淺談網絡中的遠程控制

摘要：在網絡高速發展的今天，隨著計算機應用的普及，遠程控制也逐漸被人們所關注。遠程控制是網絡的一大優勢，在網絡管理、遠程協作、遠程辦公等計算機領域都有著廣泛的應用，它進一步克服了由于地域性的差異而帶來的操作中的不便性，使得網絡的效率得到了更大的發揮。遠程控制可通過多種方法加以實現。關鍵詞：遠程控制；遙控操作；技術應用；實現方法 計算機遠程控制

計算機遠程控制是在網絡上由一臺電腦(主控端Remote／客戶端)遠距離去控制另一臺電腦(被控端Host／J]服務器端)的技術?。這里的遠程不是字面意思的遠距離，而是指通過網絡來對遠端的計算機實施遙控。

遠程控制只是通過網絡來操縱計算機的一種手段而已，只要運用得當，操縱遠程的計算機也就如同你操縱眼前正在使用的計算機一樣沒有任何區別。當操作者使用主控端電腦控制被控端電腦時，就如同坐在被控端電腦的屏幕前一樣，可以啟動被控端電腦的應用程序，可以使用被控端電腦的文件資料，甚至可以利用被控端電腦的外部打印設備和通信設備來進行打印和訪問互聯網。在這個過程中主控端電腦只是將鍵盤和鼠標的指令傳送給遠程電腦，同時將被控端電腦的屏幕畫面通過通信線回傳過來。也就是說，我們控制被控端電腦進行操作似乎是在眼前的電腦上進行的，實質是在遠程的電腦中實現的，不論打開文件，還是上網瀏覽、下載，所有的資料和上網等都是存儲在遠程的被控端電腦中的。

實行遠程控制，實際上就是一個服務器程序(以下簡稱被控程序)和一個客戶程序(以下簡稱主控程序)，被控方即為服務器程序，它監聽客戶的請求，并做出處理；主控方即為客戶程序，它連接上服務器后，發出自己的請求，服務器便根據客戶的請求做出不同的響應。遠程控制系統組成如圖1所示。

當今的遠程控制技術支持的網絡方式有：LAN、WAN、撥號方式、互聯網方式。此外，有的遠程控制軟件還支持通過串口、并口、紅外端口來對遠程機進行控制。遠程控制克服了由于地域性的差異而帶來的操作中的不便性，使得網絡的效率得到了更大的發揮。

2遠程控制的技術實現

2．1遠程控制的原理

“只要網絡有通路就可以實現遠程控制”，遠程控制必須通過網絡才能進行。位于本地的、已被安裝了客戶端程序的主控端是操縱指令的發出端，它像一個普通客戶一樣向非本地、安裝了服務器端程序的被控端發出信號，建立并通過一個特殊的遠程服務，使用各種遠程控制功能發送遠程控制命令，控制被控端電腦中的各種應用程序運行，使得被控端按照主控端的 要求進行各種操作，從而實現遠程控制的目的。圖2遠程控制示意圖

湖北大學本科畢業論文（設計）外文翻譯

通過網絡實現的遠程控制示意圖如圖2所示。

2．2遠程控制實現方法

2．2．1 利用微軟Windows XP系統中遠程控制功能

每臺Windows XP電腦都同時包括客戶端和服務器端，也就是說它既可以當成客戶端來連接其他的Windows XP電腦，也可以將自己當成服務器端，讓別的電腦來控制自己。服務器端的系統都是使用Windows XP，而客戶端就可以是Windows XP、Windows 2000或者Windows Me，并且對客戶端沒有語言的限制。用戶可以利用遠程桌面通過網絡對遠程計算機進行控制，控制后可以訪問所有應用程序、文件和網絡資源等。

2．2．2利用一些功能強大的遠程控制軟件。

遠程控制技術發展到今天，產生了許多優秀的遠程控制軟件，有提供多層次安全防護的遠程遙控軟件，還有加速遠程遙控操作軟件，以及更加利于快速文檔傳送的控制軟件。還有如“RemotelyAnywhere”只需在服務器端一次性安裝，客戶端在網絡中不需要再增加任何軟件，就可以直接通過瀏覽器來對服務器進行遠程控制。它不僅僅只是讓客戶端能夠遠程控制服務器的桌面，還可以給多個用戶設置不同的權限，以便讓他們根據授權對服務器的文件管理器、注冊表等項目進行查詢和管理；它允許服務器和客戶端之間傳遞剪貼板，也可實現普通文檔的傳送。另外，一些集遠程控制、數據通信和文件傳輸等功能于一體，具有很高的數據傳輸效率和系統安全保障的遠程控制系統正在被推廣。

