the educational system is designed for some students’ kind of minds (e.g., those with strengths in attention, memory, language, social skills), for others, it is a daily struggle. unfortunately, the academic setting rarely accounts for this variability. regardless, at some point in time (for whatever reason), almost all students “hit a wall” (or face a challenge) which can make them doubt wheth...

We introduce nonlinear scalar field models for open and openclosed strings with spacetime derivatives encoded in the operator valued Riemann zeta function. The corresponding two Lagrangians are derived in an adelic approach starting from the exact Lagrangians for effective fields of p-adic tachyon strings. As a result tachyons are absent in these models. These new strings we propose to call zet...

social system based on mutual trust among members continues to exist. social trust in modem era is more important than earlier periods. subject of current report is focused on the trust of iranian students in different aspects. main question in this investigation is about social-political trust of these students (based on trust in islamic republic of iran) at the past and present. this matter e...

after a relatively long period of centralization and with the beginning of decentralization experiences since 1970s, the periodical orientations and trends of governments towards both centralization and decentralization systems appeared. stemming generally from political and economic domains, decentralization entered curriculum and education system from these domains. problems such as deficienc...

background and purpose: social accountability, a concept which is in the focal attention more than ever, is to provide service in the field of medical sciences. we aimed to identify the educational challenges to train accountable graduates in the medical education system to meet social needs. methods: this study was conducted by qualitative content analysis using in-depth semi-structured interv...

In this paper we study the phenomenon of UV/IR mixing in noncommutative field theories from the point of view of world-sheet openclosed duality in string theory. New infrared divergences in noncommutative field theories arise as a result of integrating over high momentum modes in the loops. These are believed to come from integrating out additional bulk closed string modes. We analyse this issu...
