Provenance and geochemistry of exotic clasts in conglomerates of the Oligocene Torehina Formation, Coromandel Peninsula, New Zealand

Non-marine pebble to cobble conglomerates of the lower Torehina Formation (Oligocene) crop out along western Coromandel Peninsula and overlie, with strong angular discordance, continental-margin metasedimentary rocks (Manaia Hill Group) of Mesozoic (Late Jurassic to ?Early Cretaceous) age. The conglomerates contain provenance information that identifies a pre-Oligocene depositional history obscured by the unconformable juxtaposition of these Tertiary and Mesozoic strata. Most clasts in the lower Torehina Formation are visually similar to local bedrock lithologies, including metamorphosed sandstones and argillites, but are kaolinitic and contain more detrital and authigenic chert, quartz, and potash feldspar. Local derivation of these clasts seems unlikely. By comparing geochemical ratios with those defined for continental margin sandstones, and well characterised New Zealand tectonic terranes, we interpret the majority of clasts in the lower Torehina Formation to have been derived from a dissected orogen, with mixtures of felsic and volcanogenic-derived sediment. The most likely sources are the Waipapa and Torlesse Terranes. The remaining 20–30% of the clasts in the lower Torehina Formation were originally friable, are coarse grained, and appear to be lithologically exotic relative to known metamorphosed sandstones in basement terrane sources on North Island. Some clasts contain coal laminae and particles, and all contain detrital kaolinite as lithic fragments and matrix. Such characteristics imply a non-marine to marginal-marine source containing sediment derived from strongly weathered granite or granodiorite. Mechanical fragility implies a likely proximal, easily erodible source. We propose that this group of clasts was derived from an Upper Cretaceous sedimentary cover, either part of a locally developed basin fill or part of a once regionally extensive cover on North Island. Either case defines a more widely distributed Cretaceous source than found today

Using choice experiments to explore the spatial distribution of willingness to pay for rural landscape improvements

We report findings from a choice experiment survey designed to estimate the economic benefits from policy measures which improve the rural landscape under an agri-environment scheme in the Republic of Ireland. Using a panel mixed logit specification to account for unobserved taste heterogeneity we derive individual- specific willingness to pay estimates for each respondent in the sample. We subsequently investigate the existence of spatial dependence of these estimates. Results suggest the existence of positive spatial autocorrelation for all rural landscape attributes. As a means of benefit transfer, kriging methods are employed to interpolate willingness to pay estimates across the whole of the Republic of Ireland. The kriged WTP surfaces confirm the existence of spatial dependence and illustrate the implied spatial variation and regional disparities in WTP for all the rural landscape improvements

Lexicographic Preferences in Discrete Choice Experiments: Consequences on Individual-Specific Willingness to Pay Estimates

In discrete choice experiments respondents are generally assumed to consider all of the attributes across each of the alternatives, and to choose their most preferred. However, results in this paper indicate that many respondents employ simplified lexicographic decision-making rules, whereby they have a ranking of the attributes, but their choice of an alternative is based solely on the level of their most important attribute(s). Not accounting for these simple decision-making heuristics introduces systemic errors and leads to biased point estimates, as they are a violation of the continuity axiom and a departure from the use of compensatory decision-making. In this paper the implications of lexicographic preferences are examined. In particular, using a mixed logit specification this paper investigates the sensitivity of individual-specific willingness to pay (WTP) estimates conditional on whether lexicographic decision-making rules are accounted for in the modelling of discrete choice responses. Empirical results are obtained from a discrete choice experiment that was carried out to address the value of a number of rural landscape attributes in Ireland.Continuity axiom, Discrete Choice Experiments, Lexicographic Preferences, Mixed Logit, Individual-Specific Willingness to Pay

Using Discrete Choice Experiments to Derive Individual-Specific WTP Estimates for Landscape Improvements under Agri-Environmental Schemes: Evidence from the Rural Environment Protection Scheme in Ireland

Reported in this paper are the findings from two discrete choice experiments that were carried out to address the value of a number of farm landscape improvement measures within the Rural Environment Protection (REP) Scheme in Ireland. Image manipulation software is used to prepare photorealistic simulations representing the landscape attributes across three levels to accurately represent what is achievable within the Scheme. Using a mixed logit specification willingness to pay (WTP) distributions based on the parameter estimates obtained from the individual conditional distributions are derived. These estimates are subsequently adjusted and combined to account for baselines and levels of improvement resulting from the implementation of the REP Scheme. Individual-specific WTP estimates are thus obtained for the contribution of the Scheme to rural landscapes and are subsequently contrasted with the average cost of the Scheme across the Irish adult population. Results indicate that the Scheme contributes substantial benefits to rural landscapes.Agri-environment, Discrete choice experiments, Individual-specific WTP, Mixed logit

Gender, money and professional identity: medical social work and the coming of the British National Health Service

The published version can be accessed at the following link on the publisher’s website: https://doi.org/10.1080/09612025.2017.1328760The arrival of the British National Health Service (NHS) in 1948 heralded significant changes for all health workers, but the establishment of a ‘free’ health service was especially meaningful for the hospital almoners—or medical social workers, as they were starting to be known—who had previously been responsible for the assessment and collection of patient payments. It was on this basis they had gained a foothold in the hospital, capitalising on gendered assumptions of financial understanding and behaviour. Yet what might have caused an identity crisis was embraced. This was a dual strategy of both repositioning the profession in alignment with the planned NHS and of asserting an enhanced professional status by distancing themselves from the handling of payment. It was an episode in the history of this distinctly female profession that speaks to women’s historic relationship with money.Wellcome Trus

In-the-wild residual data research and privacy

As the world becomes increasingly dependent on technology, researchers endeavor to understand how technology is used, the impact it has on everyday life and the life-cycle and span of digital information. In doing so, researchers are increasingly gathering `real-world' or `in the wild' residual data, obtained from a variety of sources without the explicit consent of the original owners. This data gathering raises significant concerns regarding privacy, ethics and legislation, as well as practical considerations concerning investigator training, data storage, overall security and disposal. This paper surveys recent studies of residual data gathered in the wild and analyses the challenges that were faced. Taking these insights, the paper presents a compendium of practices for addressing the issues that arise in in the wild residual data research. The practices presented in this paper can be used to critique current projects and assess the feasibility of proposed future research

Micromagnetic Domain Structures in Cylindrical Nickel Dots

The magnetic domain structures of cylindrical nickel dots (diameters from 40 nm to 1700 nm) with anisotropy parallel to the cylinder axis is predicted by the ratio of the dot diameter to the stripe period of unpatterned films with the same perpendicular anisotropy. The dominant domain structure for a given ratio increases in complexity as the ratio increases. We present evidence for the full micromagnetic domain structure for the simplest cases
