HS-stability and complex products in involution semigroups

When does the complex product of a given number of subsets of a group generate the same subgroup as their union? We answer this question in a more general form by introducing HS-stability and characterising the HS-stable involution subsemigroup generated by a subset of a given involution semigroup. We study HS-stability for the special cases...

Counting Finite-Dimensional Algebras Over Finite Field

In this paper, we describe an elementary method for counting the number of non-isomorphic algebras of a fixed, finite dimension over a given finite field. We show how this method works in the case of 2-dimensional algebras over the field F₂.

Differential patterns of age-related cortical and subcortical functional connectivity in 6-to-10 year old children: A connectome-wide association study

Introduction: Typical brain development is characterized by specific patterns of maturation of functional networks. Cortico-cortical connectivity generally increases, whereas subcortico-cortical connections often decrease. Little is known about connectivity changes amongst different subcortical regions in typical development. Methods: This...

A research roadmap to advance data collaboratives practice as a novel research direction

An increasing number of initiatives have emerged around the world to help facilitate data sharing and collaborations to leverage different sources of data to address societal problems. They are called “data collaboratives”. Data collaboratives are seen as a novel way to match real life problems with relevant expertise and data from across...

Data Collaboratives as a New Frontier of Cross-Sector Partnerships in the Age of Open Data: Taxonomy Development

Data collaboratives present a new form of cross-sector and public-private partnership to leverage (often corporate) data for addressing a societal challenge. They can be seen as the latest attempt to make data accessible to solve public problems. Although an increasing number of initiatives can be found, there is hardly any analysis of these...

Data collaboratives as “bazaars”?: A review of coordination problems and mechanisms to match demand for data with supply

Purpose: In “data collaboratives”, private and public organizations coordinate their activities to leverage data to address a societal challenge. This paper aims to focus on analyzing challenges and coordination mechanisms of data collaboratives. Design/methodology/approach: This study uses coordination theory to identify and discuss the...

Data Collaboratives: How to create value from data for public problem solving? Panel

This panel is dedicated to the theme of 'data collaboratives', a novel form of public private partnership to leverage data for addressing societal challenges. The panel brings together prolific researchers and practitioners to share lessons and discuss how value is created from data collaboratives for the solving of public problems. The panel...

The role of human factors in the adoption of sustainable design criteria in business

Implementing sustainability in business is steadily gaining more attention. A growing number of companies currently work on the implementation of sustainable criteria in the design related departments and their design processes. Although theory and methods are available, practice shows that this integration process of sustainability criteria is...

Schakeling: Moodlight: Op basis van een RGB-led

Op dit moment liggen de winkels vol met zogenaamde moodlights in verschillende soorten en maten. Vooral de kleurveranderende lampen zijn de laatste tijd erg in trek. Wie zijn wij dan als Klushokcommissie om daar dan niet op in te springen en daar een mooie Do It Yourself-versie van te maken. De schakeling is eigenlijk de basis van een veel...
