. Explain the graph we received in the simulation that shows the relationship between the received (throughput) and sent (load) packets.

. Explain the graph we received in the simulation that shows the relationship between the received (throughput) and sent (load) packets. Why does the throughput drop when the load is either very low or very high?

 

2. Create three duplicates of the simulation scenario implemented in this lab. Name these scenarios Coax_Q2a, Coax_Q2b, and Coax_Q2c. Set the Interarrival Time attribute of the Packet Generation Arguments for all nodes in the new scenarios as follows: ❍ Coax_Q2a scenario: exponential(0.1) ❍ Coax_Q2b scenario: exponential(0.05) ❍ Coax_Q2c scenario: exponential(0.025) In all these new scenarios, open the Confi gure Simulation dialog box, and from the Object Attributes, delete the multiple-value attribute (the only attribute shown in the list). Choose the following statistic for node 0: Ethcoax · Collision Count. Make sure that the following global statistic is chosen: Global Statistics · Traffi c Sink · Traffi c Received (packet/sec). (Refer to the “Choose the Statistics” section in the lab.) Run the simulation for all three new scenarios. Get two graphs: one to compare node 0’s collision counts in these three scenarios and the other graph to compare the received traffi c from the three scenarios. Explain the graphs and comment on the results. ( Note: To compare results you need to select Compare Results from the Results menu after the simulation run is done.)

 

3. To study the effect of the number of stations on Ethernet segment performance, create a duplicate of the Coax_Q2c scenario, which you created in Exercise 2. Name the new scenario Coax_Q3. In the new scenario, remove the odd-numbered nodes, a total of 15 nodes (node 1, node 3, …, and node 29). Run the simulation for the new scenario. Create a graph that compares node 0’s collision counts in scenarios Coax_Q2c and Coax_Q3. Explain the graph and comment on the results.

 

4. In the simulation, a packet size of 1024 bytes is used. ( Note: Each Ethernet packet can contain up to 1500 bytes of data.) To study the effect of the packet size on the throughput of the created Ethernet network, create a duplicate of the Coax_Q2c scenario, which you created in Exercise 2. Name the new scenario Coax_Q4. In the new scenario, use a packet size of 512 bytes (for all nodes). For both Coax_Q2c and Coax_Q4 scenarios, choose the following global statistic: Global Statistics · Traffi c Sink · Traffi c Received (bits/sec). Rerun the simulation of Coax_Q2c and Coax_Q4 scenarios. Create the following graphs and explain them:

 

a. A graph that compares the throughput as packets per second in Coax_Q2c and Coax_Q4 scenarios

 

b. A graph that compares the throughput as bits per second in Coax_Q2c and Coax_Q4 scenarios

Describe your ordering system using Unified Modeling Language (UML) Use Case Diagrams.

Product Ordering System and Design Document

In the first Individual Project, you will be laying the groundwork for all of the work in this course. You will do the following:

  • Select a company and one of its products for which you will be creating an online ordering system. Get your instructor’s approval for your selections.
  • Install the required software.
  • Install the provided skeleton ordering system.
  • Customize the skeleton ordering system to meet your requirements.
  • Construct the shell document that will be your ordering system description.
  • Describe your ordering system using Unified Modeling Language (UML) Use Case Diagrams.

Now that you have a better understanding of object-oriented programming, you will use this approach to develop your interactive Java program that supports a company of your choosing to sell products online.

In this Individual Project, you will represent the design for your application using the UML diagramming techniques called use case diagrams. Later in the course, you will use another UML diagram to help design and describe your program, a class diagram.

You will also be setting up the foundation design document outline that you will add to each week. The combined Individual Project assignments will be your final Key Assignment design document deliverable.

Throughout this course, you will also be working on several aspects of this application that will result in the final version of a functioning interactive Java program. Additional information and the deliverables for each Individual Project will be provided in the assignment description for this project.

Project Selection

The first step will be to select a company and product(s) that are real or fictitious as the target for your ordering application. This project will be used as the basis for each of the assignments throughout the course, and it should conform to the following guidelines:

  • Nontrivial: The selected project company and products it sells should be realistic and only a few products (10 or fewer) should be described.
  • Domain knowledge: You should be familiar enough with the company and the products that it sells.