2．2．3根據實際需求開發實現遠程控制

自行開發實現遠程控制，涉及主控機和受控機，故采用Client／Server結構。可以用Delphi編程環境分別在兩臺不同的電腦上編制控制和被控制程序，一個為Clientdpr．exe，裝在受控機上；另一個為Serverdpr．exe，裝在主控機上。Serverdpr．exe指定要監視的受控機的IP地址和發送指令給客戶機的Clientdpr．exe，客戶機的Clientdpr．exe得到指令后，接著在本機執行相應指令，將結果返回給主控機。主控方的功能是這樣實現的：讀取命令串一將命令串轉換成數組一清除內存流一指定目標計算機(通過讀取所輸入的IP地址)一將指令碼發送給目標計算機。當主控機將指令發給受控機后，受控機將在本機上調用Windows的應用程序接口API函數以執行所接收的指令。當受控機接收到數據時，便開始執行主控機發送的操作。具體操作是這樣的：讀取控制碼_+識別控制碼一執行相應的過程或API函數以達到相應的功能。結束語

遠程控制雖然可以方便地操縱遠程計算機，給人們帶來很多便利，但它也會由此帶來安全方面的隱患。隨著遠程控制市場的成熟，網絡安全變得越發重要，只有徹底解決這一關鍵問題，才能促進遠程控制真正走向應用。

Remote control of network

Abstract: The rapid development of the network today, with the popularization of computer applications, remote control have gradually been of concern to the people.Network remote control is a major advantage in network management, remote collaboration, remote office and other computer fields have a wide range of applications, it further to overcome regional differences in the operation brought the inconvenience, making the network efficiency Given greater play.Remote control can be achieved through a variety of ways.Keywords: remote control;remote operation;technology;Implementation 1 computer remote control

Computer remote control is on the network by a computer(host Remote / Client)remote to control another computer technology.Here is not the literal meaning of the long-distance remote, but rather through the network to the remote computer on the implementation of remote control.Remote control is to manipulate the computer through the network as a means only, if used properly, will control the remote computer as you manipulate the front of the computer being used as there is no difference.When the operator using the host computer control host computer to host computer as if sitting in front of the screen as the computer can start the host application, you can use the host computer documentation, or even Host computer using the external printing device and communications equipment to print and access the Internet.In this process, host computer is just a keyboard and mouse commands sent to the remote computer, while host computer's screen image come through the communication line return.That is, we control the host computer to operate in front of the computer seems to be carried out, in essence, a remote computer to achieve, whether to open the file, or Web browsing, downloading, all the information and the Internet are all Stored in the remote host computer.Implementation of remote control, in fact, a server program(hereinafter referred to as charged program)and a client(hereinafter referred to as master control program), the prosecution is the server program that listens to customer requests, and to deal with it;Master Is the client side, it is connected to the server, to make their request, the server will be made according to customer's request a different response.Remote control system shown in Figure 1.Today's technical support network remote control methods are: LAN, WAN, dial-up Internet way.In addition, some remote control software also supports serial, parallel, infrared port to control a remote machine.Remote control to overcome regional differences in the operation brought the inconvenience, make the network to play a greater efficiency.2 remote control technology 2.1 Principles of remote control

“As long as the network has access to connect remote control ”, remote control must be carried out through the network.At local, has been installed, the host is a client program to issue control instructions side, it is the same as an ordinary customer to non-local, the installation of the host server program signals, and through the establishment of a special Remote service, using a variety of remote control function to send a remote control command, control, host computers running various applications, making the host in accordance with the master's

Requirements for various operations, in order to achieve the remote control.Figure 2 Schematic diagram of the remote control

Remote control through the network diagram shown in Figure 2.2.2Implementation of Remote Control 2.2.1 Microsoft Windows XP system using the remote control function

