Abnormal fear responding to threat cues may contribute to the aetiology and maintenance of persistent fears and pathological anxiety. Chronic anxiety may also involve abnormal fear responding to ‘safety’ cues, which do not signal danger. Yet investigations of fear responding to acquired safety cues are scarce and the basis of such responding remains unclear. Moreover, previous studies do not di...

We report on the issues raised when designing a customizable locking mechanism for Persistent Java, a type-safe, object-oriented, orthogonally persistent system based on the language Java. Customizable locking mechanisms are supported by locking capabilities. A locking capability is a book-keeper of locks that automatically acquires locks with a customizable connict detection mechanism. It impl...

OBJECTIVE To develop and validate a mechanism for patients to provide feedback on safety experiences following a care transfer between organisations. DESIGN Qualitative study using participatory methods (codesign workshops) and cognitive interviews. Workshop data were analysed concurrently with participants, and cognitive interviews were thematically analysed using a deductive approach based ...

OBJECTIVES The purpose of this nationwide intervention was to improve machine safety in small metal fabrication businesses (3 to 150 employees). The failure to implement machine safety programs related to guarding and lockout/tagout (LOTO) are frequent causes of Occupational Safety and Health Administration (OSHA) citations and may result in serious traumatic injury. METHODS Insurance safety ...

The standard JVM invokes a complex, resource-consuming, bytecode veriier to ensure the type-safety of untrusted code. Such protection mechanism is unpractical for VM's deployed on small devices or built for high-performance applications. This motivates the need for distributed veriication systems, in which a mobile code runtime environment shares some or all of its veriication burden with certa...

Background: Current study aimed to investigate whether perceived neighborhood as unsafe during adolescence predicts the subsequent perceived health two decades later. Methods: In a prospective study of an ethnically diverse urban sample (83.2% Black), conducted from 1994 to 2012, 851 adolescents were enrolled at 9th grade. Three hundred and seventy‐eight participants were followed from 9th grad...

Preliminary work on the development of measures appropriate for the safety domain is reported. Measures are expressed in the style of the Practical Software and Systems Measurement (PSM) approach, a programme sponsored by the US DoD. Proposed measures are integrated with the PSM measurement framework. Reported work has been informed by discussions within the PSM community and by concurrent work...

Vehicular ad hoc networks can play an important role in enhancing transportation efficiency and improving road safety. Therefore, direct vehicle-to-vehicle communications are considered as one of the main building blocks of a future Intelligent Transportation System. The success and availability of IEEE 802.11 radios made this technology the most probable choice for the medium access control la...
