This paper will describe the chosen crime scene scenario, describe the collected evidence and proper collection, recording of the evidence, chain of evidence, processing, interpretation methods, preservation of the evidence, proper presentation methods for different types of evidence, and the consequences of mishandling the evidence collected.
The Crime and Processing Protocols
The chosen crime scene scenario is a sexual assault; the first responding officer will have been notified of a possible rape and traveled to an apartment complex at 306 Timber Road, Apartment 12-B to investigate. Upon arrival, the first crime scene procedure is to make sure the crime scene is safe and the possible offender has been arrested or is no longer on the scene. If the struggle were still occurring, this would be the point to render aid. The next procedure would be to determine the extent of the crime and to secure the scene from intrusion to preserve any evidence. It is important for the responding officer to keep their superiors informed of their activities. At this point the responding officer will touch nothing and document all of their observations and actions, if the scene had been disturbed in any way while rendering aid, they should make note of this (National Institute of Justice, n.d.). In most cases the responding officer would wait for the investigating officer and crime scene crew to arrive to process the scene. (Osterburg & Ward, 2010).
Types of Evidence While speaking to the victim, the officer must be sure a crime has really been committed and to get the facts: when, where,

In order to address the differences in learning abilities teachers find themselves using the term streaming. There are a number of definitions of streaming. To begin with the Oxford English dictionary defines streaming as the policy of dividing school students into groups of the same level of ability. Daniel Muijs (2011), also defines streaming as a procedure where by students are segregated into different classes according to ability within their school. Likewise, in it has been elucidated that streaming or ‘’tracking’’ means that students are placed into groups defined by their ability levels. Streaming policy has been a bone of contention among teachers and policy makers for many years. Carole Faithorn (2003) lists some of the...

...Accounting Information Systems ACC 210 August 30, 2012 Michael Wells FedEx Corporation is one of the leading logistics service companies in the world. As its global presence increases and technology becomes more accessible and powerful, FedEx must stay ahead of the curve to keep customers satisfied, and competitors on their toes. In the past 10 years FedEx has made much progress in automating many of their information systems such as invoicing and accounts receivable. They also led the industry in providing online services to their customers, and high-speed mobile devices to their couriers. One of their most notable technological advances was their development of DirectLink. FedEx created DirectLink, a powerful electronic data interchange (EDI) enabling software, to allow customers to download invoices, create reports, export data, and remit payments. Customers can still pay their bills online, over the phone or the traditional way by mailing in payments; however, FedEx encourages customers to sign up for DirectLink because of many advantages it offers (FedEx, n.d.a). DirectLink allows customers to download bills, remit payments online and manage their own account, which is extremely efficient for the customers and the company. For one, electronic invoicing allows FedEx to save money on printing and postage costs. Electronic payments also save time and create less manual work for the company. The AIS validates records and processes payments. With...

...advantage of a system that has taken many years and billions of dollars to develop. It all starts with the package labeling. For each package a label is given. On the label are a barcode and a number. On the barcode UPS inputs important information about the sender, destination, and estimated arrival time. UPS uses this information to process its packages. With its automated tracking system UPS can monitor the delivery process and even re-route packages if needed. Periodically through the life cycle of a delivery barcode devices scan shipping information on the package labels to update milestones in the delivery status. Customer reps can use this information to update customers on where their package is. Customers also have the option to check themselves vi a the UPS website or mobile app. UPS utilizes a myriad of technology to insure its success. One of the most important is its Delivery Information Acquisition Device (DIAD). This is the everyday device that uploads to a wireless network and gives its drivers instructions for the day. It also captures customers’ signatures and automatically updates tracking information in the UPS system for processing and storage. From the beginning UPS promised “the best service and the lowest rate.” UPS works hard to deliver on this commitment. Going back to UPS’s label system information is sent to one of its computer centers before the package is even picked up. This information is used by dispatchers with special software to create the...

...[March 5th, 2010] [pic] | Rebecca Murphy, Reginald Demery and Melanie Bennett | Kudler Fine Foods is a small franchise of three stores currently. Each store provides the quality of service you would expect from a specialty store. Even though small in size the product selection is large. The current operating system each store has needs to be upgraded. All stores should run the same equipment requirements and software. Initially there would be cost involved for the upgrade but it is definitely a well worth investment to improve sales inside the stores and online. Adding the feature of ordering online would boost sales. Kathy Kudler would be able to create this online ordering site from within the current site or she could bring someone in to create it. Again it would be a well worth investment. Kudler Fine Foods is an amazing company but the website lacks information and customer satisfaction. When a customer visits the Kudler Fine Foods website we want them to experience the very best customer service while allowing them to want to revisit. We have to improve a lot of problems with the Kudler Fine Foods website to better help our customers and in order to do that we are going to improve the websites appearance, improve communication, which will include a 1-800 number for customers if they have a problem, create a FAQ page/email and most importantly...

Automated Inventory System

...Plan for Automating an Inventory System Tiffany N. Sommers Strayer University (Winter 2016) Instructor: Dr. Stephen Huber Plan for Automating an Inventory System During a conversation at the dinner table, I learned my sisters frustration with having to manually track and reorder high demand items. She wants to upgrade to an automated system using a small budget. Making a plan that fits her budget in this economy is going to be tough but is very manageable. If you look at businesses in the market, then one should know that a business should be able to adapt to change and provide a service that is fast and reliable. We are going to be taking my sisters manual tracking and ordering system to an updated automated system. In order to make her store automated we will have to go on a shopping spree and purchase the hardware for the automated inventory system. Since we are on a budget we will look at the main things that will be needed. Hardware is a major part of automating her business. Hardware consist of a computer or laptop, an operating system, keyboard, router, mouse, and external hardware (i.e. printer, fax, and copier). My assumption is that she does not have any of this so we are starting from scratch. After purchasing and setting up the hardware she will need we will move on to the next step, Software upgrades and requirements. Software can be simple or it can be complicated. It can also be costly if you are not careful. If we go with the more expensive route...