Select a company and products that fit these requirements, and submit your proposal to your instructor before proceeding further with the assignments in the course. You should seek approval within the first few days of the course. Your instructor will tell you how to submit this proposal and what notification will be given for project approval. Your proposal must include the following:

  • The name of the company
  • A description of the products
  • One specific product that you will use initially for your ordering system
  • The name of the product, its possible colors, and the range of costs

Briefly describe the technologies that led businesses into the second wave of electronic commerce.

Briefly describe the technologies that led businesses into the second wave of electronic commerce.

Answer: The increase in broadband connections in homes is a key element in the B2C component of the second wave. The increased use of home Internet connections to transfer large audio and video files is generally seen as the impetus for the large numbers of people spending the extra money required to obtain a broadband connection during the second wave. The increased speed of broadband not only makes Internet use more efficient, but it also can alter the way people use the Web. For example, a broadband connection allows a user to watch movies and television programs online—something that is impossible to do with a dial-up connection. This opens up more opportunities for businesses to make online sales. It also changes the way that online retailers can present their products to Web site visitors.

Another group of technologies emerged in the second wave that made new online businesses possible. The general term for these technologies is Web 2.0, and they include software that allows users of Web sites to participate in the creation, editing, and distribution of content on a Web site owned and operated by a third party. Sites such as Wikipedia, YouTube, and Facebook use Web 2.0 technologies.
Name and briefly describe the two business activities that were the earliest implementations of electronic commerce.

Answer: Since the mid-1960s, banks have been using electronic funds transfers (EFTs, also called wire transfers), which are electronic transmissions of account exchange information over private communications’ networks. Initially used to transfer money between business checking accounts, the use of EFTs gradually expanded to include payroll deposits to employees’ accounts, automatic payment of auto and mortgage loans, and deposit of government payments to individuals, such as U.S. Social Security System remittances.
Many business analysts have discussed the concept of the first-mover advantage. What are some of the disadvantages of being a first mover?

Answer: First movers must invest large amounts of money in new technologies and make guesses about what customers will want when those technologies are functioning. The combination of high uncertainty and the need for large investments makes being a first mover very risky. As many business strategists have noted, “It is the second mouse that gets the cheese.”

What are transaction costs, and why are they important considerations in electronic commerce?

Answer: Transaction costs are the total of all costs that a buyer and seller incur as they gather information and negotiate a purchase-sale transaction. Businesses and individuals can use electronic commerce to reduce transaction costs by improving the flow of information and increasing the coordination of actions. By reducing the cost of searching for potential buyers and sellers and increasing the number of potential market participants, electronic commerce can change the attractiveness of vertical integration for many firms.
How might a university use SWOT analysis to identify new degree programs that it could offer online?

Answer: In SWOT analysis, the analyst first looks into the business unit to identify its strengths and weaknesses. The analyst then reviews the environment in which the business unit operates and identifies opportunities presented by that environment and the threats posed by that environment.
In its early years, the Internet was a military project that became a science project with funding from the National Science Foundation. In one or two paragraphs, describe its transition to an environment that allowed and supported commercial activity.

Answer: In the early 1960s, the U.S. Department of Defense began examining ways to connect computers to each other and to weapons installations distributed all over the world. Employing many of the best communications technology researchers, the Defense Department funded research at leading universities and institutes. The goal of this research was to design a worldwide network that could remain operational, even if parts of the network were destroyed by enemy military action or sabotage. In 1969, Defense Department researchers in the Advanced Research Projects Agency (ARPA) used this direct connection network model to connect four computers—one each at the University of California at Los Angeles, SRI International, the University of California at Santa Barbara, and the University of Utah—into a network called the ARPANET. The ARPANET was the earliest of the networks that eventually combined to become what we now call the Internet.

E-mail was born in 1972 when Ray Tomlinson, a researcher who used the network, wrote a program that could send and receive messages over the network. This new method of communicating became widely used very quickly. As personal computers became more powerful, affordable, and available during the 1980s, companies increasingly used them to construct their own internal networks. Although these networks included e-mail software that employees could use to send messages to each other, businesses wanted their employees to be able to communicate with people outside their corporate networks.
In 1989, the NSF permitted two commercial e-mail services (MCI Mail and
CompuServe) to establish limited connections to the Internet for the sole purpose of exchanging e-mail transmissions with users of the Internet. These connections allowed commercial enterprises to send e-mail directly to Internet addresses, and allowed members of the research and education communities on the Internet to send e-mail directly to MCI Mail and CompuServe addresses..
In one or two paragraphs, explain what is meant by the term “Internet of Things.”

