The Panel Study of Income Dynamics (PSID) is a nationally representative longitudinal survey of approximately 9,000 families and their descendants that has been ongoing since 1968. Since 1969, families have been sent a mailing asking them to update or verify their contact information to keep track of their whereabouts between waves. Having updated contact information prior to data collection is associated with fewer call attempts and refusal conversion efforts, less tracking, and lower attrition. Given these apparent advantages, a study was designed in advance of the 2009 PSID field effort to improve the response rate of the contact update mailing. Families were randomly assigned to the following conditions: mailing design (traditional versus new), $10 as a prepaid versus postpaid incentive, timing and frequency of the mailing (July 2008 versus October 2008 versus both times) and whether or not they were sent a study newsletter. This paper reports on findings with regards to response rates to the mailing and the effect on production outcomes including tracking rates and number of calls during 2009 by these different conditions, examines whether the treatment effects differ by key characteristics of panel members including likelihood of moving and anticipated difficulty in completing an interview, and provides some recommendations for the use of contact update strategies in panel studies. 相似文献

A New Deal argues that engaged or participatoryart practice can be shown to be central rather than marginalto the meaning and value of art in the story ofhuman society, but only if we take a long view and change theposition from which we read and understand received history.It also argues that new models of art and institutional practiceare needed in the present, which foreground and validate participation,engagement and commonality – the reconnection of artistand community within social space. These new models are neededif we are to generate the new art forms that emancipate ratherthan disempower the citizen and which are not defined by thecul de sac of commodity and consumerism. 相似文献
