Impact of Multimedia and Information Technology on Communications and Privacy.

Activities:

1. Identify, if you can, four different government departments that you expect would have a “file” on most people.
   
   

Note

This may depend on the students’ nationality, but likely to include the following government departments: - Birth, Marriage, Death register - Health/ Hospital/ Medicare record - Education history - Taxation history (personal income details) - Drivers license (and history of cancellations). There will be others that exist for “most” people….and lots that are specific to just some people (such as passport office, jail detention)…but these do not count for this question.

2. Do you think some people would have concerns if such files were to be amalgamated and cross checked? Why?
   
   

Note

In principle…when ever a person has given different information to two or more such government departments, then there is scope for such differences in information to be identified, and the person to be held to account for misinformation. For example, information about income, place of residence, medical conditions. There may also be concern that information that is considered personal and private should only be disclosed on an as-need basis. For example, a personal history of adoption, or a medical history that indicates treatment for cancer, should not be disclosed in the context of Education, or to the people who the person needs to deal with in such educational institutions.

3. Identify, if you can, four different businesses that you think may have a “file” on you.

Note

This will vary for each student, but may include the following business types: - Groceries or supermarket (food, drink, toilet paper, pet food, cigarettes) - Bottle shop (beer, spirits, wine) - Garage (type of car or motor bike, repair history) - Computer store (software and hardware) - Electronics goods store (TV, stereo) - Chemist (medications, prescription drugs) You may or may not also consider: - Banks (account types, wealth, mortgages) - Insurance (possessions, locations, value)

4. Do you think some people would have concerns if such files were to be amalgamated and provided to the public domain? Why?....and of what use is such information to other businesses…  and who OWNS such information?
   
   

Note

Some people – yes….but perhaps not all. Essentially, ones’ consumer habits may be considered to be ones’ own business. Whether a person consumes excessive amounts of soft drink (or alcohol), cigarettes, needs their car repaired “often” due to crashes, owns lots of expensive computer hardware and plasma televisions, or is required to take a specified prescription drug, may all be the source of embarrassment for many. It may also offer an increased risk to the chance of burglary since the likely contents of their home are now disclosed. Remember too, that some businesses may pertain to aspects of sexuality (brothel), religion (church sponsorship), or ethnicity (restaurant type… such as Indian, Chinese, Thai, Mongolian… or any other ethnic food type). All of the above information is considered valuable in the context of direct marketing. Knowing the types of products purchased, the brands purchased and the relative volumes purchased, may encourage a manufacturer of a competing product to target a specified individual because they believe that the person is a likely potential customer. The issue of ownership of such information is…”tricky”. Each individual owns the information about themselves. Information freely given for a specified purpose must not be used outside of that purpose. Information given freely by an individual, but who does not realise the range of purposes that it could be used for, may be open to use as the fault can be argued to lie with the consumer for failing to fully inform themselves. Others may argue that there is a need to ensure consumers fully understand the intent of use before such consent may be granted. Consider the in-house purchase cards (store specific credit cards) used by many large chains of grocery stores. Such cards are argued to provide convenience to the consumer, and may also offer benefit by way of discounts….but the cards also explicitly identify the user, the purchases, the dates, the amounts spent…and so on. Over time this enables a profile of the customer to be defined….and this information may be a valuable item that, depending upon the circumstances, could then be on-sold to a third party.

5. Do you think that banks, medical centers and lawyers are suitable examples of businesses that could be considered above in Question 3 and Question 4? Explain your reasoning. What differences do you think exist between these businesses and those that typically sell grocery items or newspapers?

Note

Students are free to see businesses such as banks, medical centers and lawyers as appropriate (or inappropriate) to their answers to Question 3 and Question 4 above. It depends on personalised point of view. The point here is that governments (and society) have historically considered personalised information about finances, medical conditions and legal records to be protected by law and to represent areas of a moral-right to privacy. It is generally illegal to pass such information to anyone who does not hold a legal right to access it. The individual in question will often be required to authorise such disclosure by signing a release form. Release of such personal information (finances, medical, legal) to the public domain may clearly be harmful to the individual in question. The changing market place means that lots of data is now often collected about a wide range of purchases (both goods and services) that an individual may make. Such benign information as grocery items purchased may lead to personal implications not realised as achievable, by techniques such as data mining. The whole area of “privacy” needs to be re-evaluated in the context of data about individual consumer behavior.

