Drawing on Robinson’s cognition hypothesis, the study attempted to examine how task conditions influence EFL learners’ oral performance and whether learners’ individual differences in terms of tolerance of ambiguity and self-efficacy mediate the effects of such conditions. To this end, 62 Iranian intermediate EFL learners from private language institutes in Tehran performed four dyadic decision...

The WHO recommends integrating interventions to address the devastating TB/HIV co-epidemics in South Africa, yet integration has been poorly implemented and TB/HIV control efforts need strengthening. Identifying infected individuals is particularly difficult in rural settings. We used mathematical modeling to predict the impact of community-based, integrated TB/HIV case finding and additional c...

abstractthe current study examined the modification devices (mds) used by non-native speakers (nnss) learning efl during dyadic task-based interactions. three meaning-oriented tasks, namely picture-description, spot-the-difference, and opinion-exchange, were used to elicit data from 24(12 male and 12 female, forming 4 male-male, 4 female-female, and 4 male-female dyads) iranian efl learners wit...

background: tuberculosis (tb) spread pattern is influenced by geographic and social factors. nowadays geographic information system (gis) is one of the most important epidemiological instrumentation identifying high-risk population groups and geographic areas of tb. the aim of this study was to determine the correlation between climate and geographic distribution of tb in khuzestan province usi...

tuberculosis (tb) is one of the 10 leading cause of deaths in developing countries. understanding the cause and risk factors of tb death and lowering them can reduce its mortality rate. the aim of this study was to assess the cause and risk factors for death of tuberculosis. a retrospective descriptive study was conducted in khuzestan province in the south west of iran, from 2002 to 2006. medic...

Business applications composed of heterogeneous distributed components or Web services need mediation to resolve data and process mismatches at runtime. This paper describes mediation in IRS-III, a framework and platform for developing WSMO-based Semantic Web Services. We present our approach to mediation within Semantic Web Services and highlight the role of WSMO mediator types when solving mi...

This paper contributes to the techniques for conceptual representation of data analysis algorithms and data integration facilities as well as processes to specify data and behavior semantics in one paradigm. An investigation of a novel approach for applying a combination of semantically different platform-independent rule-based languages (dialects) for interoperable conceptual specifications ov...

Estimating the mechanisms that connect explanatory variables with the explained variable, also known as “mediation analysis,” is central to a variety of social science fields, especially psychology, and increasingly fields like epidemiology. Recent work on the statistical methodology behind mediation analysis points to limitations in earlier methods. We implement in Stata computational approach...
