We propose a novel method of community detection that is computationally inexpensive and possesses physical significance to a member of a social network. This method is unlike many divisive and agglomerative techniques and is local in the sense that a community can be detected within a network without requiring knowledge of the entire network. A global application of this method is also introdu...

Abstract After WWII, the demographic transition exhibited features of convergence between developing countries and forerunner with low fertility. Although today fertility is in majority countries, significant differences persist. In this article, I study club 190 over period 1950 to 2018. First, apply a novel econometric method for analysis clustering. find no evidence global convergence, class...

Low-carbon economic development is at the heart of post-pandemic green recovery scheme worldwide. It requires without compromising on environment, implying a critical role that productivity plays in achieving carbon neutrality goal. Green measures quality growth with consideration for energy consumption and environmental pollution. This study employs slacks-based measure directional distance fu...

We reassess the convergence properties of the cross-country distribution of income and its determinants using the dataset constructed by Klenow and Rodriguez-Clare (2005) and our updated version of the same data. Consistent with the literature, the ergodic distribution of output per worker features separate convergence clubs. In contrast to previous …ndings, productivity display convergence in ...

The paper investigates cross-country differences in technology in a large sample of developed and developing economies over the 1990s. The empirical analysis indicates the existence of three technology clubs with markedly different levels of technological development: advanced, followers and marginalized countries. The technology clubs also differ with respect to their dynamics over the 1990s. ...

In birds and other vertebrates, most acoustic signals are produced pneumatically by moving air through a vocal apparatus. Here we describe a unique mechanism used to produce a tonal acoustic signal in vertebrates. Video recordings of the courtship displays of male Club-winged Manakins, Machaeropterus deliciosus, reveal that males produce sustained harmonic tones through interactions among oscil...

One of the recent strategies for increasing the customer’s loyalty in banking industry is the use of customers’ club system. In this system, customers receive scores on the basis of financial and club activities they are performing, and due to the achieved points, they get credits from the bank. In addition, by the advent of new technologies, fraud is growing in banking domain as well. Therefor...

In this note, we discuss the convergence behavior of a modified inexact Uzawa algorithm for solving generalized saddle point problems, which is an extension of the result obtained in a recent paper [Z.H. Cao, Fast Uzawa algorithm for generalized saddle point problems, Appl. Numer. Math., 46 (2003) 157-171]. Keywords—Saddle point problem; Inexact Uzawa algorithm; Convergence behavior.

In this paper, we prove a strong convergence result using a recently introduced iterative process with contractive-like operators. This improves andgeneralizes corresponding results in the literature in two ways: iterativeprocess is faster, operators are more general. At the end, we indicatethat the results can also be proved with the iterative process witherror terms. Keywords—Contractive-like...
