Purpose: The principal purpose of the present article is to analyze the technical mechanisms and the categorization procedure of thesaurus, ontology, and their types in storage and retrieval of digital and non-digital content. The types of knowledge organization systems (KOSs) which are addressed in this article are Roget’s thesaurus, thesauri, Micro, Macro and Meta thesaurus, ontologies, and lower, middle, or upper-level ontologies. The study attempts to demonstrate categorization the procedure through determining the position of KOSs in the context of data, information, and knowledge (DIK) by explaining their engineering mechanisms such as data, information, and knowledge engineering in content storage and retrieval, especially digital content. Method: The research method relies on documented and historical methodology. Findings: As ontologies have taken the highest position amidst KOSs in making digital resources available in a web based environment, it is suggested that Iran and other developing countries use the capacities and capabilities of ontologies, especially in the development of national ontologies, in order to construct their knowledge-based infrastructure and system to achieve high performance in digital content engineering and management.

The identification of the cognitive, affective, social and even physiological factors affecting second or foreign language learning routes and rate has for long been a challenging aspiration for second language researchers. However, a recent preoccupation of the researchers in this area has been the study of the combinatorial impacts of such factors on second or foreign language learning processes and products. As a partial undertaking in this regard, this study investigated the relations pattern among some psychological and cognitive variables and foreign language learning achievement rate. The studied factors were self-regulation, goal-orientation, tolerance of ambiguity, and autonomy on the one hand and English as Foreign Language (EFL) learners’ ultimate achievement on the other hand. To this end, 250 Iranian BA level EFL students majoring English literature or English translation were selected based on convenience sampling procedure. Next, having obtained the participants' informed consent to participate in the study, the researchers administered Trait Self-Regulation Questionnaire (TSRQ), Goal Orientation, Tolerance of Ambiguity, and Learner Autonomy scales to them. In addition, concerning their L2 achievement rate measure, their BA level general English courses' GPA was obtained from the education office of the related universities. The data were statistically analyzed and the hypothetical model of interrelations among the given variables was tested using Structural Equation Modeling procedures. The results indicated that goal orientation and self-regulation significantly predicted L2 achievement; however, tolerance of ambiguity and learner autonomy were not found as strong predictors of L2 achievement. On the other hand, while self-regulation strongly predicted goal orientation, it was not verified to be a strong predictor of tolerance of ambiguity. The results also showed that goal orientation could strongly predict learner autonomy. A ready-made implication of the findings might be that the combinatorial effects of the psychological variables on cognitive processes like second language learning is quite complicated and different from the effects of each individual variable.      

The outbreak of Coronavirus disease, 2019 (COVID-19), started in late 2019 and developed into a pandemic by March 2020 and has become a global problem. Following the global outbreak and coronavirus spreading around the world, the WHO reported a statement on January 11, 2020, announcing the new Coronavirus outbreak as the sixth significant public health emergency in the world. In the stressful situation caused by the coronavirus epidemic, many jokes and Humor about this disease were distributed on social networks. In these circumstances, the question arises: Why do some people continue to make jokes about it, despite the mass perception of the coronavirus epidemic? The present research method was qualitative and Strauss and Corbin's version of the grounded theory was used. Participants were included the Telegram Social Network Comic Channel “https://t.me/s/jokcom” Members, which had more than 2879 members and those on Instagram and Twitter members who liked the corona content to the jokes about the covid-19 pandemic inside Iran. Based on the result, we found the effects and consequences of corona jokes. There was several factors involved in shaping the phenomenon of covids jokes. Joke and Humor are like a double-edged sword; in some situation, can be both harmful and helpful.

Socio-cultural diversity is a comprehensive phenomenon across the world so that there are only a few monoethnical countries. Every country attempts to plan its policy to manage its ethnical diversity on one hand according to goals and approaches of its political system and on the other hand according to its specific ethnical diversity pattern. The Islamic Republic of Iran also is among countries with ethnical diversity and attempts to administrate its policy according to its political system approach toward ethnical diversity and the features of that diversity. In this paper it was tried to represent some socio-cultural suggestions, employing the positive experiences of countries with ethnical diversity and regarding opportunity-based approach of the Islamic Republic of Iran toward ethnical diversity and recommendations of the leaders of the revolution. The research method used here is a combination of documentary method with studying of resources and available studies, formation of elites’ panel, interviewing with elites. Also Smith’s general policy making model was used in the process.
