WWW service has enabled development of e-learning systems that are considered to be direct application of the information and communication technology. xTEx-Sys system is an Web-based authoring shell with adapted environment to each actor of the system. Formal representation of course material in xTEx-Sys involves ontology driven knowledge description. Student’s knowledge evaluation in xTEx-Sys...

The study aims at investigating the influence of English as a Foreign Language (EFL) students' perfectionism and anxiety on their Willingness to Communicate (WTC) in EFL classes. To do so, a set of questionnaires, namely “Willingness To Communicate” (MacIntyre, et al., 2001), “Foreign Language Classroom Anxiety” (Horwitz, et al., 1986)  and “Multidimensional Perfectionism Scales” (Hewitt & Flet...

Actor programs consist of a number of concurrent objects called actors, which communicate by exchanging messages. Nondeterminism in actors results from the different possible orders in which available messages are processed. Systematic testing of actor programs explores various feasible message processing schedules. Dynamic partial-order reduction (DPOR) techniques speed up systematic testing b...

The present work solves two-dimensional Advection-Dispersion Equation (ADE) in a semi-infinite domain. A variable source concentration is regarded as the monotonic decreasing function at the source boundary (x=0). Depth-dependent variables are considered to incorporate real life situations in this modeling study, with zero flux condition assumed to occur at the exit boundary of the domain, i.e....

social norms are rules and expectations by which a society guides the behavior of its members based on the process of social control, the level of political legitimacy and procedural justice practices in the areas of governance, social order is guaranteed. in this study, the independent variables associated with three domains of social control, procedural justice and social capital to norm comp...

The release of dangerous contaminants to the atmosphere due to human activities is an extensively discussed issue (Oelkers & Cole 2008). The economic development often underestimated the consequences of a massive release of substances into the environment. Politic tried to introduce some regulation but in the case of CO2 emissions, the introduction of the “Carbon Tax” and the other attempts wer...

This research was designed to assess the effects of a manipulation of observers' focus of attention--from a focus on the actor to a focus on the actor's situation--upon observers' attributions of attitude to an actor in a simulation of a forced-compliance cognitive dissonance experiment. Observers induced through empathy instructions to focus attention on the actor's situation inferred less act...
