Power expansions for solution of the fourth-order analog to the first Painlev\'{e} equation

, 2005
One of the fourth-order analog to the first Painlev\'{e} equation is studied. All power expansions for solutions of this equation near points $z=0$ and $z=\infty$ are found by means of the power geometry method. The exponential additions to the expansion

Sustainability as Justice: Making the “Leave No One Behind” Work

Sustainable Development, EarlyView.
ABSTRACT This paper critically engages with the LNOB principle of the 2030 Agenda, highlighting its conceptual, methodological, and structural limitations. Building on Amartya Sen's social choice theory and Rawlsian justice, it reconceptualizes “sustainability as justice,” emphasizing real‐world comparative assessments grounded in intersectionality. It

Exact Mathematical Solution for Maximum Transient Offtracking Calculation of a Single-Unit Vehicle Negotiating Circular Curves

Applied Sciences
The low-speed turning maneuverability of vehicles is closely related to a well-known offtracking phenomenon which occurs when the rear wheels of a turning vehicle deviate towards the inside of a horizontal curve. Although numerous mathematical models and

On the one-dimensional reggeon model: eigenvalues of the Hamiltonian and the propagator

European Physical Journal C: Particles and Fields, 2019
The effective reggeon field theory in zero transverse dimension (“the toy model”) is studied. The transcendental equation for the eigenvalues of the Hamiltonian of this theory is derived and solved numerically.

Vlasov tokamak equilibria with shearad toroidal flow and anisotropic pressure

, 2015
By choosing appropriate deformed Maxwellian ion and electron distribution functions depending on the two particle constants of motion, i.e. the energy and toroidal angular momentum, we reduce the Vlasov axisymmetric equilibrium problem for quasineutral ...

Was the Inca Economy Based on “Protomoney”? Or, Why Accounting Systems Should Not Be Conflated With Concepts of Exchange Value

Economic Anthropology, EarlyView.
ABSTRACT The khipu knotted string records in the ancient Andes were accounting systems, but they did not indicate any concepts of commensurability or exchange value. They were not incipient money; instead, monetized commerce appears to have predated the economic organization of the Inca society. The article begins by tracing the emergence of coinage in

Who Is the System? On the Externalisation and Depersonalisation of Responsibility for Abuse

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This article examines the externalisation and depersonalisation of responsibility in the institutional communication of the Roman Catholic Church in the context of sexualised violence. Niklas Luhmann's theory of social systems is used to show how semantic constructions such as ‘systemic causes’ rhetorically blur responsibility and contribute ...

Analytic solutions of $q$-$P(A_1)$ near its critical points

, 2016
For transcendental functions that solve non-linear $q$-difference equations, the best descriptions available are the ones obtained by expansion near critical points at the origin and infinity.

The transcendental Risch differential equation

Journal of Symbolic Computation, 1990
Let \(k\) be a differential field of characteristic \(0\) and \(K\) be a differential field extension of \(k\) (with derivation \(x\mapsto x': K\to K\)); let \(\theta\) be an element of \(K\) satisfying the following conditions: \(\theta\) is transcendental over \(k\), \(k\) and \(k(\theta)\) have the same field of constants, and either \(\theta\) is ...

The History and Ideas of George Herbert Mead's Pragmatism and Its Relevance for Operational Research and Systems Thinkers

Systems Research and Behavioral Science, EarlyView.
ABSTRACT George Herbert Mead is an oft forgotten or ignored American philosopher who was one of the originators of pragmatism. Today, he is recognised as a creative thinker who has teased out knotty problems that others in the field had not realised were problems. Understanding Mead's analysis has been made difficult because he died prematurely without
