MNEs employ a global strategy to achieve growth, whereas their subsidiaries use a local strategy to operate effectively in host countries. Corporate social responsibility (CSR) is an effective strategy adopted by MNEs to develop a legitimate image in host countries. In fact, stakeholders' concerns in different countries and industries should be attended by MNEs and their subsidiaries. MNEs use social media to communicate with stakeholders and disclose their CSR activities. This study highlighted the importance of this context. In other words, stakeholders in different countries and industries react totally differently to Twitter posts. Therefore, MNEs should not communicate and interact with... 

For both Fichte and Hegel, self-consciousness is an intersubjective concept; that is, for them, self-consciousness is necessarily constituted between, at least, two subjects. In Foundations of Natural Right, Fichte introduces summons and recognition as necessary conditions of self-consciousness, without which, i.e. an other who is calling upon the subject, the subject cannot be conscious at all. Hegel, in Phenomenology of Spirit, also says self-consciousness is desire which is satisfied only in another (self-) consciousness. Based on these ideas, I try to show that self-consciousness can be defined as having the both in view; the self (I) and the other (not-I), at the same time. In this... 

According to official statistics, family businesses form the majority of businesses around the world. When we talk about businesses, we are more likely to say that those firms face issues related to family businesses.One of the trending topics that has recently been considered by researchers and a lot of research has been done in this regard, is specific issues related to marketing and branding of family businesses.In this study, we tried to examine the family business brand in terms of reputation. Reputation is the perception in the minds of brand stakeholders about the brand and the organization. So we tried to take as fair and accurate a sample as possible, to seek the opinions of... 

The concept of "experience" plays a key role in modern philosophy. Experience is also the central concept of Adorno's philosophy. Adorno's claim is that the possibility of human experience in contemporary western society is facing limitations. From Adorno's point of view, experience has become objectified in the contemporary western world. Such a situation distorts the relationship between the subject and the object and distorts the experience. While describing the experience in the contemporary world, Adorno explains the conditions for the possibility of undistorted experience. According to Adorno, objectified relationships are reproduced in philosophical theories. Therefore, he seeks to... 

The extant body of literature provides limited coverage regarding the concurrent influence of social responsibility and brand authenticity on both brand expression and adverse consumer behavior. Insufficient attention has been devoted to the correlation between social responsibility and brand forgiveness, as well as mischaracterizations of branding. The interplay of brand and consumer ethnocentrism further serves as a moderating factor in the associations among social responsibility, brand forgiveness, negative discourse, and brand avoidance. Four distinct scenarios, involving the random allocation among distributed companies, were considered: 1. Authentic brand with the presence of social... 

The main need in material related design is the true knowledge about the material properties. Existence of the cracks in the structure of materials is one of the main sources of weakness in the materials. Experimental evidences confirm that the surfaces of the cracks are mainly irregular, but in the existing theories in fracture mechanics all of the results are derived through the assumption of mathematical crack with smooth surfaces or at best with simple geometrical shape. In recent years, after it is being confirmed by experimental results that the fracture surfaces are fractals, several researchers tried to investigate the effect of the roughness of the fracture surfaces in the relations... 

In elliptic curves equation, if the number of solution is infinite, complication of calculation increase quickly. Even the simplest solutioncan be large. y2 + y = x35115523309x − 140826120488927 The x-coordinate number of smallest solution has 5454 digits. The theorem of Mordell and Weil states that “The set E(Q) of rational solutions has the structure of an infinitely generated abelian group.” E(Q) = (Z)rankE(Q) ⊕T Can the rank be arbitrary large? The current record is rank(E)=28.Manjul Behargava has recently made progress on the study of the average rank for all elliptic curves with rational coefficient. Every such curve has a unique equation of the form y2 = x3 +Ax+B, where A and B are... 

In this thesis, we deal with the problem of direction of arrival (DOA) using single-snapshot samples taken from multiple source signals by an array of sensors. The array we are looking for in this work is a uniform linear array. There are many ways to solve this problem, including MUSIC and Prony. But one of the few methods that are able to estimate correctly with single-snapshot samples with incomplete uniform linear arrays in compressed sensing base algorithms. In the first step, we can estimate the data of a incomplete uniform linear array by arranging them in the form of low-rank Hankel matrices and using leverage scores and minimizing the weight nuclear norm. If the weight matrices are... 

