The spectral properties of the adjacency matrix, in particular its largest eigenvalue and the associated principal eigenvector, dominate many structural and dynamical properties of complex networks. Here we focus on the localization properties of the principal eigenvector in real networks. We show that in most cases it is either localized on the star defined by the node with largest degree (hub...

Can activation requirements control moral hazard problems in public sickness absence insurance and accelerate recovery? Based on empirical analysis of Norwegian data, we show that it can. Activation requirements not only bring down benefit claims, they also reduce the likelihood that long-term sickness absence leads to inactivity. Our findings show that absentees who are issued graded (partial)...

ion Sheets unterstützen die genaue Analyse eines Ziels [vSB99]. Sie dienen insbesondere als Kommunikationsmittel zwischen den Beteiligten. In einem Abstraction Sheet werden die folgenden Elemente erfasst: • von den Projektbeteiligten vorgeschlagene Metriken, um die Zielerreichung zu messen, • eine Hypothese über die erwarteten Ergebnisse, • mögliche Ein ussfaktoren auf das Ergebnis in dem betra...

Sublingual immunization, where the vaccine is placed directly under the tongue and absorbed through the sublingual mucosa, has the advantages of ease of delivery without the complication of oral administration or the safety concerns of intranasal vaccines. Sublingual vaccine delivery has been shown to induce development of humoral and cell mediated immunity in both the systemic and mucosal comp...

OBJECTIVE A study was conducted to test six threonine (Thr) levels (0.39%, 0.44%, 0.49%, 0.54%, 0.59%, and 0.64%) to estimate the optimal dietary Thr requirements for Longyan laying ducks from 17 to 45 wk of age. METHODS Nine hundred Longyan ducks aged 17 wk were assigned randomly to the six dietary treatments, where each treatment comprised six replicate pens with 25 ducks per pen. RESULTS...

Recent studies have revealed that emotional competences are relevant to the student's learning process and, more specifically, in the use of learning strategies (LSs). The aim of this study is twofold. First, we aim to analyze the relationship between perceived emotional intelligence (PEI) and LSs applying the scales TMMS-24 and Abridged ACRA to a sample of 2334 Spanish university students, whi...
