One of the controversial issues in learning English is the appropriate use of formulaic sequences as one of the effective factors in pragmatic production. Not merely the language proficiency level, but also the individual’s capability to adapt to a new culture plays a significant role in the appropriate use of formulaic sequences. First, this study intends to find the relationship between cultural intelligence and the use of formulaic sequences. Second, it seeks to identify whether there is a significant difference between the second language learners with different proficiency levels in the appropriate use of formulaic sequences. From the Universiti Sains Malaysia, a total of 50 Malaysian students participated in the study. First, the participants completed an oral Discourse Completion Task (DCT) test, and then they were required to fill a Cultural Intelligence Scale (CQS). The statistical analysis revealed a significant correlation between the level of proficiency and the production of formulaic sequences. However, no relationship was found between the level of cultural intelligence and the production of formulaic sequences among the participants. The results obtained from this research would benefit the curriculum designers by boosting the communication skills of ESL learners. However, more studies should be conducted with different instruments and methodology to ensure more accurate results.

Purpose-based costing is a modern evaluation technique used to advance organizations and companies. However, Iran has not utilized the technique yet. Thus, the present study aims to investigate factors affecting costing systems based on purpose in Hospitals of Tabriz in northwestern Iran. The statistical population of the study included all staff members working in the financial section of Hospitals in Tabriz from among which 64 subjects responding to the questionnaires were selected as statistical sample. The questionnaires were of two parts. In the first part, effective factors including organizational, human and environmental factors were investigated. In the second part, barriers of operating the costing system including technical, behavioral and cultural barriers were identified. This study is a survey type in which non-parametric T test was used to assess research hypotheses. Results from the study revealed that organizational, human and environmental factors affect successful implementation of purpose-based costing system and technical, behavioral and cultural barriers do not affect its implementation.
