Market Orientation and Degree of Novelty

This study aims to examine the relationship between a responsive and a proactive market orientation and the degree of novelty. Data obtained via an Internet survey were analysed using structural equation modelling. An analysis of 325 Slovenian firms reveals that only a proactive market orientation is positively related to the degree of novelty. While there is no evidence of statistically significant differences in the examined relationships given the firm size and environmental characteristics, separate analyses in each group indicate that a proactive market orientation may be more important for small firms and firms operating amidst a higher level of technological turbulence. This study suggests that a distinction between a responsive and a proactive market orientation is important for a better understanding of the effect of a market orientation on the degree of novelty.responsive and proactive market orientation, incremental and radical innovation

Hierarchical visualization of large networks

We expose the principles of agglomerative clustering of networks and propose a new efficient link clustering algorithm with a relational constraint, bound implicitly to the corresponding line graph of the input network. Along we develop dissimilarity measures, which besides the network structure consider properties of network elements. We evaluate the algorithm on a set of networks, including bibliographic networks from the field of topological indices. Using existent and new scientometric network analysis approaches we analyze them in detail. We design a method for general hierarchy visualization and develop a visualization method for mobile networks. We use the methods on suitable networks. Considering the principles of abstraction and interactivity we develop a new extendable tool for continuous analysis and visualization of large networks – net.Plexor, which introduces new structured real-time approaches into the network analysis, advanced methods of visualization and upper methods. We conclude the work with an overview of network file formats, and give advice on network data collection and storage

Responsive and proactive market orientation and innovation success under market and technological turbulence

The study investigates how market and technological changes in an organization's business environment moderate the relationships between responsive and proactive market orientation, innovation success, and market success of the organization. The respondents in the study were senior managers of companies operating in a Central European country. The Internet survey resulted in 441 usable questionnaires. Data were analyzed using a non-linear structural equation models with MPLUS5. The results provide support for distinguishing between the two complementary forms of market orientation, proactive and responsive. While proactive market orientation is a determinant of both innovation and market success of the organization, the impact of responsive market orientation on the innovation and market success is positive and significant only in a rapidly changing market environment. Companies can improve their innovation success and in turn market success by improving their proactive market orientation, i.e. by investing resources in exploring customer needs, customer problems with existing products and latent customer needs. The study contributes to the literature by examining the entire chain of relationships between market orientation, innovation success and market success by adopting both a responsive and proactive market orientation. It is the first study that examines these relationships in the context of companies from a European country and with consideration of market turbulence/changes

Higher mortality of patients on haemodialysis with pancreatic diabetes compared to type 2-diabetes

In rare cases (1-8%) diabetic patients with end-stage renal disease (ESRD) suffer from diabetic nephropathy (dNP) due to pancreatic diabetes mellitus (PDM). Aim of this study was to investigate differences in the outcome of patients with PDM and those with type 2 diabetes

Diurnal Variation of Pulse Wave Velocity Assessed Non-Invasively by Applanation Tonometry in Young Healthy Men

We present a family of unconditionally stable algorithms, based on the Suzuki product-formula approach, that solve the time-dependent Maxwell equations in systems with spatially varying permittivity and permeability. Salient features of these algorithms are discussed. As an illustration we compute, as a function of cluster size, the spectrum of electromagnetic modes in a cluster of photonic bandgap material.
