The purpose of this research is to achieve a better understanding of the development of organizational capabilities of knowledge-based companies and to improve their export performance. Also, this study aims to help the performance of these companies in international markets by measuring international orientation.

In order to achieve the stated goals, a questionnaire was distributed among 219 knowledge-based companies that had a history of exporting, of which the information of 205 questionnaires was used for analysis using structural equations and Smart PLS software.

Based on the findings of this study, it can be seen that the three variables of international orientation, innovation capabilities and export performance have a positive and significant relationship with each other. It is also argued that the international orientation has an impact on six of the seven variable dimensions of innovation capabilities, and it does not have a significant relationship only with the dimension of research and development capacity. In addition, from these dimensions, only two dimensions of research and development capacity and marketing capacity have a significant relationship with export performance.

Originality/Value:

 The results of this study confirm the findings of the previous literature, which acknowledged that there is a strong and positive relationship between the company's capabilities and their performance in international markets. This study provides insights into establishing international orientation as an important internal capability that can contribute to the superior export performance of these companies. The moderating effects are important because domestic drivers are found to influence the faster internationalization of new businesses.

In the marketing literature, considerable efforts have been made to identify factors influencing impulse buying such as consumer characteristics, store characteristics, situational stimuli, and product characteristics. Most previous research in the field of online impulse purchases has focused on the effects of stimuli or content produced by the marketer. Regarding the effect of online comments on consumer behavior, studies have been conducted which mainly investigated the effect of online comments on the intention and behavior of consumers at the individual level. In fact, few researches have simultaneously examined and compared the environment of an online store from the two perspectives of the ability to create a flow experience in the consumer and the social impact (for example, online comments and its dimensions) on impulse buying. Considering this research gap, this research seeks to investigate the formation of utilitarian and hedonistic values of the consumer in two ways: 1) qualitative and quantitative dimensions of online reviews on the website and 2) the experience of the consumer's flow while using the shopping website
The present study, at the purpose, is applied research and at data collection, it is a descriptive-survey one. The statistical Population of this study is 350 individuals from tehran customers of Digikala and convenience non probability sampling technique is used as a sampling method. We collected the responses through online questionnaires applying social networks. In this research, the data collection tool is a standard questionnaire with 35 questions, the questions of which are adapted from reliable research sources and the items are valued according to the Likert scale from 1 to 5. Structure equation modeling with Smart PLS3 was employed to verify and validate the research model.
 The results of this study show that quantity of online reviews does not have a positive effect on utilitarian and hedonic value and quality of online reviews has no positive effect on hedonic value and also the effect of utilitarian value on browsing was not confirmed. Based on the findings of the research, other hypotheses presented in this study were confirmed. Therefore, from the point of view of the ELM theory, which has divided the paths of influence on decision-making and persuasion into two main paths (based on reasoning) and secondary paths (based on side and surface symptoms) and also considering that in previous studies, the quality of opinions as the main factor and pointed to the number of comments as a secondary factor, it can be concluded that customers were not influenced by external signs such as the number of comments in their information processing and decision-making, and in fact, the justification and persuasion in deciding to buy from the secondary route that It is based on superficial and intuitive signs, it is not done and it was also determined that all dimensions of the flow experience (perceived control, concentration and cognitive enjoyment) have a significant and positive effect on the formation of the utilitarian and hedonic perceived value of the customer based on research hypotheses.
The results of this research indicate that the formation of the Urge to buy impulsively is achieved through the hedonic value of the customers. On the other hand, users' Reviews have not been effective in creating hedonic value, and the influence of the hedonic value of customers has been solely from the experience of the flow and content of the website environment. As a result, based on the findings of this research, the content produced by online store managers has had a greater impact on the formation of the Urge to buy impulsively compared to the content produced by customers. Therefore, it is suggested that website designers use templates that encourage users to comment on the functional features of the product in order to increase the quality of comments. Marketing managers of online stores can strengthen the user's sense of control over the website environment by providing useful and updated content regarding products and services, proper classification and arrangement of product categories, and providing simple and quick access to content for customers. On the other hand, website designers should pay attention to the habits, behaviors and searches of users in order to focus the user on the website in order to create functional and pleasure-seeking value for customers and try to provide content with quality and accuracy and maintain customer focus. The low speed of searching and loading web pages, irrelevant advertisements, flashing texts and images, and ineffective links that open new pages are among the things that divert the focus and attention of customers and should be considered in the design of sales websites. In order to stimulate users' cognitive enjoyment of the website environment, site designers should work on energetic and lively graphic and decorative designs. The colors used on the website pages should have a suitable harmony and in the introduction of the product features, it is suggested to use images, videos and sounds in addition to the texts, so that the user can have a real experience of the virtual environment.

