Whom You Know Matters: Venture Capital Networks and Investment Performance,
- Journal of Finance
, 2007
"... Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

statistically significant, they are also very large economically: IRRs increase by between 11 and 14 percentage points from the 15% sample average for one-standard-deviation increases in indegree and eigenvector. The adjusted R 2 s in all five models are high, ranging from 27.8% for the outdegree specification
Bayesian Detection of Clusters and Discontinuities in Disease Maps
- Biometrics
, 2000
"... An interesting epidemiological problem is the analysis of geographical variation in rates of disease incidence or mortality. One goal of such an analysis is to detect clusters of elevated (or lowered) risk in order to identify unknown risk factors regarding the disease. We propose a nonparametric Ba ..."

within each cluster is unknown. This specification can be seen as a change-point problem of variable dimension in irregular, discrete space. We illustrate our method through an analysis of oral cavity cancer mortality rates in Germany and compare the results with those obtained by the commonly used
Materials for an exploratory theory of the network society.
- The British Journal of Sociology
, 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

in this paper: they rely on data and sources presented in the updated version of my trilogy (Castells 2000a). For the sake of clarity, I will rst present the conceptual framework I use in my analysis of social structure. I will then proceed to enumerate the main transformations taking place in social structures
likelihood and the role of models in molecular phylogenetics.
- Mol. Biol. Evol.
, 2000
"... Methods such as maximum parsimony (MP) are frequently criticized as being statistically unsound and not being based on any ''model.'' On the other hand, advocates of MP claim that maximum likelihood (ML) has some fundamental problems. Here, we explore the connection between the ..."

), the maximum average likelihood tree(s) is precisely the maximum parsimony tree(s). This result, by Tuffley and Steel (1997a), generalizes an earlier special case by The argument used to establish Theorem 2 also shows that, under a Poisson model, if we are given just a tree and a single character (and
Time Reversal FEM Modelling in Thin Aluminium Plates for Defects Detection
"... Abstract. A novel Non Destructive Testing technique for the detection and characterization of defects in thin plate-like structures is presented. When having large structures to be scanned, the use of guided waves is a useful tool to avoid the monitoring of the sample with conventional and very time ..."

Finite Element models using PZFlex have been developed to study the distortion of the TRM signature when appearing cracks in thin
The role of friends' appearance and behavior on evaluations of individuals on Facebook: Are we known by the company we keep?.
- Human Communication Research,
, 2008
"... This research explores how cues deposited by social partners onto one's online networking profile affect observers' impressions of the profile owner. An experiment tested the relationships between both (a) what one's associates say about a person on a social network site via '&a ..."

Statistical analysis of connectivity in unidirectional ad hoc networks
- In Proc. of the International Workshop on Ad Hoc Networking
, 2002
"... A unidirectional link exists in an ad-hoc network when a node B is within the transmission range of another node A while node A cannot directly hear node B. However, a reverse route from B to A might exist, by going through multiple nodes. Unidirectional links may exist in an ad hoc network due to v ..."

topologies employing two models and study the connectivity of the sub-graphs formed by including unidirectional links of different reverse-route lengths. We observe from this analysis that the connectivity has a heavy-tail distribution and that using only bidirectional links could cause partitions
Modeling the hemodynamic response function in fMRI: efficiency, bias and mis-modeling. Neuroimage
, 2009
"... Most brain research to date have focused on studying the amplitude of evoked fMRI responses, though there has recently been an increased interest in measuring onset, peak latency and duration of the responses as well. A number of modeling procedures provide measures of the latency and duration of f ..."

The dominant analysis strategy is to assume that BOLD responses to events add linearly Choices of HRF models range from the use of a single canonical HRF, the use of a basis set of smooth functions Thus, in sum, the nature of the underlying BOLD physiology limits the ultimate