6. In undertaking the discussions above ….is it possible that anyone’s privacy has been breached? Explain your reasoning.

Note

The top of this tutorial question sheet specified to students to: “Only provide information about yourself that you are comfortable providing in a public domain.” I am trying to ensure that no participant finds themselves in the situation where he or she has disclosed information about their consumer habits (shops used, products purchased) that may result in embarrassment, harassment, or vilification. It is important to note, however, that in principal there are people who may experience embarrassment, harassment, or vilification if details of their purchasing habits were to be provided to the public domain. These are some of the specific risks that arise from data mining and direct marketing.

7. Identify three (possible) advantages in using email compared to phone conversations.

Note

This will vary between students, but advantages of email over phone conversations may include: - provides a hard copy record of what was said or what advice was given - enables one to consider carefully their wording in comments, questions, argument, or complaint…to thus avoid “speaking in the heat of the moment” - enables one to pen their thoughts at any time of day….even if the person to whom it is directed is absent or asleep. - can write, send and receive emails without causing disruption (or at least minimal disruption) to those around them. (NOTE: I am not suggesting that you should attend to emails during a class)

8. Identify three (potential) disadvantages in using email compared to phone conversations.

Note

This will vary between students, but disadvantages of use of email over phone conversations may include: - much less personal to communicate in writing than by conversation - absence of intonations indicating excitement or confusion, laughter and other verbal cues that do not translate easily to text. - does not generally provide immediate (real-time) feedback, ensuring that one “knows” the message has been received. - generally takes longer to write material than to speak it.

9. To what extent do you use email and phones (including SMS) differently?
   
   

Note

This will vary between students. All options are acceptable here because the question is capturing personal habits. In general, however, I anticipate that phones are used more with ones’ close network of friends (contained within their phone listing), while Emails are used more for “formal” communications with institutions such as universities, and government departments. Emails are also likely to be used between close friends when there is a need to “document” the conversation (such as a collaborative assignment, or preparing to book plane tickets for a shared holiday) or when there may be large cost implications for phone usage (due to being in different locations on the globe)….though applications such as Skype will impact upon this.

10. Are there practical alternatives to written signatures to demonstrate that you agree to something, such as a contract, provided by Information Technology?
    
    

Note

Some forms of alternative contract agreements are already in use, such as: - audio dialogue capture to demonstrate agreement to a contract presented by phone conversation (these are popular with phone companies undertaking direct marketing) - video capture of interviews, such as police interrogation. Note that these are “better” than a signature on paper because they more clearly indicate the dynamics of the situation to demonstrate if coercion is present, or the extent to which the words presented are or are not those of the person being interviewed. - mobile camera phones; these offer the potential for dedicated video capture available to the broad population, and have already been used to “document” events such as accidents, physical attacks or verbal abuse.

Cybertechnology in Industry, Manufacturing, Business and Commerce.

Activities:

1. Provide an example of how Cybertechnology (such as computers, robots, automated machinery) may be used in heavy industry (such as mining). What benefits do you think derive from such use?

Note

Some aspects of underground mining may be conducted by automated equipment, such as drilling. Such machines can undertake at least some of the hazardous tasks, thus reducing the risk of injury to human workers. Over the last few months there has been much in the media of potential negative consequences when things go wrong with oil wells tapped deep in the ocean (BP in USA). Although such drilling is done remotely and the response to the “leak” has been using robot submersibles, it is likely that the errors made leading to these event will lie with the decisions people made and how they executed them, not in the use of cybertechnology per se.

