Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Firm turnover under asymmetric information: Tanzania's agro‐dealer sector

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract We study firm turnover (i.e., entry and exit) and its consumer implications in a market characterized by asymmetric information. Using a three‐round census of agro‐dealers in Tanzania's Morogoro Region, we document annual firm entry and exit rates of 33% and 17%, respectively.

On some inequalities for the matrix power and Karcher means

open access: yesLinear Algebra and its Applications, 2013
The authors have establish a useful inequality for matrix power means of positive definite matrices. The paper provides a simple proof of the convergence of power means to the Karcher mean. Some new matrix mean inequalities on the Karcher and power means are presented.

The psychosocial toll of Dublin III on asylum seekers in the Netherlands

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract The Dublin III Regulation determines which EU Member State is responsible for examining asylum claims, but its implementation carries significant consequences for those subjected to it. This study examines how Dublin III, as implemented in the Netherlands, affects asylum seekers' psychosocial wellbeing using Silove′s Adaptation and Development

Norm inequalities for weighted power means of operators

open access: yesLinear Algebra and its Applications, 2002
Let \(A_{i}\), \(X_{i}\) and \(Y_{i}\) be bounded linear operators on a Hilbert space for \(i=1,2,\dots ,n\). In the present paper, the authors prove the following norm inequalities: (i) If \(\sum_{i=1}^{n}X^{*}_{i}X_{i}\leq I\), \(\sum_{i=1}^{n}Y^{*}_{i}Y_{ i}\leq I\) and \(r\geq 1\), then \[ \Bigg|\Bigg|\Bigg|\Bigg |\sum_{i =1}^{n} X_{i}^{*}A_{i}Y_{i}

Border harm and affective injustice: The politics of anger at the Melilla border, Spain

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This article examines protests in a detention center in Melilla, Spain—a site where structural violence intersects with the everyday harms of confinement. Adopting a justice and dignity‐centered perspective, we analyze grassroots forms of resistance emerging at the border. The study focuses on the protests of Tunisian migrants and explores the

New Quantum Estimates of Trapezium-Type Inequalities for Generalized ϕ-Convex Functions

open access: yesMathematics, 2019
In this paper, a quantum trapezium-type inequality using a new class of function, the so-called generalized ϕ -convex function, is presented. A new quantum trapezium-type inequality for the product of two generalized ϕ -convex functions is ...

Negotiating contested spaces and places: Narratives of social suffering and resistance in racialized Cape Town communities

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This study employs a schizocartographic approach to explore community narratives of space, memory, and violence in Kraaifontein, Cape Town. Through participants' accounts, ordinary places—gardens, shops, blocks, sports grounds, and streets—emerge as ambivalent geographies where trauma, resilience, and belonging intersect.

Matrix power means and Pólya-Szegő type inequalities

open access: yesSurveys in Mathematics and its Applications, 2020
Summary: It is shown that, if \(\mu\) is a compactly supported probability measure on \(\mathbb{M}^+_n\), then, for every unit vector \(\eta\in\mathbb{C}^n\), there exists at compactly supported probability measure (denoted by \(\langle\mu\eta,\eta\rangle)\) on \(\mathbb{R}^+\) so that the inequality \[\langle P_t(\mu)\eta,\eta\rangle\le P_t(\langle\mu
