisms has led to advances in understanding fundamental mechanisms of development, physiology, and genetic disease. Transgene construction is, however, a precondition of transgene expression, and often limits the rate of experimental progress. Here we report an expansion of the modular Gateway MultiSite recombination-cloning platform for high efficiency transgene assembly. The expansion includes two additional destination vectors and entry clones for the LexA binary transcription system, among others. These new tools enhance the expression levels possible with Gateway MultiSite generated transgenes and make possible the generation of LexA drivers and reporters with Gateway MultiSite cloning. In vivo data from transgenic Drosophila functionally validating each novel component are presented and include neuronal LexA drivers, LexAop2 red and green fluorescent synaptic vesicle reporters, TDC2 and TRH LexA, GAL4, and QF drivers, and LexAop2, UAS, and QUAS channelrhodopsin2 T159C reporters.

The quagga mussel crisis at Lake Mead National Recreation Area, Nevada (U.S.A.).
Hickey, Valerie
2010-08-01
Parks are cornerstones of conservation; and non-native invasive species drive extensive changes to biological diversity in parks. Knowing this, national park staff at Lake Mead National Recreation Area in the southwestern United States had a program in place for early detection of the non-native, invasive quagga mussel (Dreissena rostriformis bugensis). Upon finding the mussel in January 2007, managers moved quickly to access funding and the best available science to implement a response. Managers considered four options--doing nothing, closing the park, restricting movement on the lakes, and educating and enforcing park visitors--and decided to focus on education and enforcing existing laws. Nonetheless, quagga spread throughout the park and soon began to appear throughout the western United States. I examined why efforts to control the expansion failed and determined the general lessons to be learned from this case. Concentrating human visitation on the lakes through land-use zoning opened a pathway for invasion, reduced management options, and led to the rapid spread of quagga. To reconcile competing mandates to protect nature and provide recreation, zoning in parks has become a common practice worldwide. It reduces stress on some areas of a park by restricting and thus concentrating human activity in particular areas. Concentrating the human activity in one area does three things: cements pathways that repeatedly import and export vectors of non-native invasive species; creates the disturbed area necessary to enable non-native invasive species to gain a foothold; and, establishes a source of invasions that, without appropriate controls, can quickly spread to a park's wilderness areas.

A Smart Gateway Architecture for Improving Efficiency of Home Network Applications
Directory of Open Access Journals (Sweden)
Fei Ding
2016-01-01
Full Text Available A smart home gateway plays an important role in the Internet of Things (IoT system that takes responsibility for the connection between the network layer and the ubiquitous sensor network (USN layer. Even though the home network application is developing rapidly, researches on the home gateway based open development architecture are less. This makes it difficult to extend the home network to support new applications, share service, and interoperate with other home network systems. An integrated access gateway (IAGW is proposed in this paper which upward connects with the operator machine-to-machine platform (M2M P/F. In this home network scheme, the gateway provides standard interfaces for supporting various applications in home environments, ranging from on-site configuration to node and service access. In addition, communication management ability is also provided by M2M P/F. A testbed of a simple home network application system that includes the IAGW prototype is created to test its user interaction capabilities. Experimental results show that the proposed gateway provides significant flexibility for users to configure and deploy a home automation network; it can be applied to other monitoring areas and simultaneously supports a multi-ubiquitous sensor network.

XDS-I Gateway Development for HIE Connectivity with Legacy PACS at Gil Hospital.
Simalango, Mikael Fernandus; Kim, Youngchul; Seo, Young Tae; Choi, Young Hwan; Cho, Yong Kyun
2013-12-01
The ability to support healthcare document sharing is imperative in a health information exchange (HIE). Sharing imaging documents or images, however, can be challenging, especially when they are stored in a picture archiving and communication system (PACS) archive that does not support document sharing via standard HIE protocols. This research proposes a standard-compliant imaging gateway that enables connectivity between a legacy PACS and the entire HIE. Investigation of the PACS solutions used at Gil Hospital was conducted. An imaging gateway application was then developed using a Java technology stack. Imaging document sharing capability enabled by the gateway was tested by integrating it into Gil Hospital's order communication system and its HIE infrastructure. The gateway can acquire radiology images from a PACS storage system, provide and register the images to Gil Hospital's HIE for document sharing purposes, and make the images retrievable by a cross-enterprise document sharing document viewer. Development of an imaging gateway that mediates communication between a PACS and an HIE can be considered a viable option when the PACS does not support the standard protocol for cross-enterprise document sharing for imaging. Furthermore, the availability of common HIE standards expedites the development and integration of the imaging gateway with an HIE.

Marijuana or Cannabis is extensively used as a recreational substance globally. Case reports have reported cardiac arrhythmias immediately following recreational marijuana use. However, the burden of arrhythmias in hospitalized marijuana users have not been evaluated through prospective or cross-sectional studies. Therefore, we planned to measure temporal trends of the frequency of arrhythmias in hospitalized marijuana users using National Inpatient Sample (NIS) database in the United States.

The Gateway Reflex, a Novel Neuro-Immune Interaction for the Regulation of Regional Vessels
Directory of Open Access Journals (Sweden)
Yuki Tanaka
2017-10-01
Full Text Available The gateway reflex is a new phenomenon that explains how immune cells bypass the blood–brain barrier to infiltrate the central nervous system (CNS and trigger neuroinflammation. To date, four examples of gateway reflexes have been discovered, each described by the stimulus that evokes the reflex. Gravity, electricity, pain, and stress have all been found to create gateways at specific regions of the CNS. The gateway reflex, the most recently discovered of the four, has also been shown to upset the homeostasis of organs in the periphery through its action on the CNS. These reflexes provide novel therapeutic targets for the control of local neuroinflammation and organ function. Each gateway reflex is activated by different neural activations and induces inflmammation at different regions in the CNS. Therefore, it is theoretically possible to manipulate each independently, providing a novel therapeutic strategy to control local neuroinflammation and peripheral organ homeostasis.

Kai Guan
2017-01-01
Full Text Available This paper proposed a remote health monitoring system for the elderly based on smart home gateway. The proposed system consists of three parts: the smart clothing, the smart home gateway, and the health care server. The smart clothing collects the elderly’s electrocardiogram (ECG and motion signals. The home gateway is used for data transmission. The health care server provides services of data storage and user information management; it is constructed on the Windows-Apache-MySQL-PHP (WAMP platform and is tested on the Ali Cloud platform. To resolve the issues of data overload and network congestion of the home gateway, an ECG compression algorithm is applied. System demonstration shows that the ECG signals and motion signals of the elderly can be monitored. Evaluation of the compression algorithm shows that it has a high compression ratio and low distortion and consumes little time, which is suitable for home gateways. The proposed system has good scalability, and it is simple to operate. It has the potential to provide long-term and continuous home health monitoring services for the elderly.

The benefits of improving recreation quality and quantity
Energy Technology Data Exchange (ETDEWEB)
Krupnick, A; Holmes, R
1994-07-01
Of all valuation areas in environmental economics, studies addressing the nonmarketed services of recreation (mostly fishing and mostly salt water-based) are by far the most prevalent, owing to the early insight on valuation methods offered by the Clawson travel cost model; the theoretical complexities, and thus the academic attractiveness of estimating benefits in this area; many government funders; and widely available data. To give some idea of the magnitude of work in this area, Smith and Kaoru (1990) performed a meta-analysis on 77 studies of recreation demand, and Walsh, Johnson, and McKean 1988) reviewed 120 studies of the value of various types of recreation-activity days. Most of these studies pertain to individual sites or clusters of sites in a region. Some seek estimates of national recreation benefits.

Wild Carpathia Future Development: From Illegal Deforestation to ORV Sustainable Recreation
Directory of Open Access Journals (Sweden)
Mihai Voda
2017-12-01
Full Text Available Romanian Wild Carpathia constitutes the ultimate pristine wilderness of the old European continent. Carpathian Mountains landscape experiences and outdoor recreation represents quite unique cultural ecosystem services. The new annotations to the Forest Law are restricting any public access in the woods without authorities’ pre-approval for organised sport, leisure and tourism activities. However, off road vehicle (ORV recreation is a popular activity and a growing transparency concern of National Forest Administration Authorities that is not managed accordingly. Here we show that our ORV recreation frame model can securely allow public access and protect all Romanian mountains. Our results demonstrate how growing ORV recreation popularity can be used in an honest and open way if it is well organized and controlled. We anticipate our assay to be a starting point for a regional and national forest administration sustainable development plan. Furthermore, stopping illegal forest activities is a major target of the anti-logging movement. A well-defined assay for the ORV recreation frame model will be relevant for such developments.

Benefits and risks of adopting the global code of practice for recreational fisheries
Arlinghaus, Robert; Beard, T. Douglas; Cooke, Steven J.; Cowx, Ian G.
2012-01-01
Recreational fishing constitutes the dominant or sole use of many fish stocks, particularly in freshwater ecosystems in Western industrialized countries. However, despite their social and economic importance, recreational fisheries are generally guided by local or regional norms and standards, with few comprehensive policy and development frameworks existing across jurisdictions. We argue that adoption of a recently developed Global Code of Practice (CoP) for Recreational Fisheries can provide benefits for moving recreational fisheries toward sustainability on a global scale. The CoP is a voluntary document, specifically framed toward recreational fisheries practices and issues, thereby complementing and extending the United Nation's Code of Conduct for Responsible Fisheries by the Food and Agricultural Organization. The CoP for Recreational Fisheries describes the minimum standards of environmentally friendly, ethically appropriate, and—depending on local situations—socially acceptable recreational fishing and its management. Although many, if not all, of the provisions presented in the CoP are already addressed through national fisheries legislation and state-based fisheries management regulations in North America, adopting a common framework for best practices in recreational fisheries across multiple jurisdictions would further promote their long-term viability in the face of interjurisdictional angler movements and some expanding threats to the activity related to shifting sociopolitical norms.

The U.S. Geological Survey, in cooperation with the National Park Service conducted an intensive assessment of selected springs along the Colorado River Corridor in Arches National Park, Canyonlands National Park, Glen Canyon National Recreation Area, and Grand Canyon National Park in 1997 and 1998, for the purpose of measuring and evaluating the water quality and quantity of the resource. This study was conducted to establish baseline data for the future evaluation of possible effects from recreational use and climate change. Selected springs and seeps were visited over a study period from 1997 to 1998, during which, discharge and on-site chemical measurements were made at selected springs and seeps, and samples were collected for subsequent chemical laboratory analysis. This interdisciplinary study also includes simultaneous studies of flora and fauna, measured and sampled coincidently at the same sites. Samples collected during this study were transported to U.S. Geological Survey laboratories in Boulder, Colorado, where analyses were performed using state-of-the-art laboratory technology. The location of the selected springs and seeps, elevation, geology, aspect, and onsite measurements including temperature, discharge, dissolved oxygen, pH, and specific conductance, were recorded. Laboratory analyses include determinations for alkalinity, aluminum, ammonium (nitrogen), antimony, arsenic, barium, beryllium, bismuth, boron, bromide, cadmium, calcium, cerium, cesium, chloride, chromium, cobalt, copper, dissolved inorganic carbon, dissolved organic carbon, dysprosium, erbium, europium, fluoride, gadolinium, holmium, iodine, iron, lanthanum, lead, lithium, lutetium, magnesium, manganese, mercury, molybdenum, neodymium, nickel, nitrate (nitrogen), nitrite (nitrogen), phosphate, phosphorus, potassium, praseodymium, rhenium, rubidium, samarium, selenium, silica, silver, sodium, strontium, sulfate, tellurium, terbium, thallium, thorium, thulium, tin, titanium, tungsten

Lightning injuries in sports and recreation.
Thomson, Eric M; Howard, Thomas M
2013-01-01
The powers of lightning have been worshiped and feared by all known human cultures. While the chance of being struck by lightning is statistically very low, that risk becomes much greater in those who frequently work or play outdoors. Over the past 2 yr, there have been nearly 50 lightning-related deaths reported within the United States, with a majority of them associated with outdoor recreational activities. Recent publications primarily have been case studies, review articles, and a discussion of a sixth method of injury. The challenge in reducing lightning-related injuries in organized sports has been addressed well by both the National Athletic Trainers' Association and the National Collegiate Athletic Association in their guidelines on lightning safety. Challenges remain in educating the general population involved in recreational outdoor activities that do not fall under the guidelines of organized sports.

Recreational system optimization to reduce conflict on public lands.
Shilling, Fraser; Boggs, Jennifer; Reed, Sarah
2012-09-01
In response to federal administrative rule, the Tahoe National Forest (TNF), California, USA engaged in trail-route prioritization for motorized recreation (e.g., off-highway-vehicles) and other recreation types. The prioritization was intended to identify routes that were suitable and ill-suited for maintenance in a transportation system. A recreational user survey was conducted online (n = 813) for user preferences for trail system characteristics, recreational use patterns, and demographics. Motorized trail users and non-motorized users displayed very clear and contrasting preferences for the same system. As has been found by previous investigators, non-motorized users expressed antagonism to motorized use on the same recreational travel system, whereas motorized users either supported multiple-use routes or dismissed non-motorized recreationists' concerns. To help the TNF plan for reduced conflict, a geographic information system (GIS) based modeling approach was used to identify recreational opportunities and potential environmental impacts of all travel routes. This GIS-based approach was based on an expert-derived rule set. The rules addressed particular environmental and recreation concerns in the TNF. Route segments were identified that could be incorporated into minimal-impact networks to support various types of recreation. The combination of potential impacts and user-benefits supported an optimization approach for an appropriate recreational travel network to minimize environmental impacts and user-conflicts in a multi-purpose system.

2005-03-01
Although mobile users are currently offered a lot more capabilities on their mobile devices, they still experience some limitations. They can surf the Internet, read their e-mail and receive MMS messages, but they have limited processing power, storage capacity and bandwidth and are limited in their access to peripherals (e.g. printers). We have designed and implemented a multimedia gateway for mobile devices that reduces these limitations. It gives the mobile devices transparent access to high capacity devices connected to the gateway, which is built around a central, modularly extensible server that can run on any PC or home gateway. It manages two sets of modules: one set offering the actual services and another set handling the IP-based wireless interaction with the client applications on the mobile devices. These modules can be added and removed dynamically, offering new services on the fly. Currently services for storage, printing, domotics and playing music are provided. Others can easily be added later on. This paper discusses the architecture and development, the management of modules, the actual services and their benefits. Besides a proprietary implementation, it also looks into OSGi and how both platforms compare to each other, concerning design, architecture, ease of development, functionality, ...

Marine gateways prove to be important factors for changes in the ecology and biochemistry of marginal seas. Changes in gateway configuration played a dominant role in the Middle Miocene paleogeographic evolution of the Paratethys Sea that covered Central Eurasia. Here, we focus on the connection between the Central (CP) and Eastern Paratethys (EP) to understand the paleoenvironmental changes caused by the evolution of this marine gateway. We first construct an integrated magneto-biostratigraphic framework for the late Langhian-Serravallian (Chokrakian-Karaganian-Konkian-Volhynian) sedimentary record of the eastern domain, which allows a correlation to the well-dated successions west of the gateway. The magneto-biostratigraphic results from the Zelensky-Panagia section on the Black Sea coast of Russia show that the Chokrakian/Karaganian boundary has an age of 13.8 Ma, the Karaganian/Konkian boundary is dated at 13.4 Ma, and the Konkian/Volhynian boundary at 12.65 Ma. We identify three major phases on gateway functioning that are reflected in specific environmental changes. During the Karaganian, the EP turned into a lake-sea that supplied a unidirectional flow of low-salinity waters to the west, where the CP sea experienced its Badenian Salinity Crisis. This configuration is remarkably similar to the Mediterranean during its Messinian Salinity Crisis. The second phase is marked by a marine transgression from the west, reinstalling open-marine conditions in the CP and causing marine incursions in the EP during the Konkian. The Volhynian is characterized by a new gateway configuration that allows exchange between CP and EP, creating unified conditions all over the Paratethys. We hypothesize that a density driven pumping mechanism is triggered by the increase in connectivity at the Konkian/Volhynian boundary, which simultaneously caused major paleoenvironmental changes at both sides of the gateway and led to the Badenian-Sarmatian extinction event in the CP.

Full Text Available To evaluate the consistency of the relationship between early drug use in adolescence and illegal drug use in adulthood as proposed in the “gateway theory” and to determine whether pre-existing depressive symptoms modifies this relationship. We used contractual data from the National Longitudinal Study of Adolescent to Adult health data spanning a 14 year period. We assessed the relationship between gateway drugs at baseline (age 11–20 years and drug use in adulthood using generalized estimating equation (GEE regression models. Gateways drugs used in early adolescence were significantly associated with marijuana use, illegal drugs and cocaine in older adolescence, but over time these relationships were not consistent in adulthood. Changes in the pattern of psychoactive drug use were important predictors of drug use in adulthood. A history of higher depressive symptoms was associated with higher frequencies of psychoactive drug use over time. Users of mental health services in adolescence were less likely to use drugs in older adolescence and in adulthood. Relationships between early drug use and later drug use in adulthood cannot be solely explained by the gateway hypothesis. Collectively, adolescent drug prevention and treatment programs should apply theory-based and evidence-proven multisectoral intervention strategies rather than providing a brief counseling on individual's behaviors. This evidence should include understanding that changes in behavior should involve broader analyses of the underlying social context for drug use and in particular the role of the community social norms in driving a group's behaviors.

