Situating peace journalism in journalism studies: A critical appraisal [PDF]
Conflict & Communication Online, 2007 Most wars were not brought to our attention if there were no journalists to report on them and no news media to send reporters to conflict spots. At the same time, the media often give priority to conflict and war at the expense of playing a positive ...

Modular networks emerge from multiconstraint optimization [PDF]
, 2007 Modular structure is ubiquitous among complex networks. We note that most such systems are subject to multiple structural and functional constraints, e.g., minimizing the average path length and the total number of links, while maximizing robustness ...

Structural Topology Optimization with Local Finite-Life Fatigue Constraints
Mathematics, 2023 To improve the fatigue resistance of engineering structures, topology optimization has always been an effective design strategy. The direct calculation of large-scale local fatigue constraints remains a challenge due to high computational cost.

APPLICATION OF GRADIENT PROJECTION METHOD TO PARAMETRIC OPTIMIZATION OF STEEL LATTICE PORTAL FRAME
International Journal for Computational Civil and Structural Engineering, 2021 The paper has proposed a mathematical model for parametric optimization problem of the steel lattice portal frame. The design variable vector includes geometrical parameters of the structure (node coordinates), as well as cross-sectional dimensions of ...

Image completion via transformation and structural constraints
EURASIP Journal on Image and Video Processing, 2020 Image completion is an approach to fill a damaged region (hole) in an image. In this study, we adopt a novel method which can repair a target region with structural constraints in an architectural scene. An objective function that consists of three terms

Structural Decompositions for Problems with Global Constraints
, 2015 A wide range of problems can be modelled as constraint satisfaction problems (CSPs), that is, a set of constraints that must be satisfied simultaneously.

In defense of peace journalism: A rejoinder [PDF]
Conflict & Communication Online, 2007 The following is a contribution to the ongoing debate about the merits and demerits of peace journalism. The writer, a proponent of the new philosophy, answers Loyn's and Hanitzsch's attacks by claiming that peace journalism has enough of novel insights ...

Effects of N-cadherin disruption on spine morphological dynamics
Frontiers in Cellular Neuroscience, 2007 Structural changes at synapses are thought to be a key mechanism for the encoding of memories in the brain. Recent studies have shown that changes in the dynamic behavior of dendritic spines accompany bidirectional changes in synaptic plasticity, and ...
