Explain how neuroscience research with humans and animals has advanced our understanding of the role of the amygdala in fear processing - Essay Example stifications for the fear/panic response is an evolutionary self-preservation mechanism with the obvious intent of preserving the organisms safety in situations of predation or other forms of physical danger. (Holt, 2008) the essentials of the mechanism that initiates the fear/panic response appears to be rooted in a signaling process directed towards the amygdala. This region upon receiving the signal appears to demonstrate a priority stimulus, by which the relative importance of a particular external phenomena is impressed into a neural cellular pattern that can trigger emotion – based responses. This would include the fight or flight mechanism, common to virtually all chordates, including humans. (Blanchard, 2008) as well as other emotional states that are responsible for the regulation of the appropriate endocrine functions that would permit the appropriate response, such as increased output in the adrenal glands for instance. Researchers have found over the years that while a particular unpleasant stimulus can trigger the fear response in the amygdala of humans and other mammals, there is also the possibility of a fear stimulus based simply on the threat of an event; through the mechanism of fear conditioning. The fear response has been studied in regards to the contributions of the human amygdala; which demonstrates involvement at all stages of fear/panic conditioning or phobia acquisition. (Delgado et al. 2006) Classical studies have warned human subjects that a particular color presentation will presage a mild electric shock to the wrist, and the reactions garnered from the subjects prove that in humans physiological conditioning to fear can be easily achieved, in a process called instruction acquisition. (Hugdahl & Ohman, 1977) Activity in the left amygdala could be measured using functional magnetic resonance imaging even though during the course of the study, none of the subjects actually received the mild electric shock to the wrist that they were

Identify the ethical issues within the field of Information Technology Essay

Identify the ethical issues within the field of Information Technology - Essay Example A number of ethical concerns are associated with implementing the proposed integration project. Firstly, Accounting software, Graphic design software, operating systems, and virus guards can be purchased from unauthorized venders at a lower price. This is an act of violating laws regarding copy right, patents and trade secret. In addition using low price software which closely resembles the originals is also unethical. Such software can be associated with plagiarism, reverse engineering, open source code and cybersquatting(Ethics in Information Technology - Auburn University). Secondly, employees are responsible for using firm’s computers, internet facility, software and other appliances solely for the purpose of fulfilling the duties assigned to them. This is important to increase firm’s productivity (431). Workers are also expected to avoid unauthorized using of firm’s computers and confidential data. Accounting firm’s administration cannot rely only on trust for security issues like this while in the process of integrating with a different firm. On the one hand employees of two firms adapt to changing organizational structure after a certain time period. Organizational disputes can happen during this time period (Schein, 2004 ). On the other hand newly established firm has a larger number of employees. Firms use low cost and convenient IT solutions to monitor and supervise a large number of employees. New computers that are provided under this project will be linked via a computer network system. This shared network system can be used to obtain high speed internet facility to all the computers in firm. There are unauthorized means of using shared internet connections. Ethical procedure is purchasing an appropriate package from an Internet Service Provider. Networking is also important for increasing resource use efficiency of the firm such as printers (314). In addition, accessing to websites such as Facebook, YouTube eBay and
