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.  相似文献

Abstract

This article examines Anna Kavan’s sojourn in New Zealand from February 1941 to November 1942 in the company of the pacifist playwright Ian Hamilton. Living in the most remote of the ex-British colonies reinforced Kavan’s ontological sense of homelessness and wish to disidentify from British society, yet the colony’s anglophone orientation offered familiarity within the strange and alien. The geography, landscapes and communities of its Pacific islands encouraged a reshaping of her imaginative engagement with otherness. Referring to Kavan’s recently published diary, ‘Five Months Further or What I Remember ab[ou]t New Zealand’, the essay argues that the New Zealand ‘experience’ encouraged her use of tropes of the Gothic and uncanny as she grappled with issues of distance, homelessness and disjunctive reality. The discussion focuses on the alternative/parallel world that New Zealand represents in stories published in I Am Lazarus (1945). It identifies experimental techniques associated with Gothic fiction by which Kavan registers the overlapping dualisms of war-torn London and idyllic rural New Zealand, and represents memory through framing devices and defamiliarizing rhetorical tropes as a distancing activity interrupting the present moment: dream sequences, irruptions into and splittings of reality, space and time reversals, doublings of self/other, disjunctive non sequiturs and ghostly mirror imaging.  相似文献

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.  相似文献

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.  相似文献
