In general, building and validating a certification path connecting a trust anchor to a target can be a very timeconsuming process. As such, any optimizations are valuable. Certification paths are commonly built from the target to the trust anchor (“building in the forward direction”) or from the trust anchor to the target (“building in the reverse direction”). This paper presents a comparison ...

Building commonsense knowledge bases is a challenging undertaking. While we have witnessed the successful collection of large amounts of commonsense knowledge by either automatic text mining or games with a purpose (GWAP), such data are of limited precision. Verifying data is typically done with repetition, which works better for very large data sets. Our research proposes a novel approach to d...

OBJECTIVES To describe tobacco industry involvement in the organisation and financial support of an air quality research laboratory in El Salvador. METHODS Tobacco industry documents on the internet were systematicall...

Seafood supply chains are complex, not least in the diverse origins of capture fisheries and through aquaculture production being increasingly shared across nations. The business-to-business (B2B) seafood trade is supported by shows that facilitate networking act as fora for signaling perceptions values. In Global North, sustainability related certifications messaging have emerged an important ...

Background In addition to clinical work, ultrasound training often takes place through the completion of certified courses. Quality assurance represents a challenge for implementation For this purpose, in certifications (e.g. DEGUM), previously non-standardized theoretical learning success controls are carried out. We have developed “direct observation procedural skills” (DOPS) especially head ...

Widely-used online ‘‘trust” authorities issue certifications without substantial verification of recipients’ actual trustworthiness. This lax approach gives rise to adverse selection: the sites that seek and obtain trust certifications are actually less trustworthy than others. Using an original dataset on web site safety, I demonstrate that sites certified by the best-known authority, TRUSTe, ...

A growing number of IT professionals believe that being certified will give them advantages when looking for jobs and many managers use IT certification as a selection tool when hiring. However, some managers have questioned the value of certifications or of some certifications in particular. The purpose of this research is to determine the factors that predict managers’ intentions to use IT ce...

Laser allows attackers to realize very efficient attacks which threaten the security of digital systems [FA06]. These attacks consist in using a laser to inject errors at specific times targeting specific components in the digital system. This digital system is a hardware architecture which executes a software application. The injected errors can then be propagated or masked, both by the hardwa...
