nnovativeness nowledge heterogeneity etwork structure Structural holes theory suggests a variety of possible explanations for the empirically observed relationship between structural holes and individual managerial performance. However, little has been done to disentangle onemechanism fromanother. This paper empirically tests amediatedmoderationmodel that distinguishes between the five differen...

The present study examined the components of end of kindergarten writing, using data from 242 kindergartners. Specifically of interest was the importance of spelling, letter writing fluency, reading, and word- and syntax-level oral language skills in writing. The results from structural equation modeling revealed that oral language, spelling, and letter writing fluency were positively and uniqu...

Examination of functional interactions through effective connectivity requires the determination of three distinct levels of information: (1) the regions involved in the process and forming the spatial support of the network, (2) the presence or absence of interactions between each pair of regions, and (3) the directionality of the existing interactions. While many methods exist to select regio...

As the number of complete genomes that have been sequenced keeps growing, unknown areas of the protein space are revealed and new horizons open up. Most of this information will be fully appreciated only when the structural information about the encoded proteins becomes available. The goal of structural genomics is to direct large-scale efforts of protein structure determination, so as to incre...

We specify here the features which are used by our models. Each feature description is composed of two parts: a description of a structural element, and a (possibly empty) description of a sequential context. All models discussed in the paper are obtained by combining a set of structural elements St with a set of sequential contexts Co, and producing all corresponding features (i.e. producing a...

Evaluating overall model fit for growth curve models involves 3 challenging issues. (a) Three types of longitudinal data with different implications for model fit may be distinguished: balanced on time with complete data, balanced on time with data missing at random, and unbalanced on time. (b) Traditional work on fit from the structural equation modeling (SEM) perspective has focused only on t...

Purpose – Organizational performance, growth and development may depend considerably on entrepreneurship in existing organizations (intrapreneurship) and intrapreneurship employee-related antecedents. The purpose of this study is to focus on employee satisfaction (composed of four dimensions: general satisfaction with work; employee relationships; remuneration, benefits and organizational cultu...

PURPOSE Lack of control for time-varying exposures can lead to substantial bias in estimates of treatment effects. The aim of this study is to provide an overview and guidance on some of the available methodologies used to address problems related to time-varying exposure and confounding in pharmacoepidemiology and other observational studies. The methods are explored from a conceptual rather t...
