The purpose of this paper is to identify and analyze the structure and identifying the role of each of the key stakeholders of this ecosystem. In order to achieve this purpose, by studying the related literatures and the models presented in these literatures, a mobile government ecosystem conceptual model is proposed, where four new key stakeholders are introduced: new trends in over the top (OTT) services, innovation and innovators, advertisement and advertisers, and mediators. Then, a questionnaire is designed to verify the factors identified in the model and to examine the effects of these factors on the mobile government ecosystem. The questionnaire was distributed to a random sample of 400 experts, where 363 responses were collected, and analyzed based on structural equation modeling. The results show that with the exception of advertisement and advertisers, the three other key stakeholders have significant coefficients in the model. Manuscript profile -

Despite the importance of this issue, providing appropriate criteria for evaluating the influential behavior of users in recent studies has received less attention. For this purpose, in the first step, an innovative theory framework including two main dimensions: potential of the influence and the level of the influence is presented. Then, in order to define criteria for measuring each dimension, by providing a comprehensive and combined classification including three domains, user-based analysis, relationship-based analysis and content-based analysis, exploration techniques Social media has been examined to analyze the effective behaviors of users. In the following, according to the literature review, the criteria of "number of active users", “ranked of users based on the structural indexes and activity", “quality and the subjectiveness of content” have been defined to measure each of the aforementioned dimensions. The criteria proposed in this article are effective for creating dashboards to assess the value of users' influence in various businesses. It also a comprehensive roadmap has been provided for businesses about the data they need to collect and the required techniques to determine each of these metrics through a cross-disciplinary and academic classification of social media exploration techniques.

To do so we will study the discourse making process of IS throughout virtual space and Virtual Networks. This article argues that establishing a discoursive system and articulating ideational concepts that construct the positions of Self and Other and give them a hegemonic status is possible via virtual networks and with enjoying of media ploys. In this regard the main question of this essay is about the evaluation of the level of efficacy of these media arenas for IS and assesing the opportunities or by contrast the threats offered by them for IS’s activism. Our hypothesis is that virtual space is useful for IS and this group thanks to a professional approach to social networks and knowing the function of media, can establish a media terrorism by psychological operation and therefore complete its geopolitics actions.

In geopolitical crisis that the grounds for the conflict over the control and capture of one or more geographical values are significant, the crisis endures and sustains to some extent and cannot be easily resolved; since the issue of conflict belongs in the national interests upon which no compromise is feasible for the parties involved. The Republic of Azerbaijan, as an important actor in the geopolitical region of Southern Caucasia, faced a geopolitical crisis of the occupied territories due to Armenian territorial expansionism. It was a crisis that gained some international aspects following the intervention of some powers. Iran, as the most important neighboring country to Azerbaijan, has very often attempted to maintain her own position among regional and transregional actors through intervening in this crisis. Accordingly, this current study descriptively-analytically attempts to examine the question how Iran’s performance is assessed to resolve Karabakh’s crisis. The research findings demonstrate that Karabakh’s crisis has become complicated due to its being multi-faceted, its longevity and resistence, the plurality of the actors and the persuit of some particular geopolitical objectives by the mediators. Iran also follows up her own various objectives on the basis of the complex matrix of crisis and her geopolitical implications: prevention of triple coalition of Azerbaijan-Armenia-Turkey; averting the crisis spreading to her borders; playing an inhibitory role against the presence of transregional actors like Israel and U.S. accosting her borders.

Noise must be removed in a way that the main and important information of image is kept. Traditionally, the median filter has been the best way to deal with impulse noise; however, the image quality obtained in high noise density is not desirable. The aim of this paper is to propose an algorithm in order to improve the performance of adaptive median filter to remove high density impulse noise from digital images. The proposed method consists of two main stages of noise detection and noise removal. In the first stage, noise detection includes two global and local phases and in the second stage, noise removal is also done based on a two-phase algorithm. Global noise detection is done by a pixel classification approach in each block of the image and local noise detection is performed by automatically determining two threshold values in each block. In the noise removal stage only noisy pixels detected from the first stage of the algorithm are processed by estimating noise density and applying adaptive median filter on noise-free pixels in the neighborhood. Comparing experimental results obtained on standard images with other proposed methods proves the success of the proposed algorithm. Manuscript profile -

