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...

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....

The effect of partial slip and temperature dependent fluid properties on the MHD mixed convection flow from a heated, non-linearly stretching surface in the presence of radiation and non-uniform internal heat generation/absorption is investigated. The velocity of the stretching surface was assumed to vary according to power-law form. Thermal transport is analyzed for two types of non-isothermal...

‎In this paper‎, ‎a coherent system consisting of non-identical dependent active components and‎ ‎equipped with non-identical dependent standby components is considered‎. ‎The main object of this study is the random quantity‎ ‎which account the number of surviving standby components when the system‎ ‎is failed‎. ‎We represent the distribution function of the corresponding random variable in ter...

liquidity is the most important aspect of stock markets development. this research investigates the effect of share issue privatization (sip) on tehran stock exchange (tse) liquidity. regarding the three assessable measures in sip, three hypotheses based on the number of privatized firms, the volume and the value of the sold stocks were defined and tested. in this research, the tse liquidity is...

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...
