...(Q1) NDAS starts their long journey since 1985. Currently state of NDA office automation, system integration and networking differs from one department to another while some departments work manually. The payroll department currently carries out its own data processing using a mini computer. Due to expansion of the business and complexity of the billing process these processes are automated throughout Florida offices. The marketing and sales department which is headed by Bob Jones runs as a Local Area Network limited the sales and marketing division itself. This connects every personal computer of each account representative. When we come to Accounts receivable division which is headed by Jane Van Dyke, a powerful microcomputer server provides database for both customer billing and bad debts. The accounts payable division that is led by john Lawson functions with its own vender data base stored on an old minicomputer server. This data base holds billing details such as billings of ODI to NDAS and also this division is responsible for the payroll process. A LAN can be established as well since employees here also got PC’s on their desk similar to accounts receivable division. Peter Browne, the maintenance supervisor of the fleet maintenance division refuses to automate his division’s record keeping processes and satisfied with the usual way. Therefore this division has no computer capability. Fleet maintenance division has another part which is ‘Dispatch’. This......

HERZLINGER NATALIE KINDRED Shanghai Pharmaceuticals With 2011 revenues of $8.67 billion, 1 Shanghai Pharmaceuticals (SPH), a vertically integrated Chinese pharmaceutical conglomerate, produced active pharmaceutical ingredients (APIs), chemical and biological drugs, and traditional Chinese medicines (TCMs); distributed its own and other drug makers’ products to hospitals and other customers; and operated a chain of retail pharmacies. The company—essentially a collection of subsidiaries operating under a unified management structure— was formed through the 2009 merger of several state-owned enterprises (SOEs), part of a broad policy effort in China to streamline state assets, consolidate the fragmented pharmaceutical sector, and enhance the global competitiveness of domestic firms. Emblematic of China’s hybrid economic policies, SPH had both government and private shareholders and competed in a historically statecontrolled industry that was adapting to the growing influence of market forces. SPH’s initial public offering (IPO) on the Hong Kong Stock Exchange in 2011 marked an important step in its quest to transform from a traditional SOE into a market-oriented company. While working to expand SPH’s domestic footprint, the company’s leadership was also considering a potential acquisition of a U.S. or European drug producer, an unusual move for a Chinese company. SPH could leverage such an acquisition to learn from Western......

Begin by explaining how each department uses information technology, what hardware it uses, and what functions currently are automated. Also assess which department is most in need of a network. [5 marks] The level of automation varies significantly among the NDAS departments and offices. In addition, NDAS is in the process of downsizing to achieve a more cost-effective computer support system.

All of these computers are connected to a small local area network (LAN) that serves only the Sales and Marketing Division. The Accounts Receivable Division recently downsized its minicomputer to a powerful desktop computer with a faster processor, motor memory and increased disk storage space. This new desktop supports databases for both customer billing and “bad dept” expenses.

...beginning of a cumulative case study about a fictitious firm we call Next-Day Air Service (NDAS). The case study begins here in Chapter 1 and continues throughout the rest of the book. It requires you to complete tasks that are related to topics covered in each corresponding chapter of the text. The end of each chapter contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers. As with any real-life problem with ambiguities or unresolved considerations, you must make your own assumptions. Feel free to read ahead or use the index to find related subjects that support your recommendations. Your instructor may provide additional guidelines regarding report formats, Web and library resources, key assumptions, and the like for the various questions and problems presented in this case study. Be sure to provide adequate justification for any recommendations you make. (NDAS) was founded in 1985 to compete in the expanding market for overnight package deliveries. NDAS provides local pickup and delivery of these parcels and other small freight items. The founders initially restricted their efforts to the rapidly growing central Florida region. To support its operation, NDAS purchased a facility near the Tampa International Airport. This facility......

Clinical Trials for New Drugs. Therapies and Medical Equipment

...Clinical Trials for New drugs. Therapies and Medical equipment The process for a new drug can take years and several stages to be approved by the FDA (Food and Drug Administration). Although most drugs are tested for specific kinds of diseases they might often have disappointing results for a specific disease but may have great results for another. The FDA has twelve stages of drug development and Review; these are important procedures before and after clinical trials. The twelve stages of drug development fall into the FDA’s four categories: pre-clinical, clinical, NDA (New Drug Application) review and post marketing. In the pre-clinical category there are two stages; animals tested and IND (Investigational New Drug) Application. The drug sponsor, companies/research institutions responsible for developing a drug, develops a new drug and seeks to have it approved by the FDA. Once the drug has been developed the sponsor has to test the new drug on animals for levels of toxicity, safety and efficacy of the drug. The sponsor then must submit an IND application and must include the results from animal testing. When the FDA approves of the new drug they make sure that it is completely safe to proceed and test on humans. In most cases drugs that have gone through the pre-clinical testing never actually make it to the human testing phase or are reviewed by the FDA. If the new drug is approved for human testing the research moves on to the clinical category, aka......