Answer: The most common perception of the Internet is that it connects computers to one another and, by doing so, connects the users of those computers to each other. In recent years, devices other than computers have been connected to the Internet, such as mobile phones and tablet devices. Once again, the connection of these devices to the Internet serves to connect the users of those devices to each other. However, the connection of devices to the Internet that are not used by persons is increasing rapidly. These devices—such as switches, optical scanners, sensors that detect changes in temperature, light, moisture, or the existence of vibration or movement—can be connected to the Internet and used by computers to manage automatically environmental conditions (such as heating and cooling or lighting levels) or security procedures. These interconnected devices can be located in houses, offices, factories, autos, appliances, and so on.

Computers can also be connected to each other using the Internet to conduct business transactions without human intervention. The subset of the Internet that includes these computers and sensors connected to each other for communication and automatic transaction processing is often called the Internet of Things.
Briefly describe the functions performed by routers in an interconnected network.

As an individual packet travels from one network to another, the computers through which the packet travels determine the most efficient route for getting the packet to its destination. The most efficient route changes from second to second, depending on how much traffic each computer on the Internet is handling at each moment. The computers that decide how best to forward each packet are called routing computers, router computers, routers, gateway computers (because they act as the gateway from a LAN or WAN to the Internet), border routers, or edge routers.
In about 100 words, explain the differences between a closed (or proprietary) architecture and an open architecture. In your answer, be sure to explain which is used for the Internet and why it is used.

Answer: The first packet-switched network, the ARPANET, connected only a few universities and research centers. Following its inception in 1969, this experimental network grew during the next few years and began using the Network Control Protocol (NCP). In the early days of computing, each computer manufacturer created its own protocol, so computers made by different manufacturers could not be connected to each other. This practice was called proprietary architecture or closed architecture. NCP was designed so it could be used by any computer manufacturer and was made available to any company that wanted it. This open architecture philosophy that was developed for the evolving ARPANET, included the use of a common protocol for all computers connected to the Internet and four key rules for message handling:

In about 100 words, describe the function of the Internet Corporation for Assigned Names and Numbers. Include a discussion of the differences between gTLDs and sTLDs in your answer.

Answer: Since 1998, the Internet Corporation for Assigned Names and Numbers (ICANN) has had the responsibility of managing domain names and coordinating them with the IP address registrars. ICANN is also responsible for setting standards for the router computers that make up the Internet.
Since taking over these responsibilities, ICANN has added a number of new TLDs. Some of these are generic top-level domains (gTLDs), which are available to specified categories of users. Note that ICANN is itself responsible for the maintenance of gTLDs. Other new domains are sponsored top-level domains (sTLDs), which are TLDs for which an organization other than ICANN is responsible.
The Web uses a client/server architecture. In about 100 words, describe the client and server elements of this architecture, including specific examples of software and hardware that are used to form the Web.

Answer: The Web is software that runs on computers that are connected to each other through the Internet. Web client computers run software called Web client software or Web browser software. Examples of popular Web browser software include Google Chrome, Microsoft Internet Explorer, and Mozilla Firefox.

Web browser software sends requests for Web page files to other computers, which are called Web servers and a Web server computer runs software called Web server software. The Web server software receives requests from many different Web clients and responds by sending files back to those Web client computers. Each Web client computer’s Web client software then renders those files into a Web page. Thus, the purpose of a Web server is to respond to requests for Web pages from Web clients. This combination of client computers running Web client software and server computers running Web server software is an example of a client/server architecture.
provide examples of at least two situations in which an organization would use XML and two situations in which an organization would use HTML.

Hypertext Markup Language (HTML) was derived from the more generic meta language SGML. HTML defines the structure and content of Web pages using markup symbols called tags. Over time, HTML has evolved to include a large number of tags that accommodate graphics, Cascading Style Sheets, and other Web page elements.

Although Extensible Markup Language (XML) is also derived from SGML, it differs from HTML in two important respects. First, XML is not a markup language with defined tags. It is a framework within which individuals, companies, and other organizations can create their own sets of tags.
Write a paragraph in which you describe the changes that occurred in virtual communities when the bandwidths available to Internet users increased.

Answer: In the mid-1990s, virtual communities formed in Web chat rooms and sites devoted to specific topics or the general exchange of information. As the bandwidths available to Internet users increased, photos and video became commonplace additions to the discussions in these communities.

Some companies use a social networking strategy in which they avoid making direct advertising or brand statements. In about 100 words, outline the advantages of that strategy.

