Penetration of smartphones and increasing use of social media on always-on devices has attracted the attention of enterprises and organizations to benefit from such platforms for better understanding of customers’ needs and more effectively communicate with potential consumers. For this purpose, the present study investigates the impact of social media adoption and media needs on online purchasing behavior. This study has also examined the moderating role of media type, gender and age in the relationship between variables of social media adoption and online purchasing behavior. A total of 410 questionnaires were collected on social media such as Instagram, Telegram and WhatsApp. SEM technique using PLS used as the analytical method to empirically test the proposed hypotheses. Results show that the effects of tension dimension on online purchasing behavior is mediated by social media adoption. Moreover, the effects of social media adoption on online purchasing behavior are moderated by age and medium type based on Multi-Group Analysis. The IPMA matrix shows that social media adoption had the highest importance, but the lowest performance. This study is significant in terms of innovation due to the use of new indicators effective in the area of statistical analyses. The use of FIMIX, CTA, permutation test, MGA, and IPMA matrix analyses is part of it.

The present study aimed at investigating the effect of peer feedback (PF) on EFL learners’ writing performance and writing anxiety. To this end, two intact classes including 48 intermediate EFL learners were selected and assigned into two groups of experimental and control (24 learners in each). This study had a quasi-experimental design including pre-test, treatment, and post-test to assess the students’ overall writing performance before and after the PF sessions. For data collection, the researchers used pre-test, post-test, 7 writing topics, and Cheng’s (2004) Second Language Writing Anxiety Inventory (SLWAI). The results of paired sample t-test and Mann-Whitney U Test revealed that the experimental group outperformed the control group due to the implementation of PF. Moreover, the researchers conducted Cheng’s SLWAI questionnaire at the end of the study. The findings indicated that the anxiety level of the experimental group receiving PF decreased to a significant extent. The implications are discussed in terms of writing instructors’ use of PF into writing classes to make the environment safer and more comfortable for the language learners to flourish their ideas.

Le présent travail est une étude phonologique portant sur le point de vue de Pierre Léon quand il aborde la difficulté de la production des groupes consonantiques du français par les apprenants, en général, et les iraniens, en particulier, dans son livre Introduction à la phonétique corrective. La question posée tourne autour des difficultés les plus importantes engendrées lors de l’apprentissage du français langue étrangère. Toutes les langues ne présentent pas les mêmes caractéristiques ni les mêmes difficultés et les apprenants de langue maternelle différente et surtout éloignée, se servent d’une stratégie simplifiant la prononciation telle insertion d'une voyelle qualifiée de parasite en début du mot, au sein du groupe consonantique. Selon Léon, cette voyelle parasite serait proche d'un /a/ chez les apprenants iraniens. Nous avons vérifié cette hypothèse auprès de ces derniers à l’Université d’Ispahan, en comparant leurs habitudes linguistiques et la structure du système phonétique de farsi avec ce que propose Léon. Les résultats montrent que contrairement à ce qu’il dit, dû au phénomène d'harmonisation, cette voyelle n’est pas une /a/, mais pour des raisons phonologiques elle ressemblerait plutôt à une /e/. Dans certains cas, elle tend vers une /o/.

One of the important issues in EFL instruction is the idea of eliminating students’ linguistic errors through providing corrective feedback (CF). Accordingly, this study investigated the effect of various CF types (i.e., comprehensive, selective, and no feedback) on advanced EFL learners’ writing in different writing conditions (i.e., individual & collaborative). 132 EFL advanced learners aged from 14-20 were considered as the main participants. Learners were divided into 6 groups (i.e., three individual and three collaborative writing conditions). Furthermore, each writing condition included three groups with selective, comprehensive, and no correction orientations. Data collection tools and procedures encompassed an institutionalized Placement Test, pre-test, and post-test. The treatment that lasted for nine sessions was followed by a post-test. Data were submitted to a series of ANOVA tests with follow up pair-wise comparisons and independent-samples t-tests. Findings indicated that: (1) CF, especially selective one, was more effective in enhancing learners’ writing accuracy, and (2) members of the collaborative writing groups outperformed those in the individual ones in terms of their writing accuracy development. The theoretical and practical implications are discussed in relation to enhancing writing accuracy of the learners.

To date, controversy among scholars exists on whether or not teachers should react to EFL learners' written grammar errors. This study investigated the effect of three feedback types (i.e., selective, comprehensive, and the one recommended by Truscott (1999), that is, no correction) with regard to possible improvements in accuracy in the writings of a total of 66 elementary EFL learners. It, further, sought whether such an effect would last in the long run. During 11 weeks, selected global (e.g., past tense, countable/uncountable, and comparative adjectives) and all grammar errors in the written pieces of the subjects in two treatment groups ( n= 22 in each) were reacted through coded underlining. However, in line with Truscott, the only reaction participants in the third group ( n= 22) received were comments such as great, good, ok, etc.. Analysis of the written pieces in the immediate and delayed post tests  revealed that selective feedback had a significantly more positive influence on learners' accurate use of selected grammatical structures  both in the short and in the long run. The implications are discussed in terms of effective guidelines for teaching writing in EFL contexts.
