Production and Operations Management, Volume 31, Issue 12, Page 4599-4615, December 2022., 2022 Abstract Although entrepreneurship‐related papers have had some representation in Production and Operations Management (POM) over the past 30 years, the topic still seems a bit like a poor stepchild in the research of operations management (OM) scholars. Yet, entrepreneurship is important to the economy, and many schools are growing significantly their

Maternal mental health and infant neurodevelopment at 6 months in a low‐income South African cohort
Infant Mental Health Journal: Infancy and Early Childhood, Volume 43, Issue 6, Page 849-863, November 2022., 2022 Abstract Maternal mental health disorders and the adverse consequences for infant neurodevelopment have received substantial research attention in high‐income countries over the past five decades. In Africa, where relatively little work has been done on this topic, researchers have largely focused on infant physical health outcomes.

Exact Solution of Return Hysteresis Loops in One Dimensional Random Field Ising Model at Zero Temperature [PDF]
Phys Rev E62, 4725 (2000)., 2000 Minor hysteresis loops within the main loop are obtained analytically and exactly in the one-dimensional ferromagnetic random field Ising-model at zero temperature. Numerical simulations of the model show excellent agreement with the analytical results.

Conservation of Circulation in Magnetohydrodynamics [PDF]
Phys.Rev. E62 (2000) 5594-5602, 2000 We demonstrate, both at the Newtonian and (general) relativistic levels, the existence of a generalization of Kelvin's circulation theorem (for pure fluids) which is applicable to perfect magnetohydrodynamics. The argument is based on the least action principle for magnetohydrodynamic flow. Examples of the new conservation law are furnished.

Acoustic Energy and Momentum in a Moving Medium [PDF]
Phys.Rev.E62:1341-1350,2000, 1999 By exploiting the mathematical analogy between the propagation of sound in a non-homogeneous potential flow and the propagation of a scalar field in a background gravitational field, various wave ``energy'' and wave ``momentum'' conservation laws are established in a systematic manner.

ECUADOR: LOS DEBATES SOBRE LA SOSTENIBILIDAD DE LA DEUDA Y EL AHORRO PÚBLICO (2001-2019)
Revista de la Facultad de Ciencias Económicas, 2023 El objetivo es exponer los debates alrededor del análisis de la sostenibilidad de la deuda con base en la redefinición del concepto de ahorro público. La investigación está basada en la conceptualización, en la contextualización y en la aplicación de las metodologías convencionales de la sostenibilidad. Bajo esta última se determinó principalmente que:

Duality relations for M coupled Potts models [PDF]
Phys.Rev.E62:1,2000, 2000 We establish explicit duality transformations for systems of M q-state Potts models coupled through their local energy density, generalising known results for M=1,2,3. The M-dimensional space of coupling constants contains a selfdual sub-manifold of dimension D_M = [M/2].
