Connectedness classes
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: G. CastelliniLet X be an (E,M)-category for sinks. A recently introduced notion of connectedness with respect to a closure operator C on X and to a class of X-monomorphisms N is further analyzed. The notion of N-connectedness hull of a class... -

D-connectedness
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Kim-Quang TranThe aim of this paper is to study the categorical topological notion of connectedness in terms of a rather arbitrary class of morphisms in a category.

T 1-separation in a category
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: G. CastelliniA general notion of T 1-separation with respect to a closure operator is introduced in an arbitrary category. This is done by specializing a previously introduced diagram of Galois connections. This naturally yields a dual notion of T 1-coseparation. These... -
Approach structures and measures of connectedness
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: David Holgate Mark SioenMeasures of connectedness versus disconnectedness are introduced in anarbitrary topological construct as fixed points of a Galois connection.

SPREAD UNIFORMITIES AND UNIFORM SPREADS
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Hlengani Slweya --- Department of Mathematics, University of the North, Sovenga, South Africa,We discuss a point-free analog of the topological fact that every uniformly continuous function on a dense subspace of a uniform space into a complete uniform space has a unique uniformly continuous extension. It is shown that a uniform frame... -
Interior Operators and Topological Connectedness
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: G. Castellini --- Department of Mathematical Sciences, U.S.A. J. Ramos --- Department of Mathematical Sciences, U.S.A.A categorical notion of interior operator is used in topology to define connectedness and disconnectedness with respect to an interior operator. A commutative diagram of Galois connections is used to show a relationship between these notions and Arhangelskii and Wiegandt's... -
Discrete Objects, Splitting Closure and Connectedness
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Gabriele CastelliniNotions of discrete and indiscrete classes with respect to a closure operator are introduced and studied. These notions are strongly related to splitting and cosplitting closure operators. By linking the above concepts, two Galois connections arise whose composition provides a... -

Indigenizing counselling valuing the afterlife with the Igbo of south eastern Nigeria: a case for ino-uwa based intervention
Item type: Journal Article • Journal: Journal of Psychology in Africa • Authors: Chika Eze --- Department of Psychology, Faculty of Education, KenyaThis study examines prospects for the utilization of the concept of ino-uwa practised by the Igbo cultural-linguistic community of South Eastern Nigeria to understand and address counselling needs of a child and his family. Ino-uwa is the cultural familial scaffold... -
Time dynamics of connectedness between commodity convenience yields and zero-coupon inflation swap rates
Item type: Journal Article • Journal: Investment Analysts Journal • Authors: Okan Aybar --- , France Mehmet Huseyin Bilgin --- , Turkey Serda Selin Öztürk --- , TurkeyGlobalisation and financial liberalisation have made financial markets more correlated and connected. In this context, it has become extremely important to understand the connectedness and correlation among different financial markets and commodities. This paper attempts to extend applicable empirical studies... -
Is the rand a commodity currency? A volatility spillover analysis
Item type: Journal Article • Journal: Investment Analysts Journal • Authors: Ayesha Sayed --- , South Africa Ailie Charteris --- , South AfricaSouth Africa is a major commodity exporter, yet it is not clear what impact volatility in commodity prices has on the volatility of its currency. In this study, we examine whether a comprehensive sample of commodities (metals, grains and energy)... -
