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...

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 ...

The goal of this work is to introduce CHILDES-MWE, which contains English CHILDES corpora automatically annotated with Multiword Expressions (MWEs) information. The result is a resource with almost 350,000 sentences annotated with more than 70,000 distinct MWEs of various types from both longitudinal and latitudinal corpora. This resource can be used for large scale language acquisition studies...
