1- An information security manager routinely monitored Web Surfing among her company\'s employees. She discovered that many employees were visiting the \"sinful six\" web sites (Note: The \"sinful six\" are web sites with material related to pornography, gambling, hate, illegal activities, tastelessness and violence.) She then prepared a list of the employees and their surfing histories and gave the list to management. Some managers punished their employees. Some employees, in turn, objected to the monitoring claiming that they should have a right to privacy.With this in mind, please answer the following two questions: a- Is monitoring of web surfing by managers ethical, (it is legal to do this)? -- Support your answer. b- Is employee web surfing on the \"sinful six\" ethical? Support your answers. 2-Discuss the idea that an information system by itself can rarely provide a sustainable competitive advantage. Justify your position. 3- Discuss why the Sarbanes-Oxley Act is having an impact on information security. Support your answer. 4- How are the network applications of communication and collaboration related? Do communication tools also support collaboration? Give Examples. (NOTE: there are two questions that need to be answered in your response. I will be looking to see if both questions are answered accordingly) 5- Explain why master data management is so important in companies that have multiple data sources. Solution Ans 1. a) Yes, monitoring of web surfing is ethical and an important duty of both network administrator and Information Security managers too. Any unethical use of the system can be detected only by scrutinizing the system. Though in the given scenario, some employees think it to be intrusion of their privacy but using organizational resources for their own private uses, and that too surfing pornographic sites, in office hours is completely unethical both professionally and morally. As the company must have female employees too and surfing pornography in front of them has high probability of causing embarrassment to them. Company has provided the computer and internet connection for official works only but using them for own personal use is at all not acceptable. Hence it is the employees’ duty to use office provided computer and internet connection for office works only and not to stray into one of the “sinful six” websites. b) No, it is not ethical on part of the employee to surf sites like “sinful six”. Firstly, the organization must definitely have female employees and surfing pornographic sites will definitely cause embarrassment to them. Secondly, the computer and internet resources provided by the company are for official purpose only. Wasting company resources and time on visiting sites related to pornography, gambling is not ethical for employees. Thirdly, several companies have clearly stated policies on refraining use of official IT resources on visiting sites especially related to pornography or gambling. Hence .

1. Europeans view Americans as people similar in ideas and culture. However, Americans tend to disagree with the European viewpoint. This situation exemplifies _____. Solution Cultural Superiority or \"Ethnocentrism ================================== Ethnocentrism is judging another culture exclusively by the qualities and standards of one\'s own way of life. Ethnocentric people judge different gatherings in respect to their own ethnic gathering or culture, particularly with sympathy toward dialect, conduct, traditions, and religion. These ethnic refinements and subdivisions serve to characterize every ethnicity\'s one of a kind social personality.

(TRUE / FALSE) The use of swap rates rather than treasury rates as a basis for pricing fixed-rate debt came about partly as a result of events (such as the Russian debt default) causing “flights to quality” that distorted US treasury yields as reflective of true long-term risk.

Can a single magnetic pole (either a north pole or a south pole) be isolated? Can it exist by itself? Explain. Can a single charge (either a positive charge or a negative charge) exist by itself? List some sources of magnetic fields. How are they produced? What is the source of Earth\'s magnetic field? How does Earth\'s geographic North Pole correspond to a magnetic south pole? Explain. How do different poles (north and south) interact with each other (e.g. attract or repel). Solution a) single magnetic pole are hypothetical elements; mono poles can not exist ; and it is not possible to either seperate north pole or south pole. Magnetic poles exist always in pairs with north and south on either end , how small you cut a magnet into pieces even into atomic scale you will eventually creating a north and south pole but never a mono pole. b)Mono poles exist in electric field; a single positive charge can exist sperated from a single negative. but the net charge of the universe is alwasy zero ; we can creat positive and neagtive charges in pairs and seperate them individually , such that the existanceof one will not influence the other . but for evey positve charge in this universe there is a negative charge created. c)earth magnetic field is the alwasy present untill there is motion of the hot molten metallic currents at the centre of earth. in general current produces magnetic field ; some of the magnetic sources are hard disk drives have thin magnetic coating; magnetic compass needles and some naturally occuring magnetic materials. earth points its magnetic north to the magnetic south pole ; since earth behaves like a tiny magnet placed in magnetic field of sun. so a tiny magnetic always shows its geographic north to the magnetic south pole when placed near a magnet. d) opposite poles attract and like poles repel ; north repels north and south repels south ; north attracts south and vice versa.

