The importance of accounting for unobserved heterogeneity, state-dependence and differences in residual variances across groups: An application to Irish Farmers land market participation decisions

working paperLand is an essential input into agricultural production. A grwoing literature is concerned with the factors influencing farmers’ land market participation decisions in developing countries, with developed countries largely ignored. Current best-practise in the land market participation literature is exemplified by Holden et al. (2007) who use a dynamic model which allows for state-dependence and unobserved heterogeneity. Much of the literature fails to adequately deal with these features of land market decisions. In addition, a single model is used to represent all farm types. In this paper, we firstly consider the factors influencing land market participation decisions in a developing country, Ireland, while allowing for state-dependence, unobserved heterogeneity and differences across farm tyes. We compare these results to those that are obtained while ignoring state-dependence, unobserved heterogeneity and differences between farm types. Our results suggest that some caution may be warranted when these aspects are ignored when if fact they are present

An Analysis of the Capitalisation of CAP Payments into Land Rental Rates in Ireland. Factor Markets Working Document No. 68, August 2013

EDITED VERSION SOON TO BE PUBLISHED In this paper the effect of decoupling on the capitalisation of agricultural subsidies into agricultural rents in Ireland are analysed using a dynamic rental equations estimated with a two step system GMM estimator that accounts for expectation error and endogenous regressors. The findings illustrate the importance of institutional details in determining the extent to which subsidies are capitalised. In the period prior to decoupling Pillar 1 subsidies were highly capitalised into Irish agricultural rents in both the short and the long run. Depending on the farm system considered between 58 to 80 cents per euro of subsidies were capitalised into agricultural rents. In the post decoupling period the rate at which Pillar 1 subsidies are capitalised into Irish agricultural rents is found to have declined. This change is likely due to short term character of the Irish agricultural land rental market, where 11 month rental periods predominate, and the freedom that the 2003 reform of the CAP offered farmers to consolidate entitlements established on rented land. The generally very short term nature of Irish agricultural rental contracts offered farmers an opportunity to consolidate entitlements that is unlikely to have arisen in other Member States with agricultural land rental markets characterised by long term contracts. The results in both the pre and post decoupling periods highlight the high degree of inertia of agricultural rents in Ireland, and the importance of accounting for dynamics when investigating the capitalisation of agricultural subsidies into land rents. The high degree of inertia in rents means that the impact of previously capitalised agricultural policy persists through time

Project Nautilus: Lowering the Cost of Oceanic Research

The purpose of this project is to pioneer methods for ocean exploration and documentation so that we might achieve a better understanding of the largest ecosystem in the world: the ocean.The method employed in this project is the construction of an autonomous underwater vehicle with a companion surface vessel. The autonomous function of both of these vehicles will drastically reduce the cost of oceanic research. In cooperation with the university’s mission this project will work to produce the next leaders of the autonomous systems industry through a hands-on approach, with tangible results. Upon completion of this project, Embry-Riddle Aeronautical University will have a rising group of leaders dedicated to the preservation and documentation of the environment through a technological approach. In summation, the purpose of this project is twofold; the creation of a low cost alternative to ocean research and the production of industry leaders

The capitalization of coupled and decoupled CAP payments into land rental rates

This article explores the extent to which payments under the Common Agricultural Policy (CAP) are capitalized into land rents in Ireland with implications for the transfer efficiency of such payments, since subsidies may not benefit targeted recipients if they are capitalized into input prices. Capitalization in the years preceding and following the "decoupling" of agricultural support payments from agricultural production is explored. In the period prior to decoupling, direct support (Pillar 1) payments were highly capitalized into Irish agricultural rents (67-90 cents per euro of subsidies), while in the post-decoupling period capitalization appears to have declined somewhat

