Creativity is the tendency to generate or recognize ideas, alternatives, or possibilities. Following a study on the genetic contribution to working in a creative profession, based on polygenic score analysis, we report the total heritability of this trait in a large sample of adult twins and their siblings registered with the Netherlands Twin Register. Data from 6755 twins and 1817 siblings wer...

This paper presents mwetoolkit+sem: an extension of the mwetoolkit that estimates semantic compositionality scores for multiword expressions (MWEs) based on word embeddings. First, we describe our implementation of vector-space operations working on distributional vectors. The compositionality score is based on the cosine distance between the MWE vector and the composition of the vectors of its...

This paper presents a critique of the normative, buyer-supplier literature and in addition suggests that the more empirically-based literature needs to expand its scope of attention beyond its traditional confines of attention. Four main deficiencies are identified within much of the existing buyer-supplier literature. Firstly, collaborative buyer-supplier theories fail to discriminate sufficie...

In social collaborative crowdsourcing platforms, the votes which people give on the content generated by others is a very important component of the system which seeks to find the best content through collaborative action. In a crowdsourced innovation platform, people vote on innovations/ideas generated by others which enables the system to synthesize the view of the crowd about an idea. Howeve...

The restructuring of the Chinese electricity sector in 2002 reshaped the market structure by vertically unbundling the dominant integrated firm and started the process of wholesale price liberalization. We estimate factor demands to study whether these reforms boosted productivity in the generation segment of the industry. Controlling explicitly for price-heterogeneity across firms and unobserv...

In this paper, we present a new Web cache sharing scheme. Our scheme reduces the duplicated copies of the same objects in global shared Web caches, even though the hot working set of each local cache can be duplicated. Experimental results show that the proposed scheme outperforms existing sharing schemes for the data set we considered.

A novel method using luminescent molecule sensors is described for in situ measurement of fluid film thickness along the tool rake face in machining. The method uses an optically transparent sapphire tool to access the rake face, and measurement of radiation emitted by luminescing molecules dispersed in a machining fluid. By measuring the intensity of the emission, the film thickness is estimat...

Anxiety is a feeling of worry and excessive concern against obscure danger about inner or outer threat, which occur in form of ambiguous fear. It finally causes physical problem and impairs social and occupational functions. Anxiety is the most common mental disorder. Nursing totally is a difficult job and because of their working environmental and activity, they always encountering with damage...

This paper presents e-Training DS, an instructor-oriented toolkit for the integration of portable game consoles in modern e-learning environments (e.g. MoodleTM). The tool is based on a general model in which the instructor maintains a library of mini-games that are easily produced by customizing generic game patterns (e.g. a simple jigsaw puzzle). The authors can then compile a working set of ...