Answer: Starbucks does not use social media to broadcast information about its products or build its brand. Instead, Starbucks uses social media to learn from their customers and find new ways to engage them with the company’s brand, products, and services. By intentionally avoiding active participation in its own social media outreach, Starbucks’ social media efforts are focused on listening to its customers’ discussions with each other and learning from those discussions.

By using social media to participate in the environment of an industry or product, companies can interact with their customers (or suppliers) in ways that are different from and more expansive than the roles traditionally taken in buyer–seller relationships.
In two or three paragraphs, describe the differences between a blog and a microblog. Be sure to discuss when a company might prefer to use a microblog in its social networking efforts rather than a blog.

Answer: Web logs, or blogs, are Web sites that contain commentary on current events or specific issues written by individuals. Many blogs invite visitors to add comments, which the blog owner may or may not edit. The result is a continuing discussion of the topic with the possibility that many interested persons will contribute to that discussion. Because blog sites encourage interaction among people interested in a particular topic, they are a form of a social networking site.
Sites such as Twitter are considered to be microblogs because they function as a very informal blog site with entries (messages, or tweets) that are limited to 140 characters in length.
In two or three paragraphs, outline at least three different ways in which a social networking site might monetize its visitors.

Answer: Small social networking sites that have a specialized appeal can draw enough visitors to generate significant amounts of advertising revenue, especially compared to the costs of running such a site. For example, software developer Eric Nakagawa posted a picture of a grinning fat cat on his Web site in 2007 with the caption “I can has cheezburger?” as a joke. He followed that with several more cat photos and funny captions over the next few weeks and added a blog so that people could post comments about the pictures. Within a few months, the site was getting more than 100,000 visitors a day. Nakagawa found that a site with that kind of traffic could charge between $100 and $600 per day for a single ad.

Although most social networking sites use advertising to support their operations, some do charge a fee for some services. For example, the Yahoo! Web portal offers most of its services free (supported by advertising), but it does sell some of its social networking features, such as its All-Star Games package. Yahoo! also sells other features, such as more space to store messages and attached files, as part of its premium e-mail service. These fees help support the operation of the social networking elements of the site.
In about 100 words, outline at least three ways in which a mobile phone’s GPS capabilities can be used to provide benefits to users of a social network.

Answer: Virtually all mobile devices have global positioning satellite (GPS) service capabilities, which means that apps can combine the phone user’s location with the availability of retail stores and services to create mobile business opportunities. For example, some apps can direct the user to specific business locations (such as restaurants, movie theaters, or auto repair facilities) based on the user’s current location.

Write a paragraph in which you describe the main task(s) performed by a Web server.

Answer: A Web server computer runs software called Web server software. Web server software receives requests from many different Web clients and responds by sending files back to those Web client computers. Each Web client computer’s Web client software renders those files into a Web page. Thus, the purpose of a Web server is to respond to requests for Web pages from Web clients.

In a paragraph or two, describe the two basic approaches that can be used to create dynamic Web pages.

Answer: Web site designers can incorporate dynamic content using two basic approaches. In the first approach, called client-side scripting, software operates on the Web client (the browser) to change what is displayed on the Web page in response to a user’s actions (such as mouse clicks or keyboard text input). In client-side scripting, changes are generated within the browser using software such as JavaScript or Adobe Flash. The Web client retrieves a file from the Web server that includes code (JavaScript, for example). The code instructs the Web client to request specific page elements from the Web server and dictates how they will be displayed in the Web browser.

In the second approach, called server-side scripting, a program running on a Web server creates a Web page in response to a request for specific information from a Web client. The content of the request can be determined by several things, including text that a user has entered into a Web form in the browser, extra text added to the end of a URL, the type of Web browser making the request, or simply the passage of time. For example, if you are logged into an online banking site and do not enter any text or click anywhere on the page for a few minutes, the Web server might end your connection and send a page to your browser indicating that “your session has expired.”
Write a paragraph in which you explain the purpose of a request message in a two-tier client-server architecture.

Answer: The basic Web client/server model is a two-tier model because it has only one client and one server. All communication takes place on the Internet between the client and the server. Of course, other computers are involved in forwarding packets of information across the Internet, but the messages are created and read only by the client and the server computers in a two-tier client/server architecture. The message that a Web client sends to request a file or files from a Web server is called a request message.

