Within the context of flux tube models, heavy quark fragmentation takes place through the breaking of flux tubes with the production of a (di)quarkanti(di)quark pair. It is found that the (di)quark produced are more likely to be found in an Lz = 0 state. This naturally leads to an supression of the polarization distribution parameters w3/2 and w̃1 for (D1,D ∗ 2) and (Λc1,Λ ∗ c1) production respe...

The characteristics of current society and the interest about citizenship education in the context of lifelong learning are essential for a study that aims to describe and understand the development of social and civic competence in the educational field. A Delphi study can make a proposal in which the social and civic competence is composed of 89 items organised into five areas: knowledge, ski...

The Internet changed from a pure information media to a distribution channel, challenging companies in measuring the performance of their online distribution channels. Multi-channel retailers are particularly concerned since they need to coordinate their efforts with traditional, offline retailing activities. The paper at hand presents a corresponding metrics system derived from literature and ...

During 1996 and 1997 two empirical investigations into the importance of management of technology (MOT) issues (unresolved MOT problems) were completed. In these studies more than 150 academic and industry participants @om 17 countries evaluated the importance of each MOT issue relative to the others of its study. Each stu~ used a DELPHIIssues Questionnaire methodology which involved multiple q...

Big data and its applications have increasingly received interest by both scholars and practitioners. However, there is still missing evidence regarding how big data is understood as well as its applications in supply chain management (SCM). Empirical contributions are especially limited. This study seeks to address this gap through an explorative Delphi study to understand the terminology of b...

ALEPH and DELPHI were the first experiments operating a silicon vertex detector at LEP. During the past 10 years of data taking the DELPHI Silicon Tracker was upgraded three times to follow the different tracking requirements for LEP 1 and LEP 2 as well as to improve the tracking performance. Several steps in the development of the pattern recognition software were done in order to understand a...

Universes with multiconnected spatial sections predict multiple images of cosmic sources. A confusing terminology exists in the naming of these images as real ones vs. ghosts. Here an attempt is made to clarify the situation.

Greece is a country where cancer screening is extremely problematic, according to data coming from the recent Delphi consensus study (Skroumpelos et al., 2013) as well as the studies issued by the Panhellenic Association for Continual Medical Research (PACMER) (Kamposioras et al., 2007; Mauri et al., 2009). Specifically concerning mammogram, the PACMER investigators reported a screening rate eq...

Health care professionals responsible for patients with complex wounds need a particular level of expertise and education to ensure optimum wound care. However, uniform education for those working as wound care nurses is lacking. We aimed to reach consensus among experts from six European countries as to the competencies for specialised wound care nurses that meet international professional exp...