2. Provide an example of how Cybertechnology (such as computers, robots, automated machinery) may be used in manufacturing (such as automobile production or electronics). What benefits do you think derive from such use? What negative effects may be associated with this use?
   
   To what extent are the “negative” effects aligned to factors of social change?

Note

Some aspects of manufacturing may be conducted by automated equipment, such as robotic assembly lines. Examples include both “large” item manufacturing such as motor vehicles and “small” item manufacturing such as electronic goods or “micro” item manufacturing such as computer chips. Such machines can perform repetitive tasks with both a high degree of accuracy, and at a relatively high speed compared to human operators. One of the negative effects of such cybertechnology is the general loss of manual labouring jobs. The people who are made redundant from such positions need to be re-skilled in other tasks, which could include the operation and maintenance of such robotic assembly lines. Typically this results in many people who hold unskilled jobs needing to move towards higher skilled jobs.

3. Provide an example of how Cybertechnology may be used in business. What benefits can be demonstrated to derive from such use?
   
   How, if at all, do you think the use of this technology has impacted upon “redesigning” jobs?

Note

Almost all medium and large businesses today have the capacity to accept EFTPOS (Electronic Funds Transfer at Point of Sale). This facilitates more effective and more efficient management of financial transactions for both business and customers. Also, virtually all aspects of product inventory, stores, and ordering are now managed using information technology, such as a data base. Such tools add to the effectiveness (accuracy) and efficiency (less time required) of managing information. Due to the inroads that cybertechnology has made into the business world, most jobs in this sector have needed to be redesigned to incorporate use of computers into the structure of the tasks performed and general skill sets required, such as computer literacy. The vast majority of people employed in modern business contexts operate computers as part of their job, many having their own dedicated workstation.

4. Provide an example of how Cybertechnology may be used in commerce. What benefits can be demonstrated to derive from such use?
   
   What risks, if any, accrue from enabling “computer systems” to make “decisions” about the finance markets?
   
   

Note

Stock markets operate in real time with markets not only fluctuating day by day, but also throughout the day, sometimes quite dramatically in the space of minutes, and the effects can be at a global level. The advent of cybertechnology incorporating aspects of both computing and communication enable stock markets to operate efficiently and effectively at a global level. As the price of both commodities and the relevant exchange rates vary, opportunities are created for financial gain for those who have best utilized aspects of information and communication technology. Small shifts in markets can be leveraged by the purchase or selling literally billions of dollars in shares, stock, gold or international currencies. One risk to stock markets is over utilization of automated buy and sell prices. Should a rapid and dramatic rise or fall in the stock market occur, then there is scope for the automated computer systems to initiate trades over and above those that may have been deemed appropriate by a “live” (human) stock broker.

5. In the global context, what trends in outsourcing are occurring in Information and Communication Technology? Where (globally) are such markets expanding?
   
   How does outsourcing of “project management” for IT and software design, differ (if at all) to outsourcing of the production of code?
   
   

Note

By their nature, information and communication technology tasks are highly suitable to being undertaken on a global market because many of the tasks are such that they can be performed anywhere on the globe, with the job request and the result (finished product or outcome) being submitted electronically via the internet. India provides a relatively inexpensive labor force with many people skilled in IT who also have a good command of the English language. This has positioned India to work in IT within a global market. China is also rapidly expanding its capabilities in information and communication technology and is anticipated to provide another large pool of cost effective IT professionals in due course. While outsourcing of jobs in information and communication technology to India and China have been generally increasing, the focus is upon the production of code while much of the “project management” related tasks remain within the host country. This means that while a developed country such as USA, England or Australia may undertake the analysis and design aspects of a software design project, the actual production of code (or large portions of it) may be sent overseas to markets that provide relatively inexpensive IT expertise.

6. If you where required to purchase four new tires for a car…what would you do in order to acquire three quotes for comparative products (i.e.….phone, on-line, visit). Why?
   
