The concept and experience of community have been changing in contemporary societies, from a traditional an idealistic, homogeneous context, characterized by union, to the exploration new forms organization participation. specific characteristics dynamics emerging video game (VG) communities can help us better understand importance cultures. Based on ethnographic study five jams data eight focu...

To achieve net-zero emissions economy, the transition to online entertainment and retail, aging populations, urban population growth, pressures on public finance have created huge interests for human run cities differently smartly. A term titled smart city is which considered as an idealistic city, where quality of life citizens greatly improved by utilizing information communication technology...

Below let II = [0, 1]. A well-known topological theorem due to Katětov states: Suppose (X, τ) is a normal topological space, and let f : X → II be upper semicontinuous, g : X → II be lower semicontinuous, and f ≤ g. Then there is a continuous h : X → II such that f ≤ h ≤ g. Recall that f : X → II is upper semicontinuous if f is continuous from (X, τ) to (II, ω); lower semicontinuous if continuo...

Kummer, M. and F. Stephan, Weakly semirecursive sets and r.e. orderings, Annals of Pure and Applied Logic 60 (1993) 133-150. Weakly semirecursive sets have been introduced by Jockusch and Owings (1990). In the present paper their investigation is pushed forward by utilizing r.e. partial orderings, which turn out to be instrumental for the study of degrees of subclasses of weakly semirecursive s...

In this paper we prove the existence and upper semicontinuity of compact global attractors for the flow of the equation ∂u(x, t) ∂t = −u(x, t) + J ∗ (f ◦ u)(x, t) + h, h ≥ 0, in L weighted spaces.

This article extends and expands a nuanced unpacking of conceptualisations critical global citizenship education (GCE) in typologies GCE (Pashby, K., M. da Costa, S. Stein, V. Andreotti. [2020]. “A meta-review education.” Comparative Education 56 (2): 144–164.). It finds approaches to can be described broad terms that conflate quite distinct agendas; critiqued as unpragmatic, idealistic, morall...

We prove that every multi-player perfect-information game with bounded and lower-semi-continuous payoffs admits a subgame-perfect ε-equilibrium in pure strategies. This result complements Example 3 in Solan and Vieille (2003), which shows that a subgame-perfect ε-equilibrium in pure strategies need not exist when the payoffs are not lower-semi-continuous. In addition, if the range of payoffs is...