In about 100 words, describe how an n-tier architecture might be used by an online business. Include in your answer an outline of the functions that would likely be performed by computers configured in this way.

Answer: Architectures that have more than three tiers are often called n-tier architectures. N-tier systems can track customer purchases stored in shopping carts, look up sales tax rates, keep track of customer preferences, update in-stock inventory databases, and keep the product catalog current.
In a paragraph or two, explain why national laws designed to limit spam are largely ineffective.

Answer: Legal solutions to the spam problem have achieved only limited success in reducing spam because it is expensive for governments to prosecute spammers. To become cost effective, prosecutors must be able to identify spammers easily (to reduce the cost of bringing an action against them) and must have a greater likelihood of winning the cases they file (or must see a greater social benefit to winning).
The best way to make spammers easier to find has been to make technical changes in the e-mail transport mechanism in the Internet’s infrastructure.
In a paragraph, define throughput and response time. Explain why each is an important consideration in specifying a Web server hardware configuration.
Answer: Elements affecting overall server performance include hardware, operating system software, server software, connection bandwidth, user capacity, and type of Web pages being delivered. The number of users the server can handle is also important. This can be difficult to measure because both the bandwidth of the Internet connection and the sizes of the Web pages delivered can affect that number. Two factors to evaluate when measuring a server’s Web page delivery capability are throughput and response time. Throughput is the number of HTTP requests that a particular hardware and software combination can process in a unit of time. Response time is the amount of time a server requires to process one request.
Identify the benefits and costs of using a decentralized instead of a centralized server architecture in an online business operation. Summarize your findings in about 100 words.

Answer: Each approach (centralized and decentralized) has benefits and drawbacks. The decentralized architecture spreads risk over a large number of servers. If one server becomes inoperable, the site can continue to operate without much degradation in capability. The smaller servers used in the decentralized architecture are less expensive than the large servers used in the centralized approach. That is, the total cost of 100 small servers is usually less than the cost of one large server with the same capacity as the 100 small servers.

How To Give Orders Like a Man
by Deborah Tannen

The New York Times Magazine, August 28, 1994

A UNIVERSITY PRESIDENT WAS EXPECTING A VISIT FROM a member of the board of trustees. When her secretary buzzed to tell her that the board member had arrived, she left her office and entered the reception area to greet him. Before ushering him into her office, she handed her secretary a sheet of paper and said: “I’ve just finished drafting this letter. Do you think you could type it right away? I’d like to get it out before lunch. And would you please do me a favor and hold all calls while I’m meeting with Mr. Smith?”

When they sat down behind the closed door of her office, Mr. Smith began by telling her that he thought she had spoken inappropriately to her secretary. “Don’t forget,” he said. “You’re the president!”

Putting aside the question of the appropriateness of his admonishing the president on her way of speaking, it is revealing — and representative of many Americans’ assumptions — that the indirect way in which the university president told her secretary what to do struck him as self-deprecating. He took it as evidence that she didn’t think she had the right to make demands of her secretary. He probably thought he was giving her a needed pep talk, bolstering her self-confidence.

I challenge the assumption that talking in an indirect way necessarily reveals powerlessness, lack of self-confidence or anything else about the character of the speaker. Indirectness is a fundamental element in human communication. It is also one of the elements that varies most from one culture to another, and one that can cause confusion and misunderstanding when speakers have different habits with regard to using it. I also want to dispel the assumption that American women tend to be more indirect than American men. Women and men are both indirect, but in addition to differences associated with their backgrounds — regional, ethnic and class — they tend to be indirect in different situations and in different ways.

At work, we need to get others to do things, and we all have different ways of accomplishing this. Any individual’s ways will vary depending on who is being addressed — a boss, a peer or a subordinate. At one extreme are bald commands. At the other are requests so indirect that they don’t sound like requests at all, but are just a statement of need or a description of a situation. People with direct styles of asking others to do things perceive indirect requests — if they perceive them as requests at all — as manipulative. But this is often just a way of blaming others for our discomfort with their styles.

The indirect style is no more manipulative than making a telephone call, asking “Is Rachel there?” and expecting whoever answers the phone to put Rachel on. Only a child is likely to answer “Yes” and continue holding the phone — not out of orneriness but because of inexperience with the conventional meaning of the question. (A mischievous adult might do it to tease.) Those who feel that indirect orders are illogical or manipulative do not recognize the conventional nature of indirect requests.

