Planning a trip to a particular destination can be a time consuming and daunting task. There is a wide range of information sources available, each claiming to present the best deals and the most complete tourist information. This information as well as the current weather, budget constraints, time constraints, and personal preferences all need to be taken into account when planning the perfect...

A trip through a virtual world is a powerful metaphor and a natural way of interacting with a geographic information system (GIS). Virtual reality (VR) systems provide visual realism and real-time navigation and interaction for data in core, but fail to cope with very large amounts of data, and to provide the general functionality of information systems. We describe a prototype system that over...

There is a general consensus that to effect a more sustainable transport policy, there is a necessity to reduce car use (especially for short trips). Resistance to modal transfer from cars has been shown to be embedded in various psycho-social obstacles which are not readily teased out in orthodox econometric studies of travel demand. We report on an empirical study which fuses psychometric (co...

An intramuscular injection of epinephrine combined with an oral antihistamine is the treatment of choice for life-threatening anaphylactic reactions that occur in remote settings. Legal issues aside, the purpose of this brief article is to review the options available to outdoor programs who wish to carry epinephrine into the field. There are currently four options available; all have been used...

Transforming growth factor beta receptor II interacting protein 1 (TRIP-1), a predominantly intracellular protein is localized in the ECM of bone. TRIP-1 lacks a signal peptide, therefore, in this study, we provide evidence that intracellular TRIP-1 can be packaged and exported to the ECM via exosomes. Overexpression of TRIP-1 in MC3T3-E1 cells resulted in increased matrix mineralization during...

The main goal of this study was to obtain insight about the factors that influence students' ability to learn during a field trip, in order to improve the planning and execution of learning field trips. The study was conducted in the context of a 1-day geological field trip for high school students in Israel. Three domains were tested by observations and questionnaires: (1) the nature of the le...

The onset and degree of injury occurring in animals that develop hyperoxic acute lung injury (HALI) is dependent on age at exposure, suggesting that developmentally regulated pathways/factors must underlie initiation of the epithelial injury and subsequent repair. Type II TGFβ receptor interacting protein-1 (TRIP-1) is a negative regulator of TGFβ signaling, which we have previously shown is a ...

The process of selection, configuration and consumption of tourist information services is a complex task for the user. This is not least since existing tools most often focus on supporting either the preor post-trip phase or the on-trip phase itself by providing context-aware services. The goal of this thesis is to establish a framework that makes pre-trip services context-aware, thus reducing...
