Purpose – The purpose of this paper is to describe the implementation of 3D printing and maker spaces in various library settings. Insights, challenges, successes, projects as well as recommendations will be shared. Commonalities across libraries 3D printing technologies and maker space learning areas will also explored. Design/methodology/approach – This paper delves into six case studies of l...

In this paper we consider biased Maker-Breaker games played on the edge set of a given graph G. We prove that for every δ > 0 and large enough n, there exists a constant k for which if δ(G) ≥ δn and χ(G) ≥ k, then Maker can build an odd cycle in the (1 : b) game for b = O ( n log n ) . We also consider the analogous game where Maker and Breaker claim vertices instead of edges. This is a special...

We present HTN-MAKER, an offline and incremental algorithm for learning the structural relations between tasks in a Hierarchical Task Network (HTN). HTN-MAKER receives as input a STRIPS domain model, a collection of STRIPS plans, and a collection of task definitions, and produces an HTN domain model. HTN-MAKER is capable of learning an HTN domain model that reflects the provided task definition...

Making is considered to be democratizing technology design and production. Yet, in many cases, in order to be a successful maker or have a rewarding maker experience, participants/makers need to bring in some form of expertise, creating both implicit and explicit barriers for differentiated publics to take part. We explore the literature and existing scholarship regarding expertise and making, ...

1 Who knoWs a utility representation Repeatedly it is alleged that this or that theory concerns a decision maker maximizing some utility function. But, as I have been at pains to discuss, the representation is not a creature of the decision maker but of the scientist studying the decision maker’s behavior “The representation theorems go in only one direction: from behavioral and structural prop...

The Maker Movement, while heralded for popularizing DIY culture, has recently drawn some critiques for the ways in which the mass-marketing of maker culture partially obscures the social, cultural, and political implications of making. A number of educators, designers, and researchers are actively studying alternative approaches to maker culture, and specifically developing ways to broaden part...

We look at Maker-Breaker k-clique game played on the edge set of the random graph G(n, p). In this game, two players, Maker and Breaker, alternately claim unclaimed edges of G(n, p), until all the edges are claimed. Maker wins if he claims all the edges of a k-clique; Breaker wins otherwise. We determine that the property that Maker can win this game has a threshold at n− 2 k+1 , for all k > 3....

In a biased weak (a, b) polyform achievement game, the maker and the breaker alternately mark a, b previously unmarked cells on an infinite board, respectively. The maker’s goal is to mark a set of cells congruent to a polyform. The breaker tries to prevent the maker from achieving this goal. A winning maker strategy for the (a, b) game can be built from winning strategies for games involving f...