Windows XP computers each include both client and server side, meaning that both can be used as a client to connect to other Windows XP computer, you can also themselves as the server side, so that other computer to control themselves.Server systems are using Windows XP, the client can be Windows XP, Windows 2000 or Windows Me, and the client without language restrictions.Users can use the Remote Desktop computer through the network to the remote control, after controlling for access to all applications, files and network resources.2.2.2 using some powerful remote control software.Remote control technology to today, have a lot of great remote control software, providing multi-level security protection for remote control software, as well as speed up the remote control operating software, and more conducive to the rapid document transmission control software.Also, as “RemotelyAnywhere” just a one-time installation on the server side, the client in the network do not need to add any software to connect directly through the browser on the server for remote control.It is not just the client to remotely control the server's desktop, but also can set different permissions for multiple users so that they are under the authority of the server's file manager, registry, query and manage projects;it allows the server and Clipboard passed between the client can also be transmitted to achieve common document.In addition, some set of remote control, data communications and file transfer and other functions into one, with high data transmission efficiency and system security remote control system is being promoted.2.2.3 Development and implementation of the actual needs of the remote control

Develop their own remote control, involving the host computer and controlled machines, so the use of Client / Server structure.Delphi programming environment can be used separately on two different computers to be controlled preparation of control and procedures, one for Clientdpr.exe, installed in the controlled machine;one for Serverdpr.exe, installed in the main computer on.Serverdpr.exe designated to monitor the controlled machine IP address and send instructions to the client Clientdpr.exe, client Clientdpr.exe get command, and then execute the corresponding instructions in the machine, the results are returned to the host computer.Master side function is implemented as follows: Read command string into a string array of commands to clear the memory of a stream to a specified target computer(by reading the entered IP address)to send the script to a target computer.When the command sent to the host computer controlled machine, the machine will be controlled on the unit's application program interface calls Windows API functions to perform the received command.When the controlled unit receives the data, they begin to send the host computer operation.To do this: Read identification control code _ + implementation of the corresponding control code for a procedure or function to achieve the appropriate API function.3 Conclusion

Although the remote control can easily manipulate the remote computer, to bring a lot of convenience, but it also the resulting security risks.As the market matures remote control, network security becomes more important, only solve this critical issue, to really go for remote

control applications.

第五篇：社交網站_外文翻譯

社交網站

我們定義的社交網絡站點作為基于Web的服務，允許個人：（1）有界系統內構建一個公共或半公共的配置文件。（2）闡明列表中的其他用戶，與他們共享一個連接。

（3）查看和遍歷他們的名單和那些由其他系統內的連接。性質和命名這些連接可能會有所不同，從站點到站點。

雖然我們使用的術語―社交網站‖來形容這種現象，―社交網站‖也出現在公共話語中，經常交替使用這兩個術語。我們選擇不采用―聯網‖的原因有兩個：重點和范圍。―物聯網‖強調關系啟動，往往陌生人之間。雖然網絡是可能在這些網站上，它是不是主要的做法，他們中的許多，也不是有什么區別他們從其他形式的計算機中介傳播（CMC）。

是什么讓獨特的社交網站并不是說他們允許個人見陌生人，而是他們讓使用者能夠表達，使人們看到他們的社交網絡。這可能會導致個人之間的連接，否則不會進行，但往往不是我們的目標，而這些會議之間―的潛在關系‖（Haythornthwaite，2005年）誰分享一些脫機連接頻繁。許多大型SNS網站，參與者不一定―網絡‖或尋找，以滿足新的人，相反，它們是人誰已經擴展社交網絡的一部分，他們的主要溝通。為了強調這一點明確的社會網絡，這些網站作為一個重要的組織特征，我們將它們標記―社交網站‖。

雖然SNS網站已經實施了各種各樣的技術特點，他們的骨干組成可見型材顯示鉸接式的Friends1誰也系統的用戶列表。配置文件是獨特的網頁，人們可以―輸入自己的應運而生‖（松登，2003年，第3頁）。在加入一個SNS，一個人被要求填寫表格，包含了一系列的問題。回答這些問題，這些問題通常包括描述符，如年齡，位置，興趣，和一個―關于我‖一節使用該配置文件。大多數網站還鼓勵用戶上傳的個人資料照片。有些網站允許用戶添加多媒體內容，或修改他們的個人資料的外觀和感覺，以提高他們的檔案。其他，如Facebook，允許用戶添加模塊（―應用程序‖），提高他們的個人資料。