Nowadays, the use of social media has become very important in the development of businesses. Managers and business leaders are trying to increase the engagement of customers in their social media. This is not only true for large companies and businesses, but it is also necessary for small businesses and the most basic stages of their growth (such as the businesses created based on Instagram); Therefore, the current research was conducted with the aim of formulating a pattern of social media marketing strategies to increase the engagement of customers in the leather industry. The present research is among the qualitative researches with content analysis method. The sampling method was judgmental and purposeful, and in order to collect data, 10 semi-structured interviews were conducted with social media officials and strategists of premium brands in the leather industry. Based on data analysis, 6 main themes and 20 sub-themes were extracted. Also, a model was presented in order to model customers' association with the brand. Based on the findings of the research, using the relevant platform (including 2 sub-themes), keeping up the virtual page (including 4 sub-themes), measuring performance (including 3 sub-themes), targeted use of social media (including 3 sub-theme), coping with challenges (including 6 sub-themes) and focusing on strengths (including 2 sub-themes) were the main strategies discovered in order to increase customer engagement in social media.

Today, digital transformation has caused changes in the business environment through the emergence and development of new technologies, while changing the needs of customers. In this context, disruptive innovation as one of the most critical factors that ensure the success of companies in the markets has been noticed by entrepreneurial managers. Due to the lack of studies, in this research, the impact of entrepreneurial orientation(EO) and digitalization strategy(DS) on disruptive innovation(DI) has been investigated.

The current applied research is descriptive-survey in terms of its nature and method. The researchers focused on the managers of production companies in Tehran as the statistical population of the study. The sample size was calculated with G-Power version 3 software, 313 people. Data were collected by non-random sampling method, and using a standard 33-question questionnaire with online survey. To assess the reliability and validity, and model fit, confirmatory factor analysis was used. Hypotheses were also tested with structural equation modeling technique and using Amos version 24 software.

The results showed that EO has a positive and significant effect on DI. Also, the strengthening role of DS as a mediator, and the weakening role of this variable as a moderator was also confirmed in this relation.

Depending on the level of EO of companies, DS can be considered as a lever or a cage for DI. In this context, the implementation of any level of DS should be calibrated based on the level of EO of managers on DI, in order to prevent the creation of a strategic cage that can limit innovation.

Advertisers are interested in the emergence of new marketing channels, including online and Internet-based platforms, and they consider it as an opportunity to increase brand awareness and run advertising campaigns. The attitude toward advertisements has always been the subject of researchers' attention. As the results indicate, in recent years, the general attitude towards advertisements has become negative. Nevertheless, researchers in different countries have reached different results. As a result, the attitude towards mobile advertising should be scrutinized. Also, conducting research and presenting literature from studies native to Iran will be useful for preparing and relying on mobile advertising.

In this research, the Q methodology has been used to identify customers' attitudes toward mobile ads. The statistical population of the study was people in Tehran who had set up three free apps on their smartphones. The sampling method was convenience sampling. The data obtained from the participation of 32 people were analyzed using the Q factor analysis by the SPSS 22.0 software. The Q method is known as the link between qualitative and quantitative methods. Following the steps of the Q method, after determining the subject with the title of customer attitude towards advertising and reviewing the literature on the subject, the discourse space was evaluated and summarized. In addition to evaluating research articles and the literature (second-hand sources), professors in the field of marketing and advertising were consulted (first-hand sources). Finally, i36 Q expressions were created. The reliability of the Q classes was evaluated by test-retest. After the creation of a Q table, three participants completed the table again. The correlation between the responses was 0.812. This number indicates the reliability of the Q expressions.

