Transition intermediaries are actors that support socio-technical transition processes by bridging structural deficiencies in a transitioning domain. Previous research has identified what roles perform and how. However, while domains definition state of change, the dynamics have hardly been studied. Therefore, we explore mechanisms driving change transition-supportive intermediaries, kind condi...

Secure multicast communication is a significant requirement in emerging applications in adhoc environments like military or public emergency network applications. Membership dynamism is a major challenge in providing complete security in such networks. This paper proposes a efficient Group Based Multicast Hierarchy (GBMH) algorithm for secret multicast communication, in which source nodes used ...

In this paper, we present our approach to introduce dynamism support to simulation environments, which adopts a Discrete Event System Specification (DEVS)-based modeling and simulation approach and builds upon previous work on Simulation Modeling Architecture (SiMA), a DEVS-based simulation framework developed at TUBITAK UEKAE. In the relevant literature there are already proposed solutions to ...

Recent research finds that perceived risk is closely associated with race and gender. In surveys of the American public a subset of white males stand out for their uniformly low perceptions of environmental health risks, while most nonwhite and nonmale respondents reveal higher perceived risk. Such findings have been attributed to the advantageous position of white males in American social life...

The paper investigates the relationship between pro-social norms and its implications for improved environmental outcomes. This is an area, which has been neglected in the environmental economics literature. We provide empirical evidence to demonstrate a robust link between perceived environmental cooperation (reduced public littering) and increased voluntary environmental morale. For this purp...

This study undertook a critical examination of the relationship between perception of environmental harm and consumer willingness to pay for environmental handling fees (EHF). This analysis was supplemented by asking study participants to indicate under what circumstances (and for what materials) they believe a visible fee is appropriate. This study found that there is a statistically significa...

This paper has examined the phenomenon of convergence of per capita out put levels across the IC countries for the 1960-1998 periods. Three concepts of convergence, i.e., sigma beta and relative beta, have been used. The estimated beta values reveals only a very weak convergence (?=.0014) across IC for 1960-1998 period. But when a more homogeneous group of countries were selected, the results s...

Favorable perceptions of the built and social neighborhood environment may promote outdoor physical activity (PA). However, little is known about their independent and interactive effects on neighborhood-specific outdoor PA. We examined associations of perceived built and social neighborhood environment factors, and their interactions, with objectively-measured neighborhood outdoor moderate-to-...