Participation by US adults in sports, exercise, and recreational physical activities.
Ham, Sandra A; Kruger, Judy; Tudor-Locke, Catrine
2009-01-01
Given the evidence that regular physical activity produces substantial health benefits, participation in sports, exercise, and recreation is widely encouraged. The objective of this study was to describe participation in sports, exercise, and recreational physical activities among US adults. Data from 2 national surveys of respondents age 18 years and older were analyzed. Respondents to the American Time Use Survey (ATUS) from 2003 through 2005 (N=45,246) reported all activities on 1 randomly selected survey day. Respondents to the National Health and Nutrition Examination Survey (NHANES) from 1999 through 2004 (N=17,061) reported leisure-time physical activities in the 30 days before the interview. One-quarter of adults participated in any sport, exercise, or recreational activity on a random day, and 60.9% of adults participated in any leisure-time activity in the previous 30 days. The most common types of activities were walking, gardening and yard work, and other forms of exercise. The sports and recreational activities had typical durations of 1/2 to 3 hours per session, and the exercise activities typically lasted 1 hour or less. The prevalence of sports, exercise, and recreational physical activities is generally low among US adults; exercise is the most commonly reported type of activity.

2010-12-01
Full Text Available Recent studies show inter-related trends in both adult and youth populations in developed nations: a shift away from nature-based recreation, an overall decline in physical activity, and increasing obesity. For this study we examined gender patterns in a nature-based activity, observing wild birds, popular in two developed nations, the USA and UK. We collated data from several organizations and categorized data sources as representing activities that involve varying degrees of competitiveness and acting authoritatively. Patterns were consistent with the hypotheses that gender differences in preferred types of bird-related recreation reflected well documented gender-specific differences in preferences for competition and propensity to act authoritatively. Observing birds encompassed both a recreational hobby, "bird watching," that was female biased in the USA, and a competitive sport, "birding," that was heavily male biased among adults, but not youth, in both the USA and UK. Because of differences in gender participation in bird-related activities, fostering both competitive and noncompetitive bird-related activities is necessary to increase the likelihood of bringing larger segments of the population into nature-based recreation.

Given a social network, who is the best person to introduce you to, say, Chris Ferguson, the poker champion? Or, given a network of people and skills, who is the best person to help you learn about, say, wavelets? The goal is to find a small group of 'gateways': persons who are close enough to us, as well as close enough to the target (person, or skill) or, in other words, are crucial in connecting us to the target. The main contributions are the following: (a) we show how to formulate this problem precisely; (b) we show that it is sub-modular and thus it can be solved near-optimally; (c) we give fast, scalable algorithms to find such gateways. Experiments on real data sets validate the effectiveness and efficiency of the proposed methods, achieving up to 6,000,000x speedup.

The use of recreational drugs of abuse continues to expand without limitations to national boundaries, social status, race, or education. Beyond the prevalence of illicit drug use and dependence, their contribution to the global burden of disease and death are large and troubling. All medical providers should be aware of the evolving drugs of abuse and their medical and social consequences. In addition to heroin and stimulants such as cocaine and methamphetamine, new designer stimulants called "bath salts" and cannabinoids called "spice," along with the abuse of prescription drugs and volatile substances, are now widely recognized problems in many societies. The wide variety and continuingly expanding clinical manifestations of toxicity of recreational drugs of abuse is not widely appreciated by clinicians. This edition attempts to summarize six major classes of drugs of abuse and their clinical effects with special emphasis on their immunological and respiratory effects.

Full Text Available Horton Plains National Park (HPNP is an area of high biodiversity and exceptional endemism receiving high visitation (166,613 visitors in 2009, both by local and foreigners. Although, tourism causes negative impacts on the environment, environmental valuation could be used for taking decisions on natural resources management. The study shows that the recreational value of HPNP is Rs. 51.68 million rupees per year, but the total economic value could be many times higher than this. Calculations showed the maximum revenue from the park could be obtained if the entrance fee is raised to Rs. 472.00. This may however reduce the present visitor number by 65%, but it will improve the total revenue of the park by 314 %. These differences strengthen the common argument by both officials and the public regarding insufficient allocation of man power and funds for natural resources management.Key words: wildlife, recreational value, travel cost method

The warmest global temperatures of the past 85 million years occurred during a prolonged greenhouse episode known as the Early Eocene Climatic Optimum (52-50 Ma). The Early Eocene Climatic Optimum terminated with a long-term cooling trend that culminated in continental-scale glaciation of Antarctica from 34 Ma onward. Whereas early studies attributed the Eocene transition from greenhouse to icehouse climates to the tectonic opening of Southern Ocean gateways, more recent investigations invoked a dominant role of declining atmospheric greenhouse gas concentrations (e.g., CO2). However, the scarcity of field data has prevented empirical evaluation of these hypotheses. We present marine microfossil and organic geochemical records spanning the early-to-middle Eocene transition from the Wilkes Land Margin, East Antarctica. Dinoflagellate biogeography and sea surface temperature paleothermometry reveal that the earliest throughflow of a westbound Antarctic Counter Current began ~49-50 Ma through a southern opening of the Tasmanian Gateway. This early opening occurs in conjunction with the simultaneous onset of regional surface water and continental cooling (2-4 °C), evidenced by biomarker- and pollen-based paleothermometry. We interpret that the westbound flowing current flow across the Tasmanian Gateway resulted in cooling of Antarctic surface waters and coasts, which was conveyed to global intermediate waters through invigorated deep convection in southern high latitudes. Although atmospheric CO2 forcing alone would provide a more uniform middle Eocene cooling, the opening of the Tasmanian Gateway better explains Southern Ocean surface water and global deep ocean cooling in the apparent absence of (sub-) equatorial cooling.

A Standard-Based and Context-Aware Architecture for Personal Healthcare Smart Gateways.
Santos, Danilo F S; Gorgônio, Kyller C; Perkusich, Angelo; Almeida, Hyggo O
2016-10-01
The rising availability of Personal Health Devices (PHDs) capable of Personal Network Area (PAN) communication and the desire of keeping a high quality of life are the ingredients of the Connected Health vision. In parallel, a growing number of personal and portable devices, like smartphones and tablet computers, are becoming capable of taking the role of health gateway, that is, a data collector for the sensor PHDs. However, as the number of PHDs increase, the number of other peripherals connected in PAN also increases. Therefore, PHDs are now competing for medium access with other devices, decreasing the Quality of Service (QoS) of health applications in the PAN. In this article we present a reference architecture to prioritize PHD connections based on their state and requirements, creating a healthcare Smart Gateway. Healthcare context information is extracted by observing the traffic through the gateway. A standard-based approach was used to identify health traffic based on ISO/IEEE 11073 family of standards. A reference implementation was developed showing the relevance of the problem and how the proposed architecture can assist in the prioritization. The reference Smart Gateway solution was integrated with a Connected Health System for the Internet of Things, validating its use in a real case scenario.

Toward a U.S. National Phenological Assessment
Henebry, Geoffrey M.; Betancourt, Julio L.
2010-01-01
Third USA National Phenology Network (USA-NPN) and Research Coordination Network (RCN) Annual Meeting; Milwaukee, Wisconsin, 5-9 October 2009; Directional climate change will have profound and lasting effects throughout society that are best understood through fundamental physical and biological processes. One such process is phenology: how the timing of recurring biological events is affected by biotic and abiotic forces. Phenology is an early and integrative indicator of climate change readily understood by nonspecialists. Phenology affects the planting, maturation, and harvesting of food and fiber; pollination; timing and magnitude of allergies and disease; recreation and tourism; water quantity and quality; and ecosystem function and resilience. Thus, phenology is the gateway to climatic effects on both managed and unmanaged ecosystems. Adaptation to climatic variability and change will require integration of phenological data and models with climatic forecasts at seasonal to decadal time scales. Changes in phenologies have already manifested myriad effects of directional climate change. As these changes continue, it is critical to establish a comprehensive suite of benchmarks that can be tracked and mapped at local to continental scales with observations and climate models.

Data from the Gambling Impact and Behavior Study (GIBS), a national survey of 2417 U.S. adults, were examined by multivariate analysis to investigate characteristics of past-year recreational gamblers who participated in casino-only, non-casino-only, and both casino and non-casino gambling. Compared to non-casino-only gamblers, individuals who gambled in both locations had higher rates of alcohol use and abuse/dependence, lower rates of drug use, more frequent gambling, and larger wins and losses. Compared to casino-only gamblers, individuals who gambled in both locations reported less drug use, poorer subjective health, earlier age of gambling onset, greater frequency of gambling, and larger wins and losses. Compared to casino-only or non-casino-only gambling, gambling in both locations was associated with more frequent and heavier gambling. Findings suggest aspects of recreational gambling, such as gambling venue, may have important public health implications and should be considered in guidelines for responsible gambling.

Full Text Available Sustainable tourism management plans rely on relevant and consistent information about factors that can influence the decision to visit a protected area. This paper uses the choice experiment method to investigate tourists’ preferences with regard to recreational trip characteristics in national and natural parks in Romania. An on-site survey questionnaire was administered to visitors. The multinomial logit model was employed to investigate the preference orderings of the identified groups of recreational users. Overall, results indicate that tourists gain benefits after visiting the parks. Main preference differences were found for information sources and location of campsites. Visitors who stated that the park was the main trip destination were willing to have access to more information sources, the marks on trails being insufficient. Camping is preferred only in organized places, expressing the concern for environmental protection. The results of this study have management implications, highlighting the importance of assessing tourists’ preferences as a foundation for developing sustainable tourism strategies.

The ATLAS Gateway service is implemented with a set of dedicated computer nodes to provide a fine-grained access control between CERN General Public Network (GPN) and ATLAS Technical Control Network (ATCN). ATCN connects the ATLAS online farm used for ATLAS Operations and data taking, including the ATLAS TDAQ (Trigger and Data Aquisition) and DCS (Detector Control System) nodes. In particular, it provides restricted access to the web services (proxy), general login sessions (via SSH and RDP protocols), NAT and mail relay from ATCN. At the Operating System level the implementation is based on virtualization technologies. Here we report on the Gateway upgrade during Long Shutdown 1 (LS1) period: it includes the transition to the last production release of the CERN Linux distribution (SLC6), the migration to the centralized configuration management system (based on Puppet) and the redesign of the internal system architecture.

Available data suggest that medical marijuana users may have more mental health problems than recreational marijuana users. There is limited information about differences in behavioral health disorders and unmet treatment needs between medical and recreational marijuana users. We compared past-year prevalence of behavioral health disorders and unmet treatment needs across three marijuana subgroups (recreational use only, medical use only, and both). Sex-stratified logistic regression was performed to determine their associations with marijuana use status. We analyzed data from adults (≥18 years) who used marijuana in the past year (N=15,440) from 2013 to 2014 National Surveys on Drug Use and Health. Among 15,440 past-year marijuana users, 90.2% used recreational marijuana only, 6.2% used medical marijuana only, and 3.6% used both. Both users had the highest prevalence of behavioral health disorders and unmet treatment needs overall, with no significant sex differences. In the sex-specific logistic regression analysis, medical only users and both users showed somewhat different patterns of associations (reference group=recreational only users). Medical only users had decreased odds of alcohol or drug use disorders, and unmet need for alcohol or drug treatment among males and females. Additionally, female medical only users had decreased odds of opioid use disorder. Both users had increased odds of major depressive episode, hallucinogen use disorder, and unmet need for mental health services among males, and cocaine use disorder among females. Different approaches tailored to individuals' sex and motives for marijuana use is needed for the prevention and treatment of behavioral health problems. Copyright © 2017 Elsevier B.V.

Full Text Available The research objective is the rationale of the theoretical and methodical approach concerning the improvement of regulatory policy as well as the process of distribution of financial investments using the model of the functioning of a recreational sector of the national economy. The methodology of the study includes the use of optimal control theory for the model formation of the functioning of the recreational industry as well as determining the behaviour of regulatory authorities and capabilities to optimize the allocation of investment resources in the recreational sector of the national economy. Results. The issue of equilibration of regulatory policy in the recreational sector of the national economy is actualized, including the question of targeted distribution of state and external financial investments. Also, it is proved that regulatory policy should establish the frameworks that on the one hand, do not allow public authorities to exercise extra influence on the economy of recreation, on the other hand, to keep the behaviour of the recreational business entities within the limits of normal socio-economic activity – on the basis of analysis of the continuum “recreation – work” by means of modified Brennan-Buchanan model. It is revealed that even with the condition of the tax reduction, the situation when the population resting less and works more than in the background of a developed economy is observed. However, according to the optimistic forecast, eventually on condition when the economy is emerging from the shade, we will obtain an official mode of the work in which, while maintaining taxes on proposed more advantageous for the population level, ultimately the ratio leisure and work will be established which is corresponding to the principles of sustainable development.

STEM Education as a Gateway to Future Astronomy: the Case of Ethiopian Universities
Adhana Teklr, Kelali
2015-08-01
Over last two decades education sector in Ethiopia has got due attention. To meet the education deficit of the nation number of universities has been increased from two to thirty eight and twelve more are coming soon. The proliferation has brought a spillover effect that universities have to compete for center excellence in research and education. Convincingly, government’s support is geared towards knowledge-based and innovation-driven system of education to back up the green economic development plan.In an effort to build inclusive economic development emphasis is given to innovative competency building through science and technology fields. The universities in the nation have establish laboratories to educate school boys and girls at early stage of their schooling in STEM (Science, Technology, Engineering and Mathematics) subjects as means to paving future destiny. Though most of the astronomy and space science labs are virtual ones; more and more student have been inspired and want astronomy and space science as their future career fields. Assessment study carried out in universities running STEM education showed that there is a mismatch between the capacity of the labs and number of students wanted to study astronomy and space sciences. The universities have endorsed that STEM education is the gateway to future astronomy and strongly advised concerned bodies and partnering institutions to collaboratively work to intensify the teaching-learning of STEM subjects.The assessment study compiled astronomic and space science exercises carried out by instructors and students and the document is ready to be disseminated to universities and middle and secondary schools to promote the science nationwide. The results have motivated university instructors, science and technology professionals, researchers and policy makers to be more involved in shaping future destiny of the young generation and have their shown determination to support the STEM education so that it will

SET: Session Layer-Assisted Efficient TCP Management Architecture for 6LoWPAN with Multiple Gateways
Directory of Open Access Journals (Sweden)
Akbar AliHammad
2010-01-01
Full Text Available 6LoWPAN (IPv6 based Low-Power Personal Area Network is a protocol specification that facilitates communication of IPv6 packets on top of IEEE 802.15.4 so that Internet and wireless sensor networks can be inter-connected. This interconnection is especially required in commercial and enterprise applications of sensor networks where reliable and timely data transfers such as multiple code updates are needed from Internet nodes to sensor nodes. For this type of inbound traffic which is mostly bulk, TCP as transport layer protocol is essential, resulting in end-to-end TCP session through a default gateway. In this scenario, a single gateway tends to become the bottleneck because of non-uniform connectivity to all the sensor nodes besides being vulnerable to buffer overflow. We propose SET; a management architecture for multiple split-TCP sessions across a number of serving gateways. SET implements striping and multiple TCP session management through a shim at session layer. Through analytical modeling and ns2 simulations, we show that our proposed architecture optimizes communication for ingress bulk data transfer while providing associated load balancing services. We conclude that multiple split-TCP sessions managed in parallel across a number of gateways result in reduced latency for bulk data transfer and provide robustness against gateway failures.

Flooding and subsidence in the Thames Gateway: impact on insurance loss potential
Royse, Katherine; Horn, Diane; Eldridge, Jillian; Barker, Karen
2010-05-01
and sediment, or rehydration of sediment under flood water. The latter mechanism may be particularly critical on sites where Holocene sediments are currently protected from flooding and are no longer subsiding. Holocene deposits tend to compress, either under their own weight or under a superimposed load such as made ground, built structures or flood water. If protected dry sediments become flooded in the future, subsidence would be expected to resume. This research project aims to investigate the correlation between flood hazards and subsidence hazards and the effect that these two sources of risk will have on insurance losses in the Thames Gateway. In particular, the research will explore the potential hydrological and geophysical drivers and links between flood and subsidence events within the Thames Gateway, assessing the potential for significant event occurrence within the timescales relevant to insurers. In the first part of the project we have identified flood risk areas within the Thames Gateway development zone which have a high risk of flooding and may be affected by renewed or increased subsidence. This has been achieved through the use of national and local-scale 2D and 3D geo-environmental information such as the Geosure dataset (e.g. swell-shrink, collapsible and compressible deposits data layers), PSI data, thickness of superficial and artificial land deposits, and flood potential data etc. In the second stage of the project we will investigate the hydrological and geophysical links between flooding and subsidence events on developed sites; quantify the insurance loss potential in the Thames Gateway from correlated flooding and subsidence events; consider how climate change will affect risk to developments in the Thames Gateway in the context of subsidence and flooding; and develop new ways of communicating and visualise correlated flood and subsidence risk to a range of stakeholders, including the insurance industry, planners, policy makers and the

All gates lead to smoking: the 'gateway theory', e-cigarettes and the remaking of nicotine.
Bell, Kirsten; Keane, Helen
2014-10-01
The idea that drug use in 'softer' forms leads to 'harder' drug use lies at the heart of the gateway theory, one of the most influential models of drug use of the twentieth century. Although hotly contested, the notion of the 'gateway drug' continues to rear its head in discussions of drug use--most recently in the context of electronic cigarettes. Based on a critical reading of a range of texts, including scholarly literature and media reports, we explore the history and gestation of the gateway theory, highlighting the ways in which intersections between academic, media and popular accounts actively produced the concept. Arguing that the theory has been critical in maintaining the distinction between 'soft' and 'hard' drugs, we turn to its distinctive iteration in the context of debates about e-cigarettes. We show that the notion of the 'gateway' has been transformed from a descriptive to a predictive model, one in which nicotine is constituted as simultaneously 'soft' and 'hard'--as both relatively innocuous and incontrovertibly harmful.

