The Journal of Humanistic Counseling, EarlyView.ABSTRACT This article examines the future place of humanistic counseling, assuming the successful mass deployment of artificial intelligence therapy chatbots (AITCs). We systematically identify the limitations of AITCs through the lens of Jean Baudrillard's view on simulacra and hyperreality and identify five collective psychosocial consequences of ...

Hosoya polynomial, Wiener and Hyper-Wiener indices of some regular graphs
, 2020 Let G be a graph. The distance d(u,v) between two vertices u and v of G is equal to the length of a shortest path that connects u and v. The Wiener index W(G) is the sum of all distances between vertices of G, whereas the hyper-Wiener index WW(G) is ...

Mathematical Methods in the Applied Sciences, EarlyView.We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.

Science Education, EarlyView.ABSTRACT This study examines how integrating sustainability through socio‐scientific issue (SSI) in secondary chemistry teaching shapes epistemic openness and closure from a decolonial perspective, as mediated through classroom discourse. Drawing on a co‐planned lesson on copper mining in Chile – a scientifically rich yet ethically and politically ...

Symbolic Interaction, EarlyView.In the aftermath of the 2020 U.S. election, the boundary between activism and extremism blurred, with election officials reporting violent threats and false accusations of election fraud. From a symbolic interactionist perspective, these attacks provide a unique lens for examining the consequences of being falsely labeled a criminal.

Three Methods for Calculation of the Hyper-Wiener Index of Molecular Graphs [PDF]
Journal of Chemical Information and Computer Sciences, 2002 The hyper-Wiener index WW of a graph G is defined as WW(G) = (summation operator d (u, v)(2) + summation operator d (u, v))/2, where d (u, v) denotes the distance between the vertices u and v in the graph G and the summations run over all (unordered) pairs of vertices of G.

GHOSTLY ENCOUNTERS IN LAGOS: Virtual Reality between Urban Marketing and Media Activism
International Journal of Urban and Regional Research, EarlyView.Abstract This article examines the role of virtual reality (VR) technologies in mediating and contesting dominant visions of urban futures in West Africa. Drawing on theoretical insights from a hybridization of the work of the German‐born Jewish critic Walter Benjamin and the Nigerian writer Amos Tutuola, I introduce the concept of phantasmagoria as a ...

The British Journal of Sociology, EarlyView.ABSTRACT Gender segregation in paid care work offers a critical lens for understanding how gender inequality is reproduced in contemporary societies. While much research has explained men's absence from paid care through cultural and identity‐based accounts, less has been done to examine the structural mechanisms that sustain the feminisation of care ...

Extension of the Wiener index and Wiener polynomial
, 2008 The Wiener index W(G) of a connected graph G is defined as the sum of distances between all pairs of vertices. The Wiener polynomial H(G,x) has the property that its first derivative evaluated at x=1 equals the Wiener index, i.e. H′(G,1)=W(G).
