On Liouville-type theorems for k-Hessian equations with gradient terms

, 2023
In this thesis, we examine solutions/sub-solutions to k-Hessian equations with gradient terms on all of Rn. We show under specific conditions when such equa-tions admit only trivial solutions, as well as when such solutions are nontrivial.

Take Me Home, Country Roads: Choosing Autonomous EVs Over Personal Aviation

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper investigates the potential long‐run effects of autonomous and electric vehicles, and a carbon tax, on personal domestic aviation demand in Australia. We estimate a discrete choice disutility model with two travel modes—car and air—using Australian National Visitor Survey data and Bayesian priors. We use multiplicative Fréchet errors,

Doubling Argument of the Hessian Estimate for the Hessian Quotient Equations

In this paper, we establish a doubling argument to obtain Hessian estimates for convex solutions to the Hessian quotient equation $\frac{σ_n}{σ_k}(D^2u) = f(x,u,Du)$ for $k=n-1$ and $k=n-2$ under the condition that $\log f$ is convex in the $Du$ variable.

The Road to Nowhere: Being Rooted in a Region Does Little to Predict Support for Populist Parties or Opposition to Migration and Social Change

The British Journal of Sociology, EarlyView.
ABSTRACT In his influential book The road to somewhere David Goodhart claims that a split between a majority of people who are rooted in particular places or groups (the “Somewheres”) and a minority of people who are or can be at home anywhere in the world (the “Anywheres”) is at the heart of many contemporary political conflicts. According to him, the

From allostasis to addiction: Cortisol dysregulation, daily stress and relations with 9‐year alcohol and substance use disorder severity in community adults

Addiction, EarlyView.
Abstract Background and aims Diurnal cortisol dysregulation and daily stressor severity may jointly forecast long‐term alcohol use disorder (AUD) and substance use disorder (SUD) severity, yet most evidence is cross‐sectional and relies on single cortisol indices.

Existence of solutions with asymptotic behavior of exterior problems of Hessian equations

, 2011
In this paper, we use the Perron method to prove the existence of viscosity solutions with asymptotic behavior at infinity to Hessian equations.

Beyond profit maximization: The effect of cooperative governance on insolvency risk in the Brazilian supplementary healthcare industry

Annals of Public and Cooperative Economics, EarlyView.
Abstract Traditional bankruptcy literature has primarily focused on commercial enterprises, often overlooking the unique dynamics of cooperatives and other small organizations. This study addresses this g ap by developing a predictive model for insolvency risk within Brazil's supplementary health sector, encompassing both for‐profit and not‐for‐profit ...

Differential item functioning detection across multiple groups

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Differential item functioning (DIF) can be investigated by estimating item response theory (IRT) parameters separately for different respondent groups, thus allowing for the detection of discrepancies in parameter estimates across groups. However, before comparing the estimates, it is necessary to convert them to a common metric due to the ...

LLM‐based prior elicitation for Bayesian graphical modeling

British Journal of Mathematical and Statistical Psychology, EarlyView.
ABSTRACT In the Bayesian graphical modeling framework, priors on network structure encode theoretical assumptions and uncertainty about the topology of psychological constructs under study. For instance, the Bernoulli prior specifies the probability of each pairwise interaction, the Beta–Bernoulli prior governs expected network density, and the ...