It is presumed that recreation activities have a variety of functions for people, from tension reduction to citizenship development; however, a recreation activity's most empirically obvious function is as a reinforcer. This study demonstrates how two recurrent problems of urban recreation programs—recruitment of members and reduction of disruptive behaviors within the program—can be handled simply by contingently adjusting the amount of time the recreation activities are available. When extra time in the recreation center was provided to those youths who brought new members, dramatic increases in membership were achieved. On the other hand, when the closing time for each evening's recreation program was publicly moved forward by a few minutes for each offense, disruptive behaviors were nearly eliminated. Recreation used as a reinforcer can thus improve the basic operation of a recreation center and might similarly enhance other presumed and desired functions of recreation. PMID:16795471

Competitive Swarm Optimizer Based Gateway Deployment Algorithm in Cyber-Physical Systems.
Huang, Shuqiang; Tao, Ming
2017-01-22
Wireless sensor network topology optimization is a highly important issue, and topology control through node selection can improve the efficiency of data forwarding, while saving energy and prolonging lifetime of the network. To address the problem of connecting a wireless sensor network to the Internet in cyber-physical systems, here we propose a geometric gateway deployment based on a competitive swarm optimizer algorithm. The particle swarm optimization (PSO) algorithm has a continuous search feature in the solution space, which makes it suitable for finding the geometric center of gateway deployment; however, its search mechanism is limited to the individual optimum (pbest) and the population optimum (gbest); thus, it easily falls into local optima. In order to improve the particle search mechanism and enhance the search efficiency of the algorithm, we introduce a new competitive swarm optimizer (CSO) algorithm. The CSO search algorithm is based on an inter-particle competition mechanism and can effectively avoid trapping of the population falling into a local optimum. With the improvement of an adaptive opposition-based search and its ability to dynamically parameter adjustments, this algorithm can maintain the diversity of the entire swarm to solve geometric K -center gateway deployment problems. The simulation results show that this CSO algorithm has a good global explorative ability as well as convergence speed and can improve the network quality of service (QoS) level of cyber-physical systems by obtaining a minimum network coverage radius. We also find that the CSO algorithm is more stable, robust and effective in solving the problem of geometric gateway deployment as compared to the PSO or Kmedoids algorithms.

To assess agreement among three nutrient profiling systems used to evaluate the healthfulness of vending machine products in recreation and sport settings in three Canadian provinces. We also assessed whether the nutritional profile of vending machine items in recreation and sport facilities that were adhering to nutrition guidelines (implementers) was superior to that of facilities that were not (non-implementers). Trained research assistants audited the contents of vending machines. Three provincial nutrient profiling systems were used to classify items into each province's most, moderately and least healthy categories. Agreement among systems was assessed using weighted κ statistics. ANOVA assessed whether the average nutritional profile of vending machine items differed according to province and guideline implementation status. Eighteen recreation and sport facilities in three Canadian provinces. One-half of facilities were implementing nutrition guidelines. Snacks (n 531) and beverages (n 618) within thirty-six vending machines were audited. Overall, the systems agreed that the majority of items belonged within their respective least healthy categories (66-69 %) and that few belonged within their most healthy categories (14-22 %). Agreement among profiling systems was moderate to good, with κ w values ranging from 0·49 to 0·69. Implementers offered fewer of the least healthy items (P<0·05) and these items had a better nutritional profile compared with items in non-implementing facilities. The policy outcomes of the three systems are likely to be similar, suggesting there may be scope to harmonize nutrient profiling systems at a national level to avoid unnecessary duplication and support food reformulation by industry.

Research codes are effective for illustrating complex concepts in educational fluid dynamics courses, compared to textbook examples, an interactive three-dimensional visualisation can bring a problem to life! Various barriers, however, prevent the adoption of research codes in teaching: codes are typically created for highly-specific `once-off' calculations and, as such, have no user interface and a steep learning curve. Moreover, a code may require access to high-performance computing resources that are not readily available in the classroom. This project allows academics to rapidly work research codes into their teaching via a minimalist `science gateway' framework. The gateway is a simple, yet flexible, web interface allowing students to construct and run simulations, as well as view and share their output. Behind the scenes, the common operations of job configuration, submission, monitoring and post-processing are customisable at the level of shell scripting. In this talk, we demonstrate the creation of an example teaching gateway connected to the Code BLUE fluid dynamics software. Student simulations can be run via a third-party cloud computing provider or a local high-performance cluster. EPSRC, UK, MEMPHIS program Grant (EP/K003976/1), RAEng Research Chair (OKM).

Efficient and robust subcloning is essential for the construction of high-diversity DNA libraries in the field of directed evolution. We have developed a more efficient method for the subcloning of DNA-shuffled libraries by employing recombination cloning (Gateway). The Gateway cloning procedure was performed directly after the gene reassembly reaction, without additional purification and amplification steps, thus simplifying the conventional DNA shuffling protocols. Recombination-based cloning, directly from the heterologous reassembly reaction, conserved the high quality of the library and reduced the time required for the library construction. The described method is generally compatible for the construction of DNA-shuffled gene libraries. © The Author 2014. Published by Oxford University Press. All rights reserved.

Effective connectivity gateways to the Theory of Mind network in processing communicative intention.
Tettamanti, Marco; Vaghi, Matilde M; Bara, Bruno G; Cappa, Stefano F; Enrici, Ivan; Adenzato, Mauro
2017-07-15
An Intention Processing Network (IPN), involving the medial prefrontal cortex, precuneus, bilateral posterior superior temporal sulcus, and temporoparietal junctions, plays a fundamental role in comprehending intentions underlying action goals. In a previous fMRI study, we showed that, depending on the linguistic or extralinguistic (gestural) modality used to convey the intention, the IPN is complemented by activation of additional brain areas, reflecting distinct modality-specific input gateways to the IPN. These areas involve, for the linguistic modality, the left inferior frontal gyrus (LIFG), and for the extralinguistic modality, the right inferior frontal gyrus (RIFG). Here, we tested the modality-specific gateway hypothesis, by using DCM to measure inter-regional functional integration dynamics between the IPN and LIFG/RIFG gateways. We found strong evidence of a well-defined effective connectivity architecture mediating the functional integration between the IPN and the inferior frontal cortices. The connectivity dynamics indicate a modality-specific propagation of stimulus information from LIFG to IPN for the linguistic modality, and from RIFG to IPN for the extralinguistic modality. Thus, we suggest a functional model in which the modality-specific gateways mediate the structural and semantic decoding of the stimuli, and allow for the modality-specific communicative information to be integrated in Theory of Mind inferences elaborated through the IPN.

Child development and pediatric sport and recreational injuries by age.
Schwebel, David C; Brezausek, Carl M
2014-01-01
In 2010, 8.6 million children were treated for unintentional injuries in American emergency departments. Child engagement in sports and recreation offers many health benefits but also exposure to injury risks. In this analysis, we consider possible developmental risk factors in a review of age, sex, and incidence of 39 sport and recreational injuries. To assess (1) how the incidence of 39 sport and recreational injuries changed through each year of child and adolescent development, ages 1 to 18 years, and (2) sex differences. Design : Descriptive epidemiology study. Emergency department visits across the United States, as reported in the 2001-2008 National Electronic Injury Surveillance System database. Data represent population-wide emergency department visits in the United States. Main Outcome Measure(s) : Pediatric sport- and recreation-related injuries requiring treatment in hospital emergency departments. Almost 37 pediatric sport or recreational injuries are treated hourly in the United States. The incidence of sport- and recreation-related injuries peaks at widely different ages. Team-sport injuries tend to peak in the middle teen years, playground injuries peak in the early elementary ages and then drop off slowly, and bicycling injuries peak in the preteen years but are a common cause of injury throughout childhood and adolescence. Bowling injuries peaked at the earliest age (4 years), and injuries linked to camping and personal watercraft peaked at the oldest age (18 years). The 5 most common causes of sport and recreational injuries across development, in order, were basketball, football, bicycling, playgrounds, and soccer. Sex disparities were common in the incidence of pediatric sport and recreational injuries. Both biological and sociocultural factors likely influence the developmental aspects of pediatric sport and recreational injury risk. Biologically, changes in perception, cognition, and motor control might influence injury risk. Socioculturally

Experimental evaluation of BZ-GW (BACnet-ZigBee smart grid gateway) for demand response in buildings
International Nuclear Information System (INIS)
Hong, Seung Ho; Kim, Se Hwan; Kim, Gi Myung; Kim, Hyung Lae
2014-01-01
The SG (smart grid) is a modernized and a future-oriented electric grid that deals with the whole energy chain, from generation to consumer. Among the SG applications, DR (demand response) is an important control mechanism to manage the electricity consumption of the customer in response to supply conditions. In buildings, DR is managed through installed communication networks which support DR applications. BACnet is an international standard communication protocol for building automation and control systems. BACnet uses ZigBee as a wireless communication protocol. Both BACnet and ZigBee have their own DR applications. In this study, we developed a BACnet-ZigBee gateway that maps the DR application of BACnet to that of ZigBee and vice versa. In addition, we developed an experimental facility to demonstrate how the BACnet-ZigBee gateway can be implemented for DR applications in buildings. We also measured the communication delay to verify that the BZ-GW (BACnet-ZigBee smart grid gateway) developed here satisfies the requirements of real-time DR service in buildings. - Highlights: • Developed a gateway that maps the DR application of BACnet to that of ZigBee. • Verified satisfaction for real-time requirement using experimental facility. • The gateway and other device will play a infrastructure role in buildings. • The implementation method could become a reference model for future similar

Outdoor recreation is one of many important benefits provided by public lands. Data on recreational use are critical for informing management of recreation resources, however, managers often lack actionable information on visitor use for large protected areas that lack controlled access points. The purpose of this study is to explore the potential for social media data (e.g., geotagged images shared on Flickr and trip reports shared on a hiking forum) to provide land managers with useful measures of recreational use to dispersed areas, and to provide lessons learned from comparing several more traditional counting methods. First, we measure daily and monthly visitation rates to individual trails within the Mount Baker-Snoqualmie National Forest (MBSNF) in western Washington. At 15 trailheads, we compare counts of hikers from infrared sensors, timelapse cameras, and manual on-site counts, to counts based on the number of shared geotagged images and trip reports from those locations. Second, we measure visitation rates to each National Forest System (NFS) unit across the US and compare annual measurements derived from the number of geotagged images to estimates from the US Forest Service National Visitor Use Monitoring Program. At both the NFS unit and the individual-trail scales, we found strong correlations between traditional measures of recreational use and measures based on user-generated content shared on the internet. For national forests in every region of the country, correlations between official Forest Service statistics and geotagged images ranged between 55% and 95%. For individual trails within the MBSNF, monthly visitor counts from on-site measurements were strongly correlated with counts from geotagged images (79%) and trip reports (91%). The convenient, cost-efficient and timely nature of collecting and analyzing user-generated data could allow land managers to monitor use over different seasons of the year and at sites and scales never previously

The nexus of fun and nutrition: Recreational fishing is also about food
Cooke, Steven J.; Twardek, William M.; Lennox, Robert J.; Zolderdo, Aaron J.; Bower, Shannon D.; Gutowsky, Lee F. G.; Danylchuk, Andy J.; Arlinghaus, Robert; Beard, Douglas

Recreational fishing is a popular activity in aquatic ecosystems around the globe using a variety of gears including rod and line and to a lesser extent handlines, spears, bow and arrow, traps and nets. Similar to the propensity to engage in voluntary catch-and-release, the propensity to harvest fishes strongly varies among cultures, locations, species and fisheries. There is a misconception that because recreational fishing happens during non-work (i.e. leisure) time, the nutritional motivation is negligible; therefore, the role of recreational fishing in supporting nutrition (and thus food security) at regional, national or global scales is underappreciated. We consider the factors that influence whether fish will be harvested or released by examining the motives that underlie recreational fishing. Next, we provide an overview of the magnitude and role of recreational fishing harvest in supporting nutrition using regional case-studies. Then, we address issues such as contaminants and parasites that constrain the ability of fish harvested by recreational fishers to be consumed. Although recreational fishing is foremost a leisure activity, the harvest of fish for personal consumption by recreational fishers has contributed and will continue to contribute to human nutrition by providing an accessible, affordable and generally highly sustainable food source, notwithstanding concerns about food safety and possibly overfishing. Attempts to better quantify the role of fish harvested by recreational fishers and the relative contribution to overall food security and personal nutrition will provide resource managers and policymakers the information needed to guide management activities and policy development.

A personal best marathon time has been reported as a strong predictor variable for an Ironman race time in recreational female Ironman triathletes. This raises the question whether recreational female Ironman triathletes are similar to recreational female marathoners. We investigated similarities and differences in anthropometry and training between 53 recreational female Ironman triathletes and 46 recreational female marathoners. The association of anthropometric variables and training characteristics with race time was investigated using bi- and multi-variate analysis. The Ironman triathletes were younger (P marathoners. Overall weekly training hours were higher in the Ironman triathletes (P marathoners (P marathon split time for the Ironman triathletes (P = 0.01) and to marathon race time for the marathoners (P = 0.01). To conclude, although personal best marathon time is a strong predictor variable for performance in recreational female Ironman triathletes, there are differences in both anthropometry and training between recreational female Ironman triathletes and recreational female marathoners and different predictor variables for race performance in these two groups of athletes. These findings suggest that recreational female Ironman triathletes are not comparable to recreational female marathoners regarding the association between anthropometric and training characteristics with race time.

The Cuyahoga River within Cuyahoga Valley National Park (CVNP) is at times impaired for recreational use due to elevated concentrations of Escherichia coli (E. coli), a fecal-indicator bacterium. During the recreational seasons of mid-May through September during 2009–11, samples were collected 4 days per week and analyzed for E. coli concentrations at two sites within CVNP. Other water-quality and environ-mental data, including turbidity, rainfall, and streamflow, were measured and (or) tabulated for analysis. Regression models developed to predict recreational water quality in the river were implemented during the recreational seasons of 2009–11 for one site within CVNP–Jaite. For the 2009 and 2010 seasons, the regression models were better at predicting exceedances of Ohio's single-sample standard for primary-contact recreation compared to the traditional method of using the previous day's E. coli concentration. During 2009, the regression model was based on data collected during 2005 through 2008, excluding available 2004 data. The resulting model for 2009 did not perform as well as expected (based on the calibration data set) and tended to overestimate concentrations (correct responses at 69 percent). During 2010, the regression model was based on data collected during 2004 through 2009, including all of the available data. The 2010 model performed well, correctly predicting 89 percent of the samples above or below the single-sample standard, even though the predictions tended to be lower than actual sample concentrations. During 2011, the regression model was based on data collected during 2004 through 2010 and tended to overestimate concentrations. The 2011 model did not perform as well as the traditional method or as expected, based on the calibration dataset (correct responses at 56 percent). At a second site—Lock 29, approximately 5 river miles upstream from Jaite, a regression model based on data collected at the site during the recreational

The microbiological water quality of a 23-mile segment of the Cuyahoga River within the Cuyahoga Valley National Park was examined in this study. This segment of the river receives discharges of contaminated water from stormwater, combined-sewer overflows, and incompletely disinfected wastewater. Frequent exceedances of Ohio microbiological water-quality standards result in a health risk to the public who use the river for water-contact recreation. Water samples were collected during the recreational season of May through October at four sites on the Cuyahoga River in 2000, at three sites on the river in 2002, and from the effluent of the Akron Water Pollution Control Station (WPCS) both years. The samples were collected over a similar range in streamflow in 2000 and 2002. Samples were analyzed for physical and chemical constituents, as well as the following microbiological indicators and pathogenic organisms: Escherichia coli (E. coli), Salmonella, F-specific and somatic coliphage, enterovirus, infectious enterovirus, hepatitis A virus, Clostridium perfringens (C. perfringens), Cryptosporidium, and Giardia. The relations of the microorganisms to each other and to selected water-quality measures were examined. All microorganisms analyzed for, except Cryptosporidium, were detected at least once at each sampling site. Concentrations of E. coli exceeded the Ohio primary-contact recreational standard (298 colonies per 100 milliliters) in approximately 87 percent of the river samples and generally were higher in the river samples than in the effluent samples. C. perfringens concentrations were positively and significantly correlated with E. coli concentrations in the river samples and generally were higher in the effluent samples than in the river samples. Several of the river samples that met the Ohio E. coli secondary-contact recreational standard (576 colonies per 100 milliliters) had detections of enterovirus, infectious enterovirus, hepatitis A virus, and

Physical and numerical modelling is becoming of increasing importance in volcanology and volcanic hazard assessment. However, new interdisciplinary problems arise when dealing with complex mathematical formulations, numerical algorithms and their implementations on modern computer architectures. Therefore new frameworks are needed for sharing knowledge, software codes, and datasets among scientists. Here we present the Volcano Modelling and Simulation gateway (VMSg, accessible at http://vmsg.pi.ingv.it), a new electronic infrastructure for promoting knowledge growth and transfer in the field of volcanological modelling and numerical simulation. The new web portal, developed in the framework of former and ongoing national and European projects, is based on a dynamic Content Manager System (CMS) and was developed to host and present numerical models of the main volcanic processes and relationships including magma properties, magma chamber dynamics, conduit flow, plume dynamics, pyroclastic flows, lava flows, etc. Model applications, numerical code documentation, simulation datasets as well as model validation and calibration test-cases are also part of the gateway material.

An approach for recreation suitability analysis to recreation planning in Gölcük Nature Park.
Gül, Atila; Orücü, M Kamil; Karaca, Oznur
2006-05-01
Gölcük Nature Park (GNP) is an area protected by law in Turkey. It is an important nature park with rich flora, fauna, geomorphologic forms, landscape features, and recreational potential in the region. However, GNP does not have a recreation management plan. The purpose of this study was to determine the actual natural, cultural, and visual resources of GNP, determine the most suitable recreational sites with multiple factors, evaluate the demands and tendencies of visitors, and suggest recreational activities and facilities for the most suitable sites of GNP. However, it was also conceived as leading to a recreational plan and design of GNP in the future and identifying the entire appropriate and current data of GNP with the creation of various maps. This study used multifactor analysis to determine the most suitable recreation sites of GNP. Used recreation factors were established including degree of slope, proximity to water resources, accessibility, elevation, vegetation, soil, climate, aspect, current cultural facilities, visual values, and some limiting factors in accordance with the characteristics of GNP. Weighting and suitability values of factors were determined by 30 local expert surveys. All obtained data were evaluated and integrated in the Geographical Information Systems base. Obtained maps were overlapped. Thus, recreational suitability zones map were created manually. However, the demands and behaviours from visitor surveys in GNP were focused on the most suitable recreation sites of the park. Finally, 10% of GNP was identified as the most suitable sites for recreational use. Various recreational facilities and activities (including picnicking, sports facilities and playgrounds, camping sites, walking paths, food and local outlets, etc.) were recommended for nine of the most suitable areas on the proposed recreational map.