Threatening as the first attitude type: Based on the obtained results, terms 7, 21, 28, 26, 22 and 2 were positive views, and 34, 20, 30, 25, 17 and 10 were the negative views of this group members. The members had a negative overall attitude toward in-app advertising. The people in this category believed that in-app ads are likely to be malware, and opening them will risk the security of phones. They install spy applications on phones automatically, which is a threat to the performance of the mobile phone.Entertaining as the second attitude type: Based on the obtained results, terms 22, 26, 11, 16, 6 and 8 were positive views, and 9, 1, 4, 7, 2 and 10 were the negative views of this group members, so the members had a positive overall attitude towards in-app advertising. The people in this category believed that in-app advertising shows users amazing offers that are often entertaining. They are credible, visually attractive, and informative. Privacy in these advertisements is important to them. However, they felt that the possibility of lying, spying, and hacking is low, and ultimately they are not annoying.Annoying as the third attitude type: Based on the obtained results, terms 10, 14, 33, 31, 9 and 26 were positive views, and 27, 32, 6, 16, 8 and 11 were the negative views of this group members, so the members had a negative overall attitude towards in-app advertising. The people in this category believed that in-app ads are annoying, do not consider user privacy, and must be removed immediately. Moreover, they are time-consuming. These people would not allow the app creators to show ads as a cost of using free apps, and they would not enjoy entertainment and trust information in such ads.Misleading as the fourth attitude: Based on the obtained results, terms 5, 6, 13, 16, 19 and 18 were positive views and 8, 20, 9, 11, 17 and 36 were the negative views of this group members. The members had a negative or neutral overall attitude. They believed that in-app ads are liars, and link to inappropriate sites. They also believed that, although ads are visually attractive and exciting, they are doubtful. This group also does not want to see ads to access free apps and does not find these advertisements entertaining, informative, and valuable. However, they did not feel so annoyed by these ads, and they just skipped them.

According to the classification of the attitude of Iranian users towards in-app advertising of smartphones, the following suggestions are provided for the successful implementation of advertising campaigns on mobile applications:1) Ask for permission before showing ads.2) Stop showing more ads after the user closes an ad.3) Show ads in the form of entertainment or game to make them more likely to be opened.4) Use beautiful but real (believable) graphic images and avoid 18+ images that create a sense of threat in the mind of the audience.5) Ads should be related to the installed program or similar applications, and unrelated ads should be avoided.6) Offer ads only on applications whose owners are careful in showing related ads; otherwise, the audience will group your advertisement with some inappropriate ads.7) Ads should be small and closeable because the compulsion to see, hear and play an ad will gradually reduce the value of the brand in the eyes of the customers.8) If advertisements offer gifts or discounts, you must be committed to it and avoid fraudulent advertisements.9) Although personalization and the use of artificial intelligence are recommended, revealing detailed information about customers like marital status, age, place of residence, etc. leads to a feeling of fear and threat, and he will uninstall the application.10) Being entertaining is more effective than being informative. As a result, it is suggested to pay attention to being attractive in a way the customers like.11) Advertising campaigns should try to choose related applications as their ad channel. Mass advertisement is not going to work.Finally, researchers are suggested to investigate the difference between the generations of respondents and their attitudes towards other advertisement channels. It will also be interesting to conduct research that categorizes the paradigms of attitude towards advertisements in Iran.

With the emerging of experience economy, customer experience has been used as one of the main concepts in experiential marketing, as well as a creative basis for predicting customer purchase intention. In this context, marketing studies show that today, consumers want active participation in creating brand experiences. Therefore, interest in investigating the consequences of brand experience is increasing rapidly. However, the brand experience and its effects remain largely unknown. Considering the mediating role of brand attitude, trust, and attachment, this study investigated the effect of brand experience on purchase intention. This research is applied in terms of purpose and has a descriptive-survey nature. The studied population were consumers of beauty and personal care products in Tehran. The sample size was calculated with G-Power 3.1 software of 355 people, and the available non-probability method was used for sampling. Structural equation modeling and Smart PLS 3 software were used for data analysis. After testing the hypotheses, the direct effect of brand experience on brand attitude, trust and attachment, as well as all these variables on purchase intention, was confirmed. Likewise, the mediating role of brand attitude in the relationship between brand experience and purchase intention was confirmed, but the mediating role of trust and brand attachment was rejected. The results provide several theoretical and managerial implications to help business managers to provide a better brand while increasing sales through creating positive experiences for customers.