Most used polymers, such as hydrolyzed polyacrylamide, are not able to withstand high levels of salinity and high temperature of the reservoirs. To overcome these problems, in this project, new types of microstructures based on modified acrylamide with hydrophilic groups (malic anhydride monomer) and hydrophobic groups (styrene monomer) using inversible mini-emulsion were synthesized. The structure of the synthesized terpolymer was investigated using methods of FT-IR and 1H NMR. The micro-structure and the particle-size of the terpolymer particles were studied with the scanning electron microscopy (FE-SEM) and differential light scattering (DLS) method and the results showed that the average... 

There's a significant growth in sustainability reporting among top companies around the world in which based on KPMG report in 2017, 93 percent of 250 world's top companies have released their annual report in this field and this much attention to the reporting is a sign of special importance for and emphasizes on the necessity of corporate social responsibility in organizations. Since before doing the thesis there was no official statistics of sustainability reporting among Iranian companies, the research gap has been determined and by studying 100 Iranian top companies based on Industrial Management Institute ranking in 2017, we understood only 6 percent of these companies have already... 

Increased globalization and level of complexity of supply chains have made them more vulnerable to environmental disruptions than ever before. However, conventional methods of risk management can not help supply chains in the face of turmoil and disruption, because of unexpected and unfortunate events due to the unpredictability and uncertainty in which they are. They can have irreversible effects on supply chains and even threaten the very existence of members of these chains. In such a situation, the key to the success and survival of supply chain operations is to achieve supply chain resilience. On the other hand, health care supply chains are one of the most important and vital parts of... 

In competitive markets where a product or service is provided by multiple providers, as the telecom market, keeping active users is expected to be less expensive than attracting new users. In this regard, first of all, churning should be predicted for active users, and secondly, proper recommendations should be provided to prevent churning. In this thesis, by modeling customer churn as a response to the recommendations, we study the churn prediction and prevention problem as a recommender system. This model enables us to select the best offer for each user to prevent it from churning.Modeling customer churn in a recommender system introduces new challenges, including delay in observing... 

Organizations now take several risks and many factors affect their anticipated performance. The origins of these risk could be external such as Interest rate, political and social changes and change in governing laws and regulations or could be internal such as operational risk, information risks and strategic risks. Enterprise risk management (ERM) as a holistic approach to risk management has been recently used by most organizations. Prior researches on ERM efficiency have inconsistent results and there is a need for more meticulous scrutiny. In this research we examine the role of corporate social responsibility (CSR) as a mediator in the relation between ERM implementation and firm’s... 

Brain states analysis during consciousness is emerging research in brain-computer interface(BCI). Emotion recognition can be applied to learn brain states and stages of neural activities. Therefore, emotion recognition is crucial to the analysis of brain functioning. Electrical signals such as electroencephalogram (EEG), electrocardiogram (ECG) and functional magnetic resonance imaging(fMRI) are frequently used in emotion recognition researches. Convenience in recording, non-invasive nature and high temporal resolution are the factors that have made EEG popular in brain researches. EEG can be used to identify brain region activity solely or the connectivity of various regions in time in the...

Nowadays, customers hold a pivotal role as co-creators of value in service industries. Therefore, companies usually try to encourage customers to interact and co-create value effectively with the company or with each other. However, if a service provider fails to meet customer expectations, service failure occurs and may influence customer evaluations to co-create value. In this situation, companies usually try to redress the problem that happened to reduce their negative perceptions. Research related to the drivers of customers' value co-creation intentions has gained interest in recent years. However, there has not been an integrated view to simultaneously examine the negative role of...

Like other industries and research literature, tourism and hospitality have increasingly interpreted and analyzed the vast amount of user-generated content and online reviews to address practical and theoretical issues concerning customer experience and satisfaction. One of the most underdeveloped data-driven research streams in tourism and hospitality is green restaurant research. To address the gap regarding the actual behaviors, perceptions, and anticipations of such restaurants' customers, this study first used a new advanced topic modeling algorithm to identify hidden topics of customer reviews. The result suggests that customers mostly perceive food-related green attributes when it...