Why are culture media sterilized before they are used? Do you think that slants are autoclaved before or after they are solidified? Explain. Solution Answer:-4:-The culture media are sterlized for preventing the explant from being infected by bacteria, spores or fungal infectuon. Its done through milipore filter because autoclaving would decompose the organic nutrients (Amino acids, vitamins, glucose) as they are thermo labile.

What recent and past actions have Canada and the US taken to counteract their exchange rates with the economy in such distress over the past 10 years? Solution Since 2007, the world has experienced a period of severe financial stress, not seen since the time of the Great Depression. This crisis started with the collapse of the subprime residential mortgage market in the United States and spread to the rest of the world through exposure to U.S. real estate assets, often in the form of complex financial derivatives, and a collapse in global trade. Many countries were significantly affected by these adverse shocks, causing systemic banking crises in a number of countries, despite extraordinary policy interventions. Systemic banking crises are disruptive events not only to financial systems but to the economy as a whole. Such crises are not specific to the recent past or specific countries – almost no country has avoided the experience and some have had multiple banking crises. While the banking crises of the past have differed in terms of underlying causes, triggers, and economic impact, they share many commonalities. Banking crises are often preceded by prolonged periods of high credit growth and are often associated with large imbalances in the balance sheets of the private sector, such as maturity mismatches or exchange rate risk, that ultimately translate into credit risk for the banking sector. Crisis management starts with the containment of liquidity pressures through liquidity support, guarantees on bank liabilities, deposit freezes, or bank holidays. This containment phase is followed by a resolution phase during which typically a broad range of measures (such as capital injections, asset purchases, and guarantees) are taken to restructure banks and reignite economic growth. It is intrinsically difficult to compare the success of crisis resolution policies given differences across countries and time in the size of the initial shock to the financial system, the size of the financial system, the quality of institutions, and the intensity and scope of policy interventions. With this caveat we now compare policy responses during the recent crisis episode with those of the past. The policy responses during the 2007-2009 crises episodes were broadly similar to those used in the past. First, liquidity pressures were contained through liquidity support and guarantees on bank liabilities. Like the crises of the past, during which bank holidays and deposit freezes have rarely been used as containment policies, we have no records of the use of bank holidays during the recent wave of crises, while a deposit freeze was used only in the case of Latvia for deposits in Parex Bank. On the resolution side, a wide array of instruments was used this time, including asset purchases, asset guarantees, and equity injections. All these measures have been used in the past, but this time around they seem to have been put in place quicker (for detailed informatio.

What are the protocols in data transfer between CAD systems? Which one is most widely used? What types of data may not be transferred accurately or correctly? Solution Answer- Transferring CAD files electronically is the norm, rather than the exception, for today\'s manufacturing world. In the past, shops relied on blueprints.File translation is a process in which one data format is converted into another. File translators are written independently by each CAD or CAM software company. Some design teams may use several different types of CAD packages to communicate with different teams or complete specific functions. One design model may be exported and imported into several CAD packages before the final file reaches manufacturing. There are numerous file formats on the market today. You can encounter IGES, CADL, DXF, ASCII, NCAL, PAR, PRT, SAT, SUP, STL, X_T, MODEL, the various European and American automotive formats, and other file extensions.The International Standards Organization (ISO) is working with American, European and Asian businesses and government agencies to implement a standard for transferring electronic data, called the International STandard for the Exchange of Product Model Data (STEP).STEP, called Application Protocols (APs), which are built into a common data model. A well-built CAM translator translates all types of files quickly and accurately.

