Resolving Structure in Human Brain Organization: Identifying Mesoscale Organization in Weighted Network Representations
Human brain anatomy and function display a combination of modular and
hierarchical organization, suggesting the importance of both cohesive
structures and variable resolutions in the facilitation of healthy cognitive
processes. However, tools to simultaneously probe these features of brain
architecture require further development. We propose and apply a set of methods
to extract cohesive structures in network representations of brain connectivity
using multi-resolution techniques. We employ a combination of soft
thresholding, windowed thresholding, and resolution in community detection,
that enable us to identify and isolate structures associated with different
weights. One such mesoscale structure is bipartivity, which quantifies the
extent to which the brain is divided into two partitions with high connectivity
between partitions and low connectivity within partitions. A second,
complementary mesoscale structure is modularity, which quantifies the extent to
which the brain is divided into multiple communities with strong connectivity
within each community and weak connectivity between communities. Our methods
lead to multi-resolution curves of these network diagnostics over a range of
spatial, geometric, and structural scales. For statistical comparison, we
contrast our results with those obtained for several benchmark null models. Our
work demonstrates that multi-resolution diagnostic curves capture complex
organizational profiles in weighted graphs. We apply these methods to the
identification of resolution-specific characteristics of healthy weighted graph
architecture and altered connectivity profiles in psychiatric disease.Comment: Comments welcom

D’une analyse de variabilités à un modèle d’investissement des firmes
Nous introduisons une approche du général au spécifique adaptée à des données de panel. Ceci conduit à considérer des décompositions en valeurs singulières menées à partir d’équations d’analyse de la variance multivariées faisant apparaître les effets individuels et temporels. Nous utilisons cette méthodologie pour analyser la présence de contraintes de liquidité comme déterminant de l’investissement des firmes canadiennes.We introduce a general to specific approach suitable for panel data. We are led to perform singular value decompositions based on a multivariate variance analysis equation, in which the individual and time effects are explicitely taken into account. This methodology is applied to the analysis of liquidity constraints as a determinant of corporate investment in Canada
Establishing a Review Process to Evaluate Research Guides
Springshare\u27s LibGuide platform has become synonymous with online library pathfinders or research guides and instruction support. However, without oversight of the collection of guides and standards for their creation, unwieldy numbers and lack of uniformity prevail. The McGoogan Library of Medicine at the University of Nebraska Medical Center created a review process that not only governed the creation and approval of guides, but analyzed the usage and scope of guides that had already been created. This paper will outline the creation of standards and application of a review process to increase the value and relevance of guides

Waterbird Population Dynamics in the Middle Mahakam Wetlands of East Kalimantan over 23 years
Between 1988 and 2011, a total of 57 species of waterbirds, as well as twelve raptor and six kingfisher species regularly utilizing wetlands, were recorded in the Middle Mahakam Wetlands of East Kalimantan, Indonesia. Waterbirds included 27 shorebird species from five families, twelve herons (Ardeidae), six rails and crakes (Rallidae), four terns (Sternidae), three ducks (Anatidae) and two storks (Ciconiidae). Based on IUCN (2013) criteria, six listed species are threatened: one (White-shouldered Ibis) is Critically Endangered, another (Storm's Stork) is Endangered and four (Chinese Egret, Lesser Adjutant, Wallace's Hawk-Eagle, Blue-banded Kingfisher) are Vulnerable. The Middle Mahakam Wetlands are one of Borneo’s most important wetland areas. They are part of a highly dynamic landscape that has historically changed its appearance many times. Today, the birds of these unique wetlands are endangered by a plethora of threats comprising large scale land conversion, fire, hunting and live capture of waterbirds, illegal logging and pollution. Despite the considerable efforts of local NGOs to address some of these issues, conservation measures are still limited and insufficient to protect this natural asset
Development of New Business Models: Introducing the Cultural Elasticity Model
The paper presents the Cultural Elasticity Model as a new perspective on how existing companies may better perform continuous organic development of business models. It suggests three organisational pillars for the development of an organisation with strong cultural elasticity and therefore the ability to better innovate new business models
