Abstract

This paper aims at establishing the validity of Dr. Stephen Flynn’s recommendation for resilience in the event of a tragedy. Terrorism, particularly the September 11 attacks, and other adverse events have occurred in the United States over the past two decades, thereby prompting the need for proper planning for future events. The government does not carry the entire responsibility of developing national resilience; rather, every member of the community has a role to play. There is an urgent need for a continuous national willingness to advance robustness in order to lessen the risk of a discernible hazard, a ...

Introduction

The process of learning in animals and humans come through a series of situations that come together to motivate, and ignite the brains and enable them to repeat specific actions in the face of certain circumstances. The basic logic presented by psychologists and biologists is that there is intrinsic motivation based on the brain which controls the nerves and models of an animal or human being. This implies that an external variable triggers an extrinsic motivation that gets the organism to ignite the internal or intrinsic motivation in order to undertake certain actions and internalize it in order to ...

Identify different users of accounting information and discuss the varying information needs of these users.

Users of accounting information are both - internal & external to the company in question. Internal users are the primary users of accounting information.

Abstract.

Supervisory Control and Data Acquisition systems (SCADA) are a subset of Industrial Control Systems (ICS), and they are used to automate the control and monitoring of processes and sets of processes. Such processes include industrial production lines, power grids, rail switching and other critical infrastructure. Traditionally, these systems were isolated and thus secure from cyber-attacks. However, modernization has led to increased complexity, interconnectivity, and digitization. In this regard, today's SCADA systems need to communicate and transfer data from one site to another via communication networks that are at times public e.g. The internet. This development has created security vulnerabilities for ...

Article Review on Financial Econometrics

Cambridge University Article Review on Financial Econometrics For the article review assignment, I have chosen the article ‘Inflation and Real Stock Returns Revisited’ by Shu-Chin Lin, published in the refereed journal Economic Inquiry in 2009. The article addresses the topic of relationship between real stock returns and inflation, aiming to obtain the empirical evidence of the effect of different dimensions of inflation (including anticipated inflation, unexpected inflation, and inflation uncertainty) on the real stock returns. The motivation for the study arises from the inconsistencies between the generalized Fisher hypothesis and the empirical findings of the previous ...

There are seven phases in the structure of the Performance Uncertainty Management Process (PUMP) framework. They are: (a) defining the project;(b) focusing on the uncertainty management process; (c) identify all the relevant sources of uncertainty, such as, responses options and conditions; (d) structure of the uncertainty; (e) clarifying ownership; (f) quantify some uncertainty; and (g) evaluating all the relevant implication. Defining of the project helps in providing the effective common understanding of the project. In simple term, it helps to bring the whole team at the same page. The new members joining the team are able to come to ...

Information Systems, IT and Organization Culture

Organizational culture is a way of behavior, living, interaction and overall conduct of people in an organization. Culture is fundamentally the collective development and understanding of human minds that differentiate the members of a human group in relation to others; therefore, culture can be defined as a system of communally held values . Schien describes organizational culture to be the deeper point of basic conjectures and values that are fundamentally shared by elements of any organization, that operate instinctively and defined in basic fashion the organization‘s view of its environment and its self. Quinn and Cameron state that organizational culture describe the ...

Literature Critique

The association between viewing television shows at an early age and decline in quality of attention span among children has found formidable support from cross-sectional research design. The research under review, however, takes into consideration the importance of conducting a longitudinal study on the subject matter via use of data involving the age of children at the time of exposure to television watching and subsequent effects in later age. Data on children at the time when they were aged one and three (with separate sample sets per age) and detection of subsequent attention span problem signs at age seven has found gauging ...

According to the authors, there are three main considerations that business units ought to be privy to concerning the ecology. In a sense, businesses must be fully incorporated into the basics of the ecology and must tailor their activities in tandem with the ecology. In this strain, the ecology is described as facilitative rather than appreciative. However, the main rider is the organization in question ought to recognise the trajectory and state of affairs in the ecology and so tailor its programs, even the most mundane in consonance with the strategy. The three limbs of strategy are productivity, robustness ...

Posttranslational Mechanisms Regulate the Mammalian Circadian Clock

The issue of interest in these three research topics is the Circadian Clock. The first article, ‘Posttranslational Mechanisms Regulate the Mammalian Circadian Clock’ examines the posttranslational regulation of this clock in the liver of a mouse. The study published in this article used the mPER1 and the mPER2 proteins, the BMAL1 and the CLOCK proteins to show their significance in the stabilization of phosphorylated mPER2 proteins by the mCRYs. This article shows the Circadian rhythms to be greatly influenced by the biological clocks in the mammalian bodies. The timing system in mammals for example, is shown to be organized in a ...
