Abstract We investigated the reciprocal longitudinal relation between perceived stress and three established domains of views on aging (VoA): (1) subjective age; (2) attitude toward own [ATOA]; (3) aging-related cognitions including social loss, physical decline, continuous growth. also examined potentially moderating role chronological age. Data German Ageing Survey, comprising two measurement...

This paper investigates whether the business relations between mutual funds and brokerage firms influence sell-side analyst recommendations. Using a unique data set that discloses brokerage firms’ commission income derived from each mutual fund client as well as the share holdings of these mutual funds, we find that an analyst’s recommendation on a stock relative to consensus is significantly h...

This paper proposes causal models for representing relational information about the variables of a performance analysis. Causal structure learning algorithms are used for constructing such models from experimental data. However, the existing algorithms had to be extended to capture the complexity of performance models, since they contain a mixture of continuous and discrete variables, nonlinear...

 Modeling Mutual Influence Between Social Actions and Social Ties Xiaofeng Yu, Jun Qing Xie HP Laboratories HPL-2014-18 Social Actions and Social Ties; Mutual Influence In online social media, social action prediction and social tie discovery are two fundamental tasks for social network analysis. Traditionally, they were considered as separate tasks and solved independently. In this paper, we ...

The concept of intersectionality is reviewed and further developed for more effective use. Six dilemmas in the debates on the concept are disentangled, addressed and resolved: the distinction between structural and political intersectionality; the tension between ‘categories’ and ‘inequalities’; the significance of class; the balance between a fluidity and stability; the varyingly competitive, ...

We put forward in the present paper a general and very simple principle concerning order relations which unifies a number of diverse results in nonlinear functional analysis. These results include the normal solvability theorems, generalizations of the Bishop-Phelps theorem, invariance theorems for closed sets under flows in metric spaces, and a number of other new related results. It had been ...

We compare the elementary theories of Shannon information and Kolmogorov complexity, the extent to which they have a common purpose, and where they are fundamentally different. We discuss and relate the basic notions of both theories: Shannon entropy versus Kolmogorov complexity, the relation of both to universal coding, Shannon mutual information versus Kolmogorov (‘algorithmic’) mutual inform...

Ontologies are crucial in B2B electronic commerce in general and in the Virtual Enterprise scenario in particular, enabling the mutual understanding between multiple business participants. This paper considers the development of a specific ontology in the home automation business area, illustrated in the Virtual Enterprise formation process. The ontology developed for the home automation (domot...