To study potential effects of recreation activity on habitat use of desert bighorn sheep (Ovis canadensis nelsoni), we placed Global Positioning System collars on 10 female bighorn sheep within the Wonderland of Rocks–Queen Mountain region of Joshua Tree National Park (JOTR), California, USA, from 2002 to 2004. Recreation use was highest from March to April and during weekends throughout the year. Daily use of recreation trails was highest during midday. By comparing habitat use (slope, ruggedness, distance to water, and distance to recreation trails) of female bighorn sheep on weekdays versus weekends, we were able to detect short-term shifts in behavior in response to recreation. In a logistic regression of bighorn sheep locations versus random locations for March and April, female locations at midday (1200 hours) were significantly more distant from recreation trails on weekends compared with weekdays. Our results indicate that within this region of JOTR, moderate to high levels of human recreation activity may temporarily exclude bighorn females from their preferred habitat. However, the relative proximity of females to recreation trails during the weekdays before and after such habitat shifts indicates that these anthropogenic impacts were short-lived. Our results have implications for management of wildlife on public lands where the co-existence of wildlife and recreational use is a major goal.

Gateway to the Syriac Saints: A Database Project
Directory of Open Access Journals (Sweden)
Jeanne-Nicole Mellon Saint-Laurent
2016-04-01
Full Text Available This article describes The Gateway to the Syriac Saints, a database project developed by the Syriac Reference Portal (www.syriaca.org. It is a research tool for the study of Syriac saints and hagiographic texts. The Gateway to the Syriac Saints is a two-volume database: 1 Qadishe and 2 Bibliotheca Hagiographica Syriaca Electronica (BHSE. Hagiography, the lives of the saints, is a multiform genre. It contains elements of myth, history, biblical exegesis, romance, and theology. The production of saints’ lives blossomed in late antiquity alongside the growth of the cult of the saints. Scholars have attended to hagiographic traditions in Greek and Latin, but many scholars have yet to discover the richness of Syriac hagiographic literature: the stories, homilies, and hymns on the saints that Christians of the Middle East told and preserved. It is our hope that our database will give scholars and students increased access to these traditions to generate new scholarship. The first volume, Qadishe or “saints” in Syriac, is a digital catalogue of saints or holy persons venerated in the Syriac tradition. Some saints are native to the Syriac-speaking milieu, whereas others come from other linguistic or cultural traditions. Through the translation of their hagiographies and the diffusion of saints’ cults in the late antique world, saints were adopted, “imported,” and appropriated into Syriac religious memory. The second volume, the BHSE, focuses on Syriac hagiographic texts. The BHSE contains the titles of over 1000 Syriac stories, hymns, and homilies on saints. It also includes authors’ or hagiographers’ names, the first and last lines of the texts (in Syriac, English, and French, bibliographic information, and the names of the manuscripts containing these hagiographic works. We have also listed modern and ancient translations of these works. All of the data in the Gateway to the Syriac Saints has been encoded in TEI, and it is fully

Full Text Available Recreational architecture is a branch of architectural activity whose main object is formation of recreational spaces (territories, buildings, complexes and equipment. The goal of recreational architecture is to create optimal (comfortable, lovely and realizable environment for all recreation types and forms. This goal is realized by projects which are based on scientific research and recommendations. This activity needs more than casual work and living environment. It needs special space and equipment: territory, water area, buildings, and rooms. Everything can be called recreational environment. Recreational environment can be of various dimensional scales: enormous seaside or lake areas intended for recreation, resorts, recreational institution complexes and many single buildings, beaches, forest parks, pools. Recreational environment is possible not only out of town but in town as well. Beginning of recreational architecture is observed in antique cultures, but as a separate specific architectural activity branch it rapidly began to spread in last century first half and in Lithuania – in the last four decades. In this work, analysis of evaluating recreational architecture is made seeking to reveal recreational architecture evaluating criteria and their use .Article in Lithuanian

Full Text Available The recreation areas are composed of environmental matrices primary contact with the population (water and sand and therefore need to be periodically monitored, because pathogenic microorganisms can be found that offer risks to human and animal health. This study aimed to develop critical topics in environmental sanitation as use of water and sand in recreation places, biomarkers associated with health risks, diseases caused by exposure to contaminated environmental matrices and indicate the importance of bioindicators in laws that underpin the supervisory board, to secure the most complete monitoring and give support the actions of environmental control and health agencies. The literature review was used as instrumental to the research. In Brazil, the acceptable limits standards are described in Resolution by National Environmental Council for coliforms present in bathing water, but not exist to sand matrix. Only isolated initiatives of municipal environmental agencies have established limits for the classification of sand matrix, based on only bacteriological parameters. Concluded that scientific studies may support others biomarkers of sanitary conditions are being conducted in Brazil, proposing fungi and parasites in evaluating the sanitary quality of recreation areas.

Full Text Available Abstract Background Recombinatorial cloning using the GatewayTM technology has been the method of choice for high-throughput omics projects, resulting in the availability of entire ORFeomes in GatewayTM compatible vectors. The MultiSite GatewayTM system allows combining multiple genetic fragments such as promoter, ORF and epitope tag in one single reaction. To date, this technology has not been accessible in the yeast Saccharomyces cerevisiae, one of the most widely used experimental systems in molecular biology, due to the lack of appropriate destination vectors. Results Here, we present a set of three-fragment MultiSite GatewayTM destination vectors that have been developed for gene expression in S. cerevisiae and that allow the assembly of any promoter, open reading frame, epitope tag arrangement in combination with any of four auxotrophic markers and three distinct replication mechanisms. As an example of its applicability, we used yeast three-hybrid to provide evidence for the assembly of a ternary complex of plant proteins involved in jasmonate signalling and consisting of the JAZ, NINJA and TOPLESS proteins. Conclusion Our vectors make MultiSite GatewayTM cloning accessible in S. cerevisiae and implement a fast and versatile cloning method for the high-throughput functional analysis of (heterologous proteins in one of the most widely used model organisms for molecular biology research.

The National Park Service (NPS) organized more than 270 parks with important natural resources into 32 ecoregional networks to conduct Inventory and Monitoring (I&M) activities for assessment of natural resources within park units. The Missouri National Recreational River (NRR) is among the 13 parks in the NPS Northern Great Plain Network (NGPN). Park managers and NGPN staff identified surface water resources as a high priority vital sign to monitor in park units. The objectives for the Missouri NRR water quality sampling design are to (1) assess the current status and long-term trends of select water quality parameters; and (2) document trends in streamflow at high-priority stream systems. Due to the large size of the Missouri River main stem, the NGPN water quality design for the Missouri NRR focuses on wadeable tributaries within the park unit. To correlate with the NGPN water quality protocols, monitoring of the Missouri NRR consists of measurement of field core parameters including dissolved oxygen, pH, specific conductance, and temperature; and streamflow. The purpose of this document is to discuss factors examined for selection of water quality monitoring on segments of the Missouri River tributaries within the Missouri NRR.Awareness of the complex history of the Missouri NRR aids in the current understanding and direction for designing a monitoring plan. Historical and current monitoring data from agencies and entities were examined to assess potential NGPN monitoring sites. In addition, the U.S. Environmental Protection Agency 303(d) list was examined for the impaired segments on tributaries to the Missouri River main stem. Because major tributaries integrate water quality effects from complex combinations of land use and environmental settings within contributing areas, a 20-mile buffer of the Missouri NRR was used to establish environmental settings that may impact the water quality of tributaries that feed the Missouri River main stem.

Public perceptions of arguments supporting and opposing recreational marijuana legalization.
McGinty, Emma E; Niederdeppe, Jeff; Heley, Kathryn; Barry, Colleen L
2017-06-01
In debates about recreational marijuana legalization, pro-legalization arguments highlighting economic and other potential policy benefits compete with anti-legalization arguments emphasizing public health risks. In 2016, we conducted a national survey using an online panel (N=979) designed to answer two main research questions: (1) How do Americans perceive the relative strength of competing arguments about recreational marijuana legalization? (2) How are perceptions of argument strength associated with public support for recreational marijuana legalization? We examined differences in attitudes among individuals living in states that have/have not legalized recreational marijuana and among Democrats/Independents/Republicans. Ordered logit regression assessed the relationship between perceived argument strength and public support for recreational marijuana legalization. Respondents rated pro-legalization arguments highlighting beneficial economic and criminal justice consequences as more persuasive than anti-legalization arguments emphasizing adverse public health effects. Respondents were more likely to agree with arguments highlighting legalization's potential to increase tax revenue (63.9%) and reduce prison overcrowding (62.8%) than arguments emphasizing negative consequences on motor vehicle crashes (51.8%) and youth health (49.6%). The highest rated anti-legalization arguments highlighted the conflict between state and federal marijuana laws (63.0%) and asserted that legalization will fail to eliminate the black market (57.2%). Respondents who endorsed pro-legalization economic and criminal justice arguments were more likely than other respondents to support legalization. Our findings indicate that, on both side of the recreational marijuana legalization debate, there are arguments that resonate with the American public. However, public health risk messages were viewed as less compelling than pro-legalization economic and criminal justice-oriented arguments

Recreation-induced changes in boreal bird communities in protected areas.
Kangas, K; Luoto, M; Ihantola, A; Tomppo, E; Siikamäki, P
2010-09-01
The impacts of human-induced disturbance on birds have been studied in growing extent, but there are relatively few studies about the effects of recreation on forest bird communities in protected areas. In this paper, the relative importance of recreation as well as environmental variables on bird communities in Oulanka National Park, in northeastern Finland, was investigated using general additive models (GAM). Bird data collected using the line transect method along hiking trails and in undisturbed control areas were related to number of visits, area of tourism infrastructure, and habitat variables. We further examined the impact of spatial autocorrelation by calculating an autocovariate term for GAMs. Our results indicate that number of visits affects the occurrence and composition of bird communities, but it had no impact on total species richness. Open-cup nesters breeding on the ground showed strongest negative response to visitor pressure, whereas the open-cup nesters nesting in trees and shrubs were more tolerant. For cavity-nesting species, recreation had no significant impact. The contribution of the number of visits was generally low also in models in which it was selected, and the occurrence of birds was mainly determined by habitat characteristics of the area. However, our results show that the recreation-induced disturbance with relatively low visitor pressure can have negative impacts on some bird species and groups of species and should be considered in management of protected areas with recreational activities.

Full Text Available What are the narrative implications of working through aspects of an identity heritage that may have been partially or wholly lost through a family history of migration or diaspora? How do subjects access dislocated parts of their identity, and which strategies do they employ to (re-create them within their stories? To explore such instances of what I term ‘by proxy’ diasporic experiences, I offer a comparative case study of three novels written by authors with family heritage from the Horn of Africa (Ubah Cristina Ali Farah, Dinaw Mengestu and Nadifa Mohamed, who are now active in different nations and languages. Highlighting the narrative strategies used to bridge the gap between past, present and future in the articulation of identity allows us to grasp the trans-national impact of diaspora mobility on memory work and privileges an awareness of the co-existence of different ‘pasts’ within national contexts.This article is published under a CC-BY license https://creativecommons.org/licenses/by/3.0/

Environmental auditing: Capabilities and management utility of recreation impact monitoring programs
Marion, J.L.
1995-01-01
A recreation impact monitoring system was developed and applied in 1984?1986 and in 1991 to all backcountry river-accessed campsites within Delaware Water Gap National Recreation Area, Pennsylvania and New Jersey. Results suggest that actions implemented by park managers in response to problems identified by the initial survey were highly effective in reducing resource degradation caused by camping. In particular, the elimination of some designated campsites and installation of anchored firegrates reduced the total area of disturbance by 50%. Firegrate installation provided a focal point that increased the concentration of camping activities, allowing peripheral areas to recover. As suggested by predictive models, additional resource degradation caused by increased camping intensities is more than offset by improvements in the condition of areas where use is eliminated. The capabilities and management utility of recreation impact monitoring programs, illustrated by the Delaware Water Gap monitoring program, are also presented and discussed.

2009-04-01
Full Text Available Urban people not only attempt to satisfy their hunger for nature by performing some recreational activities in natural areas in their proximities but also they challenge to regain disappeared natural areas in and around their cities in order to make residential areas more liveable. When considered the conditions today, urban trees and forests have turned out to be obligatory facilities for urban people since they provide not only recreational services but also contributions to city aesthetics, public health (with clean air and oxygen supply, human psychology, city and national economy and urban ecology. In this study, it was aimed to determine the existent recreational potentials of Kafkasör urban forest in Artvin city by evaluating the recreational conditions of urban forests. For this aim, recreational value of Artvin Urban Forest tried to be calculated according to Gülez’s method in order to determine existent potentials of recreational areas. As the result of the study, it was found that recreational potential rate of the area was 66.9 %, which shows the area has high recreational potential. The most important factor affecting this high potential was found to be the landscape characteristics the area has and recreational facilities the area provides.

SCORPION II persistent surveillance system with universal gateway
Coster, Michael; Chambers, Jonathan; Brunck, Albert
2009-05-01
This paper addresses improvements and benefits derived from the next generation Northrop Grumman SCORPION II family of persistent surveillance and target recognition systems produced by the Xetron campus in Cincinnati, Ohio. SCORPION II reduces the size, weight, and cost of all SCORPION components in a flexible, field programmable system that is easier to conceal, backward compatible, and enables integration of over forty Unattended Ground Sensor (UGS) and camera types from a variety of manufacturers, with a modular approach to supporting multiple Line of Sight (LOS) and Beyond Line of Sight (BLOS) communications interfaces. Since 1998 Northrop Grumman has been integrating best in class sensors with its proven universal modular Gateway to provide encrypted data exfiltration to Common Operational Picture (COP) systems and remote sensor command and control. In addition to being fed to COP systems, SCORPION and SCORPION II data can be directly processed using a common sensor status graphical user interface (GUI) that allows for viewing and analysis of images and sensor data from up to seven hundred SCORPION system Gateways on single or multiple displays. This GUI enables a large amount of sensor data and imagery to be used for actionable intelligence as well as remote sensor command and control by a minimum number of analysts.

Sport and active recreation injuries in Australia: evidence from emergency department presentations.
Finch, C; Valuri, G; Ozanne-Smith, J
1998-09-01
Despite the rise in specialist clinical services for the management of sports and active recreation injury, many patients attend hospital emergency departments for treatment. The purpose of this study was to describe sports injury cases presented to selected hospital emergency departments around Australia for the period 1989-1993. Routinely collected emergency department injury presentation data from the Australian National Injury Surveillance Unit were examined. Data on 98,040 sports and active recreation emergency department presentations were analysed. Sports and active recreation activities were ranked according to frequency of presentation. Relative proportions of injury type and body region injured were determined. Data are presented separately for children (15 years of age). Among the 10 activities that most commonly led to a sports or active recreation injury presentation for all ages were cycling, Australian football, basketball, soccer, cricket, netball, and rugby. For children, injuries were also commonly associated with roller skating/blading, skateboarding, and trampolining. Hockey, martial arts, and dancing injuries were frequent in adults. Most sporting injuries occurred during organised competition or practice whereas the active recreation injuries occurred in a variety of settings. Fractures, strains, and sprains, particularly to the lower and upper extremities, were common types of injury. The rich, but nevertheless limited, information available about sports and active recreation injuries from data collected in emergency departments indicates that these activities are a common context for injury at the community level in Australia.

An Ecosystem Approach to Recreation Location Quotients
Directory of Open Access Journals (Sweden)
Mary Vogel
2011-12-01
Full Text Available Despite the widespread agreement on the importance of preserving ecological integrity in conservation and outdoor recreation decision-making processes, traditional metrics analyzing the supply of and demand for conservation and recreation resources have focused on geographical and population-centric units of measurement rather than ecological ones. One tool past researchers have used to inform recreation resource planning is the recreation location quotient (RLQ. While simple park-to-population ratios or acres-per-capita metrics provide a base measure of carrying capacity and are often useful to set broad recreation supply standards, the RLQ offers a more nuanced snapshot of supply and demand by comparing regional ratios to a standardized reference region. The RLQ is thus able to provide a statistic or quotient that highlights regions where recreation resources are particularly abundant and/or scarce relative to a reference area. This project expands the past RLQ analyses by investigating the distribution of recreation resources across the 10 ecological sections found within the US state of Minnesota. RLQs were calculated using recreation trail mileage, natural resource and recreation area acreage data, and recreation facility data from federal, state, and local agencies. Results found notable differences in supply of recreation resources across ecological sections. Some sections were considerably underrepresented in recreation resources-per area (e.g., Red River Valley and North Central Glaciated Plains while others were underrepresented in recreation resources-per capita (e.g., Minnesota and Northeast Iowa Morainal. The RLQ statistics and resulting maps illustrating relative surplus or deficiencies can inform future land acquisition decisions and highlight the need for cross-jurisdictional planning in order to ensure outdoor recreation systems are ecologically representative. Possible implications and recommendations for future planning

National Identity and Migration in an Emerging Gateway Community
Directory of Open Access Journals (Sweden)
Jennifer Byrne
2018-04-01
Full Text Available This paper examines how conceptions of national and local identity influence reactions to migration in the Shenandoah Valley, a rural location in Southwest Virginia with unique demographic characteristics. While Shenandoah Valley residents have been predominantly non-Hispanic whites of European descent, a recent visible influx of Hispanic laborers, a higher than national average Muslim population, a history of refugee resettlement and the migration of urbanites from Northern Virginia have made the Valley one of the most diverse locations in the state of Virginia today. Using a qualitative methods approach with both apriori and emergent coding, I offer some insights as to how a traditional ethnic and civic framework of national identity and emergent themes of local identity, including family values and traditionalism, influence reactions to the changing demographics in this rural community.

