Embedded Journalism and War Reporting

...Embedded Journalism and War Reporting Dion E Jones University of Phoenix COMM 220 Maureen, Duffy M.A. May 13, 2012 Embedded Journalism and War Reporting Journalism covers the principles of reporting in different circumstances such as the time-based news as in press conferences or untimely news of crisis, disasters and conflicts. Even though the reporting objectives are vast, and the journalists are expected to perform their duties without any fear or bias, it is the responsibility of the journalists to observe certain ethical considerations. At times, what journalists consider their responsibility may prove to be harmful for others. The policy of embedded journalism is debated mainly because, it compromises the military’s safety, security and strategy, through its bias and unethical reports; the presence of embedded journalists should not be allowed alongside fighting forces. Ethics of Journalism and War Reporting The question whether something is ethical or not, is gaining worldwide scrutiny these days. With the advent of social media, people have access to so much detail regarding the circumstances of the world. The journalists who are active through social media seem to provide all the minor details to their followers notwithstanding the ethical aspect of such information. The line between what...

Security Exploitations of an Rtos

...Systems in Embedded Systems Welton N. Spratley Southern New Hampshire University Running head: SECURITY EXPLOITATIONS OF REAL TIME OPERATING SYSTEMS 2 Security Exploitations of Real Time Operating Systems in Embedded Systems Abstract: Real Time Operating Systems that are currently used in embedded systems around the global community has seen an increase in the number of devices that are being employed using this technology. With the implementation of IPv6 , the number of IP addresses that are now available in order to support this boom in the use of embedded systems have also seen an increase in the types of operating systems that helps to manage these systems. However, this has created another area where malicious attackers can exploit some of the security flaws that can be found in these embedded systems. This research paper will outline how microkernels and monolithic kernels that are found in these real time operating systems have been exploited due to careless source code programming in their stack and heap memory areas. Some of these flaws can lead to buffer overflow of memory core areas which can lead to memory being overwritten and being replaced with other I/O or buffer underflow of memory which can lead to memory leakage. Disaster happens when an operating system fails to prevent the unauthorized usage of resources in relation to embedded systems.

 Tracking the Economic Value of the Embedded Technology

...* Tracking the economic value of the embedded technology: Future outlook and trends: The Embedded Digital Technology use in our everyday life is highly significant. To some estimate, around 98% of all the programmable digital devices are in some way embedded which includes the digital devices which embedded under the humans skin. Both current and future studies and trends suggests to a dramatic potential for a much bigger growth. All the future outlooks of this technology points to a much wider use based on both enhanced functionality and cost reduction. “There are now more embedded devices than people on earth. As chips and wireless communications become universal and inexpensive, an enormous potential is created for new applications and novel ways to support our society and people’s lives” said Viviane Reding The former European Commissioner for the Directorate General Information Society & Media. This study by author Geomina Turlia and conducted with the support of European Commission, focused on the inter-linked between macro and micro approach to the technology so it can support the importance of the proposed overall methodology when looking into the economic value of the embedded devices in general. However, it is as important for implementation purposes to also use other supported tools like using a European National Accounts Data so finding the correct economic value can be refined specifically when more needed sectorial or thematic studies can be further......

Embedded Journalism

...Embedded Journalism COM: 235 Final Research Paper April 24, 2014 Chloe Di-Tommaso Dr. Meade “Embedded Journalism” Throughout our studies amongst media law and ethics, I have grown particularly absorbed by the weights and balances of embedded journalism within our war culture today. My research aims to evaluate both the values and drawbacks of the Pentagon’s decision to pursue embedded journalism during the war on terror in 2003. I will be offering an in-depth evaluation of the history, objectives and purposes of embedding, how embedding raises concerns with the First Amendment’s entitlements, and finally questioning the notion that embedded journalism decreases censorship and increases access. In order to understand the current iteration of embedded journalism, we must understand our nations history of war correspondents and their relations with soldiers (Mayfield, 2013). The history between the military and the media lays the foundation for embedded journalism and serves as a reminder that the absence of censorship in past wars provided the impact on todays embedded program into Iraq (Brandenburg, 2007). Military-media relations have been building up over time, it originated with the earliest correspondents in 1850 and today expands through British, French, and American military engagement with the media (Mayfield, 2013). It wasn’t until the second half of the twentieth century that America began utilizing their media to report on current warfare’s. However,......

