BACKGROUND Advances in communication technology may affect networking pattern, thereby influencing the dynamics of sex partnership. The aim of the study is to explore the impacts of partner sourcing through internet and related channels on exposure risk to sexually transmitted infections (STI) including HIV. METHODS Using venue-based sampling, a cross-sectional questionnaire survey was conduc...

Taylor Guitars purchased an ebony mill in Cameroon to ensure corporate social and environmental responsibility (CSER) in sourcing, and shared the responsibly-sourced supply of ebony with competitors through horizontal sourcing. Inspired by this case, we investigate vertical integration as an alternative strategy for CSER in sourcing in which a firm can vertically integrate with its supplier in ...

Firms use information systems to reduce the costs of doing business and create innovative applications and products for competitive advantage. IT outsourcing, often to overseas locations, appears to have accomplished efficiency improvements. However, firms increasingly employ global sourcing of IT services for other purposes, such as to broaden the scope of provided services and for strategic c...

The trend for businesses to outsource information technology (IT) resources remains a relevant topic among IS researchers (Hirschheim and Lacity 2000, Kern & Blois 2002, Yost & Harmon 2002, Dibbern et al. 2004). While much has been written about outsourcing, the literature is relatively sparse when contemplating the issue of how organizations actually make their IT sourcing decisions. These sou...

Ubiquitous crowd-sourcing has become a popular mechanism to harvest knowledge from the masses. OpenStreetMap (OSM) is a successful example of ubiquitous crowd-sourcing, where citizens volunteer geographic information in order to build and maintain an accurate map of the changing world. Research has shown that OSM information is accurate, by comparing it with centrally maintained spatial informa...

Cities are highly dynamic entities, with urban elements such as businesses, cultural and social Points-ofInterests (POIs), housing, transportation and the like, continuously changing. In order to maintain accurate spatial information in these settings, crowd-sourcing models of data collection, such as in OpenStreetMap (OSM), have come under investigation. Like many crowd-sourcing platforms (e.g...

In this paper we propose a non-metric rankingbased representation of semantic similarity that allows natural aggregation of semantic information from multiple heterogeneous sources. We apply the ranking-based representation to zeroshot learning problems, and present deterministic and probabilistic zero-shot classifiers which can be built from pre-trained classifiers without retraining. We demon...

The concept of strategic sourcing recognizes that procurement is not just a cost function, but supports the firm’s effort to achieve its long-term objectives. Organizations more and more expect from their chief procurement officer (CPO) to develop long-term and short-term plans in procurement. Typically, however, procurement is driven by a tactical spend management sourcing process aimed at cos...
