Navigating websites is often a frustrating process: Website visitors, despite their widely varying and individual information-seeking needs, must contend with static, general-purpose link structures that have been set in place by website owners. Because many visitors tend to browse for the same content, they are individually repeating the same navigation activity. Visitors would benefit from be...

In this paper, we describe a field study with a tour guide robot that guided visitors through a historical site. Our focus was to determine how a robot’s orientation behaviour influenced visitors’ orientation and the formations groups of visitors formed around the robot. During the study a remotecontrolled robot gave short guided tours and explained some points of interest in the hall of Festiv...

BACKGROUND In addition to livestock movements, other between-farm contacts such as visitors may contribute to the spread of contagious animal diseases. Knowledge about such contacts is essential for contingency planning. Preventive measures, risk-based surveillance and contact tracing may be facilitated if the frequency and type of between-farm contacts can be assessed for different types of fa...

Transmission of organisms within the hospital setting has become a topic of major concern not only for patients and healthcare facilities but also for government agencies and the general public. This increased awareness has occurred in part due to the spread of organisms that have limited treatment options, such as carbapenem-resistant Enterobacteriaceae (CRE), as well as the heightened recogni...

In object-oriented programming the visitor design pattern allows for the addition of new operations on a data hierarchy, but lends itself to scattered traversal code and makes visitors difficult to combine. Previous attempts to solve these issues have separated traversal code from the data structure but still face a lack of modularity in visitor computation making it difficult– if not impossibl...

BACKGROUND Rio de Janeiro in Brazil will host the Summer Olympic Games in 2016. About 400,000 non-immune foreign tourists are expected to attend the games. As Brazil is the country with the highest number of dengue cases worldwide, concern about the risk of dengue for travelers is justified. METHODS A mathematical model to calculate the risk of developing dengue for foreign tourists attending...

INTRODUCTION Workplace violence against nurses is a serious problem. Nurses from a US urban/community hospital system employing more than 5,000 nurses researched the incidence of workplace violence against nurses perpetrated by patients or visitors in their hospital system. METHODS Survey research and retrospective database review methods were used. Nurse participants (all system-employed nur...

The objectives of this study are to determine the visitors’ willingness to pay for conservation of the resources at Gunung Gede Pangrango National Park (TNGP), and to determine the satisfaction of visitors towards the use of the ecotourism resources of the park. The dichotomous choice Contingent Valuation Method (CVM) was employed to determine the willingness to pay (WTP). A total of 423 respon...

the protection and use of recreational areas as a sustainable resource can be a very significant issues, especially when they are located within a protected areas. different management approaches such as limits of acceptable changes (lac) can be performed to provide the balance between the use and the protection of resources. lac method is one of the planning frameworks that are used in tourism...
