Purpose- The aim of this study was to investigate the mental image of local residents of tourism destination villages in Karaj city regarding the economic and social effects of tourism and its effect on tourism development tendency. Design/methodology/approach- This research is based on an applied and descriptive-analytical method. Data related to any of the variables have been collected through questionnaires and interviews. The statistical population of the study is the residents of the villages of tourism destination in Karaj city. Out of this, 365 local residents of the villages were selected according to Cochran formula as the sample population. To analyze the research findings, AMOS and SPSS software were used. Findings- The results of this study showed that the mental image of the local residents of the tourism destination villages in Karaj is positive about the economic and social effects of tourism development. Also, the satisfaction of local residents from economic dimensions of tourism with a factor of 0.77 compared to their social mental image with a factor of 0.70 has a greater impact on the local community's desire for tourism development. Research limitations/implications- The difficulty of crossing the mountainous slopes of Chalous Road, the unwillingness of some respondents in the studied villages for individual and social reasons, the lack of sufficient statistics and information about the province of Alborz due to the newly established and non-differentiated statistics from the Tehran province are among the limitations of the research. Practical implications- Neglecting local communities in tourism industry activities is a major bottleneck in participatory planning in order to achieve sustainable development of tourism. In this regard, planners and custodians of tourism in the studied villages should develop sustainable tourism to meet the needs and desires of local residents, while the development of sustainable tourism will be impossible without the participation of local residents and their loyalty toward tourists. In this way, the maximum satisfaction of the local community is realized as an indispensable necessity for the successful development of tourism. Originality/value- In this research, we tried to provide a comprehensive and systemic approach which is a geographical attitude to evaluate the tendency of local residents of target tourism villages of Karaj County about tourism effects. In addition, the effect of this attitude was examined on local community satisfaction using structural equation modeling.

One important question that the emergence of philosophical or rational Kalam has raised is what rationalism in the so-called Kalami (theological) schools actually means. This paper investigates the answers to the aforementioned question in Shi’a Kalam. Also, we have a comparative look at the philosophical Kalam and the rational one, concluding the identity of Shi’a Kalam with Shi’a philosophy. In this work, we have referred to three types of rationalism: personal, Vahmi (imaginal), and Hikmi (philosophical) rationalism. In short, our answer to the above question would be that, Shi’a Kalam – specially in Khaje Nasir’s works – is based on Hikmah (philosophy), and so, rationalism in this school does not refer but to this approach. This type of rationalism is in contrast to the personal or Vahmi rationalism. As a matter of fact, Those Mutakalims (theologians), who use Hikmi rationalism, don’t try to criticize philosophy or elicit from it; they just try to employ the principles, foundations, and results of Hikmah to explain, justify, and defend their religious beliefs

Introduction: This study was conducted to control hand tremors and decrease adverse effects due to the high field intensity in advanced Parkinson’s disease. We aimed at concurrently controlling two areas of Basal Ganglia (BG) in a closed-loop strategy.Methods: In the present research, two nuclei of BG, namely subthalamic nucleus and globus pallidus internal were simultaneously controlled. Furthermore, to enhance the feasibility of the suggested control strategy, the coefficients of the controller were determined using a hybrid version of the harmony search and cuckoo optimization algorithm. Results: The advantages of the applied method include decreasing hand tremors and applied electric field intensity to the brain; consequently, it leads to reducing adverse effects, such as muscle contraction and speech disorders. Moreover, the purposed controller has achieved superior performance against changing the parameters of the model (robustness analysis) and under noise tests, compared to other conventional controllers, such as Proportional Integrator (PI) and Proportional Derivative (PD).Conclusion: The employed approach provided an effective strategy to reduce hand tremors. It also decreased the delivered high field intensity to the brain; consequently, it reduced adverse effects, such as memory loss and speech disorders. It is important to ascertain the superior performance of the suggested closed-loop control scheme in different conditions and levels of tremor. Such a function was examined in terms of robustness against the variation of parameters and uncertainties. We also obtained time domain outcomes, i.e., compared with the state-of-the-art approaches.