Recreational marijuana legalization and college student use: Early evidence.
Miller, Austin M; Rosenman, Robert; Cowan, Benjamin W
2017-12-01
We analyze marijuana use by college undergraduates before and after legalization of recreational marijuana. Using survey data from the National College Health Assessment, we show that students at Washington State University experienced a significant increase in marijuana use after legalization. This increase is larger than would be predicted by national trends. The change is strongest among females, Black students, and Hispanic students. The increase for underage students is as much as for legal-age students. We find no corresponding changes in the consumption of tobacco, alcohol, or other drugs.

The coal seams of Guengcun Coal mine of Yima Coal Group Co. Ltd. are prone to spontaneous combustion. Fully mechanized longwall mining with sublevel caving is used as the mining method. Based on the characteristics of the gateways of the 1301 coal face and of the roof coal seams, the natural equilibrium arch theory was used to design the parameters of 11 mine-type metal supports. Then, in-situ supporting experiments were carried out. The results indicate that under the action of virgin rock stress, the width of broken rocks zone of surrounding rocks is 1.7-2.0 m in the return heading and 1.1-1.3 m in the outgoing headway and their surrounding rocks belong to the IV-type soft rock and the III-type common surrounding rock respectively. Therefore, under the movable abutment pressure, the gateway deformation is serious. At the same time, the accumulated water on gateway floor must be drained in time. These measures were taken in the 1302 and 1304 coal faces in Gengcun colliery, and satisfactory results have been obtained. 8 refs., 3 figs.

Background Valuable clone collections encoding the complete ORFeomes for some model organisms have been constructed following the completion of their genome sequencing projects. These libraries are based on Gateway cloning technology, which facilitates the study of protein function by simplifying the subcloning of open reading frames (ORF) into any suitable destination vector. The expression of proteins of interest as fusions with functional modules is a frequent approach in their initial functional characterization. A limited number of Gateway destination expression vectors allow the construction of fusion proteins from ORFeome-derived sequences, but they are restricted to the possibilities offered by their inbuilt functional modules and their pre-defined model organism-specificity. Thus, the availability of cloning systems that overcome these limitations would be highly advantageous. Results We present a versatile cloning toolkit for constructing fully-customizable three-part fusion proteins based on the MultiSite Gateway cloning system. The fusion protein components are encoded in the three plasmids integral to the kit. These can recombine with any purposely-engineered destination vector that uses a heterologous promoter external to the Gateway cassette, leading to the in-frame cloning of an ORF of interest flanked by two functional modules. In contrast to previous systems, a third part becomes available for peptide-encoding as it no longer needs to contain a promoter, resulting in an increased number of possible fusion combinations. We have constructed the kit’s component plasmids and demonstrate its functionality by providing proof-of-principle data on the expression of prototype fluorescent fusions in transiently-transfected cells. Conclusions We have developed a toolkit for creating fusion proteins with customized N- and C-term modules from Gateway entry clones encoding ORFs of interest. Importantly, our method allows entry clones obtained from ORFeome

Recreational drugs. Societal and professional issues.
Solari-Twadell, P A
1991-06-01
Recreational drug use presents a challenge to society and, in particular, the profession of nursing. Recreational drug use must be appreciated for the implications it presents for the episodes of abuse and development of chronic health problems. The effects and recreational use of volatile substances, cannabis, opioids, barbiturates, benzodiazepines, amphetamines, cocaine, psychedelics, and designer drugs as well as alcohol, caffeine, and nicotine must be acknowledged and understood if options for change are to be considered. The resultant cost of recreational drug use as well as health care implications, public safety, and prevention are significant issues society is faced with today. These issues will continue to be significant unless the current posture toward recreational drug use and abuse is addressed. The profession of nursing continues to be faced with the problems associated with recreational drug use not only through caring for clients, but immediately by the effects of recreational drug use on individual professional nurses. To respond effectively, nursing education and nursing research must be challenged to create an emphasis on this focus. Only through this type of multifocal approach will long-term substantial change be affected for the betterment of future generations.

Full Text Available During recent years in Korea, the participants in outdoor recreation have significantly increased, and relevant industries have also shown a great growth. This phenomenon is to pursue outdoor recreation based on nature as a way of maintaining healthy lifestyle. This study aimed to explore how perceived restorative environment influences wellness, satisfaction, and loyalty by researching climbers in the National Park. The data were collected at four times only on weekends from 12th July to 20th July 2014 at the entrance of Mt. Dobong in Mt. Bukhand National Park in Seoul. Researchers selected every 5th visitors with systematic sampling. Out of 420 collected questionnaires, except from 20 questionnaires which include unanswered items, 400 questionnaires were used for empirical analysis. The result of the analysis by using SEM shows that perceived restorative environment has a critical influence on wellness, and this wellness also affects satisfaction and loyalty. This result of the research provides a useful insight into how policy makers and practitioners in the National Parks, urban parks and Ministry of Health and Welfare develop the places for outdoor recreation based on nature in order to pursue wellness as a way of the improvement of the public health.

The Tourist and Recreation Potential of Historical Cities in North-West Russia
Directory of Open Access Journals (Sweden)
Hodachek V. M.
2017-12-01
Full Text Available In recent years, the development of historical cities has been high on research agenda. This is explained by the growing role of tourism and recreation in socioeconomic development and the persisting problem of the national economy’s spatial organisation amidst the absence of a clear-cut regional policy. The authors stress the discrepancy between the distribution of economic activities and the established system of settlement. This is particularly true for many historical cities, whose economic resources have been curtailed. This study provides a rationale for a more efficient use of the tourist and recreational potential to boost the socio-economic development of Russia’s historical cities. The article describes problems of the cities’ development using the country’s North-West as an example. The authors explore factors behind the formation of a new development strategy for historical cities and analyse conditions necessary for the efficient exploitation of the historical cities’ tourism and recreation potential. The findings obtained suggest that strategic areas of tourism and recreation development in Russia’s historical cities should be identified depending on city type, development conditions and other relevant factors.

Fog computing extends cloud computing to the edge of a network enabling new Internet of Things (IoT) applications and services, which may involve critical data that require privacy and security. In an IoT fog computing system, three elements can be distinguished: IoT nodes that collect data, the cloud, and interconnected IoT gateways that exchange messages with the IoT nodes and with the cloud. This article focuses on securing IoT gateways, which are assumed to be constrained in terms of computational resources, but that are able to offload some processing from the cloud and to reduce the latency in the responses to the IoT nodes. However, it is usually taken for granted that IoT gateways have direct access to the electrical grid, which is not always the case: in mission-critical applications like natural disaster relief or environmental monitoring, it is common to deploy IoT nodes and gateways in large areas where electricity comes from solar or wind energy that charge the batteries that power every device. In this article, how to secure IoT gateway communications while minimizing power consumption is analyzed. The throughput and power consumption of Rivest-Shamir-Adleman (RSA) and Elliptic Curve Cryptography (ECC) are considered, since they are really popular, but have not been thoroughly analyzed when applied to IoT scenarios. Moreover, the most widespread Transport Layer Security (TLS) cipher suites use RSA as the main public key-exchange algorithm, but the key sizes needed are not practical for most IoT devices and cannot be scaled to high security levels. In contrast, ECC represents a much lighter and scalable alternative. Thus, RSA and ECC are compared for equivalent security levels, and power consumption and data throughput are measured using a testbed of IoT gateways. The measurements obtained indicate that, in the specific fog computing scenario proposed, ECC is clearly a much better alternative than RSA, obtaining energy consumption reductions of up to

Does Zoning Winter Recreationists Reduce Recreation Conflict?
Miller, Aubrey D.; Vaske, Jerry J.; Squires, John R.; Olson, Lucretia E.; Roberts, Elizabeth K.
2017-01-01
Parks and protected area managers use zoning to decrease interpersonal conflict between recreationists. Zoning, or segregation, of recreation—often by non-motorized and motorized activity—is designed to limit physical interaction while providing recreation opportunities to both groups. This article investigated the effectiveness of zoning to reduce recreation conflict in the Vail Pass Winter Recreation Area in Colorado, USA. Despite a zoning management system, established groomed travel routes were used by both non-motorized recreationists (backcountry skiers, snowboarders, snowshoers) and motorized recreationists (snowmobilers). We hypothesized that persistent recreation conflict reported by non-motorized recreationists was the result of recreation occurring in areas of mixed non-motorized and motorized use, mostly along groomed routes. We performed a geospatial analysis of recreation [from Global Positioning System (GPS) points, n = 1,233,449] in the Vail Pass Winter Recreation Area to identify areas of mixed non-motorized and motorized use. We then surveyed non-motorized recreationists ( n = 199) to test whether reported conflict is higher for respondents who traveled in areas of mixed-use, compared with respondents traveling outside areas of mixed-use. Results from the geospatial analysis showed that only 0.7 % of the Vail Pass Winter Recreation Area contained recreation from both groups, however that area contained 14.8 % of all non-motorized recreation and 49.1 % of all motorized recreation. Survey analysis results showed higher interpersonal conflict for all five standard conflict variables among non-motorized respondents who traveled in areas of mixed-use, compared with those traveling outside mixed-use areas. Management implications and recommendations for increasing the effectiveness of zoning are provided.

Gateways and Water Mass Mixing in the Late Cretaceous North Atlantic
Asgharian Rostami, M.; Martin, E. E.; MacLeod, K. G.; Poulsen, C. J.; Vande Guchte, A.; Haynes, S.
2017-12-01
Regions of intermediate/deep water formation and water-mass mixing in the North Atlantic are poorly defined for the Late Cretaceous, a time of gateway evolution and cooler conditions following the Mid Cretaceous greenhouse. Improved proxy data combined with modeling efforts are required to effectively evaluate the relationship between CO2, paleogeography, and circulation during this cooler interval. We analyzed and compiled latest Cretaceous (79 - 66 Ma) ɛNd and δ13C records from seven bathyal (paleodepths 0.2 - 2 km) and eight abyssal (paleodepths > 2 km) sites in the North Atlantic. Data suggest local downwelling of Northern Component Water (NCW; ɛNd -9.5 and δ13C 1.7 ‰) is the primary source of intermediate/deep water masses in the basin. As this water flows southward and ages, δ13C values decrease and ɛNd values increase; however, additional chemical changes at several sites require mixing with contributions from several additional water masses. Lower ɛNd ( -10) and higher δ13C ( 1.9 ‰) values in the deep NW part of the basin indicate proximal contributions from a region draining old continental crust, potentially representing deep convection following opening of the Labrador Sea. In the deep NE Iberian Basin, higher ɛNd ( -7) and lower δ13C ( 0.8 ‰) during the Campanian suggest mixing with a Tethyan source (ɛNd -7 and δ13C 0.1 ‰) whose importance decreased with restriction of that gateway in the Maastrichtian. Data from bathyal sites suggest additional mixing. In the SE Cape Verde region, observed ɛNd variations from -10 in the Campanian to -13 and -12 in the early and late Maastrichtian, respectively, may record variations in output rates of Tethyan and/or NCW sources and Demerara Bottom Water (ɛNd -16), a proposed warm saline intermediate water mass formed in shallow, equatorial seas. Pacific inflow through the Caribbean gateway impacts intermediate sites at Blake Nose (ɛNd values -8), particularly the shallowest site during the late

Santarém: Gateway City of Historic Frontiers of Western Pará
Directory of Open Access Journals (Sweden)
Scott William Hoefle
2013-07-01
Full Text Available This article treats the historical role of Santarém as a gateway city of multiplefrontiers of the middle valley of the Amazon and valley of the Tapajós Rivers. Over the centuries the city has controlled a hinterland that underwent a number of economic surges, from collecting natural spices, herbs and fruit of the forest in the beginning of the Portuguese colonization to agro-industry today. Located midway between Belém and Manaus, and historically subordinated to these cities, Santarém today has become a regional center for administrative, commercial, cultural and specialized services. The economic surges and socio-environmental transformations are interpreted according to the global cities network model of Peter Taylor, adapted to the Amazon with the concept of gateway cities from the literature on historical frontiers of the world.

Analysis of predictors related to soil contamination in recreational areas of Romania.
Gagiu, C; Pica, E M; Querol, X; Botezan, C S
2015-12-01
Soil contamination in recreational areas can considerably affect children's health, as they are the segment of the population most sensitive to anthropogenic contamination. Soil contamination in recreational areas is influenced by a number of factors such as type and age of the recreational area, nearby traffic intensity, proximity to industrial areas, presence of vegetation, level of usage, treated wood structures, and the extent of maintenance operations carried out in the area. These can most often be observed during a simple site visit. The purpose of the present research is to analyze to which extent the presence of these factors can trigger an alarm signal, highlighting soil contamination in urban recreational areas. In this regard, soil contamination was scaled using the integrated pollution index applied on nine distinctive contaminants (As, Cu, Cd, Zn, Pb, Hg, Co, Ni, Mg) identified using inductively coupled plasma mass spectrometry (ICP-MS). Multiple linear regression analysis was performed in order to assess predictors of soil contamination. The research was carried out in a number of 88 recreational areas, parks, and playgrounds from 19 Romanian cities, revealing the fact that proximity to industrial areas and intensive traffic had statistically significant effects on soil contamination. Furthermore, it was observed that in 78 out of the 88 analyzed locations, the concentrations of contaminants exceeded the guidelines established through national legislation, thus confirming the presumption that high concentrations of contaminants exist in the parks and playgrounds of Romania.

2015-06-01
Full Text Available The subject matter of the research is the tourist and recreation complex of Kabardino-Balkar Republic. The purpose of the work is to provide solutions to problems of the republic tourist and recreation complex development. The results obtained from the study showed that in spite of the fact that in the region’s development certain positive steps are taken, according to the indicators of the tourism and recreation development, the region has not reach the level of the 1990th yet, the possibilities of this major sector of the republic economy remain not demanded. It is highlighted, that the most important factor in the tourist and recreation complex development is its infrastructure condition. It is recommended to use the model of the infrastructure management aimed at providing its effective functioning and development due to formation of interaction system at every power level through a network of the centers of the tourist and recreation complex development. In the article, the need for the use of the innovative approaches for the republic tourist and recreation complex development in the particular development of the new tourist directions are also found. For the purpose to improve the professional training of personnel for the tourism and recreation sphere, the need for a transition to multilevel training of personnel is proved. The main directions of the republic image development on the basis of designing and implementing of the regional program of its image development as the tourist territory and creation of the tourist information center are defined. Realization of all these problems allows to develop a highly effective and competitive tourist and recreation complex in Kabardino-Balkaria.

Casarotti, E.; Spinuso, A.; Matser, J.; Leong, S. H.; Magnoni, F.; Krause, A.; Garcia, C. R.; Muraleedharan, V.; Krischer, L.; Anthes, C.
2014-12-01
The EU-funded project VERCE (Virtual Earthquake and seismology Research Community in Europe) aims to deploy technologies which satisfy the HPC and data-intensive requirements of modern seismology.As a result of VERCE official collaboration with the EU project SCI-BUS, access to computational resources, like local clusters and international infrastructures (EGI and PRACE), is made homogeneous and integrated within a dedicated science gateway based on the gUSE framework. In this presentation we give a detailed overview on the progress achieved with the developments of the VERCE Science Gateway, according to a use-case driven implementation strategy. More specifically, we show how the computational technologies and data services have been integrated within a tool for Seismic Forward Modelling, whose objective is to offer the possibility to performsimulations of seismic waves as a service to the seismological community.We will introduce the interactive components of the OGC map based web interface and how it supports the user with setting up the simulation. We will go through the selection of input data, which are either fetched from federated seismological web services, adopting community standards, or provided by the users themselves by accessing their own document data store. The HPC scientific codes can be selected from a number of waveform simulators, currently available to the seismological community as batch tools or with limited configuration capabilities in their interactive online versions.The results will be staged out via a secure GridFTP transfer to a VERCE data layer managed by iRODS. The provenance information of the simulation will be automatically cataloged by the data layer via NoSQL techonologies.Finally, we will show the example of how the visualisation output of the gateway could be enhanced by the connection with immersive projection technology at the Virtual Reality and Visualisation Centre of Leibniz Supercomputing Centre (LRZ).

Integrating QoS and security functions in an IP-VPN gateway
Fan, Kuo-Pao; Chang, Shu-Hsin; Lin, Kuan-Ming; Pen, Mau-Jy
2001-10-01
IP-based Virtual Private Network becomes more and more popular. It can not only reduce the enterprise communication cost but also increase the revenue of the service provider. The common IP-VPN application types include Intranet VPN, Extranet VPN, and remote access VPN. For the large IP-VPN market, some vendors develop dedicated IP-VPN devices; while some vendors add the VPN functions into their existing network equipment such as router, access gateway, etc. The functions in the IP-VPN device include security, QoS, and management. The common security functions supported are IPSec (IP Security), IKE (Internet Key Exchange), and Firewall. The QoS functions include bandwidth control and packet scheduling. In the management component, policy-based network management is under standardization in IETF. In this paper, we discuss issues on how to integrate the QoS and security functions in an IP-VPN Gateway. We propose three approaches to do this. They are (1) perform Qos first (2) perform IPSec first and (3) reserve fixed bandwidth for IPSec. We also compare the advantages and disadvantages of the three proposed approaches.

2017-01-01
Full Text Available The article is devoted to theoretical analysis of the problems of ecological tourism as a component of the theory and practice of recreational geography (geography, nature. The article reveals the essence and characteristics of ecotourism identifying its issues and determining the direction and tasks of its development. Special attention is paid to types and objects of ecological tourism, main problems and aspects of its development in the context of recreational geography and tourism are highlighted, such as the lack of an overall national concept for the development of rural tourism or the lack of clearly articulated public policies. There are neither standards and regulations applicable to rural tourism nor qualified personnel, knowledge and experience in the service sector of foreign and domestic tourists.There are no regulatory legal acts in the field of rural and ecological tourism which is aggravated by the unwillingness and inability to efficiently use private recreation resources. One of the key problems connected with the development of domestic tourism, including such types as agrotourism (“green tourism”, coupled with the experience of participation in rural works, and rural tourism as a whole, attracting people to rural life. The business problems of development of ecological tourism as an independent tourism industry cannot and should not be addressed to without strategic analysis and forecasting varied (including negative consequences of tourist activity for society, culture and environment as well as without and without the development and implementation of forms of ecological tourism aimed at harmonizing nature and culture of nature management by the population.

