New voices in social work: an explorative study of female Turkish and Moroccan-Dutch professionals in social work in the Netherlands

In social work, the participation of Turkish and Moroccan-Dutch professionals, second and third generation migrant women from a Muslim background, is increasing. In this participative qualitative inquiry, new professionals were actively involved as co-researchers, doing research with peers from the same background. The question addressed is how these professionals deal with identity tensions and if they find positive sources of identification in social work. The new professionals claim a positive identity, connected to what they consider their strength and in particular their faith and ‘otherness’. At the same time, this increases their vulnerability, in a context in which Islam by some is considered a threat to society. The importance of a supportive professional social work identity is advocated.     

A validation of a computer-assisted randomized response survey to estimate the prevalence of fraud in social security

Summary.  In the Netherlands, there is a research tradition that measures fraud against regulations by interviewing eligible individuals using a survey. In these studies the sensitive questions about fraud are posed by using a randomized response method. The paper describes the results of a Dutch study into the consequences of replacing home interviews by trained interviewers with Internet-delivered interviews in a survey on fraud in the area of disability benefits. Both surveys used computer-assisted self-interviews with randomized response questions. This study has three goals: first to present the research tradition that makes use of randomized response, second to compare the results of home interviews and the Internet survey and finally to introduce an adapted weighted logistic regression method to test the relationship between the probability of fraud and explanatory variables. The results show that there are no systematic differences between modes of interview, either for estimates of the prevalence of fraud or for the identification of associated variables. These outcomes result in the conclusion that the Internet survey is a useful and cost-effective instrument for measuring fraud in a population, and that it is unlikely that replacing home interviews with the Internet survey will result in a significant break with tradition.     

The Influence of Advance Letters on Response in Telephone Surveys: A Meta-Analysis

Recently, the leading position of telephone surveys as the majormode of data collection has been challenged. Telephone surveyssuffer from a growing nonresponse, partly due to the generalnonresponse trend for all surveys and partly due to changesin society and technology influencing contactability and willingnessto answer. One way to counteract the increasing nonresponseis the use of an advance letter. In mail and face-to-face surveys,advance letters have been proven effective. Based on the proveneffectiveness in face-to-face and mail surveys, survey handbooksadvise the use of advance letters in telephone surveys. Thisstudy reviews the evidence for this advice and presents a quantitativesummary of empirical studies on the effectiveness of advanceletters in raising the response rate for telephone surveys.The major conclusion is that advance letters are also an effectivetool in telephone surveys, with an average increase in responserate (RR1) from 58 percent (no letter) to 66 percent (advanceletter), and an average increase in cooperation rate (COOP1)from 64 percent (no letter) to 75 percent (advance letter).