With the rapid advancement of technology, it has become possible to track consumers' behavior on the Internet. Consequently, marketers can tailor advertisements to align with consumers' needs and characteristics. However, this raises concerns about consumer privacy. Some researchers have concentrated on the positive aspects of Online Behavioral Advertising (OBA), while others have delved into its negative implications. Therefore, this study seeks to examine the impact of cognitive and affective factors on consumers' behavioral responses to OBA. It aims to explore both the positive and negative facets of this advertising approach.

This survey research adopts an applied approach and targets Internet users from Tehran Universities as the study population. A total of 385 questionnaires were distributed among the sample members. To identify individuals with experience in viewing online behavioral advertisements, a screening question was placed at the beginning of the questionnaire. Of the respondents, 299 reported having seen OBA in the past six months during the survey, and subsequently answered the questions. Descriptive statistics were conducted using SPSS 26, while Smart PLS3 software was employed for inferential statistics.

The findings reveal that perceived personalization positively influences perceived relevance, diminishes perceived intrusiveness, and enhances behavioral responses to advertisements. Additionally, information control demonstrates a negative impact on perceived intrusiveness and privacy concerns, while persuasion knowledge exhibits a positive correlation with privacy concerns. Consumers possessing high levels of persuasion knowledge express increased privacy concerns regarding OBA. Mitigating privacy concerns leads to improved attitudes toward OBA, subsequently enhancing behavioral responses to advertisements. However, privacy concerns do not directly impact behavioral responses to advertisements. Moreover, perceived relevance and perceived intrusiveness serve as mediators in the relationship between perceived personalization and behavioral responses to advertisements.

OBA, due to its relevance to the consumer's needs and the reduction of perceived intrusiveness, increases the response to advertisements (a direct and indirect positive mechanism, respectively). This method of advertising is a suitable approach to increase the response rate to online advertisements. Allowing users to control their information will reduce perceived intrusiveness and privacy concerns. Improving consumers' persuasion knowledge by emphasizing the benefits of OBA will reduce their privacy concerns and improve their attitudes toward it, ultimately increasing behavioral responses to the advertisements. In contrast to some past research, privacy concerns do not affect behavioral responses; this may be because of the nature of OBA, which uses different data compared to personalized advertising. Also, OBA is known as a double-edged sword, but the effect of the negative side (privacy concern) is less than the positive side (perceived relevance). This research will contribute to the literature on personalized advertising, specifically online behavioral advertising, and include practical implications for marketers, brand managers, and advertising agencies.

Air pollution as one of the important problems of urbanization and industrial life has affected the health of society and the World Health Organization has introduced it as one of the effective factors in causing cancer. In this study, the effects of short-term exposure related to mortality and diseases associated with particulate matter less than 10 microns (PM10) in Shiraz during 1396-1397 have been investigated. This is cross-sectional applied research based on field studies and modeling of experimental conditions. In this study, the concentration of PM10 pollutants for the years 1396-1397 was measured hourly and daily using a Grimm Instrument from the four air pollution measuring stations of the Environment Organization (Kazerun Gate, airport, Setad, and science and technology park), and the relevant data were analyzed using AirQ + software. The results showed that the highest distribution of PM10 pollutants in Shiraz was in the range of 30-40 µg/m3and the highest mortality rate attributed to this pollutant was due to respiratory diseases (4.34 and 3.9% of cases) and hospitalization due to heart diseases (3.2% and 2.95% of cases) are in second place. Also, the total death rate attributed to PM10 pollutants in these years has been estimated at 278 and 249, respectively. Therefore, due to the significant health effects of this pollutant, it is necessary to plan and enact comprehensive measures to combat PM10 emissions and reduce and control its adverse effects in order to maintain the health of citizens.

This study analyzes the effect of business intelligence on firm performance by considering the mediating role of knowledge sharing, organizational innovation, and competitive advantage.

The following research is applied research. Since this study examines the relationship between several variables, for example, the relationship between business intelligence variables on firm performance, and it does not manipulate these variables, it is descriptive correlational research. The statistical population of this research is small and medium entrepreneurs in Tehran province. The method of data collection is a questionnaire. The number of items in the questionnaire is 42, the sample size of which is 202 questionnaires, and all of them have been completed rightly. Structural equation modeling and SPSS and PLS 3 software were used to analyze the data.