Issuing orders indirectly can be the prerogative of those in power. Imagine, for example, a master who says “It’s cold in here” and expects a servant to make a move to close a window, while a servant who says the same thing is not likely to see his employer rise to correct the situation and make him more comfortable. Indeed, a Frenchman raised in Brittany tells me that his family never gave bald commands to their servants but always communicated orders in indirect and highly polite ways. This pattern renders less surprising the finding of David Bellinger and Jean Berko Gleason that fathers’ speech to their young children had a higher incidence than mothers’ of both direct imperatives like “Turn the bolt with the wrench” and indirect orders like “The wheel is going to fall off.”

The use of indirectness can hardly be understood without the cross-cultural perspective. Many Americans find it self-evident that directness is logical and aligned with power while indirectness is akin to dishonesty and reflects subservience. But for speakers raised in most of the world’s cultures, varieties of indirectness are the norm in communication. This is the pattern found by a Japanese sociolinguist, Kunihiko Harada, in his analysis of a conversation he recorded between a Japanese boss and a subordinate.

The markers of superior status were clear. One speaker was a Japanese man in his late 40’s who managed the local branch of a Japanese private school in the United States. His conversational partner was a Japanese-American woman in her early 20’s who worked at the school. By virtue of his job, his age and his native fluency in the language being taught, the man was in the superior position. Yet when he addressed the woman, he frequently used polite language and almost always used indirectness. For example, he had tried and failed to find a photography store that would make a black-and-white print from a color negative for a brochure they were producing. He let her know that he wanted her to take over the task by stating the situation and allowed her to volunteer to do it: (This is a translation of the Japanese conversation.)

On this matter, that, that, on the leaflet? This photo, I’m thinking of changing it to black-and-white and making it clearer. . . . I went to a photo shop and asked them. They said they didn’t do black-and-white. I asked if they knew any place that did. They said they didn’t know. They weren’t very helpful, but anyway, a place must be found, the negative brought to it, the picture developed.

Harada observes, “Given the fact that there are some duties to be performed and that there are two parties present, the subordinate is supposed to assume that those are his or her obligation.” It was precisely because of his higher status that the boss was free to choose whether to speak formally or informally, to assert his power or to play it down and build rapport — an option not available to the subordinate, who would have seemed cheeky if she had chosen a style that enhanced friendliness and closeness.

The same pattern was found by a Chinese sociolinguist, Yuling Pan, in a meeting of officials involved in a neighborhood youth program. All spoke in ways that reflected their place in the hierarchy. A subordinate addressing a superior always spoke in a deferential way, but a superior addressing a subordinate could either be authoritarian, demonstrating his power, or friendly, establishing rapport. The ones in power had the option of choosing which style to use. In this spirit, I have been told by people who prefer their bosses to give orders indirectly that those who issue bald commands must be pretty insecure; otherwise why would they have to bolster their egos by throwing their weight around?

I am not inclined to accept that those who give orders directly are really insecure and powerless, any more than I want to accept that judgment of those who give indirect orders. The conclusion to be drawn is that ways of talking should not be taken as obvious evidence of inner psychological states like insecurity or lack of confidence. Considering the many influences on conversational style, individuals have a wide range of ways of getting things done and expressing their emotional states. Personality characteristics like insecurity cannot be linked to ways of speaking in an automatic, self-evident way.

Those who expect orders to be given indirectly are offended when they come unadorned. One woman said that when her boss gives her instructions, she feels she should click her heels, salute, and say “Yes, boss!” His directions strike her as so imperious as to border on the militaristic. Yet I received a letter from a man telling me that indirect orders were a fundamental part of his military training. He wrote:

Many years ago, when I was in the Navy, I was training to be a radio technician. One class I was in was taught by a chief radioman, a regular Navy man who had been to sea, and who was then in his third hitch. The students, about 20 of us, were fresh out of boot camp, with no sea duty and little knowledge of real Navy life. One day in class the chief said it was hot in the room. The students didn’t react, except perhaps to nod in agreement. The chief repeated himself: “It’s hot in this room.” Again there was no reaction from the students.

Then the chief explained. He wasn’t looking for agreement or discussion from us. When he said that the room was hot, he expected us to do something about it — like opening the window. He tried it one more time, and this time all of us left our workbenches and headed for the windows. We had learned. And we had many opportunities to apply what we had learned.

This letter especially intrigued me because “It’s cold in here” is the standard sentence used by linguists to illustrate an indirect way of getting someone to do something — as I used it earlier. In this example, it is the very obviousness and rigidity of the military hierarchy that makes the statement of a problem sufficient to trigger corrective action on the part of subordinates.