Europium-doped barium bromide iodide

Single crystals of Ba0.96Eu0.04BrI (barium europium bromide iodide) were grown by the Bridgman technique. The title compound adopts the ordered PbCl2 structure [Braekken (1932 ▶). Z. Kristallogr. 83, 222–282]. All atoms occupy the fourfold special positions (4c, site symmetry m) of the space group Pnma with a statistical distribution of Ba and Eu. They lie on the mirror planes, perpendicular to the b axis at y = ±0.25. Each cation is coordinated by nine anions in a tricapped trigonal prismatic arrangement

Longitudinal Evaluation of Fatty Acid Metabolism in Normal and Spontaneously Hypertensive Rat Hearts with Dynamic MicroSPECT Imaging

The goal of this project is to develop radionuclide molecular imaging technologies using a clinical pinhole SPECT/CT scanner to quantify changes in cardiac metabolism using the spontaneously hypertensive rat (SHR) as a model of hypertensive-related pathophysiology. This paper quantitatively compares fatty acid metabolism in hearts of SHR and Wistar-Kyoto normal rats as a function of age and thereby tracks physiological changes associated with the onset and progression of heart failure in the SHR model. The fatty acid analog, 123I-labeled BMIPP, was used in longitudinal metabolic pinhole SPECT imaging studies performed every seven months for 21 months. The uniqueness of this project is the development of techniques for estimating the blood input function from projection data acquired by a slowly rotating camera that is imaging fast circulation and the quantification of the kinetics of 123I-BMIPP by fitting compartmental models to the blood and tissue time-activity curves

Testing of the Nursing Evidence‐Based Practice Survey

BackgroundClinicians’ knowledge and skills for evidence‐based practice (EBP) and organizational climate are important for science‐based care. There is scant literature regarding aligning organizational culture with EBP implementation and even less for unit and organizational culture. The Nursing EBP Survey examines individual, unit, and organizational factors to better understand registered nurses’ (RN) self‐reported EBP.AimsEstablish and confirm factor loading, reliability, and discriminant validity for the untested Nursing EBP Survey.MethodsThe study employed a descriptive cross‐sectional survey design and was targeted for RNs. The setting included 14 hospitals and 680 medical offices in Southern California. The 1999 instrument consisted of 22 items; 7 items were added in 2005 for 29 items. The questionnaire used a 5 point, Likert‐type scale. The survey website opened in November 2016 and closed after 23 weeks. Psychometric testing and factor determination used parallel analysis, exploratory factor analysis, confirmatory factor analysis (CFA), and ANOVA post hoc comparisons.ResultsOne thousand one hundred and eighty‐one RNs completed the survey. All factor loadings in the CFA model were positive and significant (p < .001). All standardized loadings ranged from .70 to .94. The covariance estimate between Factor 1 and Factor 2 was marginally significant (p = .07). All other covariances and error variances were significant (p < .001). Final factor names were Practice Climate (Factor 1), Data Collection (Factor 2), Evidence Appraisal (Factor 3), Implementation (Factor 4), and Access to Evidence (Factor 5). Four of 5 factors showed significant differences between education levels (p < .05 level). All factors showed significant differences (p < .05) between inpatient and ambulatory staff, with higher scores for inpatient settings.Linking Evidence to ActionNurses’ knowledge, attitudes, and skills for EBP vary. The 2019 Nursing EBP survey offers RNs direction to plan and support improvement in evidence‐based outcomes and tailors future EBP initiatives.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154968/1/wvn12432.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154968/2/wvn12432_am.pd

Scintillation Properties of Eu2+-Activated Barium Fluoroiodide

The scintillation properties of powders and single-crystals of BaFI doped with Eu2+ are presented. Single crystals were grown by the vertical Bridgman technique. Under optical and X-ray excitation, the samples exhibit a narrow E2+ 5d-4f transition emission centered at 405 nm. The scintillation light output is estimated to be 55,000+-5,000 photons/MeV at 662 keV with 85percent of the light decaying within 600 ns. An energyresolution of 8.5percent full width at half maximum (FWHM) has been achieved using this scintillator for 662 keV excitation (137Cs source) at room temperature
