Success at university depends on the possession of outstanding writing skills. Yet of all language skills, writing is the most arduous to master and the situation gets even worse in the case of second or foreign languages. The current study investigated the suitable ways to overcome the difficulties students of English face with writing especially in terms of vocabulary items and spelling mistakes by exploring the effects of adapting autocorrect and spell- checkers technologies on their writing skills. The research data comes from an experiment conducted at Adrar University, south of Algeria, in which 18 LMD (Licence-Master-Doctorat, equivalent to the BMD, BachelorMaster-Doctorate) students utilize autocorrect and spell-checkers as assistive technology. The finding of the experiment shows that the use of assistive technology has perceptible effects regarding the quality of students’ production as these technologies displace the attention from worrying about spelling mistakes to other aspects of writing. The paper also proposes some suggestions to improve writing skill at the level of Algerian Higher educational institutions (HEIs).

Mental health plays an essential role in ensuring the dynamism and efficiency of any society. Entering the university is a challenging life event for young adults; because students encounter changes in social communication, expectations, and roles. As a result, they are susceptible to experiencing stress and anxiety that could affect their functions. The present study was done to present the causal model of the effect of intrinsic and extrinsic aspirations on mental health about the mediating role of irrational beliefs. The research method was descriptive correlational. To do this, 250 students from Allameh Tabatabaei University were selected via available sampling and then answered a self-report questionnaire consisting of four Factors of Irrational Beliefs Test-Ahvaz (4IBT-A; Ebadi and Motamedi, 2005), General Health Questionnaire (28- GHQ; Goldberg & Hiller, 1979), and Aspiration Index (AI; Grouzet et al., 2005). Data analysis was administered in two parts of latent and observed variables via structural equation modeling using AMOS software. The results showed that extrinsic aspirations positively predict irrational beliefs and intrinsic aspirations negatively predict irrational thoughts; intrinsic aspirations, directly and indirectly, affect mental health; but extrinsic aspirations have no direct effect on mental health; instead, they can reduce students' mental health mediating irrational beliefs. Also, irrational beliefs had a causal and immediate impact on mental health.

Introduction: Educating people in different ways is one of the aspects of moral education. Education that plays an important role in the destiny of man and society. One of the issues in moral education is how to involve moral teachings in the political relations of countries. The purpose of this research is to investigate the ethical components affecting political development in higher education. Material and Methods: The current research was applied and implemented in a mixed manner. Thematic analysis method was used in the qualitative part. The statistical population was experts in the field of higher education (administrators and faculty members of universities), from among whom 10 people were selected by snowball sampling. The interview tool was semi-structured and the data was analyzed by coding method and MAXQDA software. In the quantitative part, the method was descriptive-correlation. The research community included experts in the field of higher education and international relations (academic faculty members, cultural advisors, and experts from the Ministry of Foreign Affairs), among whom 50 people were selected in an improbable and accessible way. The data were analyzed using structural equations and pls software. Results: The results of the qualitative part indicated 32 open codes and 6 core codes, which were categorized into 3 categories of educational relations factors at the international level, moral policy, civil and social development. The results of the quantitative part also indicated the appropriate fit of the model, so it can be said that ethics and ethics approaches in higher education can be effective in political development. Conclusion: The results of the findings show that in addition to the desire of countries to develop relations based on respect and moral policy, there are factors in three areas of educational relations at the international level, moral policy, civil, scientific and social development in higher education; Among them: relations based on respect, expansion of international relations, attention to human dignity, freedom, attracting participation, meritocracy, attention to scientific and civil institutions have an effect on political development

The coronavirus pandemic has had some unexpected benign effects (including a large drop in air pollution and levels of nitrogen oxides in UK and elsewhere, and a smaller drop in global carbon emissions), which raises the problem of how to sustain and build on these unexpected gains. These gains could easily be lost when economies and road transport return to something like their previous condition. But if governments and industries are inspired to reduce automobile emissions to match the levels of the spring of 2020, gains such as these could become recurrent, and many more lives could be saved. Further, if (with greater effort) carbon emissions could remain reduced, then future generations could be saved from sea-level rise, extreme weather events, and even from the spread of tropical diseases. Such a prevention of disease would be an ironic but welcome gain from a pandemic.

This study aims at getting a better performance for optimal stock portfolios by modeling stocks prices dynamics through a continuous paths Levy process. To this end, the share prices are simulated using a multi-dimensional geometric Brownian motion model. Then, we use the results to form the optimal portfolio by maximizing the Sharpe ratio and comparing the findings with the outputs of the conventional model. To examine the robustness of the results, we have evaluated its performance for different investment horizons and various volumes of price information over a long period (approximately twenty years) in the Tehran Stock Exchange (TSE). Findings indicate that within the trading dates spanning the interval 24-Mar-2001 to 19-Sep-2020, the return of the portfolios obtained from applying this simulation scheme for maximization of Sharpe ratio is (244% on average) higher and their risk (standard deviation) are lower (1227% on average) than those realized by the conventional methods. Additionally, a comparison of the simulation approach with a performance of the actual market portfolios indicates that the Sharpe ratios of the simulation method are higher (0.055% on average) than those resulting from the total market performances. The results of the stochastic dominance test show that our proposed strategy has a first-order stochastic dominance (FSD) over the conventional one and market portfolios, that means at each level of cumulative distribution, the Sharpe ratio of our method is higher, and as FSD test makes no assumptions about the curvature of investors' utility functions, these results do not depend on the degree of risk aversion of investors, and as long as investors prefer a higher Sharpe ratio, they would be better off if they follow our proposed strategy.

The present study was conducted with the aim of scenario planning of the future of strategic agility in the Ministry of Sports and Youth of the Islamic Republic of Iran through using future research. The method used in this research is scenario-based planning, which is designed and performed in eight steps. The method of data collection in this qualitative study was based on interview, expert panel and Delphi survey. Twenty experts with specialized knowledge or practical experience were selected as the participants of the research through using snowball sampling. In the first part, acceleration to affairs and processes, the application of new managerial competencies, innovative and agile organizational structure, the use of emerging technologies, and the existence of a system of encouragement and punishment based on strategic agility were identified as key drivers. In the second part, it identifies and describes possible and compatible scenarios based on the drivers and related uncertainties, and it was found that out of the two proposed scenarios, only one scenario is in a promising situation. According to this scenario, by increasing the speed of the affairs and processes, the use of new managerial competencies, agile organizational structure, emerging technologies, and the existence of an incentive system, we can see the improvement of strategic agility in the Ministry of Sports and Youth.
