L2 written corrective feedback has been investigated from different perspectives in SLA research (e.g. Ahmadian & Tajabadi, 2015; Bitchener & Knoch, 2010; Ferris, 2006). Taking the cognitive and sociocultural paradigms into account, the aims of the current study are twofold: Firstly, it attempts to find if corrective feedback is effective in improving the linguistic accuracy of L2 learners' tense/aspect use in writing. Secondly, it tries to measure which feedback type (direct, indirect, and negotiated) has a more significant effect on the mentioned linguistic structures. Seventy-five pre-intermediate university EFL learners were selected and asked to participate in the study; they were randomly divided into direct, indirect, negotiated feedback groups, and a control group. During six-week sessions of providing feedback on tenses/aspects, the participants were required to write diary journals on their academic life. The direct and indirect groups received feedback on their diaries, having 10 minutes time in the class to observe the feedback. The negotiated feedback group received 10 minutes one-to-one contingent feedback on the errors. After comparing the four groups, the results showed that all the treatment groups did outperform the control group which indicated that feedback was effective. Moreover, the findings showed no significant difference among the feedback types. This implies that teachers can provide any of the feedback types for learners so far as tense/aspect errors are concerned in their writing.

Sustainability accounting by presenting a holistic view of the organization activities and providing a balanced view of its economic, social and environmental impacts and benefits, and by presenting sustainability reporting seeks to encourage business units and investors to maintain the mutual benefits of all stakeholders in the society. Given the criticisms that researchers have had about the efficiency of sustainability reporting, the purpose of this article is to develop sustainability accounting by presenting a new model that can address the challenges in sustainability accounting and can be a good alternative to sustainability reporting. Social value-added is the sum of tangible and intangible values created and added to society by a business through technological development/change and the knowledge of its manufacturing engineers and managers. In this research, to test the proposed social value added model, Nano engine oil was selected randomly and the test was performed using paired comparison of data. The results of the research showed that social value-added statement can be an appropriate report for evaluating the economic, social and environmental performance of a business entity. Nano engine oil has a social value added of 3797.2 percent compared to regular engine oil, that 15 percent of it is related to tangible value added and 85 percent to intangible value added. 

This study investigated the impact of interaction and output modality on vocabulary learning and retention of EFL learners. To investigate the impact of Interaction, solitary (n =69) and collaborative (n =62) groups served as experimental and No Interaction No Output (n =26) as control group. To address the effect of modality, spoken (n =39) and written (n =31) modalities served as experimental and No output modality (n =26) as control group. The study was done in 8 weeks. The groups read passages with target words highlighted. Solitary and collaborative groups reconstructed the passages individually or in dyads. The spoken and written modality groups reconstructed them in the respective modality. Then, pretest, immediate, and delayed posttests were administered. The ANOVA results showed that the collaborative group outperformed the other groups and spoken modality outperformed the written modality group focusing on interaction and modality separately. The 2×2×2 ANOVA results showed significant main effects for time, interaction, and output modality. An ‘interaction’ effect was found between time and interaction, time and modality, and modality and Interaction. The ‘interaction’ between time, Interaction, and modality was insignificant. The findings have implications for language teachers, syllabus designers, and language testing experts.
