Social Networking and Its Effects on Interpersonal Communication

...2013). An aspect of social media that is a current phenomenon in modern society is social networking, which consists of both mobile communication and web-based communication with Internet users through websites such as Facebook, Twitter, MySpace, YouTube and LinkedIn. These social networking websites have introduced a revolutionary means of communication that was not present in past decades. Interpersonal communication is defined as what one uses with both spoken and written words as the basis to form and maintain personal relationships with others (Heil, 2010). It focuses on investigating the interactions between individuals, which take the form of dyadic relationships as well as individuals within a social network. Some communication scholars consider the term interpersonal communication to be synonymous with interpersonal communication (Huo, 2011). With that, our interpersonal communication characteristics often determine how we communicate online (Palmer, 1995) and “the fact that most users create a sense of humanization in their emails makes their communication more interpersonal in nature” (Swats & Walther, 1995). In this modern society people can no longer consider the social media phenomenon as a "new thing" (Tardanico, 2012). Social networking websites have been widely used and growing in popularly for a long enough period of time now where entire generations of people use their tools as essential means of communications. Still, the significance of interpersonal...

Modern Managerial Myths

...Seminar 2: Modern Managerial Myths Introduction There have always been many myths surrounding management as a profession. During the 1800s, the manager was portrayed as a “foundry proprietor”, whose task was to build solidarity among the employees, and get everyone to “pull together” (Nilson & Åberg, 2007). This changed drastically during the 1900s, and the industrialization came to require a completely new type of leader. A manager generally possessed a high degree of technical knowledge (ibid.). However, the tayloristic view of management was soon out rivaled by the “human relations movement”, thus once again requiring a new type of managers, now more focused on building interpersonal relationships with the employees (ibid.). At least, this is what the large plethora of management literature has taught us. Hill (2003) discusses what “it really means to manage”, questioning some of the classical myths surrounding the notion of management. Myths like the managers’ source of power (formal authority), focus (managing one-on-one) and essential competencies (technical) are contrasted with evidence from the reality. However, as mentioned by Hill (2003) in the preface, “increasing globalization and significant demographic changes in the workforce” has lead to drastic change, affecting both managerial myths as well as their reality. The aim of this paper is to discuss Hill’s (2003) managerial myths and reality (se exhibit V-2 “What It Really Means to Manage”, p. 268), and whether Hill’s...

In this modern day and age, society has created new means of communicating and interacting via the internet. Instant messaging, strangers and “friends”, likes and favorites; One has now entered the virtual world of social networking, where information and photos of anyone and everyone are available at one’s fingertips . Social media refers to the interaction among people via the internet in which they create and share information. Facebook, Twitter, Instagram, and Snapchat just a few networks that teenagers constantly check, update, and gossip about everyday. As a teenager myself, I experience the effects of social media first hand. A walk in the park with friends turns into a photo shoot for a new profile picture or a debate over what to tweet. Social Networking changes the way teens interact with each other and how they interact with society in general. Although it useful for communicating and sharing information, Social Media’s negative influences outweigh its positive influences. Silence at the dinner table, procrastinating on homework, and checking one’s phone instead of exercising are all negative effects of social media. People who use Social Media feel required to maintain their profiles and constantly check newsfeeds in order to stay up to date with what their friends are doing. Often times people won't...

Evaluate the Impact That Entrepreneurial Networks Will Have on the Novice Nascent Entrepreneur Setting Up Business for the First Time

...Evaluate the impact that Entrepreneurial Networks will have on the Novice Nascent Entrepreneur setting up Business for the first time Introduction The extent to which entrepreneurial networking has an impact on the nascent entrepreneur is an interesting hypothesis. There is evidence to suggest that the nascent entrepreneur is reliant on the use of networking, yet other evidence states that the success of this type of entrepreneur stems from contrary elements. "Entrepreneurial networks provide a framework for processes aiming at organising resources according to opportunities" (Johannisson & Monsted 1997, p109). This definition clearly states what the use of entrepreneurial networking sets out to do, and is supported by the assumption that networking is the "acquisition of entrepreneurial skills" (Martinez & Aldrich, 2011, p7). This report sets out to assess the impact of which entrepreneurial networking has on the nascent entrepreneur: "Individuals who are in the process of starting up new ventures" (Renko, 2012, p1045). In the following report, an investigation as to what classification of impact that entrepreneurial networking has on the entrepreneur will be assessed. Based on academic research, a definitive conclusion will be made and a judgement of the usefulness and level of impact these networks have will be assessed throughout. The report will take into account the difference between academic opinions, and note that many academics believe that entrepreneurial...

The fact that I am in the military, the use of social media is very important and dangerous at the same time. The potentialities of these platforms are enormous and their control, monitoring and use are a must. Modern social media networks are actively used by governments all around the world. US, China and Russia are the countries that are most active in this field, but authorities from Iran and Syria have also demonstrated some interest for different purposes. Using social media militias could enable a cyber-offensive act against foreign governments. Let’s say, for example, a cyber-espionage campaign for the diffusion of specific crafted malware, but with powerful social platforms, this could also be used to influence the global sentiment of a population in countries feeding such dissent against the central authorities. It is inevitable to ignore the fact that nowadays social network plays an essential role in people’ lives. Most youths are spending at least an hour in these popular social media sites.

...connected with his/her dear ones? The answer is to create a profile on social networking sites (SNS) like Myspace or Facebook, connect with the friends, and start sharing your thoughts and memorable moments of life by uploading the pictures or videos at your leisure. Post 1999, online social network sites like Myspace and Facebook have become common destinations for young people in the United States. Throughout the country, young people were logging in, creating elaborate profiles, publicly articulating their relationships with other participants, and writing extensive comments back and forth. Participation on the key social network site, Myspace, is essential to being seen as cool at school. Michael Duffy, an editor at TIME, coined FaceBook.com as – a noun and a verb (Duffy 2). This is because teens often refer SNS in context with the phone call or text message for instance a daughter replied her mom that she’d “Facebook” someone for the assignment (Duffy 1). While not all teens are members of social network sites, these sites have developed a significant cultural resonance amongst American teens in a short period of time. The luster created by these sites has infatuated teens and has prevailed to be an important part of their social life. Facebook and Myspace have been two of the longest lasting fads in the internet world, and have truly made a name for them as a lasting presence for social networking, paving the way for sites such as...

...Oral Communication 2 Fluency in a Second Language 3 Presentation skills and time management 3 Skills considered of least importance 3 5. Recommendations 3 What transferable skills should students develop during their time at university? 1. Introduction Transferable skills can be described as ‘skills developed in one situation which can be transferred to another situation’ e.g. problem-solving, decision-making, or communication skills. These skills are also known as ‘soft skills’, ‘key skills’ or ‘generic skills’ and are essential in all areas of life, not just in learning or work situations. In recent years Higher Education institutions have begun to identify particular transferable skills they wish their own graduates to develop during their time in third-level education. However, an essential part of identifying important skills for students to develop is to seek the opinions of students themselves. The focus of this HEA-funded project is on modern language students. Hence this survey was conducted with this student cohort only, rather than with a cross-section of the student body. Most surveys undertaken to ascertain students’ opinions on the important transferable skills for them to develop, have been surveys of diverse student populations. It is interesting to note that the results of these surveys have been quite similar across different student groups. By far the most common skills that have been identified by students as being important for their careers have been...