在一個檔案中的知名度不同的網站，并根據用戶的自由裁量權。默認情況下，型材Friendster和Tribe.net被搜索引擎抓取，使他們的人看到，無論是否觀眾有一個帳戶。另外，LinkedIn的控制的基礎上，他或她是否有付費帳戶，觀眾可能會看到什么。像MySpace允許用戶來選擇他們是否希望他們的個人資料，以成為公眾或―朋友只。‖Facebook的一個不同的方法默認情況下，誰是在相同的―網絡‖的一部分用戶可以查看對方的輪廓，除非一個輪廓所有者已決定拒絕那些在其網絡的權限。結構變化的可視性和訪問社交網站區別于對方的主要方式之一。

加入一個社交網絡站點后，會提示用戶識別系統與他們有關系的人在。這些關系的不同而有所不同的標簽對網站熱門詞匯，包括―朋友‖，―聯系人‖和―粉絲‖，大多數SNS網站需要雙向確認的友誼，但有些則沒有。這些單向的關系有時會標示為―粉絲‖或―關注‖，但許多網站稱這些朋友。

―朋友‖一詞是誤導，因為連接并不一定意味著在日常白話感的友誼，人們連接的原因是多種多樣的（博伊德，2006A）。

公共顯示器的連接是SNS網站的重要組成部分。好友列表中包含鏈接到每個朋友的個人資料，使觀眾通過點擊好友列表遍歷網絡圖。在大多數網站，好友列表是可見的人誰被允許查看配置文件，但也有例外。例如，一些MySpace的用戶已經破解隱藏好友顯示他們的個人資料，LinkedIn允許用戶選擇退出顯示其網絡。

大多數SNS網站還提供了一種機制，用戶朋友的個人資料上留下消息。此功能通常涉及離開―的評論，‖雖然網站使用此功能的各種標簽。此外，SNS網站往往有一個私人消息功能類似的webmail。雖然私人消息和評論上流行的主要SNS網站，他們尚未普及。

并非所有的社交網絡網站等開始。

QQ作為中國的即時通訊服務，LunarStorm開始作為一個社區網站，賽我網作為韓國的討論區工具，以及環訊（原Skyblog）的加入SNS功能，是法國前博客服務。

Classmates.com，學校聯營公司在1995年推出的一個目錄，開始支持SNS網站走紅后，鉸接式好友列表。在2005-2006年與SNS的功能和結構，然后再重新啟動，MiGente AsianAvenue，BlackPlanet早期流行的民族社區網站與好友的功能有限。

雖然SNS網站的設計通常是普及，許多吸引同質人群最初，因此它并不少見找到組使用網站分開自己的國籍，年齡，教育程度，或其他因素，通常段的社會（Hargittai，這個問題）即使那是在沒有設計師的意圖。字的口碑策略有吸引力，因為他們結合消費者克服阻力顯著降低成本和快速的交付，尤其是通過技術，如互聯網的前景。不幸的是，目前scantregarding經驗證據的相對有效性口碑營銷提高企業績效隨著時間的推移。這就提出了一個需要研究企業如何測量WOM通信和口碑如何與其他形式的營銷傳播效果。

字的口碑營銷是互聯網上的一個特別突出的特點。互聯網為消費者提供了大量的場地，分享自己的觀點，喜好，或與別人的經驗，以及公司利用口碑營銷的機會。正如一位評論家指出，―折騰了數百萬美元的超級碗廣告，而不是初出茅廬的dot-com公司正試圖通過吸引注意力的營銷策略，如博客和[口碑]運動‖（2006年，惠特曼B3A頁）便宜得多。因此，重要的是要了解是否口碑才是真正有效的，如果是這樣，如何與傳統營銷活動的影響比較。

萬維網發展最快的舞臺之一是所謂的社交網站的空間。社交網站通常由一小群發送了邀請函，以自己的個人網絡的成員加入該網站的創始人發起的。反過來，新的

成員發送邀請到他們的網絡，等等。

因此，邀請函（即口碑推薦）網站獲得新的成員一直是最重要的推動力。隨著社交網站的成熟，他們可能會開始增加他們的傳統營銷工具的使用。因此，在這個階段，管理層可能會開始質疑口碑的相對有效性。

