This study seeks to examine (1) the impact of crisis timing strategies (stealing thunder and thunder) on responsibility and (2) explore the role of involvement in the crisis communication field. The experiment employees a between-subjects design and utilizes a fictitious crisis scenario to collect data from 300 participants. The results show that the use of stealing thunder to mitigate crisis damage is much more beneficial to organizations than thunder.

This article presents a contrastive analysis of conceptual metaphors (CMs) denoting the concept of “Life” in English and Vietnamese lyric songs. Based on the theoretical background of many linguists, especially Lakoff and Johnson (1980), Lee (2001), Kovêcses (2005, 2010), as well as the data collected from the questionnaire and interviews, the study investigates and explores the similarities and differences in CMs of “Life” between the two languages from the cognitive perspective.

The concept of trunking began with the telephone industry. • Multiple calls were moved between customers and central offices or between the offices themselves over a single physical connection.The same principle was applied to data communications to make better use of the communication line. • Additional advantages and cost savings were gained by using the same line for voice communications.The same principle of trunking is applied to network switching technologies. • A trunk is a physical and logical connection between two switches across which network traffic travels....

Introduction Data link control layer – often abbreviated simply to data link layer – is concerned with the transfer of data over a serial data link The transmission mode may be either asynchronous or synchronous and based on either a character-oriented or a bit-oriented transmission control protocol The data link layer is fundamental to the operation of all data communication applications

Data can be corrupted during transmission. For reliable communication, error must be detected and corrected are implemented either at the data link layer or the transport layer of the OSI model.Error detection uses the concept of redundancy, which means adding extra bits for detecting errors at the destination

Data and the Binary Code System ‘Data’, a plural noun, the term used to describe information which is storedand processed by is in computers. It is essential to know how such data are represented electronically before we can begin to understand how it can be communicated between computers, communication devices (e.g. facsimile machines) other data storage or devices. As a necessary introduction to the concept of ‘digital’ transmission, this chapter is devoted to a description of tha method of representing textual and numeric information which is called the ‘binary code’. ...

A data model is an integrated collection of concepts for describing and manipulating data, relationships between data, and constraints on the data in an organization. • A model is a representation of “real world” objects and events, and their associations. It is an abstraction that concentrates on the essential, inherent aspects of an organization and ignores accidental properties. • A data model must provide the basic concepts and notations that will allow database designers and end-users unambiguously and accurately to communicate their understanding of the organizational data....

This application note introduces the concepts of digital modulation used in many communications systems today. Emphasis is placed on explaining the tradeoffs that are made to optimize efficiencies in system design. Most communications systems fall into one of three categories: bandwidth efficient, power efficient, or cost efficient. Bandwidth efficiency describes the ability of a modulation scheme to accommodate data within a limited bandwidth. Power efficiency describes the ability of the system to reliably send information at the lowest practical power level.

GSM (Global System for Mobile Communications, originally Groupe Spécial Mobile), is a standard set developed by the European Telecommunications Standards Institute (ETSI) to describe technologies for second generation (2G) digital cellular networks. Developed as a replacement for first generation (1G) analog cellular networks, the GSM standard originally described a digital, circuit switched network optimized for full duplex voice telephony.
