Graph manipulations for fast centrality computation [PDF]

, 2014
The betweenness and closeness metrics have always been intriguing and used in many analyses. Yet, they are expensive to compute. For that reason, making the betweenness and closeness centrality computations faster is an important and well-studied problem.

Efficient Exact and Approximate Algorithms for Computing Betweenness Centrality in Directed Graphs

, 2017
Graphs are an important tool to model data in different domains, including social networks, bioinformatics and the world wide web. Most of the networks formed in these domains are directed graphs, where all the edges have a direction and they are not ...

Sleep disturbance as a transdiagnostic marker of children's mental health difficulties: A network analysis of item‐level associations between different types of sleep problems and different behavioural and emotional symptoms

JCPP Advances, EarlyView.
Abstract Background Sleep disturbances are widely considered to be a transdiagnostic feature of common behavioural and emotional difficulties in childhood, yet most studies treat sleep as a single construct. Where studies have explored specific sleep problems to psychopathology in children, these tend to only include behavioural or emotional ...

The dynamics of closeness and betweenness [PDF]

Although both betweenness and closeness centrality are claimed to be important for the effectiveness of someones network position, it has not been explicitly studied which networks emerge if actors follow incentives for these two positional advantages ...

Harnessing personal and social resources in managing internalising and externalising symptoms in children living in low‐resource settings

JCPP Advances, EarlyView.
Abstract Background Children growing up in low‐resource settings are at greater risk for lifelong psychiatric problems. They are both more likely to have risk factors for early psychopathology and to be less likely to seek help and engage support for these problems.

Temporal betweenness centrality on shortest walks variants

Applied Network Science
Betweenness centrality has been extensively studied since its introduction in 1977 as a measure of node importance in graphs. This measure has found use in various applications and has been extended to temporal graphs with time-labeled edges.

Transdiagnostic symptom networks in adolescent psychopathology: A longitudinal panel network analysis

JCPP Advances, EarlyView.
Abstract Background Understanding symptom patterns of emerging psychopathology is essential for early detection and intervention. Network analysis offers a promising approach by conceptualizing emerging psychopathology as dynamic interactions between symptoms over time.

North–South Asymmetries in Research Cited in Global South Policy Documents

Journal of International Development, EarlyView.
ABSTRACT This article examines whose research is cited in economy‐related policy documents produced by organizations in countries of the Global South. Using Overton's Economy topic, we link 243 675 policy documents from 155 Global South countries to 68 550 Web of Science articles cited in those documents.

A Framework for Subgroup Dynamics Through the System Dynamics Lens: An Integrative Review of the Attribute and the Network Views

Journal of Organizational Behavior, EarlyView.
ABSTRACT Subgroups are dynamic entities evolving constantly in response to changing contexts and time. Although scholars from both the attribute and the network views have acknowledged that subgroups are inherently complex and fluid, research in these traditions has remained bifurcated, with limited efforts to integrate the two perspectives to more ...

The Relational Dimension in Gestalt Psychotherapy: Epistemological and Clinical Aspects

The Journal of Humanistic Counseling, EarlyView.
ABSTRACT This article reframes Gestalt psychotherapy as intrinsically relational: experience and self‐emerge from contact at the organism–environment boundary and from the field/situation. We revisit ambiguities in the Perls/Goodman model against a brief historical background and articulate a pragmatic stance grounded in the id of the situation and ...