Interactions between recreational drugs and antiretroviral agents.
Antoniou, Tony; Tseng, Alice Lin-In
2002-10-01
To summarize existing data regarding potential interactions between recreational drugs and drugs commonly used in the management of HIV-positive patients. Information was obtained via a MEDLINE search (1966-August 2002) using the MeSH headings human immunodeficiency virus, drug interactions, cytochrome P450, medication names commonly prescribed for the management of HIV and related opportunistic infections, and names of commonly used recreational drugs. Abstracts of national and international conferences, review articles, textbooks, and references of all articles were also reviewed. Literature on pharmacokinetic interactions was considered for inclusion. Pertinent information was selected and summarized for discussion. In the absence of specific data, prediction of potential clinically significant interactions was based on pharmacokinetic and pharmacodynamic properties. All protease inhibitors (PIs) and nonnucleoside reverse transcriptase inhibitors are substrates and potent inhibitors or inducers of the cytochrome P450 system. Many classes of recreational drugs, including benzodiazepines, amphetamines, and opioids, are also metabolized by the liver and can potentially interact with antiretrovirals. Controlled interaction studies are often not available, but clinically significant interactions have been observed in a number of case reports. Overdoses secondary to interactions between the "rave" drugs methylenedioxymethamphetamine (MDMA) or gamma-hydroxybutyrate (GHB) and PIs have been reported. PIs, particularly ritonavir, may also inhibit metabolism of amphetamines, ketamine, lysergic acid diethylmide (LSD), and phencyclidine (PCP). Case series and pharmacokinetic studies suggest that nevirapine and efavirenz induce methadone metabolism, which may lead to symptoms of opiate withdrawal. A similar interaction may exist between methadone and the PIs ritonavir and nelfinavir, although the data are less consistent. Opiate metabolism can be inhibited or induced by

With the current expansion of data linkage research, the challenge is to find the balance between preserving the privacy of person-level data whilst making these data accessible for use to their full potential. We describe a privacy-protecting safe haven and secure remote access system, referred to as the Secure Anonymised Information Linkage (SAIL) Gateway. The Gateway provides data users with a familiar Windows interface and their usual toolsets to access approved anonymously-linked datasets for research and evaluation. We outline the principles and operating model of the Gateway, the features provided to users within the secure environment, and how we are approaching the challenges of making data safely accessible to increasing numbers of research users. The Gateway represents a powerful analytical environment and has been designed to be scalable and adaptable to meet the needs of the rapidly growing data linkage community. PMID:24440148

Is Montenegro Considered as a Sports-Recreational Destination?
Directory of Open Access Journals (Sweden)
Sanja Pekovic
2018-06-01
Full Text Available The paper aims to examine if, according to the tourists coming to the country, Montenegro is considered as a sport-recreational destination. The data used in the study is extracted from the Montenegrin survey called Guest Survey 2014, comprising of 35 questions related to the tourist travel behavior and satisfaction during their stay in Montenegro. The paper uses the results of the study to provide descriptive statistics concerning the motives of tourist to visit Montenegro (one of the question is related to sport-recreational activities. Furthermore, it verifi es link between tourists’ motivation related to sport -recreational activities to come to Montenegro and their overall satisfaction with sport -recreational activities. The results indicated that only around 1% of tourists in our sample who visited Montenegro indicated sport- recreational activities as the main motive for the visit, around 3% of tourists indicated sport- recreational activities as a second motive while around 5% of tourists indicated sport and recreational activities as the third motive. However, around 60% of tourists reported that they were satisfi ed with overall sport -recreational activities during their stay in Montenegro. This study shows that even that Montenegrin sport-recreational off er is on the satisfactory level, managers and policy-makers should provide additional eff ort to present Montenegro as a sport-recreational destination since very low percentage of tourists are motivated to visit Montenegro related to these activities. The paper thus concludes by setting recommendations related to diversifi cation of Montenegrin tourism off er by pursuing sports-recreational tourism forms.

Historical shifts are occurring in marijuana policy. The effect of legalizing marijuana for recreational use on rates of adolescent marijuana use is a topic of considerable debate. To examine the association between the legalization of recreational marijuana use in Washington and Colorado in 2012 and the subsequent perceived harmfulness and use of marijuana by adolescents. We used data of 253 902 students in eighth, 10th, and 12th grades from 2010 to 2015 from Monitoring the Future, a national, annual, cross-sectional survey of students in secondary schools in the contiguous United States. Difference-in-difference estimates compared changes in perceived harmfulness of marijuana use and in past-month marijuana use in Washington and Colorado prior to recreational marijuana legalization (2010-2012) with postlegalization (2013-2015) vs the contemporaneous trends in other states that did not legalize recreational marijuana use in this period. Perceived harmfulness of marijuana use (great or moderate risk to health from smoking marijuana occasionally) and marijuana use (past 30 days). Of the 253 902 participants, 120 590 of 245 065(49.2%) were male, and the mean (SD) age was 15.6 (1.7) years. In Washington, perceived harmfulness declined 14.2% and 16.1% among eighth and 10th graders, respectively, while marijuana use increased 2.0% and 4.1% from 2010-2012 to 2013-2015. In contrast, among states that did not legalize recreational marijuana use, perceived harmfulness decreased by 4.9% and 7.2% among eighth and 10th graders, respectively, and marijuana use decreased by 1.3% and 0.9% over the same period. Difference-in-difference estimates comparing Washington vs states that did not legalize recreational drug use indicated that these differences were significant for perceived harmfulness (eighth graders: % [SD], -9.3 [3.5]; P = .01; 10th graders: % [SD], -9.0 [3.8]; P = .02) and marijuana use (eighth graders: % [SD], 5.0 [1.9]; P = .03; 10th graders

Recreational uses of unsurfaced trails inevitably result in their degradation, with the type and extent of resource impact influenced by factors such as soil texture, topography, climate, trail design and maintenance, and type and amount of use. Of particular concern, the loss of soil through erosion is generally considered a significant and irreversible form of trail impact. This research investigated the influence of several use-related, environmental, and managerial factors on soil loss on recreational trails and roads at Big South Fork National River and Recreation Area, a unit of the U.S. National Park Service. Regression modeling revealed that trail position, trail slope alignment angle, grade, water drainage, and type of use are significant determinants of soil loss. The introduction of individual and groups of variables into a series of regression models provides improved understanding and insights regarding the relative influence of these variables, informing the selection of more effective trail management actions. Study results suggest that trail erosion can be minimized by avoiding “fall-line” alignments, steep grades, and valley-bottom alignments near streams, installing and maintaining adequate densities of tread drainage features, applying gravel to harden treads, and reducing horse and all-terrain vehicle use or restricting them to more resistant routes.This research also sought to develop a more efficient Variable Cross-Sectional Area method for assessing soil loss on trails. This method permitted incorporation of CSA measures in a representative sampling scheme applied to a large (24%) sample of the park's 526 km trail system. The variety of soil loss measures derived from the Variable CSA method, including extrapolated trail-wide soil loss estimates, permit an objective quantification of soil erosion on recreational trails and roads.

Full Text Available The article is a contribution to the centennial celebration of the Faculty of Theology at the University of Pretoria. It forms part of the section in the programme titled ‘Ethos – Critical perspectives on our past and a gateway to our future’ and is dedicated to Yolanda Dreyer who was the first female professor appointed in the Faculty of Theology of the University of Pretoria. The article reflects on aspects of the present-day populist discourse in South Africa and globally, which is enhanced by neonationalistic separatism. The following issues are critically discussed: homophobia regarding sexual minorities, a lack of sensitivity for the negative effects of male domination and the objection to English as the lingua franca for teaching. These aspects are assessed against the background of the Derridean notion of ‘deconstruction’ and the contributions of the first professors employed in the Faculty of Theology since its inception in 2017.

A gateway for phylogenetic analysis powered by grid computing featuring GARLI 2.0.
Bazinet, Adam L; Zwickl, Derrick J; Cummings, Michael P
2014-09-01
We introduce molecularevolution.org, a publicly available gateway for high-throughput, maximum-likelihood phylogenetic analysis powered by grid computing. The gateway features a garli 2.0 web service that enables a user to quickly and easily submit thousands of maximum likelihood tree searches or bootstrap searches that are executed in parallel on distributed computing resources. The garli web service allows one to easily specify partitioned substitution models using a graphical interface, and it performs sophisticated post-processing of phylogenetic results. Although the garli web service has been used by the research community for over three years, here we formally announce the availability of the service, describe its capabilities, highlight new features and recent improvements, and provide details about how the grid system efficiently delivers high-quality phylogenetic results. © The Author(s) 2014.

Social class culture cycles: how three gateway contexts shape selves and fuel inequality.
Stephens, Nicole M; Markus, Hazel Rose; Phillips, L Taylor
2014-01-01
America's unprecedented levels of inequality have far-reaching negative consequences for society as a whole. Although differential access to resources contributes to inequality, the current review illuminates how ongoing participation in different social class contexts also gives rise to culture-specific selves and patterns of thinking, feeling, and acting. We integrate a growing body of interdisciplinary research to reveal how social class culture cycles operate over the course of the lifespan and through critical gateway contexts, including homes, schools, and workplaces. We first document how each of these contexts socializes social class cultural differences. Then, we demonstrate how these gateway institutions, which could provide access to upward social mobility, are structured according to middle-class ways of being a self and thus can fuel and perpetuate inequality. We conclude with a discussion of intervention opportunities that can reduce inequality by taking into account the contextual responsiveness of the self.

Physical-recreational activities and persons with disability
Directory of Open Access Journals (Sweden)
Potić Srećko
2014-01-01
Full Text Available Recreational activities represent individual or organized group activities chosen by free will, which help individuals to maintain good health, physical and working condition. In addition to the required physical segment, recreation also includes mental component which refers to strengthening of the will and determination, acquisition and development of self-control. With physical and mental aspect of recreational activities, many authors especially emphasize the importance of socio-psychological component of recreation. The aim of this paper is to review the so far published scientific and professional works in which the problem of recreational activities of persons with cerebral palsy, sight impairment, intellectual disability and autism is discussed, by studying the available literature. During the research we used the electronic data base of Serbian Library Consortium for Coordinated Acquisition, Google Scholar, as well as published material available in print. The participation of persons with disabilities in physical-recreational activities in the community is determined by the individual characteristics of the person, but with the community factors as well. The results of many studies show that persons with disabilities participate less in leisure and physical recreational activities and that is largely related to the level of social integration of these persons. Taking into account the fact that the participation of persons with disabilities in physical-recreational activities largely correlates with the quality of life of these persons, it is necessary to increase the number of recreational services that the community offers, as well as to specialise, modify and adapt some of them in relation to the needs of these persons. Also, it is recommended that as an integral part of all therapeutic approaches to persons with disability, the training of these persons for the appropriate use of their leisure time be included.

Gateways: Expanding knowledge through broader participation
Directory of Open Access Journals (Sweden)
Phil Nyden
2008-09-01
Full Text Available This new journal, Gateways: International Journal of Community Research and Engagement, responds to a growing global movement of university-collaborative research initiatives. It also strives to fill a gap created by the sparse number of journals which publish outcomes of community-engaged research and work concerning community engagement. We seek articles based on research that is the result of actively engaged research-practitioner collaborative projects, has the potential of informing community-based activities or develops understanding of community engagement. Combining different knowledge bases that have traditionally been separated into academic and non-academic worlds can dramatically increase information flowing to scholars, community leaders and activists seeking to improve the quality of life in local communities around the world. We also wish to encourage work that contributes to the scholarship of engagement.

Full Text Available The study examines the core meaning of intrinsic shopping to understand their experimental aspects of recreational and leisure shopping. The study focus only on female shoppers of age group ranging from 25-30, and understand their mall experiences because this segment is newly transform into self dependent segment which have less social and familial liabilities and have enough enthusiasm to explore the world or their boundaries. The Grounded theory use for identification of recreational shopping themes which are (a seeking experiences and (b experimental shopping and each have respective sub themes. The themes are connected to the key idea that shoppers are motivated by their expectations and desires. The study uses social constructivism to find and understand the shopper meanings in real terms rather than imposing and judgment on them. The findings described the way people do recreational shopping and how shopping malls use as leisure space and become facilitators of recreational shopping activities. Females use malls to fulfill their recreational and leisure shopping experiences as this is the great way of enjoying shopping for females of small towns. In malls females not only enjoy product experiences but services experiences also which makes their shopping interesting. The way the female of this age category use malls help the marketers and retailers to understand this segment shopping patterns.

One of the basic assumptions of the travel cost method for recreational demand analysis is that the travel cost is always incurred for a single purpose recreational trip. Several studies have skirted around the issue with simplifying assumptions and dropping observations considered as nonconventional holiday-makers or as nontraditional visitors from the sample. The effect of such simplifications on the benefit estimates remains conjectural. Given the remoteness of notable recreational parks, multi-destination or multi-purpose trips are not uncommon. This article examines the consequences of allocating travel costs to a recreational site when some trips were taken for purposes other than recreation and/or included visits to other recreational sites. Using a multi-purpose weighting approach on data from Gros Morne National Park, Canada, we conclude that a proper correction for multi-destination or multi-purpose trip is more of what is needed to avoid potential biases in the estimated effects of the price (travel-cost) variable and of the income variable in the trip generation equation.

We compared breeding activity of Ambystoma maculatum (Spotted Salamander) and Rana sylvatica (Wood Frog) in artificial impoundments to patterns in natural wetlands over a three-year period in the Delaware Water Gap National Recreation Area. Rana sylvatica were 5.6 times more likely to use natural bodies of water for breeding than artificial impoundments, while A. maculatum were 2.7 times more likely to use natural bodies of water. Both species were approximately 9 times more likely to breed in fishless bodies of water than in waters with predatory fish. Ambystoma maculatum were 6 times more likely to breed in wetlands with more stable seasonal hydroperiods, while R. sylvatica were only 2 times more likely to do so. We conclude that the high likelihood of fish presence in impoundments was the primary explanation for why both species were less likely to use impoundments than natural wetlands, while the tendency of A. maculatum to avoid natural wetlands with shorter hydroperiods explained why differences in use between pond types was more pronounced for R. sylvatica.

The BUG BITBUS Universal Gateway
International Nuclear Information System (INIS)
Nawrocki, G.
1996-01-01
The BITBUS Universal Gateway (BUG) provides a unique, cost effective solution to many different computer interface problems. Each BUG node, utilizing ''on board'' intelligence, has the ability to provide a communication link between BITBUS protocol and other computer-signal interfaces. Among them, IEEE-488, RS232, and raw analog and binary signal 1/0. BITBUS is a multidrop, multinode link with the ability to communicate over great distances. By using this method of signal transfer, along with the communication conversion ability of the BUG, one could accomplish such things as the ability to run IEEE-488 instruments over great distances, extend a multidrop links to RS232 instruments, and provide a convenient interface point for remote analog and binary 1/0 signals, all on one homogeneous network. The BUG not only provides this through the wired ''twisted pair'' standard of BITBUS, but extends the ability to fiber optic communications for signal transfer over extreme distances and through electrically ''noisy'' environments

Using social media to quantify nature-based tourism and recreation.
Wood, Spencer A; Guerry, Anne D; Silver, Jessica M; Lacayo, Martin
2013-10-17
Scientists have traditionally studied recreation in nature by conducting surveys at entrances to major attractions such as national parks. This method is expensive and provides limited spatial and temporal coverage. A new source of information is available from online social media websites such as flickr. Here, we test whether this source of "big data" can be used to approximate visitation rates. We use the locations of photographs in flickr to estimate visitation rates at 836 recreational sites around the world, and use information from the profiles of the photographers to derive travelers' origins. We compare these estimates to empirical data at each site and conclude that the crowd-sourced information can indeed serve as a reliable proxy for empirical visitation rates. This new approach offers opportunities to understand which elements of nature attract people to locations around the globe, and whether changes in ecosystems will alter visitation rates.

Energy Technology Data Exchange (ETDEWEB)
Benson, P.; Codina, R.; Cornwall, B.
1978-09-01
The guidelines laid out for the five subjects investigated in this series are to take a holistic view of energy conservation policies by describing the overall system in which they are implemented; provide analytical tools and sufficiently disaggregated data bases that can be adapted to answer a variety of questions by the users; identify and discuss some of the important issues behind successful energy conservation policy; and develop an energy conservation policy in depth. This report contains the design of a specific policy that addresses energy conservation in recreational travel. The policy is denoted as an ''Information System for the National Park Service.'' This work is based on prior examination of the characteristics of the recreational trip and decision making for the recreational experience. The examination revealed which aspects of the recreational travel system needed to be addressed to encourage energy-efficient modal decisions for recreational travel. This policy is briefly described in Section 1, the ''Summary of Initiative.'' A more detailed discussion of the policy follows. The material which led to the policy's formation is developed in Section 2: Importance and Impact of the Recreational Trip; Weekend Travel; The Flowchart: Decision Making for the Recreational Experience; Policy Development for Phase 1 ''Planning the Trip;'' and Objectives and Strategies for ''Planning the Trip.''

The development of minimally invasive techniques allowed access to the necrotic cavity through transperitoneal, retroperitoneal, transmural and transpapillary routes. The choice of access to walled-off pancreatic necrosis (WOPN) should depend not only on the spread of necrosis, but also on the experience of the clinical center. Herein we describe treatment of a patient with multilocular symptomatic walled-off pancreatic necrosis using minimally invasive techniques. The single transmural access (single transluminal gateway technique - SGT) to the necrotic collection of the patient was ineffective. The second gastrocystostomy was performed using the same minimally invasive technique as an extra way of access to the necrosis (multiple transluminal gateway technique - MTGT). In the described case the performance of the new technique consisting in endoscopic multiplexing transmural access (MTGT) was effective enough and led to complete recovery of the patient.

