The components of landline telephone survey coverage bias. The relative importance of no-phone and mobile-only populations

The continuously growing mobile-only population raises concerns regarding the representativeness of traditional landline telephone surveys. At this time, the mobile-only population differs significantly from general population, which leads to coverage bias when using fixed-line samples only for telephone surveys. However, in many European countries the mobile-only population is not the only source of coverage bias in telephone surveys. In addition, we have to consider coverage biases caused by considerable proportions of citizens without any telephone service. Since these two groups differ from the general population with respect to differential socio-demographic categories, in our view, the negative effects of mobile-only coverage error in traditional landline telephone surveys might in fact compensate—in part—for coverage bias caused by the no-phone population. To test this hypothesis of compensating coverage biases we calculated relative coverage biases caused by the mobile-only population and relative coverage biases caused by the no-phone population in 30 European countries for two socio-demographic variables in two points in time. Results are presented for four groups of countries that differ with respect to no-phone and mobile-only rates. Results suggest that—in general—mobile-only biases and no-phone biases do not compensate to a great extent, and thus the alarming mobile-only biases cannot be neglected when using telephone surveys in the estimation of population parameters. Nevertheless, there are several countries where the bias caused by the mobile-only population is far bigger than the joint bias caused by the mobile-only population and the no-phone population. This finding suggests that biases caused by the recent mobile-only population would be even more severe if the no-phone population did not exist.     

Interviewing and surveying over the phone: a reflexive account of a research on parenting

This paper is on the role that the phone plays in a mixed-methods empirical research. In the current sociological literature, the phone is a methodological object associated with quantitative fieldwork, while little is said on the phone as a tool for qualitative research. We reflect here on a case study on the use of parental leaves by fathers in Spain, which included the phone as the only communication tool between researchers and subjects. We collect out own experience as interviewers in the qualitative phase of the research project, and interviewed surveyors working in the field. We analyze the discursive data following grounded theory principles and compare the use of both techniques in the data gathering process, including sampling and design. Thus, we consider interviewing and surveying as mediated communication situations. Our findings show that the value of the phone as a tool for research is a matter of adequacy to a given methodology, rather than an issue of validity, reliability, or credibility.     

In the frame: investigating the use of mobile phone photography in museums

• The ubiquitous use of mobile phone technology to capture photographic images has rapidly become an accepted feature of our social and cultural lifestyle. From the capture of photographic images in a social setting to the evening news reports of the 7/7 suicide bombings that led with phone video footage taken by a member of the public, mobile phone photography has rapidly become embedded in everyday life and presents a new set of challenges for marketers in all sectors. Within the heritage sector, mobile phone photography presents new methods for visitors to interact with and interpret historic sites, buildings and artefacts. This paper explores the use of mobile phone photography within the museum setting through an empirical study conducted at the National Football Museum in Preston, UK. It discusses the role of mobile phone photography in the visitor experience, in formal and informal learning provision, in stimulating the motivation to learn and in encouraging social interaction with visitor groups. The paper concludes with the identification of potential marketing opportunities for the museum and wider heritage sector.

Face-to-face versus telephone surveys on political attitudes: a comparative analysis

Several researchers declared that the telephone survey reaches more accurate voting tendencies than the face-to-face surveys. Telephone survey shows numerous advantages compared to a face-to-face one but, however, the telephone survey also has some inconveniences. Among these it is important to highlight the scant quality of the sampling frame; absence of a telephone in some homes and the wide expansion of the mobile phone; low response rate of certain collectives and the overrepresentation of others. There are also some new barrierswhich make access more difficult (e.g. the automatic answering phone) and the saturation of the telephone medium because of the large amount of publicity activities which generate a large number of “unsuccessful” calls and interruptedinterviews. The objective of this paper is evaluating the adaptation of the telephone surveys in the electoral forecasts; in an attempt to see if it shows substantial improvements when they are compared to face-to-face interviews.

Welfare effects of network neutrality in mobile Internet market

ABSTRACT

The network neutrality can enhance the profitability of content providers but reduce carrier platforms’ profits and consumer surplus. What is more, network neutrality can improve the total social welfare level when the external utility of mobile phone users to content providers is greater than that of content providers to those users. In addition, it is also found that both profitability of content providers and pricing power of carrier platforms for mobile phone users are directly proportional to the basic utility that carriers themselves can provide.

A three-stage model for smart phone use antecedents

Due to the widespread use of smart phones with enhanced functions, telecom service providers Have responded in a variety of contexts but have yet to attract enough customers as expected. Few studies have been conducted to understand antecedents for using smart phone mobile services in Taiwan. To acquire a better understanding of why people use smart phone mobile services, we used focus groups to investigate the smart phone consumption decision process. This study combined existing theories, Unified Theory of Acceptance and Use of Technology (UTAUT), perceived playfulness, with new factors discovered through focus groups, to develop a three-stage model for smart phone use antecedents. This model can be adopted by related operators and companies as a foundation for setting business strategies and marketing programs, and also as a reference for other researchers to examine the relationships in the model.
