We construct tree-decompositions of graphs that distinguish all their k-blocks and tangles of order k, for any fixed integer k. We describe a family of algorithms to construct such decompositions, seeking to maximize their diversity subject to the requirement that they commute with graph isomorphisms. In particular, all the decompositions constructed are invariant under the automorphisms of the...

Humans and non-human animals often choose among different alternatives by seeking variety. Here we assessed whether variety-seeking, i.e. the tendency to look for diversity in services and goods, occurs in capuchin monkeys--South-American primates which--as humans--are omnivorous and susceptible to food monotony. Capuchins chose between a Variety-token, that allowed to select one among 10 diffe...

Although the corresponding literature contains a substantial number of studies on the relationship between psychological factors and attitude towards seeking professional psychological help, the role of some determinants remains unexplored, especially among Polish young adults. The present study investigated diversity among a large cohort of Polish university students related to attitudes towar...

In this paper we argue for a combined approach of logging analysis and interview techniques to evaluate the usability of web distributed applications. Logging analysis has proven as an efficient and effective method to investigate websites usability. However it seems insufficient for more complex applications. We outline a case study of a library search system, in which users’ information seeki...

This paper presents a task-based user study carried out to investigate how explicit roles assigned to group members affected collaborative information seeking behaviour during a travel planning task. 24 pairs participated our study where half of them were given a specific instruction to divide the roles into a searcher and writer, while others were given no such instruction. The evaluation look...

One opportunity to realize the diversity goals of academic health centers comes at the time of hiring new faculty. To improve the effectiveness of search committees in increasing the gender diversity of faculty hires, the authors created and implemented a training workshop for faculty search committees designed to improve the hiring process and increase the diversity of faculty hires at the Uni...

The role of the library has always been to provide the best possible service to all its patrons, possibly, at all time. ICT came up with the facility to enhance the library services. Wi-Fi raised the profile of the library service and met demand for new technologies and services. Using Wi-Fi, library can expand its services and can provide new technologybased services to its users. To analyze t...

This paper reviews the literature on the impact of ethnic diversity on economic development. Ethnically polarized societies are less likely to agree on the provision of public goods and more likely to engage in rent seeking activities providing lower levels of social capital. Initial conditions are important determinants of adverse development outcomes. The role of decentralization, democracy a...