CernVM Online and Cloud Gateway: a uniform interface for CernVM contextualization and deployment
International Nuclear Information System (INIS)
Lestaris, G; Charalampidis, I; Berzano, D; Blomer, J; Buncic, P; Ganis, G; Meusel, R
2014-01-01
In a virtualized environment, contextualization is the process of configuring a VM instance for the needs of various deployment use cases. Contextualization in CernVM can be done by passing a handwritten context to the user data field of cloud APIs, when running CernVM on the cloud, or by using CernVM web interface when running the VM locally. CernVM Online is a publicly accessible web interface that unifies these two procedures. A user is able to define, store and share CernVM contexts using CernVM Online and then apply them either in a cloud by using CernVM Cloud Gateway or on a local VM with the single-step pairing mechanism. CernVM Cloud Gateway is a distributed system that provides a single interface to use multiple and different clouds (by location or type, private or public). Cloud gateway has been so far integrated with OpenNebula, CloudStack and EC2 tools interfaces. A user, with access to a number of clouds, can run CernVM cloud agents that will communicate with these clouds using their interfaces, and then use one single interface to deploy and scale CernVM clusters. CernVM clusters are defined in CernVM Online and consist of a set of CernVM instances that are contextualized and can communicate with each other.

Earthquake Data Enhanced Cyber-Infrastructure for Disaster Evaluation and Response (E-DECIDER) is a NASA-funded project developing capabilities for decision-making utilizing remote sensing data and modeling software in order to provide decision support for earthquake disaster management and response. E-DECIDER incorporates earthquake forecasting methodology and geophysical modeling tools developed through NASA's QuakeSim project in order to produce standards-compliant map data products to aid in decision-making following an earthquake. Remote sensing and geodetic data, in conjunction with modeling and forecasting tools, help provide both long-term planning information for disaster management decision makers as well as short-term information following earthquake events (i.e. identifying areas where the greatest deformation and damage has occurred and emergency services may need to be focused). E-DECIDER utilizes a service-based GIS model for its cyber-infrastructure in order to produce standards-compliant products for different user types with multiple service protocols (such as KML, WMS, WFS, and WCS). The goal is to make complex GIS processing and domain-specific analysis tools more accessible to general users through software services as well as provide system sustainability through infrastructure services. The system comprises several components, which include: a GeoServer for thematic mapping and data distribution, a geospatial database for storage and spatial analysis, web service APIs, including simple-to-use REST APIs for complex GIS functionalities, and geoprocessing tools including python scripts to produce standards-compliant data products. These are then served to the E-DECIDER decision support gateway (http://e-decider.org), the E-DECIDER mobile interface, and to the Department of Homeland Security decision support middleware UICDS (Unified Incident Command and Decision Support). The E-DECIDER decision support gateway features a web interface that

The role of human outdoor recreation in shaping patterns of grizzly bear-black bear co-occurrence.
Directory of Open Access Journals (Sweden)
Andrew Ladle
Full Text Available Species' distributions are influenced by a combination of landscape variables and biotic interactions with other species, including people. Grizzly bears and black bears are sympatric, competing omnivores that also share habitats with human recreationists. By adapting models for multi-species occupancy analysis, we analyzed trail camera data from 192 trail camera locations in and around Jasper National Park, Canada to estimate grizzly bear and black bear occurrence and intensity of trail use. We documented (a occurrence of grizzly bears and black bears relative to habitat variables (b occurrence and intensity of use relative to competing bear species and motorised and non-motorised recreational activity, and (c temporal overlap in activity patterns among the two bear species and recreationists. Grizzly bears were spatially separated from black bears, selecting higher elevations and locations farther from roads. Both species co-occurred with motorised and non-motorised recreation, however, grizzly bears reduced their intensity of use of sites with motorised recreation present. Black bears showed higher temporal activity overlap with recreational activity than grizzly bears, however differences in bear daily activity patterns between sites with and without motorised and non-motorised recreation were not significant. Reduced intensity of use by grizzly bears of sites where motorised recreation was present is a concern given off-road recreation is becoming increasingly popular in North America, and can negatively influence grizzly bear recovery by reducing foraging opportunities near or on trails. Camera traps and multi-species occurrence models offer non-invasive methods for identifying how habitat use by animals changes relative to sympatric species, including humans. These conclusions emphasise the need for integrated land-use planning, access management, and grizzly bear conservation efforts to consider the implications of continued access for

Springs in Black Canyon of the Colorado River, directly south of Hoover Dam in the Lake Mead National Recreation Area, Nevada and Arizona, are important hydrologic features that support a unique riparian ecosystem including habitat for endangered species. Rapid population growth in areas near and surrounding Black Canyon has caused concern among resource managers that such growth could affect the discharge from these springs. The U.S. Geological Survey studied the springs in Black Canyon between January 2008, and May 2014. The purposes of this study were to provide a baseline of discharge and hydrochemical data from selected springs in Black Canyon and to better understand the sources of water to the springs.

The study is a geohydrologic reconnaissance of about 170 square miles in the Lake Mead National Recreation Area from Las Vegas Wash to Opal Mountain, Nevada. The study is one of a series that describes the geohydrology of the recreation area and that indentifies areas where water supplies can be developed. Precipitation in this arid area is about 5 inches per year. Streamflow is seasonal and extremely variable except for that in the Colorado River, which adjoins the area. Pan evaporation is more than 20 times greater than precipitation; therefore, regional ground-water supplies are meager except near the Colorado River, Lake Mead, and Lake Mohave. Large ground-water supplies can be developed near the river and lakes, and much smaller supplies may be obtained in a few favorable locations farther from the river and lakes. Ground water in most of the areas probably contains more than 1,000 milligrams per liter of dissolved solids, but water that contains less than 1,000 milligrams per liter of dissolved solids can be obtained within about 1 mile of the lakes. Crystalline rocks of metamorphic, intrusive and volcanic origin crop out in the area. These rocks are overlain by conglomerate and mudstone of the Muddy Creek Formation, gravel and conglomerate of the older alluvium, and sand and gravel of the Chemehuevi Formation and younger alluvium. The crystalline rocks, where sufficiently fractured, yield water to springs and would yield small amounts of water to favorably located wells. The poorly cemented and more permeable beds of the older alluvium, Chemehuevi Formation, and younger alluvium are the better potential aquifers, particularly along the Colorado River and Lakes Mead and Mohave. Thermal springs in the gorge of the Colorado River south of Hoover Dam discharge at least 2,580 acre-feet per year of water from the volcanic rocks and metamorphic and plutonic rocks. The discharge is much greater than could be infiltrated in the drainage basin above the springs

Different forms of outdoor recreation have different spatiotemporal activity patterns that may have interactive or cumulative effects on wildlife through human disturbance, physical habitat change, or both. In western North America, shrub-steppe habitats near urban areas are popular sites for motorized recreation and nonmotorized recreation and can provide important habitat for protected species, including golden eagles. Our objective was to determine whether recreation use (i.e., number of recreationists) or recreation features (e.g., trails or campsites) predicted golden eagle territory occupancy, egg-laying, or the probability a breeding attempt resulted in ≥1 offspring (nest survival). We monitored egg-laying, hatching and fledging success, eagle behavior, and recreation activity within 23 eagle territories near Boise, Idaho, USA. Territories with more off-road vehicle (ORV) use were less likely to be occupied than territories with less ORV use (β = -1.6, 85% CI: -2.8 to -0.8). At occupied territories, early season pedestrian use (β = -1.6, 85% CI: -3.8 to -0.2) and other nonmotorized use (β = -3.6, 85% CI: -10.7 to -0.3) reduced the probability of egg-laying. At territories where eagles laid eggs, short, interval-specific peaks in ORV use were associated with decreased nest survival (β = -0.5, 85% CI: -0.8 to -0.2). Pedestrians, who often arrived near eagle nests via motorized vehicles, were associated with reduced nest attendance (β = -11.9, 85% CI: -19.2 to -4.5), an important predictor of nest survival. Multiple forms of recreation may have cumulative effects on local populations by reducing occupancy at otherwise suitable territories, decreasing breeding attempts, and causing nesting failure. Seasonal no-stopping zones for motorized vehicles may be an alternative to trail closures for managing disturbance. This study demonstrates the importance of considering human disturbance across different parts of the annual cycle, particularly where

Pacific Gateway: State Surveillance and Interdiction of Criminal Activity on Vancouver’s Waterfront
Directory of Open Access Journals (Sweden)
Chris Madsen
2018-03-01
Full Text Available Unionised work environments within large seaports attract transnational organised crime, and this presents a challenge for law enforcement agencies. If media stories are true, a motorcycle club called the Hells Angels has established a presence on Vancouver area waterfronts since coming to the province of British Columbia. Associations between longshore union locals, club members, and known contacts are implied and presented as evidence of participation in criminality. This paper revisits the perception that criminal activity is endemic in the Port of Vancouver because of a lack of policing, adequate resources, and indifference from port authorities, employer bodies, as well as union leadership. In an era of heightened concerns about public safety and national security, federal and provincial governments understand the importance of seaports, especially in Vancouver and up the Fraser River. These port facilities are important to international trade that flows through them as part of Asia-Pacific Gateway and Corridor initiatives. Therefore, targeted investments, close coordination amongst government departments and agencies, and engagement with waterfront stakeholders promote secure places hard for organised criminals to operate freely.

A virtue analysis of recreational marijuana use
Sullivan, Ezra; Austriaco, Nicanor
2016-01-01
Several empirical studies suggest that recreational marijuana is popularly perceived as an essentially harmless rite of passage that ends as young people settle into their careers and their adult intimate relationships. Is this perception accurate? To answer this question, we evaluate the morality of recreational marijuana use from a virtue perspective guided by the theological synthesis of St. Thomas Aquinas. Since the medical data reveals that recreational marijuana use is detrimental to th...

Full Text Available The aim of the paper is to widen knowledge about motivation of elite, recreational athletes and non-athletes. Participants from the elite athletes group (n = 35, 16.7 ± .70 years old were football players of the Slovak national team. Recreational athletes (n = 31, 16.8 ± .80 years old and non-athletes (n = 29, 15.7 ± .60 years old are visiting Grammar School in Zvolen. D-M-V standardized questionnaire was used to determine performance motivation. The Kolmogorov-Smirnov's test disconfirmed the null hypothesis on the normality of data. We used the non-parametric Kruskal-Wallis and Mann-Whitney U tests to determine the statistical significance of the differences. The results showed that there were significant (p .0.01 differences with large effect size (η2 ≥ .14 in all the three (the performance motives scale, the anxiety inhibiting performance scale and the anxiety supporting performance scale dimensions among the research groups. The motivation of elite athletes is significantly higher (p = .048; r = .25 compared to the recreational athletes. Also, compared to the non-athletes, the level of performance motivation is significantly higher (p = .002; r = .51 in the elite athletes. Based on the results of the study we can formulate the statement that the level of performance motivation is contingent on the level of sport activity.

In the last two decades, coral reefs have become popular among recreational divers, especially inside marine protected areas. However, the impact caused by divers on benthic organisms may be contributing to the degradation of coral reefs. We analyzed the behavior of 142 scuba divers in the Abrolhos National Marine Park, Brazil. We tested the effect of diver profile, reef type, use of additional equipment, timing, and group size on diver behavior and their contacts with benthic organisms. Eighty-eight percent of divers contacted benthic organism at least once, with an average of eight touches and one damage per dive. No significant differences in contacts were verified among gender, group size, or experience level. Artificial reef received a higher rate of contact than pinnacle and fringe reefs. Specialist photographers and sidemount users had the highest rates, while non-users of additional equipment and mini camera users had the lowest contact rates. The majority of contacts were incidental and the highest rates occurred in the beginning of a dive. Our findings highlight the need of management actions, such as the provision of pre-dive briefing including ecological aspects of corals and beginning dives over sand bottoms or places with low coral abundance. Gathering data on diver behavior provides managers with information that can be used for tourism management.

Full Text Available Often, youth in the foster care system have traumatic experiences associated with abuse and separation from their biological family. These experiences may lead to emotional, psychological, and behavioral problems that challenge the new adoptive family dynamic. This article introduces the Respite and Recreation (R & R program in a Midwestern area. R & R combines faculty, staff, and graduate students from a local University, local community resources, and staff from a local adoption agency to provide recreation, respite, and professional support services for children with special needs and their adoptive parents. The R & R program provides the adopted children with structured recreation programs for their growth, the parents with a break from stress, and volunteer students with opportunities to incorporate their academic learning into real life situations. Service learning programs such as the R & R also provide university faculty with excellent opportunities to conduct action research.

Full Text Available The starting point of this article follows a premise that demographic characteristics of a population, which constructs and consumes space on a daily basis, and cultural landscapes are interconnected, i.e. that certain demographics can be read from urban cultural landscapes in a greater or lesser extent. Of all the demographic structures incorporated in Croatian urban landscapes it is easiest to recognize the age, educational, religious, economic and ethnic/national composition, while the racial and gender structures are almost unnoticed. This paper presents the results of the analysis of the relationship between the population age structure and recreational landscapes of the eastern outskirts of Zagreb – Dubrava. By using the statistical analysis in the first part of the article, the author discusses the past and current age composition, as well as the trend of population aging. After that, the author provides descriptive and/or statistical analysis of some elements of recreational landscape in Dubrava, such as green areas, children’s and sports playgrounds, public gardens, sports centers, Grad mladih, and second homes, in order to determine the contemporary situation in the landscape. Considering the dominant process of rapid aging of the Dubrava population, a mismatch between the needs for recreation of the aged population and the real situation in the space was noticed. The lack of recreational facilities is evident not only for those intended for elderly residents, but also for the younger ones; the reasons are usually associated with the lack of financial resources, and in some cases with decision-making processes on a higher level than those of the city districts. Two subtypes of recreational landscapes were differentiated: sports and recreational landscape and second home landscape.

This study investigated risk and protective factors for recreational and hard drug use in Malaysian adolescents and young adults. Participants (n = 859; M age = 17.24 years, SD = 2.75 years, range = 13-25 years; 59% male) were recruited from secondary schools, technical colleges, a juvenile detention center and a national training center in Malaysia. A version of the Communities That Care survey validated for use in Malaysia (Razali & Kliewer, 2015) was used to assess study constructs. One in 6 adolescents and 1 in 3 young adults reported lifetime recreational and hard drug use, with greater use reported by males across all drug categories. Structural equation modeling was used to determine the strongest risk and protective factors for recreational and hard drug use. The overall pattern of findings was similar for recreational and hard drug use. Shared risk factors for lifetime recreational and hard drug use included early initiation of antisocial behavior, peer antisocial behavior, and peer reinforcement for engaging in antisocial behavior; shared protective factors included religious practices and opportunities for prosocial school involvement. Multiple group analyses comparing adolescents and young adults indicated that patterns of risk and protective factors predicting drug use differed across these age groups. There were fewer significant predictors of either recreational or hard drug use for young adults relative to adolescents. Results suggest that interventions should target multiple microsystems (e.g., peer groups, family systems, school environments) and be tailored to the developmental stage of the individual.

HAPS Gateway Link in the 5850-7075 MHz and Coexistence with Fixed Satellite Service
Directory of Open Access Journals (Sweden)
M. Ahmed
2013-09-01
Full Text Available Gateway link is essential to connect HAPS platform to terrestrial based networks. This crucial link is incorporated in HAPS fixed service spectrum allocation in considerably high frequencies, renders the link for more attenuations by atmospheric gases, and rain effects, especially when the regional climate is not favorable. However, under the agenda item 1.20 of World Radio Conference-2012 (WRC-12 new HAPS allocation in the 5850-7075 MHz band is proposed. Although, spectrum features are incomparably reliable, on the contrary, Fixed Satellite Service (FSS uplink transmissions will have signal levels much higher than those in HAPS systems and have the potential for causing interference at the HAPS gateway receiver. In this article a key aspect of co-channel interference phenomena is investigated to facilitate optimum frequency sharing in the band in question. By proposing mitigation techniques and statistical method this generic prediction model enhances the capability of the HAPS spectrum sharing and provides flexibility in spectrum planning for different fixed services.

A PICKSC Science Gateway for enabling the common plasma physicist to run kinetic software
Hu, Q.; Winjum, B. J.; Zonca, A.; Youn, C.; Tsung, F. S.; Mori, W. B.
2017-10-01
Computer simulations offer tremendous opportunities for studying plasmas, ranging from simulations for students that illuminate fundamental educational concepts to research-level simulations that advance scientific knowledge. Nevertheless, there is a significant hurdle to using simulation tools. Users must navigate codes and software libraries, determine how to wrangle output into meaningful plots, and oftentimes confront a significant cyberinfrastructure with powerful computational resources. Science gateways offer a Web-based environment to run simulations without needing to learn or manage the underlying software and computing cyberinfrastructure. We discuss our progress on creating a Science Gateway for the Particle-in-Cell and Kinetic Simulation Software Center that enables users to easily run and analyze kinetic simulations with our software. We envision that this technology could benefit a wide range of plasma physicists, both in the use of our simulation tools as well as in its adaptation for running other plasma simulation software. Supported by NSF under Grant ACI-1339893 and by the UCLA Institute for Digital Research and Education.

Full Text Available According to the importance of environmental resources in preserving natural ecosystems and human life, preserving these resources and preventing their destruction is necessary. National Park of Urmia Lake in West Azarbayjan province of Iran is the settlement of rare species for different animals and herbs. Every year a lot of internal and foreign passengers and tourists visit this national Park, so the purpose of this study is recreation demand function derivation in National Park of Urmia Lake and determining social and economic factors on demand function. So we used travel cost pattern within the frame work of family production function. Optimal sample volume was 75 tourists and data is related to 2010 summer. Results showed recreation demand function has positive relation with tourists income, quality of National Park and visitor`s education, also it has negative relation with recreation shadow price that is according to theoretical expectations. So, quality improvement of National Park as an effective key factor on recreation demand and using suitable pricing policy are recommended.