What do you think is the best medium for transmission of a signal? Please explain your answer. Solution TRANSMISSION MEDIA The means through which data is transformed from one place to another is called transmission or communication media. There are two categories of transmission media used in computer communications. 1. BOUNDED MEDIA: Bounded media are the physical links through which signals are confined to narrow path. These are also called guide media. Bounded media are made up o a external conductor (Usually Copper) bounded by jacket material. Bounded media are great for LABS because they offer high speed, good security and low cast. However, some time they cannot be used due distance communication. Three common types of bounded media are used of the data transmission. These are UNDUIDED MEDIA Unguided media, or wireless communication, transport electromagnetic waves without using a physical conductor. Unguided Transmission Media consists of a means for the data signals to travel but nothing to guide them along a specific path. The data signals are not bound to a cabling media and as such are often called Unbound Media. Signals are broadcast through air and thus are available to anyone who has a device capable of receiving them. In wireless communication, transmission and reception are achieved using an antenna. Transmitter sends out the electromagnetic signal into the medium. Receiver picks up the signal from the surrounding medium. Wireless transmission can be divided into three groups: radio waves, microwave, and infrared waves. The section of the electromagnetic spectrum defined as radio communication is divided into eight ranges, called bands. These bands are rated form very low frequency (VLF) to extremely high frequency (EHF). Transmission medium Unguided medium. There 4 basic types of Guided Media : Open Wire, Twisted Pair, Coaxial Cable, and Optical Fiber. Coaxial cable (or coax) carries signals of higher frequency ranges than twisted-pair cable. A fiber-optic cable is made of glass or plastic and transmits signals in the form of light..

We selected a sample of 14 respondents from the 2006 MTF. We present their number of moving (traffic) violations in the last 12 months along with their residential area (residential area is the independent variable). Use the proceeding output to discuss the significance of the F and P values. Is the relationship between city size and traffic violations significant? Solution Yes. The relationship between city size and traffic violations are significant. Because the P-value is 0.004, which is very less, so we reject the hypothesis that there is no relationship between city size and tarffic violations..

The following IP datagram is sent to a destination across a network with an MTU of 500. Using the first diagram, shows the header portions of the first two packet fragments that reach the destination (assuming arrival in order). Note all numbers are in base 10. Note that you should put a value in the data size space? Solution packet 1: packet 2: The data is of size 786 as in the total length field the value is 806 which is data+header. we know that the header length is 20bytes the data will be 786. The MTU is 500(both data and header) Therefore the 1st packet can send data upto 480 bytes. which is also equal to fragmentation offset because the next data has to be appended to these 480 bytes for complete information. the left out data is 306, so the total length is 326(306+20).As first packet could not carry the whole message it has to intimate the reciever there is more data to come, to indicate the flag value is set to 1, which is not the case in packet 2 so the flag is set to 0.45TOS500681480.

The baking yeast is the preferred organism to generate biofuels. However, it requires processed sugar to generate ethanol, which may put a strain on the food industry. Therefore, you decide to choose a photosynthetic organism to generate bioethanol. You select cyanobacteria. which use the sunlight as the primary energy for cell growth and proliferation. What are the two enzymes for which you would like to clone the coding genes and express in cyanobacteria? What are their respective substrate(s) and product(s)? Name the enzyme(s) that is/are also expressed in humans and describe its/their functions. Solution ans. The roke of yeast in production of ethanol is the most important element that distinguishes wine from grape juice, In the absence of oxygen that is under anerobic conditions yeast converts the sugar into ethanol and carbondioxide throufg the process of fermentation. 1, The two enzymes are pyruvate decaroxylase(pdc) and alcohol dehydrogenase. (adh) The coding sequence from both the enzymes frm the bacterium zymomonas is cloned into a shuttle vector pCB4r and then transform into cynobacteria strain 2. The major pathway for synthesis of bioethanol involves PDC catalyses the non oxidative decarboxylation of pyruvate which results in the production of acetaldehyde and carbon dioxide Acetaldehyde is then reduced to alcohol by alcohol dehydrogenase. PDC is tetramer of 4 identical subunit of 50kd mass. 2 isozymes of ADH present. 3. Enzymes in human for ethanol production is ADH4 which is present in gut.