   

Note

This will depend on each students experience and views…but typically I anticipate that many students would drive the car into the tire shop so that they can receive quotes and see the tires that they would receive. Once one quote had been obtained, and tire type desired identified, one could also then make use of a phone to obtain other quotes. There is also scope to use the web, but this is not likely to be the immediate first choice. The point of this question? To demonstrate that some purchases do not make much sense on-line. And with the tires…it starts getting silly to think that you may purchase them on-line and have them arrive a few days later in the mail for you to “install” yourself.

7. List three products that you believe are sensible for people to purchase on-line. Justify your answers.
   
   

Note

Any digital material such as software, music CD and movie DVD, because no matter where it is obtained from, all are “identical”….assuming of course they are not pirated copies. Similarly, books are an ideal item because once a specific title has been settled on (such as the textbook for this unit), then no matter where it is purchased from, the book will be the same. Any product line that is manufactured to a set standard (for example, from a specific brand and gauge of guitar strings to a seat on an airplane) can, in principle, be purchased on-line without impacting upon the quality of the purchased item.

8. List three products that you believe are not likely for people to purchase on-line. Justify your answers.
   
   

Note

Any piece of art work, be it a painting, ceramic pot, or mosaic, because there will be a strong desire to see the real object prior to purchase. Any musical instrument, be it a guitar, cymbal or piano, because there will be a strong desire to hear and feel the real object prior to purchase. Any new (untried) perfume, because there will be a strong desire to smell the real object prior to purchase. Fresh fruit and meats, because there will be a strong desire to “inspect” the food prior to purchase. Note that bulk orders and/or “regular” customers may in time come to “trust” the quality of the food and so then shift towards a state of acceptance of on-line purchase from a tried and tested provider.

9. Describe possible fears and risks people may hold with respect to purchasing items on-line. Provide some ways by which these risks may be minimised?
   
   

Note

People could have fear of personal credit details being misused to purchase additional items, or fear of personal details being misused to engage in identity theft for “other” purposes. Fear that the purchased goods will never arrive, or that the goods received will not be as represented prior to purchase (i.e. they will arrive either damaged or of inferior quality). To minimize risks options exist to: - insist on forms of security such as encryption. - use credit cards that have a relatively low limit - use a third party transaction company to manage the exchange.

10. Describe the relative advantages and disadvantages that you perceive in telecommuting. Do you have any strong preference for working from home verses an office? Note: this includes working as a student.
    
    

Note

Different people will have different views….but some ideas are: Advantages: No need to waste time and money on travel Cheaper for food because can make use of own kitchen Convenience of being able to work whenever the desire or ideas come Flexibility of mixing work with domestic duties such as child care No need to “dress up” for an office environment (such as in a suit).           - Indeed, no need to be dressed at all Peace and quiet without distractions. Disadvantages: Encroaching of work life into home life Loss of space within the home, due to the need to dedicate a room as an office Inability to escape distractions such as noisy children Loss of social interactions with peers and colleagues Some students will like the idea of telecommuting, but others will dislike the prospect. This may be an example of personal preferences being individualistic. Telecommuting will continue to evolve towards a powerful and immersive option to real commuting and real office work.

Using masks in Photoshop CS

What does using masks to select images enable you to do?

Control the precision of the edges of a selection
Define a selection based on color range
Delete background pixels from an image
Extract a foreground image element from its background



Which steps do you perform to extract an element from a photograph?

Apply a fill to the outlined image you want to extract
Draw a mask, place it over the image, and then use a crop tool to extract the image
Draw an extraction path around the image
Specify the color range of the image



Suppose you want to use the Background Eraser tool to select a foreground element in a photograph. What do you need to do to ensure that you mask only the background of the image?

Drag the circle - or brush - on the tool's cursor on the background only
Ensure that you drag the crosshair on the tool's cursor on the background only
Set the tool to use a large brush size
Specify the color range that the tool must mask




What effect does decreasing the fuzziness setting for a selection based on color range have?

It determines the resolution of the selection
It increases the color range and so decreases the sharpness of the edges of the selection
It restricts the color range and so sharpens the edges of the selection
