The research population consisted of experts familiar with the issue in Hormozgan province in 2020, out of whom 20 were chosen as the sample through purposeful sampling method as the sample. The research instrument of the qualitative part was based on domestic and international research, wide the research instrument for the quantitative section was a 20- item questionnaire based on the qualitative part. In the qualitative section, using fuzzy Delphi method, the factors were identified and confirmed or screened, while they were ranked in the quantitative section using fuzzy DANP method. Findings: The results indicated that after three rounds of fuzzy Delphi, 15 indices were identified across six elements including technical/technological, personal user, social, customer orientation, perceived value, and reliability. Other results based on the fuzzy DANP method indicated that the user personal elements, plus social elements, reliability, perceived value, technological/technical, and customer orientation had the largest weights respectively. In addition, validity, personal innovation, and online experience claimed the first to third ranks in terms of weight. Conclusion: The results indicated the effective role of three elements of personal user, social, and reliability in comparison to other elements, which could be exploited by managers and planners to improve digital marketing based on mobile commerce.

Purpose: The aim of this study was to compare the effectiveness of Fernald’s multisensory training and computer game training on dyslexia in primary school students with learning disabilities in Ahvaz. Methodology: This study was applied in terms of purpose and in an experimental framework (pre-test-post-test design with control group). The statistical population in the present study consisted of all elementary students with learning disabilities in the first and second grade of elementary learning centers in Ahvaz in 2019. The sample consisted of 45 students with learning disabilities in the first and second grade of elementary school. The research instrument included Wexler (1945) dyslexia questionnaire. Data were analyzed using repeated measures analysis of variance and multivariate covariance of Manqua and ANCOA. Findings: The results of data analysis showed that Fernald’s multisensory training reduced dyslexia in elementary students with learning disabilities in the experimental group (1) compared to the control group and training in the use of computer games reduced the dyslexia in elementary students with learning disabilities in the experimental group (2). In comparison with the control group, it was found that there is a difference between the effectiveness of Fernald’ multisensory training and computer game training on dyslexia of elementary students with learning disabilities and Fernald’s multisensory training compared to computer game training in elementary students with dyslexia. Learning disabilities were more effective. Conclusion: As a result, it can be said that Fernald’s multisensory training methods and computer game training reduce the dyslexia of elementary students with learning disabilities and Fernald’s multisensory training is a more effective method to reduce the dyslexia anger of elementary students with learning disabilities

The research sample in the qualitative part according to the theoretical saturation principle were estimated 13 people who were selected by purposive sampling method and in the quantitative part according to Cochran’s formula were estimated 385 people who were selected by cluster random sampling method with respect to classes (number of staff in universal branches). To collected data in the qualitative part used from interview and in the quantitative part used from researcher-made questionnaire (51 items) which the its content validity was confirmed by experts and its convergent validity by average variance extracted indicator was confirmed and its reliability was obtained by Cronbach’s alpha method 0.84. To analyze data were used from methods of open, axial and selective coding and exploratory factor analysis in SPSS-22 software. Findings: The findings of the qualitative part showed that suitable leadership had 79 concepts, 63 categories and 7 dimensions and new missions of higher education dad 20 concepts, 15 categories and 3 dimensions. The findings of the quantitative part showed that the suitable leadership model to achieve new missions of higher education had 51 indicators or items and 15 components.

Conclusion: Based on the findings of the present study, higher education specialists and planners can design and implement programs to realization the new missions of higher education.

This study examines whether the firms’ leverage adjustment speed is influenced by real and accrual-based earnings manipulation over the period 2006-2019. We find evidence suggesting that the leverage adjustment speed in firms with a higher level of real and accrual-based earnings manipulation is slower than that of other firms. Specifically, we show that under-levered (over-levered) firms with a higher level of earnings manipulation tend to adjust their actual leverage toward an optimal level, faster (slower) than that of other firms. These results are robust to different metrics for real and accrual-based earnings management, an alternative set of leverage determinants, alternative sample periods, and various estimation methods.