A man who had worked at the Pentagon reinforced the view that the burden of interpretation is on subordinates in the military — and he noticed the difference when he moved to a position in the private sector. He was frustrated when he’d say to his new secretary, for example, “Do we have a list of invitees?” and be told, “I don’t know; we probably do” rather than “I’ll get it for you.” Indeed, he explained, at the Pentagon, such a question would likely be heard as a reproach that the list was not already on his desk.

The suggestion that indirectness is associated with the military must come as a surprise to many. But everyone is indirect, meaning more than is put into words and deriving meaning from words that are never actually said. It’s a matter of where, when and how we each tend to be indirect and look for hidden meanings. But indirectness has a built-in liability. There is a risk that the other will either miss or choose to ignore your meaning.

ON JAN. 13, 1982, A FREEZING COLD, snowy day in Washington, Air Florida Flight 90 took off from National Airport, but could not get the lift it needed to keep climbing. It crashed into a bridge linking Washington to the state of Virginia and plunged into the Potomac. Of the 79 people on board, all but 5 perished, many floundering and drowning in the icy water while horror-stricken bystanders watched helplessly from the river’s edge and millions more watched, aghast, on their television screens. Experts later concluded that the plane had waited too long after de-icing to take off. Fresh buildup of ice on the wings and engine brought the plane down. How could the pilot and co-pilot have made such a blunder? Didn’t at least one of them realize it was dangerous to take off under these conditions?

Charlotte Linde, a linguist at the Institute for Research on Learning in Palo Alto, Calif., has studied the “black box” recordings of cockpit conversations that preceded crashes as well as tape recordings of conversations that took place among crews during flight simulations in which problems were presented. Among the black box conversations she studied was the one between the pilot and co-pilot just before the Air Florida crash. The pilot, it turned out, had little experience flying in icy weather. The co-pilot had a bit more, and it became heartbreakingly clear on analysis that he had tried to warn the pilot, but he did so indirectly.

The co-pilot repeatedly called attention to the bad weather and to ice building up on other planes:

Co-pilot: Look how the ice is just hanging on his, ah, back, back there, see that?
. . .
Co-pilot: See all those icicles on the back there and everything?
Captain: Yeah.

He expressed concern early on about the long waiting time between de-icing:

Co-pilot: Boy, this is a, this is a losing battle here on trying to de-ice those things, it [gives] you a false feeling of security, that’s all that does.

Shortly after they were given clearance to take off, he again expressed concern:

Co-pilot: Let’s check these tops again since we been setting here awhile.
Captain: I think we get to go here in a minute.

When they were about to take off, the co-pilot called attention to the engine instrument readings, which were not normal:

Co-pilot: That don’t seem right, does it? [three-second pause] Ah, that’s not right. . . .
Captain: Yes, it is, there’s 80.
Co-pilot: Naw, I don’t think that’s right. [seven-second pause] Ah, maybe it is.
Captain: Hundred and twenty.
Co-pilot: I don’t know.

The takeoff proceeded, and 37 seconds later the pilot and co-pilot exchanged their last words.

The co-pilot had repeatedly called the pilot’s attention to dangerous conditions but did not directly suggest they abort the takeoff. In Linde’s judgment, he was expressing his concern indirectly, and the captain didn’t pick up on it — with tragic results.

That the co-pilot was trying to warn the captain indirectly is supported by evidence from another airline accident — a relatively minor one — investigated by Linde that also involved the unsuccessful use of indirectness.

On July 9, 1978, Allegheny Airlines Flight 453 was landing at Monroe County Airport in Rochester, when it overran the runway by 728 feet. Everyone survived. This meant that the captain and co-pilot could be interviewed. It turned out that the plane had been flying too fast for a safe landing. The captain should have realized this and flown around a second time, decreasing his speed before trying to land. The captain said he simply had not been aware that he was going too fast. But the co-pilot told interviewers that he “tried to warn the captain in subtle ways, like mentioning the possibility of a tail wind and the slowness of flap extension.” His exact words were recorded in the black box. The crosshatches indicate words deleted by the National Transportation Safety Board and were probably expletives:

Co-pilot: Yeah, it looks like you got a tail wind here.
Captain: Yeah.
[?]: Yeah [it] moves awfully # slow.
Co-pilot: Yeah the # flaps are slower than a #.
Captain: We’ll make it, gonna have to add power.
Co-pilot: I know.