These product reviews are capable of enhancing communication among entrepreneurs and their customers. These reviews need to be extracted and analyzed to predict the sentiment polarity, i.e., whether the review is positive or negative. This paper aims to predict the human sentiments expressed for beauty product reviews extracted from Amazon and improve the classification accuracy. The three phases instigated in our work are data pre-processing, feature extraction using the Bag-of-Words (BoW) method, and sentiment classification using Machine Learning (ML) techniques. A Global Optimization-based Neural Network (GONN) is proposed for the sentimental classification. Then an empirical study is conducted to analyze the performance of the proposed GONN and compare it with the other machine learning algorithms, such as Random Forest (RF), Naive Bayes (NB), and Support Vector Machine (SVM). We dig further to cross-validate these techniques by ten folds to evaluate the most accurate classifier. These models have also been investigated on the Precision-Recall (PR) curve to assess and test the best technique. Experimental results demonstrate that the proposed method is the most appropriate method to predict the classification accuracy for our defined dataset. Specifically, we exhibit that our work is adept at training the textual sentiment classifiers better, thereby enhancing the accuracy of sentiment prediction. Manuscript profile -

A multi-objective-based optimization technique called Multi-Objective Particle Swarm Optimization (MO-PSO) is introduced in this paper for image segmentation. The multi-objective Particle Swarm Optimization (MO-PSO) technique extends the principle of optimization by facilitating simultaneous optimization of single objectives. It is used in solving various image processing problems like image segmentation, image enhancement, etc. This technique is used to detect the tumour of the human brain on MR images. To get the threshold, the suggested algorithm uses two fitness(objective) functions- Image entropy and Image variance. These two objective functions are distinct from each other and are simultaneously optimized to create a sequence of pareto-optimal solutions. The global best (Gbest) obtained from MO-PSO is treated as threshold. The MO-PSO technique tested on various MRI images provides its efficiency with experimental findings. In terms of “best, worst, mean, median, standard deviation” parameters, the MO-PSO technique is also contrasted with the existing Single-objective PSO (SO-PSO) technique. Experimental results show that Multi Objective-PSO is 28% advanced than SO-PSO for ‘best’ parameter with reference to image entropy function and 92% accuracy than Single Objective-PSO with reference to image variance function.

This study was conducted with the aim of investigating the impact of visual media on the occurrence of deviations and crimes among children and teenagers and discussing ways to prevent it. Method: The present study was conducted using descriptive-analytical method and using documentary (library) resoureces. Results: Visual media, by getting the audience used to the events, desensitization and inattention, etc., provide the basis for learning violence from the media. Younger people are much more influenced by the media, and this is due to their realism, their incomplete cognitive ability, and their inability to relate the scenes of the program to the final result. With the development of global media outside the control of governments, such as satellites and the Internet, and providing inappropriate models, negative training, airing programs with no purpose, not paying attention to the age of the audience, and not showing the results of actions, the role of the mentioned media in the spread of crimes and deviations such as violence, running away from home, free sexual relations, and sexual addiction are undeniable, especially among young people. Conclusion: Due to the negative impact of visual media on children and teenagers in terms of creating grounds for deviance and committing crimes, it is necessary for the government, people, family and mass media to make a joint effort to deal with the content of inappropriate and replace it with healthy programs and entertainment.

But there are many theoretical weaknesses in the development of these companies, especially in their conceptual models. The purpose of this study is the modification of the conceptual model to improve the development path of these companies. A systematic conceptual model for the development of companies, with considering the strategic role of the media, is the purpose of this paper. Firstly, the definitions, indicators, dimensions of knowledge-based companies, and the previous efforts related to them are discussed. The type of research is qualitative and is analyzed based on Grounded Theory methodology. The conceptual model is based on field observation and systematic interviews with 21 managers related to the development of knowledge-based companies, science and technology parks, and growth centers in Iran. The results show that the development of knowledge-based companies is due to the strategic role of media, which is included education, culture, information, and guidance. According to the development strategy of a knowledge-based company, the consequence of the process is enhanced by television and internet. On the other hand, the process is affected by base conditions such as culture, supervision, economics, media activities, as well as environmental conditions such as the academic capacity, websites, intellectual property, laws, sponsorship, Internet, industry, and politics. Trans nationalization of products, reduction of dependence, improvement of product quality, policy, decision making, strategy development, promotion of activities, employment growth, are the consequences of media's role in the development of knowledge-based companies.

This descriptive survey study, therefore, sought to investigate the effect of social media advertisements, audience participation, and word-of-mouth advertising on European tourists’ brand resonance through the cognitive and emotional images as well as attitudinal and practical loyalties in social media. The population of the study comprised of the European tourists who visited Tehran from March to June 2019. The Cronbach’s alpha coefficient was used for the inferential analysis of the collected data, and KMO was applied to measure the internal consistency of the tool used. Moreover, Bartlett’s test was administered to confirm the sampling adequacy and the correctness of factors separation. The structural equation modeling method was also used for identifying the relationships among the variables. The results of the study indicated that social media advertisement, audience participation and brand awareness were effective on the cognitive image of the European tourists who visited Tehran, and that audience participation and word-of-mouth advertising affected their emotional image. It was also found that cognitive and emotional images would affect the attitudinal and practical loyalties which in turn would influence the brand resonance that could be helpful in attracting tourists provided that it is accompanied by well-defined plans in terms of creativity and innovation in advertising, knowing the audience, and choosing appropriate advertisements to be published in social media.

