Internet Survey Response rates
Researchers often want to maximise response rates. Several studies have reported response rates for Internet surveys. These reports have varied greatly, and the lack of consistency in findings is likely due to the wide variation of factors across these studies. Sheehan and McMillan review some of the studies comparing email survey […]
Internet Surveys
While there is a mass of online surveys on the World Wide Web,’ there is still little published research on the factors that influence participants’ responses in Internet-administered surveys. As noted above, most empirical investigations of Internet survey methodology to date have appeared in market research journals (such as The International Journal of Market […]
It is an odd thing about the Internet that one can easily have a substantial number of people actively looking for studies to participate in. One can equally have a substantial number of people searching the Web looking for ways to test their skills in cracking into systems and having an impact on them. In […]

Hyphenation. List the treatment of frequently used terms that raise questions: Are they hyphenated, not hyphenated, or have they grown together to form one word? Is it day trading, day-trading, or daytrading? fiberoptic or fiber-optic? health care or healthcare? longer-term agreement or longer term agreement?
Capitalization. A style guide needn’t instruct writers to capitalize the first […]
While such approaches may be perfectly feasible (and we do not wish to discourage creative use of technology), it is always worth considering whether the target population has access to the software required. People can only participate in a study if they have the appropriate software installed and configured, so an effective approach is to […]
You have to learn a bit about online design in order to write design-style guidance for your Web documents (or to edit them intelligently), as well as to help publish user-friendly online style guides.
According to the Yale Style Guide, readers see pages and screens first as a blur of shapes, text blocks, and color. Then […]
Come on! Give the e-customer what he wants and stop messing him about. There is nothing very enjoyable about spending money on stuff that isn’t quite right because he can’t buy it the way he wants it.
Personalization
Personalization should mean exactly that. It must take the scope of `personal’ marketing beyond a glorified mailshot that proves […]

When I started covering the advertising business nearly thirty-five years ago, the media-buying function was firmly ensconced in the agencies. Although the media department was responsible for generating virtually all of the agency’s revenues, its responsibilities were relegated to newcomers in the business, young people right out of college, or women who had moved up […]

Throughout the history of the United States, one of the greatest political tensions has been that which balances personal privacy against the need for law enforcement to protect individuals and the country as a whole.
That tension has been with us from the very earliest days of the Republic. The Founding Fathers were extremely cognizant of […]
How do we know if we have any rows in a table? We use the COUNT function to return a count of the number of rows in a table. If you enter Listing into Query Analyzer we can check the data insert for the Spy table.
This will return the current number of rows (well actually […]
The introduction of SQL Server 2000 enables us to have multiple instances of SQL Server running on a single machine. In the past we only had one instance of SQL Server, which in SQL Server 2000 is called the Default instance. Now we can have as many named instances as we want. Microsoft has tested […]
User-defined functions (UDFs) rock! UDFs allow us to create compliant units of Transact-SQL that can return either a scalar value or a table.
A scalar value returns a single value (as our UDF did) of the type we specify in the CREATE FUNCTION statement.
A table returns a table of results. It leverages the new data type […]
SQL Server 2000 introduces the Copy Database Wizard and an enhanced version of the Index Tuning Wizard. Let’s take a look at both of these wizards, starting with the Index Tuning Wizard.
Tuning Indexes
The Index Tuning Wizard will assess your workload and give you suggestions for creating optimal indexes and statistics for your databases. The wizard […]
As you move into a multi-user environment, security, user, and resource management will become key to the performance and integrity of your application. Some of these security features are available on Windows 2000 only.
Understanding Kerberos and Security Delegation
Unfortunately, we cannot take advantage of these new enhancements. We are not running Windows 2000—maybe that’s a good […]
