Public Opinion toward NAFTA in the United States, Canada and Mexico: Insights from the Gallup World Poll

Abstract:

A commitment to continental free trade has been a major part of the trade policies of the United States, Canada and Mexico for the last 15 years – one embodied in the North American Free Trade Agreement (NAFTA). Public support for NAFTA and impressions of its effects have, however, remained mixed, and have varied over time. Still, attempts to examine public opinion across all three countries in the trade bloc remain few, with most studies limited to a single country. Drawing on data from the Gallup World Poll, we endeavor to remedy this situation by examining public impressions of NAFTA across all three member countries. Read more

Recruitment of Minorities Using Address-Based Sampling (ABS): A Pilot Study

Abstract:

The crisis in coverage of the landline telephone frame has reached a point where researchers are testing alternatives to (or at a minimum, complements to) traditional landline random digit dialing (RDD). Ideally, a new sampling methodology would address not only the coverage challenges posed by cell phone only households and unlisted households in zero-listed banks, but also provide a basis for developing survey designs that could address the growing nonresponse issue which also plagues traditional RDD approaches. One such approach proven to be promising and potentially cost effective involves use of address-based samples using large comprehensive databases, such as the U.S. Postal Service Delivery Sequence File (DSF).

Examining the Relationship Between Survey Response Elicitation Efforts, Respondent Motivation, and Satisficing: A Case Study of Web-based Panel Survey

Abstract:

Understanding the dynamics of survey participation, particularly about why people take part in surveys and, perhaps more importantly, why they do not, is often a challenging task at hand for survey researchers. A part of this challenge involves expending some form (e.g., e-mail or postcard reminder) of survey elicitation effort in obtaining a response. The general assumption as it pertains to Web-based surveys is that more motivated survey invitees respond with minimal elicitation effort (i.e., they respond even before the first reminder is sent), while their less motivated counterparts respond only with a subsequent increase in such efforts (i.e., sending more than one reminder) or choose to not respond.

Clarifying the “Progress” Of Progress Indicators

Abstract:

In Web surveys, progress indicators inform respondents of their progress, using a variety of design approaches. A graphic-based method usually involves the image of a progress bar, while a text-based method involves using simple text (often percent completed).  Sometimes a combination of graphic- and text-based designs is used (see Couper, Traugott, & Lamias, 2001; Heerwegh & Loosveldt, 2006). Progress indicators can also be displayed on every screen or intermittently, or at the respondents’ request (see Conrad et al., 2005).  The main argument for using a progress indicator is that it motivates respondents to complete the survey by making the end of the survey appear visibly nearer with every question answered.

Produce Food Safety in the Marketing Channel and the American Consumer

Abstract:

Publicity surrounding recent outbreaks of food-borne illness has raised concern among American consumers about the microbial safety of produce delivered through food marketing channels. In 2006 an E. coli outbreak was traced to spinach, resulting in millions of dollars in losses for the produce industry; in early 2008 a large salmonella scare linked to tomatoes also dampened industry profits. To investigate the effects of these concerns, a large random survey of American consumers from the Gallup Panel was performed in October 2008 to investigate the extent to which consumers were concerned about the microbial safety of produce and how they coped with those concerns in the food marketing channel.