本研究的目的是開發和估計一個模型，捕捉新成員收購，口碑轉介，與傳統營銷活動之間的動態關系。在這樣做，我們提供一些貢獻。

首先，我們之間的第一次直接觀察到的口碑鏈接

吸納新客戶。其次，我們將展示如何配裝有口碑與傳統營銷的措施（例如，增加口碑營銷行動的活動，這反過來又增加了新的成員收購）的直接影響和間接影響。我們經驗證明，我們的數據集，新加入的會員UPS，這些營銷變量之間的內生性。這突出表明，需要考慮到這些間接影響口碑與傳統營銷的效果，以避免偏估計。第三，我們量化和對比口碑和傳統的營銷行動，立即和長期彈性。特別是，我們結轉效果強的口碑在我們的數據文件。最后，我們估計貨幣價值附加到每個口碑推薦，提供一個上限的財政獎勵管理可能會考慮提供口碑推薦。事實上，這種做法的播種或刺激口碑已迅速增長，但這一活動的有效性仍然很難量化（例如，戈德斯和Mayzlin 2004的）。

我們本文的其余部分組織如下：首先，我們總結前人的研究，以幫助的角度，把我們的貢獻。然后，我們描述我們的建模方法。接下來，我們提出了我們的實證分析的數據合作的互聯網社交網站，并提供理論和管理者的影響。特別是，我們發現，口碑推薦強烈影響收購新客戶，并具有比傳統的營銷形式由該公司與3至7天（21天）顯著較長的結轉。我們估計口碑的長期彈性為0.53-約20-30倍，高于傳統營銷的彈性。

Social Network Sites: Definition, History, and Scholarship

danah m.boyd, Nicole B.Ellison

Journal of Computer-Mediated Communication, Volume 13, Issue 1, pages 210–230, October 2007

Social Network Sites: Definition We define social network sites as web-based services that allow individuals to(1)construct a public or semi-public profile within a bounded system,(2)articulate a list of other users with whom they share a connection, and(3)view and traverse their list of connections and those made by others within the system.The nature and nomenclature of these connections may vary from site to site.While we use the term ―social network site‖ to describe this phenomenon, the term ―social networking sites‖ also appears in public discourse, and the two terms are often used interchangeably.We chose not to employ the term ―networking‖ for two reasons: emphasis and scope.―Networking‖ emphasizes relationship initiation, often between strangers.While networking is possible on these sites, it is not the primary practice on many of them, nor is it what differentiates them from other forms of computer-mediated communication(CMC).What makes social network sites unique is not that they allow individuals to meet strangers, but rather that they enable users to articulate and make visible their social networks.This can result in connections between individuals that would not otherwise be made, but that is often not the goal, and these meetings are frequently between ―latent ties‖(Haythornthwaite, 2005)who share some offline connection.On many of the large SNSs, participants are not necessarily ―networking‖ or looking to meet new people;instead, they are primarily communicating with people who are already a part of their extended social network.To emphasize this articulated social network as a critical organizing feature of these sites, we label them ―social network sites.‖

