Circulation of scientific discoveries occurs in various discourse communities. Adopting an audience-oriented view of writing (Hyland, 2010) and drawing on the appraisal theory (Martin & White, 2005), the current study aimed to explore the evaluative strategies psychologists would use to share their specialist knowledge with scholarly and non-scholarly readers. To this end, a corpus of 38 academic research articles and 38 popularized science articles from the archive of an English international refereed journal, Current Psychology , and two English popularized magazines, Newsweek and New Scientist , were analyzed in terms of attitude resources of appraisal, namely appreciation, affect, and judgment . The results of the study revealed that palpable degrees of persuasion were achieved through including certain attitude elements in both corpora despite no statistically significant difference. The results debunked the myth of objectivity in academic discourse and disclosed the psychology experts’ appealing to persuasive tools for convincing the specialist and non-specialists of the truth value of their research outcomes. The findings carry pedagogical implications for English for the students of psychology courses. Indeed, future psychologists need to get familiar with the common discursive strategies to address their intended audience in academic and non-academic settings.

This study aimed to investigate the effect of task-based language teaching on news-story writing in Iranian EFL context. To this end, a quasi-experimental, pre- and post-evaluation research design was employed. First, 78 Iranian BA sophomores majoring in translation at Islamic Azad University, Hamedan Branch, were selected through convenient sampling as the participants of the study. They were then randomly divided into two treatment and control groups--task-based group (TB) and conventional teaching group (TC) respectively. Both groups were initially given a test on news story writing to measure their writing ability at the pre-treatment stage. Then, the control group was taught through explanations abstracted from some deductive plans and reading-oriented method of teaching news story structure. The other group was exposed to a six-weak TB treatment based on Willis’ TBL framework. The post-treatment researcher-made test was then administered to compare the participants’ writing progress. The obtained statistical results showed that the employment of the task-based language learning scenario does not lead to an overall significant improvement of Iranian EFL learners’ performance in news-story writing as compared with the conventional teaching of the same skill. This is perhaps due to learners’ negative attitude towards TBLT, which originates from the inconsistency of TBLT with the educational philosophy in Iran. Therefore, TBLT programs may need to be modified on the basis of the local and traditional specifications of the education in the target community to be able to develop the learners’ news-story writing skill.             

The main idea of IoT is to connect several objects to each other through Internet. In the field of Computer Network the main problem identified by researchers is network congestion. Now a day’s network congestion is increasing very rapidly because IoT connect a huge number of devices to internet. A transport layer protocol TCP (Transmission Control Protocol) is accountable for network congestion control. The behavior of TCP is not stable as it takes long time to fill the available capacity of the network. It also continuously keeps assessing the capacity of data transmission through increasing the limits.TCP drops its data transmission rate aggressively when packets are dropped, which significantly reduces the throughput. This paper suggests a new approach, stable transmission control protocol for IoT applications. The experimental results show that stable transmission control protocol achieves better performance in terms of goodput.
