Information Systems Success: the Quest for Dependent Variable

Dependent variables are needed to be well defined in the IS success examination. Prior research more concerns on independent variables than the dependent variable. Instead, this article focuses on the measurement of the dependent variable. Shannon and Weaver (1949) and Mason (1978) yield six distinct categories or aspects of information systems success, which are system quality, information quality, use, user satisfaction, individual impact, and organizational impact. According to 100 empirical studies from seven publications within seven years (from 1981 to 1988), the user satisfaction appears the most widely used single measure of IS success. The most reason for the appeal of satisfaction as a success measure is that the most of the other measures are weak. Wixom and Todd (2005)…

Homework: Coding

1. How do modules help you to reuse code in a program? If a operation needs to be performed in several places, the same module can be called and re-used cutting down on unnecessary code. 2. Name and describe the two parts that a module definition has in most languages. The two parts are a header and a body 3. When a module is executing, what happens when the end of the module is reached? It jumps back to the part of the program that called it. This is known as the return point 4. What is a local variable? What statements are able to access a local variable? A local variable is declared inside a module and cannot be…

Marketing Research Report

Irresponsible human behaviours are impacting the environment. Therefore, environmental concern groups and also the governments around the world are trying to do something hoping to change people’s attitude towards environmentally friendly issues. This report aims at predicting the factors that motivate consumers to engage in environmentally friendly purchase behaviours. Convenience sampling of non-probability techniques was used to collect data. The data collected was then analysed by regression analysis, t-test and ANOVA. It was found out that political and technological factors have a positive relationship with environmental concern while success or anthropocentric have a negative relationship with environmental concern. Furthermore, environmental concern has a positive relationship with direct and indirect environmentally friendly behaviour and willingness to pay for environmentally friendly purchase…

Associate Level Material

Read the directions carefully and write JavaScript® code that addresses the requirements. Copy your code directly into this appendix document and post your assignment. 1. Write JavaScript® code that anticipates and handles an error for an expected numeric field. This code is executed on keypress, and the entered value is saved for you in a variable called enteredChar. Include the try block of JavaScript® statements needed to check if the character is not a number or a nonalphanumeric character, or if you throw an error message. 2. Write a custom error handling JavaScript® function called processErrors that handles a custom error by assigning it to the onerror event handler. Include the block of JavaScript® statements needed to pass the arguments…

Economies of scale and diminishing returns

In Business Economics, the short run is defined as the concept that within a certain period of time, in the future, at least one input is fixed while others are variable and the long run is defined as a period of time in which all factors of production and costs are variable. The law of diminishing returns is a short run concept, which states that increasing successive units of a variable factor to a fixed factor will increase output but eventually the addition to output will start to slow down and would eventually become negative. This is because if capital is fixed, extra labour will eventually get in each other’s way as they attempt to increase production. E.g. think about…

Best Ways to Analyze Data in Order to Improve Decision-Making

Descriptive Analysis: Defined as quantitatively describing the main features of a collection of information. Descriptive analysis are distinguished from inferential analysis (or inductive analysis), in that descriptive analysis aim to summarize a sample, rather than use the data to learn about the population that the sample of data is thought to represent. Two types of descriptive measures are: 1. Measures of central tendency: used to report a single piece of information that describes the most typical response to a question. 2. Measures of variability: used to reveal the typical difference between the values in a set of values. Two types of descriptive analysis are: 1. Univariate analysis: Univariate analysis involves describing the distribution of a single variable, including its central…

Using Global Variables

Global variables are variables that are visible to every module in the program and its scope is the entire program so that all of the modules within the program can access a global variable. They can be declared in modules by simply setting up an assignment box and adding in the variables to the modules. In Pseudocode, you will simply write out the particular variable you want to declare and its value. Many programmers go against the idea of using global variables in modules but there are a few good sides to using global variables. For one, the global variables are very easy to find within modules and can be accessed throughout all of them. Global variables also make it…
