‘Why Did You Go to Buda?’: The Humanist Sodality and Mantuan’s Rustic Idyll in Bohuslaus of Hassenstein’s Ecloga sive Idyllion Budae (1503)☆

Renaissance Studies, EarlyView.
Abstract In the late fifteenth century, the Hungarian royal court at Buda was home to a cosmopolitan community of humanists. In early modern historiography, this cultural milieu has often been interpreted as one of the new, emergent ‘centres’ of the Renaissance in East Central Europe.

Does Japanʼs Aid Promote the Economic Growth of Pacific Island Countries?

Asia &the Pacific Policy Studies, Volume 13, Issue 3, September 2026.
ABSTRACT Pacific Island countries (PICs) are among the worldʼs most aid‐dependent nations. This study examines relations between Japanʼs aid and the economic growth of 13 PICs during 2000–2023. After evaluating overall effects of Japanʼs aid, specific types are analysed: economic, social, production, and multi‐sector aid.

“We Have to Find What We're Doing Right to Move Forward”: Enacting Secondary Level Writing Reform in a Sea of Change

Journal of Adolescent &Adult Literacy, Volume 70, Issue 1, July/August 2026.
ABSTRACT Despite calls for writing reform over the past two decades, few of the recommendations from this work have made their way into high school classrooms in the United States where concerns about the paucity and quality of writing instruction remain.

A simple method for controlling buck-boost SEPIC H-bridge inverter

Over the past decade, much research and development has gone into the use of electric power converters, and the trend is upward. Inverters are employed when converting DC voltage to AC voltage. Typically, inverters perform functions such as voltage boost

Brain Drain and Productivity Growth: Evidence From South Africa, 1947–2019

Economics of Transition and Institutional Change, Volume 34, Issue 3, Page 605-631, July 2026.
ABSTRACT This paper provides empirical evidence of how high‐level human capital outflow could affect TFP‐based economic development and vice versa. The concern of potential endogeneity between brain drain and economic development is addressed directly.
