Was Ireland better off in 1994 than in 1987? [PDF]

open access: yes
This paper examines the change in welfare in Ireland over the 1987- 1994 period by investigating whether Lorenz and Generalised Lorenz dominance can be observed for household expenditure data.

Isoelectronic Alloying in Zintl Phases Mediated the Avoided Crossing and Phonon Softening

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A small amount of Hf doping endows Zr3Ni3Sb4‐Zintl with an unusually low thermal conductivity far exceeding that of similar systems. Two unique phonon mechanisms—avoided crossing and phonon softening—significantly suppress the lattice thermal conductivity. The average thermoelectric figure of merit is improved by 21%.

Increasing Student Teachers' Preference of Scientific Evidence—Insights From a Utility Value Intervention

open access: yesFuture in Educational Research, EarlyView.
ABSTRACT Teacher education should equip student teachers with scientific evidence and scientific theories as a resource for future pedagogical action. In opposition to this, student teachers tend to perceive a rather low utility value of scientific evidence and scientific theories for pedagogical action.

Electricity Price Prediction Using Multikernel Gaussian Process Regression Combined With Kernel‐Based Support Vector Regression

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT This paper presents a new hybrid model for predicting German electricity prices. The algorithm is based on a combination of Gaussian process regression (GPR) and support vector regression (SVR). Although GPR is a competent model for learning stochastic patterns within data and for interpolation, its performance for out‐of‐sample data is not ...

Leveraging Machine Learning to Predict Food Waste Quantity: Focusing on Military Dining Facilities as Large‐Scale Food Service Operations

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Food waste reveals inefficiencies in resource use and contributes significantly to environmental pollution. In the United States, food waste accounts for the majority of total waste, with more than 50 million tons generated annually. In military units that operate large‐scale institutional food‐service facilities and generate significant food ...

Bifurcation analysis and dynamics of a Lorenz –type dynamical system

open access: yesپژوهش‌های ریاضی, 2017
./files/site1/files/0Abstract1.pdfIn this paper we consider a continues Lorenz – type dynamical system. Dynamical behaviors of this system such as computing equilibrium points, different bifurcation curves and computation of normal form coefficient of ...

REVISITING THE ORDERED FAMILY OF LORENZ CURVES [PDF]

open access: yes
Lorenz curve; Gini index Abstract: Sarabia et al. (1999) present a basic model to create ordered families of Lorenz curves, along with basic theorems that describe the conditions for the models to satisfy the definition of the Lorenz curve.

Competing Demographic Drivers of Hospital Expenditures: Coexistence of the Red Herring and the Steepening Effects

open access: yesHealth Economics, EarlyView.
ABSTRACT The fiscal sustainability of healthcare systems is increasingly strained by aging populations with two competing hypotheses dominating the literature. The Red Herring Hypothesis suggests that healthcare expenditures are driven more by proximity to death than by chronological age, while the Steepening Hypothesis examines whether expenditures ...
