Performance in Collaborative Activity: Contribution of Intersubjectivity Theory

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

Analyzing Learners’ Collaborative Behaviors Using Activity Theory

The primary goal of the study is to analyze learner behaviors during collaborative group work in a digital learning community. A qualitative data analysis program, NVivo 2, was used to code the vast amount of online transcripts and written interviews based on the grounded theory. Resulting codes were aligned in the four subsystems of activity theory and the activation of subsystems by group wor...

Usable Collaborative Email Requirements Using Activity Theory

Email is the most common collaborative tool in use today. Although originally designed as an asynchronous communication tool, it is being used increasingly for information management, coordination and collaboration tasks. For effective collaborative work, email must be designed that meets users’ needs and their experience. The traditional approach to designing interfaces has been increasingly c...
