Riemann problems for the compressible Euler system in two space dimensions are complicated and difficult, but a viable alternative remains missing. We list merits of one-dimensional Riemann problems and compare them with those for the current two-dimensional Riemann problems, to illustrate their worthiness. We approach twodimensional Riemann problems via the methodology promoted by Andy Majda i...

The purpose of this study was to examine the relationship of job satisfaction to job difficulty and worthiness, reported by the clinical psychologists who worked at medical institutions. A mail survey of 748 clinical psychologists working at hospital and clinics revealed the following results. First, job satisfaction was related more to job situation than job content. Also, job satisfaction was...

BACKGROUND Mental health patients describe "being understood" as an experience that evokes feelings of importance, worthiness, and empowerment. However, the experience of "being misunderstood" is more prevalent in patients' relationships with health care providers. Negative consequences such as vulnerability, dehumanization, and frustration reveal that being misunderstood has the potential to d...

Bystander intervention is a potentially potent tool in the primary prevention of sexual assault but more information is needed to guide prevention programs (Banyard 2008). Undergraduates (378 women and 210 men, primarily White) at a central coast California university completed an anonymous questionnaire measuring five barriers identified by the situational model of bystander intervention (Lata...

This paper aims to analyze how virtual teams deal with the process of trust among the people who are part of it. The research is characterized as descriptive. The survey data techniques that were used were questionnaires via Internet and interviews by telephone. The participants of this research were eight managers from Embratel, a telecommunication company in Brazil. The results of this resear...

There is great enthusiasm about the potential of computers for enhancing student learning in science and engineering. The Structural Engineering Department at the University of California, San Diego (UCSD) has initiated the Webshaker Pilot Project with the goal of facilitating accessibility to live, on-demand, experimental testing earthquake engineering applications. The project is presented in...

The logistics of knowledge means managing the need for knowledge, as well as the supply and transfer of knowledge. The transfer of knowledge occurs between generations, in a regional innovation system and today, with increasing frequency and importance, across international borders. A company`s balance sheet of knowledge gives important arguments in support of material property, which is import...

The major challenge faced by wireless sensor networks is security. Because of dynamic and collaborative nature of sensor networks the connected sensor devices makes the network unusable. To solve this issue, a trust model is required to find malicious, selfish and compromised insiders by evaluating trust worthiness sensors from the network. It supports the decision making processes in wireless ...

Peer-to-peer networks have become increasingly popular in the recent years. In an open peer-to-peer network peers often have to interact with unknown peers and need to manage the risk in their communications. It is very important for peers to select a trustworthy peer to accomplish a task. Peers must be able to determine the trustworthiness of other peers to increasing uncertainty and risk. Thu...