This research has 7 hypotheses, 5 hypotheses of the research have been confirmed and the findings indicate that business intelligence has an impact on the sharing of competitive knowledge and firm performance. This shows that managers should pay attention to the implementation of business intelligence in their organization to enhance their performance and increase their ability to respond to external risks and challenges. The findings of this study also show that knowledge sharing impacts competitive advantage and finally, competitive advantage impacts firm performance.

Originality/Value:

 The results of this study showed that the use of business intelligence in the organization and small and medium entrepreneurship will lead to increased performance, competitive advantage, and increased knowledge sharing. This research can help organizations to use business intelligence in their activities in a more specialized way.

The purpose of this study was to investigate the effect of business intelligence, foreign market knowledge and entrepreneurial characteristics on the speed of internationalization with the mediating role of organizational agility in SME pharmaceutical companies in Alborz province. The statistical population of this research was formed by those who hold a position and responsibility in SME pharmaceutical companies. In fact, they are decision makers. Therefore, it is possible to consider those who are part of the managerial positions, assistants, supervisors, senior decision makers, board members, and experts of different departments of SME pharmaceutical companies of Alborz province as members involved in the statistical population. did In this research, Klein's approach was used to determine the sample size. He believes that 10 or 20 samples are necessary for each variable. Considering the presence of 8 variables in the research, the sample size is estimated to be 20 times that is 160 samples. Non-probability sampling method was used. A researcher-made questionnaire was used to collect data and its Cronbach's alpha coefficient was 0.950, which indicates the reliability of the research tool. Also, the KMO test was confirmed in the validity of the research instrument construct. Smart PLS software was used to analyze the data and test the research hypotheses. The research findings out of the ten mentioned hypotheses show the confirmation of seven hypotheses and the rejection of three hypotheses. The foreign market knowledge construct did not show any positive and significant relationship with organizational agility structures and the speed of internationalization and also its mediating role was not confirmed. But other structures, namely business intelligence and entrepreneurial characteristics, showed a significant and positive relationship with organizational agility and the speed of internationalization, both directly and indirectly through the mediating role of organizational agility.

In this paper, a new adaptive controller based on the barrier function is designed for high-order nonlinear systems with uncertainties in mind. Accordingly, this paper uses a sliding mode controller that can simultaneously create asymptotic convergence and deal with perturbations. The main problems controlling the slip mode can be considered asymptotic convergence, umbrella phenomenon, stimulus saturation, control gain estimation and failure to deal with time-varying uncertainties. In this paper, the terminal slip mode controller is used to deal with the phenomenon of asymptotic convergence and umbrella and the barrier function is used to overcome the uncertainties of time variable. The advantages of the proposed method include the elimination of the Chattering phenomenon, convergence in finite time, compatibility with time-varying uncertainties, no use of estimates and no need for information on the high limit of perturbations. Stability analysis shows that in the proposed controller, the tracking errors approach the convergence region in the zero range and provide faster convergence. Finally, to prove the efficiency of the controller, based on the chaos synchronization theory, we apply the proposed controller to a new 5D hyperchaotic system. The results show that the proposed controller, despite the disturbances applied to the system, provides rapid convergence and eliminates the umbrella phenomenon.

The purpose of this study is to design a model for the country of origin effect on the consumer's purchase intention in the home appliance market. This research was conducted by the qualitative method, an exploratory approach, and using the Grounded theory. The statistical population was the activists and experts in the field of home appliances; 11 people were selected for interview by snowball method. Finally, six selected codes were extracted by using open, axial, and selective 6-dimensional coding by the Strauss and Corbin method. These selected codes include Causal factors, pivotal factors, strategies, underlying factors, intervening factors, and consequences. After identifying that category and the relationships between them, the model of the effect of the country of origin on the consumer's purchase intention was designed. The results of the present study show that cognitive and normative dimensions of the causal factors affect the emergence of the effect of the country of origin, each of those dimensions includes several concepts. Through data analysis, we also discovered strategies and actions that are categorized in two sub-categories: producer-related actions and government-related actions. The consequences of the application of strategies are divided into two categories: micro-level and macro-level consequences.

The purpose of the present study was to investigate the impact of dynamic capabilities on the firm performance through the mediating role of business model innovation and sustainable competitive advantage, and the role of moderating environmental dynamics.

This research is applied in terms of purpose and descriptive-survey in terms of data collection. The statistical population of the study is companies located in of Tehran province.
