We study the problems of classification and closeness testing. A classifier associates a test sequence with the one of two training sequences that was generated by the same distribution. A closeness test determines whether two sequences were generated by the same or by different distributions. For both problems all natural algorithms are symmetric—they make the same decision under all symbol re...

Although both betweenness and closeness centrality are claimed to be important for the effectiveness of someone’s network position, it has not been explicitly studied which networks emerge if actors follow incentives for these two positional advantages. We propose such a model and observe that network dynamics differ considerably in a scenario with either betweenness or closeness incentives com...

EXECUTIVE SUMMARY Researchers have long argued that a ‘right’ degree of closeness among team members is necessary for innovation. At unhealthy extremes, while closeness leads to cloning and copycat attitude, increased distance can result in incompatibility and dissonance. Hence, actually building teams that possess ‘creative-tension’ is easier said than done. This paper develops specific factor...

Probabilistic graphical models allow us to encode a large probability distribution as composition of smaller ones. It is oftentimes the case that we are interested in incorporating model idea some these distributions likely be similar one another. In this paper provide an information geometric approach on how incorporate and see it allows reinterpret already existing models. Our proposal relies...

The relationship between a reeexive and its antecedent is characterized by (a) a locality condition, and (b) a syntactic prominence condition. In Chomsky (1981) locality is deened in terms of governing category, and syntactic prominence is via c-command. In this article I show that, to account for the long-distance binding properties of complex reeexive ta-zijì3s-slef' in Chinese, which cast do...

Closeness is a widely-used centrality measure in social network analysis. For a node it indicates the inverse average shortest-path distance to the other nodes of the network. While the identification of the k nodes with highest closeness received significant attention, many applications are actually interested in finding a group of nodes that is central as a whole. For this problem, only recen...

AIM Studies have provided insights into factors that may facilitate or inhibit parent-infant closeness in neonatal units, but none have specifically focused on the perspectives of senior neonatal staff. The aim of this study was to explore perceptions and experiences of consultant neonatologists and senior nurses in five European countries with regard to these issues. METHODS Six small group ...

This study aimed to explore the relationship of students’ happiness, stress, and emotional closeness to others to help move towards evidence-based practices for this population. Therefore, the primary purpose of this study was to examine whether college students’ perceived happiness differed significantly based on stress, frequency of stress management techniques, and emotional closeness to oth...

BACKGROUND Research shows evidence for the importance of physical and emotional closeness for the infant, the parent and the infant-parent dyad. Less is known about how, when and why parents experience emotional closeness to their infants in a neonatal unit (NU), which was the aim of this study. METHODS A qualitative study using a salutogenic approach to focus on positive health and wellbeing...