Review

...Order Code RS22814 February 21, 2008 FDA Fast Track and Priority Review Programs Susan Thaul Specialist in Drug Safety and Effectiveness Domestic Social Policy Division Summary By statutory requirements and by regulation, guidance, and practice, the Food and Drug Administration (FDA) works with several overlapping yet distinct programs to get to market quickly new drug and biological products that address unmet needs. FDA most frequently uses three mechanisms for that purpose: Accelerated Approval, Fast Track, and Priority Review. The first two affect the development process before a sponsor submits a marketing application. Accelerated Approval allows surrogate endpoints in trials to demonstrate effectiveness and is relevant in fewer situations than the others. The Fast Track program encourages a sponsor to consult with FDA while developing a product. Unlike the others, Priority Review involves no discussions of study design or procedure; it relates only to an application’s place in the review queue. Analysis of total approval time for approved applications under the Fast Track and Priority Review programs shows that for seven of the past nine years, Fast Track products have shorter median approval times than do all those applications assigned to Priority Review. It takes an average of 15 years from the moment a manufacturer first approaches the Food and Drug Administration (FDA) with an idea for a new drug to its final approval for marketing.1......

Case Study: Sheila Mason and Craig Shepherd

...1. Evaluate the situation in which Mason and Shepherd find themselves with respect to their existing employers. What legal and ethical issues do you see and how would you advise them to proceed?     Mason's endeavor for the venture creation is strictly bounded by her employment agreement with ATS.  That is to say, she will be in clear violation of the Noncompetition, Nonsolicitation, Nondisclosure and Development provisions, if she plans to pursue the venture within one year by utilizing the information and social network she gained from the company.  So the first barrier she need to tackle is to prove this new business is not in competition with ATS at all. Also she cannot speak with any current customers of ATS. These limitations will probably strangle the venture in embryo. Also, Mason had recently played golf with a colleague, who told her that if she ever left the company or came upon an idea. he wanted to be involved. Yet, because she signed an employment agreement with a non-solicitation clause, she was very skeptical.  Another possible sticky situation is that ATS claims ownership of the data in her office computer, which contain many resources and information useful for her and accounts about her new venture. First aid for this situation is to remove all the incriminating data and information about the venture as soon as possible. Beyond that she can hire a legal consultant and lawyer to negotiate with ATM. Shepherd's problem is more about intellectual......

...of a network. NDAS was established in 1985. The main objective with NDAS is to compete in todays growing market for overnight package deliveries. The current state of automation varies among departments. Computers are linked to a LAN that only attends for Sales and Marketing. The Accounts Receivable Department, led by Jane Van Dyke, is accountable for all billing and collecting, as well as payroll.. The minicomputer that the company was using was recently replaced with a microcomputer server. An asset to this new server offers databases for bad debts and customer billing. The Fleet Maintenance, however, has no computer competence. The management in that department made a decision to track all the essential information manually. The remote offices currently communicate with corporate headquarters and each other via phone, fax, and mail. It is worth noting that there are desktop computers available in the remote offices, and a number of managers have laptop computers. Management realizes its need for regulating their systems, the equipment, and its procedures before any further networking can be proficient. The management also expect any of their systems to permit for development into other information technology areas of networking. 2. In view of the types of networks and future technologies discussed in this chapter, what kind of network would appear to be the most beneficial to NDAS? The network that would appear most beneficial to NDAS is to enter......

Ip Rights

...INTELLECTUAL PROPERTY RIGHTS What is an Intellectual Property? With compared to real property, Intellectual Property is NOT tangible because it is not a product of human skill but of human intellect. Therefore it is said that “it is a fruit of human intellect”. Why Intellectual Property Rights are important? Although it is a fact that the power of thinking or the Power of mind cannot be stolen by a powerful third party, it is equally true that “ Intellectual Property Rights “ are being violated all over the globe. Intellectual Property Law is the branch of Law that provides protection for this valuable result of human endeavor. In the process of the development of the world as it stands today, the human mind: the intellect played the major role which nobody can deny. Therefore every country has given a prominent place to this special branch of Law for the sake of economic development. What are the governing bodies and Acts of Intellectual Property Rights? Intellectual Property Act No.36 of 2003 is the frame work within which the Intellectual Property Rights are currently protected within SRI LANKA which is a member state of World Intellectual Property organization (WIPO) and a party for the International Treaties/Agreements such as (PCT) Patent Co-operation Treaty, TRIPS Agreement and Berne convention. The National Intellectual Property Office of Sri Lanka is the ONLY Government body established for the full control of IP related......
