The effect of personalization on response rates and data quality in web surveys

Personalizing correspondence has often shown to significantly increase survey response rates in mail surveys. This study experimentally tests whether personalization of email invitations acts correspondingly to web survey response rates. Also, it is investigated whether personalization influences data quality. The results of the study, using a large student sample, show that personalization significantly increases the web survey response rate by 8.6 percentage points. The data quality does not appear to be affected in any major way by personalizing the email invitations. However, the analyses do show that respondents of the personalization condition tend to respond with more social desirability bias to sensitive questions. Therefore, it is concluded that personalization has positive effects on the survey response rate, but one should carefully consider whether or not to personalize when a survey on sensitive topics is conducted.     

Analyses of multiple types of online gambling within one provider: an extended evaluation framework of actual online gambling behaviour

The aim of this article is to extend previous publications of actual online gambling behaviour that neglected involvement across multiple types of gambling and did not provide levels of at-risk involvement. Behavioural data from 27,653 subscribers of an online gambling provider (bwin) in February 2005 were reanalysed across eight products over seven months. Established involvement levels of offline gambling segregated possible online at-risk gamblers. Forty-seven percent of the sample exceeded at least one of the two most conservative thresholds. Each additionally used gambling product increased the risk of transgressing involvement cut-offs by 3.06 to 4.27 times, but type-specific risks decreased strongly after adjusting for involvement in multiple gambling types. Only Poker and Live-action betting remained significant risk factors after adjustment. Taken together, cross-product analyses of gambling patterns lay the groundwork for an extended understanding of individual online gambling behaviour and overcome the methodological artefacts of isolated analyses.     

HIV/AIDS and Urbanization

It is well known that levels of HIV prevalence tend to be appreciably higher inurban areas. This article considers the reasons for this and shows that within world regions that are relatively homogeneous with respect to their experience of HIV/AIDS, variation in the level of urbanization corresponds to about one‐third of variation in estimated HIV prevalence. Furthermore, for populations in the world's worst‐affected area—eastern and southern Africa—there are signs that, partly by differentially raising urban death rates and depressing urban birth rates, HIV/AIDS is slowing the pace of urbanization. Finally, in countries with very high levels of HIV infection and relatively low birth rates, such as in South Africa, the urban sector will soon constitute a “demographic sink”—with death rates exceeding birth rates.     

DUST:

Following the perspective of "sociological miniaturism," proposed by Stolte, Fine, and Cook (2001), we examine the significance of dust in social life in order to examine the reverberations of the micro-features of everyday life on social structure. Through the examination of the routine, the unexamined, and the commonplace, we hope to gain some insight on how the taken-for-granted aspects of lived experience fit into the larger social order. Dust, by virtue of its "smallness," provides a window through which we can explore social structural issues using microsociological analysis. Specifically we examine how dust and techniques for its control are linked to issues of gender, work, political economy and nation.     

THE DOGIT ORDERED GENERALIZED EXTREME VALUE MODEL

This paper introduces the Dogit ordered generalized extreme value (DOGEV) model, for handling discrete variables that are ordered and heterogeneous. In particular, the DOGEV model can be applied to questionnaire responses on questions allowing a discrete set of ordered possible responses, where there is a preference for particular responses and possibly multiple modes in the data. The DOGEV model combines a model for choice set generation with the ordered generalized extreme value model. The paper illustrates the model using two empirical examples: a model of inflationary expectations and a model for students' evaluations of teaching.     

In the Frame: photovoice and mothers with learning difficulties

This paper presents the results of a photovoice project involving mothers with learning difficulties. Photovoice is a technique that challenges the established politics of representation by putting people in charge of how they document their own lives. The authors describe how the project was carried out and the problems they encountered. Analysis of the content of the mothers' photo albums in the context of their own personal stories throws light on both their individual lives and their collective experience. The results challenge discriminatory views of the women as different mums.     

'I have got my life back': users' experience of direct payments

After years of activism by disabled people's organizations, the Community Care (Direct Payments) Act 1996 made Direct Payment (DP) schemes a reality. Proponents of DP argue that it allows greater freedom and control for those people using it, but as these programmes only came into effect in 1997, few studies have tried to substantiate these claims. This paper reports on a two-year evaluation of two DP schemes in Wales. Using primarily users' feedback the paper focuses on the effects of DP and difficulties encountered, as well as why people chose—or did not choose—DP in the first place. User responses indicate a broad range of beneficial outcomes, including improved self-esteem, increased control over lives, deeper and more lasting relationships, and new interpersonal, vocational and lifestyle opportunities, as a result of the greater flexibility and freedom of choice enabled by DP. Family carers expressed similar satisfaction with DP schemes, also citing greater freedoms as a result of increased flexibility. While some potential users expressed concern over the administration of a DP scheme, users found that, with support from a user driven Independent Living Scheme, the administrative burden was manageable, and that ultimately the DP scheme was a welcome approach to support.     

Long-term safety of stimulant medications used to treat children with ADHD

Attention-deficit/hyperactivity disorder (ADHD) is a common mental health condition that affects children, adolescents, and adults. Because it is a chronic condition and typically requires effective treatment for several years or more, information on the benefits and risks of long-term pharmacotherapy for ADHD is vital to clinicians. This article reviews the emerging literature on the safety of long-term stimulant medications in ADHD-the most commonly prescribed medications for this condition. Common side effects, including cardiovascular effects, growth effects, and tics, are discussed, as well as treatment of children younger than age 6 and evidence of carcinogenic and reproductive effects.