The co-pilot thought the captain would understand that if there was a tail wind, it would result in the plane going too fast, and if the flaps were slow, they would be inadequate to break the speed sufficiently for a safe landing. He thought the captain would then correct for the error by not trying to land. But the captain said he didn’t interpret the co-pilot’s remarks to mean they were going too fast.

Linde believes it is not a coincidence that the people being indirect in these conversations were the co-pilots. In her analyses of flight-crew conversations she found it was typical for the speech of subordinates to be more mitigated — polite, tentative or indirect. She also found that topics broached in a mitigated way were more likely to fail, and that captains were more likely to ignore hints from their crew members than the other way around. These findings are evidence that not only can indirectness and other forms of mitigation be misunderstood, but they are also easier to ignore.

In the Air Florida case, it is doubtful that the captain did not realize what the co-pilot was suggesting when he said, “Let’s check these tops again since we been setting here awhile” (though it seems safe to assume he did not realize the gravity of the co-pilot’s concern). But the indirectness of the co-pilot’s phrasing certainly made it easier for the pilot to ignore it. In this sense, the captain’s response, “I think we get to go here in a minute,” was an indirect way of saying, “I’d rather not.” In view of these patterns, the flight crews of some airlines are now given training to express their concerns, even to superiors, in more direct ways.

The conclusion that people should learn to express themselves more directly has a ring of truth to it — especially for Americans. But direct communication is not necessarily always preferable. If more direct expression is better communication, then the most direct-speaking crews should be the best ones. Linde was surprised to find in her research that crews that used the most mitigated speech were often judged the best crews. As part of the study of talk among cockpit crews in flight simulations, the trainers observed and rated the performances of the simulation crews. The crews they rated top in performance had a higher rate of mitigation than crews they judged to be poor.

This finding seems at odds with the role played by indirectness in the examples of crashes that we just saw. Linde concluded that since every utterance functions on two levels — the referential (what it says) and the relational (what it implies about the speaker’s relationships), crews that attend to the relational level will be better crews. A similar explanation was suggested by Kunihiko Harada. He believes that the secret of successful communication lies not in teaching subordinates to be more direct, but in teaching higher-ups to be more sensitive to indirect meaning. In other words, the crashes resulted not only because the co-pilots tried to alert the captains to danger indirectly but also because the captains were not attuned to the co-pilots’ hints. What made for successful performance among the best crews might have been the ability — or willingness — of listeners to pick up on hints, just as members of families or longstanding couples come to understand each other’s meaning without anyone being particularly explicit.

It is not surprising that a Japanese sociolinguist came up with this explanation; what he described is the Japanese system, by which good communication is believed to take place when meaning is gleaned without being stated directly — or at all.

WHILE AMERICANS BELIEVE THAT “THE SQUEAKY wheel gets the grease” (so it’s best to speak up), the Japanese say, “The nail that sticks out gets hammered back in” (so it’s best to remain silent if you don’t want to be hit on the head). Many Japanese scholars writing in English have tried to explain to bewildered Americans the ethics of a culture in which silence is often given greater value than speech, and ideas are believed to be best communicated without being explicitly stated. Key concepts in Japanese give a flavor of the attitudes toward language that they reveal — and set in relief the strategies that Americans encounter at work when talking to other Americans.

Takie Sugiyama Lebra, a Japanese-born anthropologist, explains that one of the most basic values in Japanese culture is omoiyari, which she translates as “empathy.” Because of omoiyari, it should not be necessary to state one’s meaning explicitly; people should be able to sense each other’s meaning intuitively. Lebra explains that it is typical for a Japanese speaker to let sentences trail off rather than complete them because expressing ideas before knowing how they will be received seems intrusive. “Only an insensitive, uncouth person needs a direct, verbal, complete message,” Lebra says.

Sasshi, the anticipation of another’s message through insightful guesswork, is considered an indication of maturity.

Considering the value placed on direct communication by Americans in general, and especially by American business people, it is easy to imagine that many American readers may scoff at such conversational habits. But the success of Japanese businesses makes it impossible to continue to maintain that there is anything inherently inefficient about such conversational conventions. With indirectness, as with all aspects of conversational style, our own habitual style seems to make sense — seems polite, right and good. The light cast by the habits and assumptions of another culture can help us see our way to the flexibility and respect for other styles that is the only best way of speaking.