At the first stage, the main elements of the model were extracted from the related literature review and the Osterwalder and Pigneur’s business model framework. At the second stage, to evaluate and prioritize the identified elements, a questionnaire was developed and administered on 119 experts who were selected through snowball sampling. The collected data were then analyzed, using Smart PLS software and the elements were imbedded in the model in order of their importance. Applying multiple case study method, the business model of seven tourism companies who managed to successfully employ the potentials of social media to their benefit were analyzed in the final stage to validate the business model proposed by this study. The findings indicated that active presence in social media would affect the customer-related elements more than those of the supplier-related ones. In other words, the elements related to the relationship with customers, cost structure, value proposition, and distribution channels would be affected more than the elements related to revenue streams, key resources, key activities, and key partnerships.

The population of this applied survey study comprised of Ramsar visitors who discussed it as a travel destination on social media and had used social media to choose Ramsar as a tourist destination. In this regard, 73 media sources where Ramsar had been discussed were selected using a judgmental sampling method. The required data were collected through electronic questionnaires from 384 visitors (out of 450 visitors) who were selected through non-probability convenient sampling. The collected data were then analyzed via SmartPLS software using structural equation modeling and path analysis technique. The findings of the study suggested that a community’s social media-based destination brand had a positive impact on the visitors’ enjoyment of the place, loving the place, and positive surprise towards the destination, persuading them to participate in the co-creation of values and thus revisit the place.

The destruction of the environment is happening at an incredible rate these days. Today, the media play an important role in informing and educating the environment, so the influence of the people on the media affects the type of behavior and attitude towards the environment. The first step in promoting the general culture of environmental protection requires environmental education in all sectors, especially children and adolescents as ambassadors of the environment in society. It deals with their impact on the behavior and culture of the people and society. In order to promote the general culture of environmental protection in the country, for this purpose, the views of experts, books, study and research background will be studied. Control of environmental factors plays a key role in promoting environmental health, and environmental pollutants that have a certain diversity, extent and complexity can endanger environmental health, so since the media is one of the most important means of mass communication, they should be Used to control environmental factors that enhance people's culture in preserving the environment.

Today with the intelligent use of media, it is possible to introduce social issues, prevent and confrontation. Addiction is one of the most common social issues that trouble our country. Therefore, addiction prevention can play an important role in reducing social harm. According to its social responsibility, the national media has always sought to confront and fight against social harms, including addiction. The documentary "Shock" was among the programs that were produced and broadcasted on the third channel of national TV in order to deal with addiction. The present research was conducted with the aim of analyzing the performance of Shock documentary. The theoretical framework of this theory was based on theories of social responsibility, framing and Tannehill's health model. The research method, quantitative content analysis and data collection tools were reverse questionnaire. 8 programs in the period of 18 months from the beginning of 2019 to September of 2019 were selected purposely. The findings show: the type of attitude towards addiction is mainly patient-oriented and the approach of the program emphasizes primary prevention. The way of modeling about the prevention of addiction, introduction of risk factors, and industrial drugs have received more attention. Also, according to the results of this research, friends and therapeutic motivations were among the factors of tendency towards addiction. Manuscript profile -

How MoreToday, social networks have become a prominent source of news, significantly altering the way people obtain news from traditional media sources to social media. Alternatively, social media platforms have been plagued by unauthenticated and fake news in recent years. However, the rise of fake news on these platforms has become a challenging issue. Fake news dissemination, especially through visual content, poses a significant threat as people tend to share information in image format. Consequently, detecting and combating fake news has become crucial in the realm of social media. In this paper, we propose an approach to address the detection of fake image news. Our method incorporates the error level analysis (ELA) technique and the explicit convolutional neural network of the EfficientNet model. By converting the original image into an ELA image, it is possible to effectively highlight any manipulations or discrepancies within the image. The ELA image is further processed by the EfficientNet model, which captures distinctive features used to detect fake image news. Visual features extracted from the model are passed through a dense layer and a sigmoid function to predict the image type. To evaluate the efficacy of the proposed method, we conducted experiments using the CASIA 2.0 dataset, a widely adopted benchmark dataset for fake image detection. The experimental results demonstrate an accuracy rate of 96.11% for the CASIA dataset. The results outperform in terms of accuracy and computational efficiency, with a 6% increase in accuracy and a 5.2% improvement in the F-score compared with other similar methods.
