A variety of ’best practice’ guides to multiple choice question writing exist in the literature, each commonly containing a set of specific recommendations. One such recommendation entails the use of ’none of the above’ (NOTA), with some authors discouraging and others advocating its use on multiple choice tests. Empirical research on the use of NOTA has produced mixed results regarding its eff...

Flexible mass customization of buildings is still in its infancy. Current systems for the automated support of ownerdriven configuration management are limited with regard to the degree of freedom they offer to end-users, due to the lack of an easy way to specify those freedoms. In this paper we present the prototype of an interface that allows architects to define constraints to which user-cus...

HELEN DAWSON,

This paper explores the relations between island settlement, identity and sense of place in the prehistoric Mediterranean. It uses modern examples and archaeological case studies to discuss the effects of colonisation and abandonment on island communities and the creation of distinctive identities as a form of cultural resistance. Abandonment had a homogenising effect on prehistoric cultures, a...

Many problems of cooperation involve repeated interactions among the same groups of individuals. When collective action is at stake, groups often engage in Public Goods Games (PGG), where individuals contribute (or not) to a common pool, subsequently sharing the resources. Such scenarios of repeated group interactions materialize situations in which direct reciprocation to groups may be at work...

Kenneth R. Olson,

I remember as a neophyte academician in the early 80’s the excitement and at times heated discussion generated by nitric oxide (NO). How could this toxic and relatively unheard-of gas possibly be a regulatory molecule? Even its discovery was the result of a laboratory mistake (Furchgott, 1995). As with any revolutionary idea, there were both zealous aficionados, naysayers and folks in between t...

Transient associations among neurons are thought to underlie memory and behavior. However, little is known about how such associations occur or how they can be identified. Here we recorded ongoing local field potential (LFP) activity at multiple sites within the cortex of awake monkeys and organotypic cultures of cortex. We show that when the composite activity of a local neuronal group exceeds...

Research on the integrated NC conceptual layout design (I-NCC) concerned with a broader area of interests. The key issues of I-NCC system are associated with NURBS and agent. Firstly, formulas for the derivatives and normal vectors of non-rational B-spline and NURBS are proved based on de BOOR’s recursive formula. Compared with the existing approaches targeting at the non-rational B-spline basi...

Uniquely in the industrialized world, the United States has long had the presumption that employers may legally fire workers “at will,” that is, “for good cause, bad cause, or no cause at all.” During the 1970’s and 1980’s, this presumption eroded rapidly: most U.S. state courts created three classes of common-law restrictions that limited employers’ ability to fire. These exceptions garnered m...