Battelle Energy Alliance, LLC, managing and operating contractor for the U.S. Department of Energy's Idaho National Laboratory, is the lead laboratory for U.S. Department of Energy Advanced Vehicle Testing. Battelle Energy Alliance, LLC contracted with Intertek Testing Services, North America (ITSNA) to collect data on federal fleet operations as part of the Advanced Vehicle Testing Activity's Federal Fleet Vehicle Data Logging and Characterization study. The Advanced Vehicle Testing Activity study seeks to collect data to validate the utilization of advanced electric drive vehicle transportation. This report focuses on the Golden Gate National Recreation Area (GGNRA) fleet to identify daily operational characteristics of select vehicles and report findings on vehicle and mission characterizations to support the successful introduction of plug-in electric vehicles (PEVs) into the agencies' fleets. Individual observations of these selected vehicles provide the basis for recommendations related to electric vehicle adoption and whether a battery electric vehicle or plug-in hybrid electric vehicle (PHEV) (collectively PEVs) can fulfill the mission requirements. GGNRA identified 182 vehicles in its fleet, which are under the management of the U.S. General Services Administration. Fleet vehicle mission categories are defined in Section 4, and while the GGNRA vehicles conduct many different missions, only two (i.e., support and law enforcement missions) were selected by agency management to be part of this fleet evaluation. The selected vehicles included sedans, trucks, and sport-utility vehicles. This report will show that battery electric vehicles and/or PHEVs are capable of performing the required missions and providing an alternative vehicle for support vehicles and PHEVs provide the same for law enforcement, because each has a sufficient range for individual trips and time is available each day for charging to accommodate multiple trips per day.

2016-06-01
Full Text Available Abuja Master Plan provided development of adequate Green Areas and other Recreational Facilities within the Federal Capital City (FCC, as part of its sustainability principles and provided for these recreational facilities within each neighborhood (FCDA, 1979. However, there have been several recent foul cries about the negative development of recreational facilities and the abuse of the Master Plan in the FCC. The motivation for carrying out this study arose from the observation that recreational facilities in Phase 1 of the Federal Capital City Abuja are not clearly developed as intended by the policy makers and thus, the need to identify the recreational facilities in the Phase 1 of FCC and observe their level of development as well as usage. The field survey revealed that the Central Business District and Gazupe have higher numbers of recreational facilities with 45 and 56. While Wuse II (A08 and Wuse II (A07 Districts have lesser recreational facilities with 10 and 17. The field survey further revealed that all the districts in Phase 1 have over 35% cases of land use changes from recreational facilities to other use. The survey shows that over 65% of these recreational facilities are fully developed. The study also shows that just about 11% of the recreational sporting facilities were developed in line with the Abuja Master Plan in Phase 1. The study revealed that recreational facilities in Phase 1 of the FCC, Abuja has not being developed in compliance with the Abuja Master Plan.

This article studies how accounting for the benefits of recreational fisheries affects the formation and stability of an international fisheries agreement (IFA) on the management of Baltic salmon stocks. The interaction between four countries is modelled through a partition function game, under two...... scenarios. In the first scenario, countries take their participation decision for the IFA based only on the net present value of profits from commercial fisheries. In the second scenario, the net present value of the recreational benefits from angling is also considered. The results show that accounting...... for recreational benefits leads to the formation of the grand coalition, whereas only partial cooperation occurs when payoffs are confined to profits from commercial fisheries....

Recreational impacts on the fauna of Australian coastal marine ecosystems.
Hardiman, Nigel; Burgin, Shelley
2010-11-01
This paper reviews recent research into the ecological impacts of recreation and tourism on coastal marine fauna in Australia. Despite the high and growing importance of water-based recreation to the Australian economy, and the known fragility of many Australian ecosystems, there has been relatively limited research into the effects of marine tourism and recreation, infrastructure and activities, on aquatic resources. In this paper we have reviewed the ecological impacts on fauna that are caused by outdoor recreation (including tourism) in Australian coastal marine ecosystems. We predict that the single most potentially severe impact of recreation may be the introduction and/or dispersal of non-indigenous species of marine organisms by recreational vessels. Such introductions, together with other impacts due to human activities have the potential to increasingly degrade recreation destinations. In response, governments have introduced a wide range of legislative tools (e.g., impact assessment, protected area reservation) to manage the recreational industry. It would appear, however, that these instruments are not always appropriately applied. Copyright 2010 Elsevier Ltd. All rights reserved.

CHARACTERISTICS OF SPORTS RECREATIONAL TOURISM IN MONTENEGRO
Directory of Open Access Journals (Sweden)
Ognjen Jovović
2010-03-01
Full Text Available Basic for realization of tourist movements lays in meeting cultural and recreational needs of potential customers. If we know that largest number of tourists represents part of recreational ones, than is not hard to realize how large potential lays in that number of potential guests. On this fact should be built strategy of movement of tourist offer of Montenegro for it extreme potentials on which can be founded concrete project. In this work are given basic assumptions for development of sport recreational shapes of tourism with stress to natural potentials that directly determine shape of sport recreational activities that represent basis of tourist offer. Offer should be created in that way that it is adapted to wide segment of recreational guests and not professional sportsmen, although they also should not be underestimated but one should know that in order to create conditions for arrival of sports professionals offer has to be completely different and more specialized that requires creating of conditions of existence of highly developed sports infrastructure, while for amateurs a lot can be done in “system of improvising”, satisfying basic criteria – recreation in conditions of untouched and well preserved nature with securing maximal level of security and protection of guests, in order to prevent possible unwilling consequences that can lead to injury of guests and for development and realization of such project one need a much less funds than is building of facilities that should meet standards of professional sportsmen. The aim is to create good offer at good infrastructure, logistics and with good equipment with securing maximal security, adaptation to various wishes of guests, taking in consideration their structure is conditioned by age, health condition, physical fitness as personal wishes toward sports and recreational activities.

Periurban forests shifting from recreation to wellness
Directory of Open Access Journals (Sweden)
Pascal Papillon
2012-02-01
Full Text Available In France and in Europe, periurban forests are subject to high social demands for recreational purposes. These demands take the form of frequent visits for sports or rest. Local governments have succeeded in creating new wooded parks close to cities that are highly appreciated by the population. A survey was run on visitors to forests around three mid-sized cities, addressing what they do in the forests and why. The answers revealed differences between suburban parks and larger national forests located farther from the cities. New approaches targeting health may also be observed on the part of both individuals and the health sector. These new approaches indicate the existence of a wellness function in periurban forests.

Accessibility: global gateway to health literacy.
Perlow, Ellen
2010-01-01
Health literacy, cited as essential to achieving Healthy People 2010's goals to "increase quality and years of healthy life" and to "eliminate health disparities," is defined by Healthy People as "the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions." Accessibility, by definition, the aforementioned "capacity to obtain," thus is health literacy's primary prerequisite. Accessibility's designation as the global gateway to health literacy is predicated also on life's realities: global aging and climate change, war and terrorism, and life-extending medical and technological advances. People with diverse access needs are health professionals' raison d'être. However, accessibility, consummately cross-cultural and universal, is virtually absent as a topic of health promotion and practice research and scholarly discussion of health literacy and equity. A call to action to place accessibility in its rightful premier position on the profession's agenda is issued.

Service interoperability through advanced media gateways
van der Meer, S
2000-01-01
The convergence of telecommunications systems and the Internet causes a variety of concepts for service integration. The focus of the recent research studies and the work of several standardization bodies lies mostly on the interworking of services and the universal service access from end-user systems including both fixed and wireless terminals. All approaches are driven by the concept of providing several technologies to users by keeping the peculiarity of each service alive. But, developments should not only concentrate on media adaptation between VoIP and PSTN, but also consider the adaptation among completely different types of applications as for example E- mail, facsimile, or voice. Unified messaging, which is an already accepted service on the market, provides solutions for conversions of different application protocols into each other. The functionality of converting one medium into another is implemented here in so-called media gateways. This paper provides an overview of the current developments in...

Assessing the value of recreational divers for censusing elasmobranchs.
Directory of Open Access Journals (Sweden)
Christine A Ward-Paige
Full Text Available BACKGROUND: Around the world, researchers are using the observations and experiences of citizens to describe patterns in animal populations. This data is often collected via ongoing sampling or by synthesizing past experiences. Since elasmobranchs are relatively rare, obtaining data for broad-scale trend analysis requires high sampling effort. Elasmobranchs are also relatively large and conspicuous and therefore it may be possible to enlist recreational divers to collect data on their occurrence and relative abundance from daily dive activities. For this, however, a good understanding of the value of data collected by recreational divers is essential. METHODOLOGY/PRINCIPAL FINDINGS: Here, we explore the value of recreational divers for censusing elasmobranchs using a diverse set of data sources. First, we use a simulation experiment to explore detection rates of the roving diver technique, used by recreational divers, across a range of fish densities and speeds. Next, using a field survey, we show that inexperienced recreational divers detect and count elasmobranchs as well as experienced recreational divers. Finally, we use semi-structured interviews of recreational dive instructors to demonstrate the value of their recollections in terms of effort and their descriptions of spatial and temporal distributions of sharks in Thailand. CONCLUSIONS/SIGNIFICANCE: Overall, this study provides initial ground-work for using recreational divers for monitoring elasmobranch populations. If used appropriately, citizen-collected data may provide additional information that can be used to complement more standardized surveys and to describe population trends across a range of spatial and temporal scales. Due to the non-extractive nature of this data, recreational divers may also provide important insight into the success of conservation initiatives, such as shark sanctuaries and no-take zones.

Basin of the river Oskil as a tourist-recreational area
Directory of Open Access Journals (Sweden)
Валентина Клименко
2017-09-01
Full Text Available At the current stage of Ukraine’s economic development tourism is a priority sector of our country’s economy. Due to the fact that Ukraine has set a high priority goal - to join the European Union, we should pay attention to the conditions of various areas and sectors of our economy, in particular, the quality of tourism services, whether the recreational sector meets European standards. Many economically developed countries make tourism the most important among other sectors to fill the budget and closely monitor the quality of tourist services. Due to the rapid development of the tourism industry in our country the question has arisen as to conformity of recreational facilities conditions with international standards and finding new places of recreation, including water tourism. The aim of the study is to highlight the Oskil River Basin (within Kharkiv region as a tourist and recreational area and the use of the study materials in the learning process. The article deals with problems of insufficiently studied use of the river Oskil basin both as a tourist, and a recreational area. The hydrographic characteristics of the reservoir have been studied to illustrate the conformity of water objects with the standards and requirements of tourist and recreational activities; methods and techniques of water resources assessment have been analyzed for recreation; the river Oskil (within Ukraine and Chervono-Oskil reservoir have been assessed on the possibility of tourist-recreational use. The ways to use the study materials in education have been determined. Recreational potential of the river and the reservoir should not be underestimated. Thus, analyzing resources of the Oskil river basin and Chervono-Oskil reservoir in terms of recreation, we can conclude that the water of the river is not equally suitable for recreational purposes. The river basin can be used as an object of beach-bathing leisure, tourist boating and rafting, sport rafting

The MIM web gateway to IP multicast e-meetings
Parviainen, Roland; Parnes, Peter
2003-12-01
As video conferencing and e-meeting systems are used more and more on the Internet and in businesses it becomes increasingly important to be able to participate from any computer at any location. Often this is impossible, since these systems requires often special software that are not available everywhere or impossible to install for administrative reasons. Many locations also lack the necessary network infrastructure such as IP multicast. This paper presents a WWW gateway system that enables users to participate using only a standard web browser. The design and architecture of the system are described and performance tests that show the scalability of the system are also presented.

Knowledge and awareness of heat-related morbidity among adult recreational endurance athletes
Shendell, Derek G.; Alexander, Melannie S.; Lorentzson, Lauren; McCarty, Frances A.
2010-07-01
Adults have been increasingly motivated to compete in recreational endurance sports events. Amateurs may lack a complete understanding of recommended strategies for handling heat and humidity, making heat-related illnesses increasingly possible. This is compounded by global climate change and increasing average surface and air temperatures, especially in urban areas of industrialized nations in Europe and North America that have hosted most events to date. We conducted an on-line, secure survey at the 2nd Annual ING Georgia Marathon and Half-Marathon in Atlanta, Georgia, in 2008. We included previously validated questions on participant socio-demographics, training locations, and knowledge and awareness of heat-related illnesses. Participants were aware of heat illnesses, and of heat stroke as a serious form of heat stress. However, the majority, across age and gender, did not understand the potential severity of heat stroke. Furthermore, 1-in-5 participants did not understand the concept of heat stress as a form of heat-related illness, and how heat stress may result from buildup of muscle-generated heat in the body. Adult recreational endurance athletes are another susceptible, vulnerable population sub-group for applied research and public health educational interventions, especially in urban areas of industrialized nations in Europe and North America.

A contingent valuation study was conducted with adult Kenyan citizens and foreign tourists to estimate the value of recreational benefits arising from coral reefs at Mombasa Marine National Park and Reserve (MMNPR), and to assess the implications for local reef management. Citizen and foreign visitors to MMNPR were willing to pay an extra 2.2 (median = 1.6) and 8 (median = 6.7) per visit respectively, in addition to current park entrance fees, to support reef quality improvements. By aggregating visitors’ willingness to pay bids over the number of visitors to MMNPR in 2006-2007 the value of benefits was estimated at 346,733, which was more than twice the total annual operational expenditure of 152,383 for MMNPR. The findings indicate that annual revenues from citizen and foreign visitors may be increased by 60% to 261,932 through the implementation of proposed higher park fees of 3.10 for citizens and 15 for foreign visitors. However, any fee increase would serve to intensify concerns among citizens that only relatively affluent Kenyans can afford to visit MMNPR. Park managers need to demonstrate that the extra revenue would be used to fund the proposed conservation activities. This valuation study demonstrates that visitors are prepared to pay higher user fees for access to the marine protected area revealing considerable untapped resource to finance reef quality improvements.

Liability concerns and shared use of school recreational facilities in underserved communities.
Spengler, John O; Connaughton, Daniel P; Maddock, Jason E
2011-10-01
In underserved communities, schools can provide the physical structure and facilities for informal and formal recreation as well as after-school, weekend, and summer programming. The importance of community access to schools is acknowledged by authoritative groups; however, fear of liability is believed to be a key barrier to community access. The purpose of this study was to investigate perceptions of liability risk and associated issues among school administrators in underserved communities. A national survey of school administrators in underserved communities (n=360, response rate of 21%) was conducted in 2009 and analyzed in 2010. Liability perceptions in the context of community access were assessed through descriptive statistics. The majority of respondents (82.2%) indicated concern for liability should someone be injured on school property after hours while participating in a recreational activity. Among those that did not allow community access, 91% were somewhat to very concerned about liability and 86% believed that stronger legislation was needed to better protect schools from liability for after-hours recreational use. Among those who claimed familiarity with a state law that offered them limited liability protection, nearly three fourths were nevertheless concerned about liability. Liability concerns are prevalent among this group of school administrators, particularly if they had been involved in prior litigation, and even if they indicated they were aware of laws that provide liability protection where use occurs after hours. Reducing these concerns will be important if schools are to become locations for recreational programs that promote physical activity outside of regular school hours.

Full Text Available Recreation fulfils two functions in terms of labour economics: (1 as a commodity, it participates in the formation of national wealth by creating jobs, and (2 through its purpose, it boosts the workforce “re-creation” in all economic sectors by having a major contribution to people’s recovery, therefore reducing the psychosocial risks and creating premises for improvement of labour productivity. The present paper focuses on the first topic regarding the labour economics of recreation, namely the workforce operating within the sector and puts into comparative perspective two European Union member states: France and Romania. While in France the enterprises specialised in providing artistic, cultural, sports, entertainment or gambling and betting activities form a well-established and efficient economic sector, in Romania they make for an emerging and fast growing industry. Results will show that the local recreation sectors in the two countries have rather different development orientations at macroeconomic level - while in France the tendency seems to be increasing the number of workers per business, Romania rather shows an orientation towards creating numerous scattered micro businesses. With respect to employment, the local recreation sector reveals to be highly unusual in terms of working hours, heterogeneity and variety of professions, and lack of formalised job offer. However, these abnormalities are overridden by the superior intrinsic working conditions and the prolonged work sustainability.

Historically, many of the most important mathematical concepts arose from problems that were recreational in origin. This book takes advantage of that fact, using recreational mathematics - problems, puzzles and games - to teach students how to think critically. Encouraging active participation rather than just observation, the book focuses less on mathematical results than on how these results can be applied to thinking about problems and solving them. Each chapter contains a diverse array of problems in such areas as logic, number and graph theory, two-player games of strategy, solitaire ga

Full Text Available This paper describes a novel methodology for generating models of demand for informal outdoor recreation. We analyze visitor data from multiple forest sites across Great Britain. We introduce a wide range of variables typically omitted from most economic demand models of recreation. These include on-site characteristics, and off-site locational drivers of visitation including substitute and complement availability. A Poisson multilevel model is used to model visitor counts, and the methodology is applied to a dataset of more than 10,000 visits to open-access woodland sites. Results confirm it identifies a broader range of demand drivers than previously observed. The use of nationally available explanatory variables enhances the transferability and hence general applicability of the methodology.

The Gateway Paper--financing health in Pakistan and its linkage with health reforms.
Nishtar, Sania
2006-12-01
Pakistan currently principally uses three modes of financing health--taxation, out of pocket payments and donor contributions of which the latter is the least significant in terms of size. Less than 3.6% of the employees are covered under the social security scheme and there is a limited social protection mechanism, which collectively serves the health needs of 3.4% of the population. The main issues in health financing include low spending, lack of attention to alternate sources of financing and issues with fund mobilization and utilization.
