...The Role of Cultures in Global Management Abstract What is culture and how other people deal with culture on a daily basis. Countries around the world work daily with different cultures in a business setting. There are many different ways that culture practices get done throughout the world.

...hundred years ago it would have taken these people months to communicate, but today they can communicate with the press of a button. As our interactions with those from cultures much different than our own increases, communicating with one another creates obstacles we normally wouldn’t face when interacting with those from our own culture. This presents the peculiar problem for the business because it must train managers to effectively communicate within the constructs of different cultural norms and values. Communicating to others the importance of diversity in multinational corporations is a difficult task because it essentially involves asking others to reject the idea of their culture being superior to others. As O’Rourke (2010) points out, “failures in an overseas business setting most frequently result from an inability to understand and adapt to foreign ways of thinking and acting, rather than from technical or professional incompetence,” (p. 284). Regardless of difficulty, if a business is going to remain competitive as a multinational corporation, it is absolutely imperative that managers successfully communicate with individuals from different cultures. I chose to research multi-cultural management strategies because I understand how multi-national corporations are growing in number and size. Understanding why some are more successful in the global marketplace than...

...The Role of Performance Management in Establishing and Maintaining Corporate Culture Performance management provides a large role in the establishment of a corporate culture and maintaining it, as well as observing the performance of the employees and provides the necessary positive and corrective feedback. “Performance management is considered the frame work of talent management, which encompasses all areas of HR that have to do with onboarding, developing, evaluating, and managing the workforce through all the normal cycles” (Kavanagh & Thite,2009, p. 341). This in turn is the connection that is developed between performance management and the company’s corporate culture, and it is dependent on the connection between management and employees. Performance management is connected with several other areas such as, recruiting, staffing, career management, etc., all which play a primary role in establishing and maintaining a company’s corporate culture. In order for an organization to maintain their culture they must find individuals that are willing and able to adapt to their culture as well as maintain and recruit other employees that can do the same. The Role of Compensation and Benefits in Establishing and Maintaining Corporate Culture Compensation plays an important role in establishing and maintaining a corporate culture. Compensation includes base pay, merit pay, short-term and long-term incentives. It also provides recognition awards, and the attraction/retention...

...Understanding, why change is frequently difficult for people, can help building in methods for easing the process and increasing the likelihood that it will succeed. Being very clear about what changes are required and being very intentional about building a culture, that supports the new mission, goals, strategies and practices, increases the probability of success exponentially. This necessarily involves a large cross section of the organization in assessing the current system of norms and beliefs, determining what changes are needed, and designing an implementation plan. These new beliefs and resulting behaviors needed to be elevated to a conscious level so that the company could choose how it needed to modify its practices. New assumptions and values should be articulated and systematically communicated through every channel and should be reinforced at every opportunity. It is true that changes in organizational culture are brought about through employees, so the employees play a major role. But role of the leader cannot be overruled because they influence the organizational culture very deeply. Culture is deep seated and difficult to change, but they can influence or manage an organization's culture. It isn't easy, and it cannot be done rapidly, but leaders can have an effect on culture. Productive cultural change will occur if leaders correctly analyze the organization's existing culture, and evaluate it against the cultural attributes needed to achieve strategic objectives...

However, I understand that my beliefs, views and biases can impact others throughout my practice and my cultural background can often lead others to have misconceived perception of my views and beliefs, due to my culture. I understand and accept that every culture has different ideologies, social structure and beliefs and through this understanding,...

...ELSEWHERE A DEVELOPMENT OF CONCEPTUAL FRAMEWORK FOR STUDYING COMMUNICATION COMPETENCIES AMONG DIRECT SELLERS IN MALAYSIA Many studies have been conducted related to communication competencies since the last decade until now. However, the availability of the studies on communication competencies has not been explored in depth particularly in the direct selling context in Malaysia. To understand the direct sellers’ communication competencies, a conceptual framework will be built based on related literature studies. Literature reviews have shown a variety of studies on communication competencies from the behavioral and cognitive perspectives. Although numerous studies have provide understanding of communication competence in various context, there is a gap in viewing communication competencies in a more dynamic context, particularly in the process of communication of direct sellers with their potential customers. This paper attempts to discuss the importance of a dynamic research related with communication competencies by developing a conceptual framework for a direct selling as a communication process. INTRODUCTION The key purpose of this paper work is to discuss the need of developing a conceptual framework for studying communication competencies of direct sellers in Malaysia. Research on...

...Sundaravalli Sri Venkateswara University, Tirupathi ABSTRACT: Cross-cultural communication has become ever more significant through the globalization of markets, affairs of nation-states and technologies. Consequently, the cultural quotient (CQ) is becoming increasingly important, especially in the context of the changing dynamics of work culture around the world. This paper makes a case for the need to pay attention to intercultural communication and discusses some specific approaches and strategies in the teaching of intercultural communication in the classroom. These approaches include addressing issues like learning to honour one’s own culture and sharing it with others while developing a capacity to be open to other cultures. Other strategies include progressing from an ethnocentric to an ethno-relative state of understanding and acceptance of cultural differences and increasing one’s ability to communicate with non-native speakers. Specifically, classroom practices and strategies suggested include intercultural explorations, use of texts, films, short stories and other multi-media resources, contrastive case studies of cultures, group encounters and role plays. Introduction Sir Francis Bacon said that if a man was gracious and courteous to strangers, it showed that he was a citizen of the world, and that his heart was no island cut off from other lands, but a continent that joined them. The present work force even in local contexts demands global skills such as excellent communication...

As such, this calls for specialists to be weary of how they perform their diagnosis since out of the diversity associated with certain cultures realized among varied people within any community, treatment associated with culture bound syndromes and symptoms are not clearly defined as they may seem to be.

This has been backed up by the unending dispute that is realized pertaining to the legality with which culture manifests...

...Culture and Socialization Learning to be Human Understanding Cause & Effect • Correlation - the existence of a regular relationship between two sets of occurrences or variables. • Causation - a relationship in which one event or situation brings about the other. • Correlation does not imply causation. But a causal relationship must mean that two variables are correlated. Sociological Imagination • The more we understand what is happening in the world, the more frustrated we often become, for our knowledge leads to feelings of powerlessness. We feel that we are living in a world in which the citizen has become a mere spectator or a forced actor, and that our personal experience is politically useless and our political will a minor illusion (Mills 1959) Macro argument. Chapter 3 Culture & Society The Concepts of Culture Culture - The values the members of a given group hold, the norms they follow, and the material goods they create. Values - abstract ideals. For example, monogamy is a prominent value in most Western societies. Norms - definite principles or rules people are expected to observe Society - a system of relationships that connects individuals who share the same culture. The Concepts of Culture Culture and society are closely related. Cultural variations among humans are linked to different types of society. No culture could exist without a society; equally, no society could exist without culture. The Concepts of Culture Ethnocentrism – judging...