While SNSs have implemented a wide variety of technical features, their backbone consists of visible profiles that display an articulated list of Friends1 who are also users of the system.Profiles are unique pages where one can ―type oneself into being‖(Sundén, 2003, p.3).After joining an SNS, an individual is asked to fill out forms containing a series of questions.The profile is generated using the answers to these questions, which typically include descriptors such as age, location, interests, and an ―about me‖ section.Most sites also encourage users to upload a profile photo.Some sites allow users to enhance their profiles by adding multimedia content or modifying their profile’s look and feel.Others, such as Facebook, allow users to add modules(―Applications‖)that enhance their profile.The visibility of a profile varies by site and according to user discretion.By default, profiles on Friendster and Tribe.net are crawled by search engines, making them visible to anyone, regardless of whether or not the viewer has an account.Alternatively, LinkedIn controls what a viewer may see based on whether she or he has a paid account.Sites like MySpace allow users to choose whether they want their profile to be public or ―Friends only.‖ Facebook takes a different approach—by default, users who are part of the same ―network‖ can view each other’s profiles, unless a profile owner has decided to deny permission to those in their network.Structural variations around visibility and access are one of the primary ways that SNSs differentiate themselves from each other.After joining a social network site, users are prompted to identify others in the system with whom they have a relationship.The label for these relationships differs depending on the site—popular terms include ―Friends,‖―Contacts,‖ and ―Fans.‖ Most SNSs require bi-directional confirmation for Friendship, but some do not.These one-directional ties are sometimes labeled as ―Fans‖ or ―Followers,‖ but many sites call these Friends as well.The term ―Friends‖ can be misleading, because the connection does not necessarily mean friendship in the everyday vernacular sense, and the reasons people connect are varied(boyd, 2006a).The public display of connections is a crucial component of SNSs.The Friends list contains links to each Friend’s profile, enabling viewers to traverse the network graph by clicking through the Friends lists.On most sites, the list of Friends is visible to anyone who is permitted to view the profile, although there are exceptions.For instance, some MySpace users have hacked their profiles to hide the Friends display, and LinkedIn allows users to opt out of displaying their network.Most SNSs also provide a mechanism for users to leave messages on their Friends’ profiles.This feature typically involves leaving ―comments,‖ although sites employ various labels for this feature.In addition, SNSs often have a private messaging feature similar to webmail.While both private messages and comments are popular on most of the major SNSs, they are not universally available.Not all social network sites began as such.QQ started as a Chinese instant messaging service, LunarStorm as a community site, Cyworld as a Korean discussion forum tool, and Skyrock(formerly Skyblog)was a French blogging service before adding SNS features.Classmates.com, a directory of school affiliates launched in 1995, began supporting articulated lists of Friends after SNSs became popular.AsianAvenue, MiGente, and BlackPlanet were early popular ethnic community sites with limited Friends functionality before re-launching in 2005–2006 with SNS features and structure.While SNSs are often designed to be widely accessible, many attract homogeneous populations initially, so it is not uncommon to find groups using sites to segregate themselves by nationality, age, educational level, or other factors that typically segment society(Hargittai, this issue), even if that was not the intention of the designers.Word-of-mouth communication strategies are appealing because they combine the prospect of overcoming consumer resistance with significantly lower costs and fast delivery—especially through technology, such as the Internet.Unfortunately, empirical evidence is currently scantregarding the relative effectiveness of WOM marketing in increasing firm performance over time.This raises the need to study how firms can measure the effects of WOM communications and how WOM compares with other forms of marketing communication.Word-of-mouth marketing is a particularly prominent feature on the Internet.The Internet provides numerous venues for consumers to share their views, preferences, or experiences with others, as well as opportunities for firms to take advantage of WOM marketing.As one commentator stated, ―Instead of tossing away millions of dollars on Superbowl advertisements, fledgling dot-com companies are trying to catch attention through much cheaper marketing strategies such as blogging and [WOM] campaigns‖(Whitman 2006, p.B3A).Thus, it is important to understand whether WOM is truly effective and, if so, how its impact compares with traditional marketing activities.One of the fastest-growing arenas of the World Wide Web is the space of so-called social networking sites.A social networking site is typically initiated by a small group of founders who send out invitations to join the site to the members of their own personal networks.In turn, new members send invitations to their networks, and so on.Thus, invitations(i.e., WOM referrals)have been the foremost driving force for sites to acquire new members.As social networking sites mature, they may begin to increase their use of traditional marketing tools.Therefore, management may begin to question the relative effectiveness of WOM at this stage.The objective of this research is to develop and estimate a model that captures the dynamic relationships among new member acquisition, WOM referrals, and traditional marketing activities.In doing so, we offer several contributions.First, we are among the first to link observed WOM directly to new customer acquisition.Second, we show how toincorporate both the direct effects and the indirect effects of WOM and traditional marketing actions(e.g., a marketing action increases WOM activity, which in turn increases new member acquisition).We empirically demonstrate, for our data set, the endogeneity among new member sign-ups and these marketing variables.This highlights the need to account for these indirect effects to avoid biased estimates for both WOM and traditional marketing effects.Third, we quantify and contrast the immediate and long-term elasticities of WOM and traditional marketing actions.In particular, we document strong carryover effects for WOM in our data.Finally, we attach an estimated monetary value to each WOM referral, providing an upper bound to the financial incentive management might consider offering for WOM referrals.Indeed, the practice of seeding or stimulating WOM has grown rapidly, but quantifying the effectiveness of this activity remains difficult(e.g., Godes and Mayzlin 2004).We organize the remainder of this article as follows: We begin by summarizing previous research to help put our contributions in perspective.We then describe our modeling approach.Next, we present our empirical analysis of the data from a collaborating Internet social networking site and offer implications for theory and managers.In particular, we find that WOM referrals strongly affect new customer acquisitions and have significantly longer carryover than traditional forms of marketing used by the firm(21 days versus 3 to 7 days).We estimate a long-term elasticity for WOM of.53—approximately 20–30 times higher than the elasticities for traditional marketing.
