Eliciting Risk Attitudes in the Field: Surveys or Experimental Methods? An Empirical Comparison in Rural Niger

We compare several risk preference elicitation methods – including incentivised, non-incentivised, and framed methods as well as a traditional Likert survey question – in a developing country and empirically test how well consequent measures of risk attitudes predict risk taking behaviour. We find that Likert scale and non-incentivised framed survey questions are not sufficient substitutes for costlier incentivised methods in rural Niger. Instead, the incentivised framed question works best while a simplified incentivised lottery question works almost as well. More risk and ambiguity averse farmers are less likely to adopt fertiliser microdosing indicating the importance of insurance and strategies to promote learning.     

Tracing the Flow of Policy Ideas in Legislatures: A Text Reuse Approach

This article proposes a new approach to investigating the substance of lawmaking. Only a very small proportion of bills become law in the U.S. Congress. However, the bills that do become law often serve as vehicles for language originating in other bills. We investigate “text reuse” methods as a means for tracing the progress of policy ideas in legislation. We then show how a focus on policy ideas leads to new insights into the lawmaking process. Although our focus is on relating content found within bills, the same methods can be used to study policy substance across many research domains.     

‘Fat cat’ lawyers and ‘illegal’ migrants: the impact of intersecting hostilities and toxic narratives on access to justice

ABSTRACT

This article examines how three spheres of hostility intersect to prevent effective access to justice for those living with insecure immigration status. The neoliberal governance model, the barren justice landscape and the hostile environment are supported by the cynical construction of the ‘fat cat’ lawyer and the toxic ‘folk devil’ narrative of the ‘bogus’ asylum seeker. To the extent that the judiciary have frustrated the more obvious, ideologically driven, attempts to restrict access to justice for migrants, the austerity predicated measures pursuant to the Legal Aid, Sentencing and Punishment of Offenders Act 2012 (LASPO) have completely altered the legal landscape. The analysis is informed by the findings of the ‘Legal advice and support for persons with insecure status’ project (hereafter LAPIS) in Nottingham which explores the challenges faced by service providers and the lived experiences of those with insecurity of status. It is clear that access to justice is a passport to the realisation of other rights, yet participants struggled to access a remedy because legal advice is too often out of reach.     

Estimating Individual Contributions to Complex DNA SNP Mixtures.,

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.