If it is not, then the security has more characteristics of equity. FAS paragraph 150-9, A mandatorily redeemable financial instrument shall be classified as a liability unless the redemption is required to occur only upon the liquidation or termination of the reporting entity. A financial instrument issued in the form of shares is mandatorily redeemable if it embodies an unconditional obligation requiring the issuer to redeem the instrument by transferring its assets at a specified or determinable date (or dates) or upon an event certain to occur. In this case, the issued shares are not mandatorily redeemable, they are conditionally redeemable. Therefore, this provision is not applicable. Analysis of the embedded derivatives: Redemption feature If the security is contingently redeemable, the contingent feature might be an embedded derivative as......

Knowledge Management Embedded in Social Media – Successful Company and Its Innovations

...Knowledge management embedded in social media – successful company and its innovations ABSTRACT The continuous market pressures and competitions pushes the organisation to be in the race of making innovations besides safeguarding the talent and information they own. The race for new products and services for the customers arises due to increasing awareness and exposure through social media. This essay focuses on studying the knowledge management jointly with social media leading to innovation. The essay seeks to examine the role of social media taking IKEA as the case of interest. It aims to further investigate how knowledge management through social media help a company in its innovations, product development and services. 1. INTRODUCTION. Knowledge management has become the buzzword in recent past in the industrial sector. Companies have become very focused on the knowledge assets that they own and the capabilities of their organisation or company and staff to utilize theses assets. Thus, knowledge can be called a resource which could be acquired, exploited and applied to achieve success and advantage for the company (Zack, 2003). However, companies that fail to manage the knowledge it has might surely be losing its capabilities, potential and brains (Denford, J. S., & Chan, Y. E., 2011). The benefits that knowledge management offers ranges from promotion and elevation of unequivocal knowledge to attain efficiency and innovation in various business practices......

Embedded 3d Barcodes to Ensure Pills Are Real

...Another sort of scanner tag could be basically incorporated with a pill or other item, as opposed to simply slapped on the bundling. A group of specialists revealed the new innovation this week at the British Science Festival in Bradford, UK. Scientists from the University of Bradford and Sofmat, a hostile to extortion innovation organization, added to a framework to add infinitesimal spaces to the surface of an item. Little sticks are set to diverse statures, every encoding a letter or digit. The pins can either be inserted in the mold an item is produced using or stamped on a short time later. The subsequent code is verging on imperceptible, and excessively modest, making it impossible to feel. Be that as it may, a speedy laser sweep could demonstrate an item’s inception, which the specialists say could track and check items to battle fakes. The yearly worldwide estimation of fake merchandise has been anticipated to be more than $1.5 trillion by the International Chamber of Commerce. Fake hardware are an issue, and fake prescription can be absolute risky, containing the wrong dosage or no dynamic fixing by any means. This is particularly an issue in the creating scene.

Embedded Systems Design

...Embedded Systems Design Scott DeCota Modern Operating Systems Embedded systems are all around us. They run the engine, brakes, seatbelt, airbag, and audio system in your car. They digitally encode your voice and construct a radio signal to send it from your cell phone to a base station. They control your microwave, dishwasher, and DVD player. They command robots on a factory floor, power generation in a plant, processes in a chemical plant, and the traffic lights in the city. Embedded operating systems are growing increasingly common in everyday appliances and other devices. These operating systems provide application interfaces for a wide range of different applications. The challenge for developers is to determine which operating system or programming language to use in a particular device or project, and how to utilize the parallelism and concurrency capabilities of the hardware and programming language chosen for a project to design a system of adequate timing precision and efficiency. Developers working with embedded systems need to be extremely diligent in regards to timing and optimization. Embedded systems are frequently interacting with the physical environment in which multiple sources of data may be interacting with the system simultaneously. Developers should have a solid understanding of the parallelism and concurrency capabilities of the hardware for a selected project. These features can occur in different forms that can greatly affect the timing of......
