Class cohesion metrics apply different approaches to quantify the relatedness of the attributes and methods in a class. These relations can be direct or transitive. Method invocations are among the key sources of potential transitive attribute-method relations. That is, a method is not only related to the attributes that it references, but it may also be transitively related to the attributes r...

Safety standards (e.g., ISO 26262) define safety life-cycles to be adopted for the development of safety-critical systems. Professionals (i.e., safety engineers, safety managers, and, more broadly safety cultureaware personnel) who are responsible of the development of such systems can be, in turn, considered as safety-critical systems. Coursemodules aimed at forming such professionals are crit...

System-level design methodologies have been introduced as a solution to handle the design complexity of mixed Hardware / Software systems. In this paper we describe a system-level design flow starting from Simulink specification, focusing on concurrent hardware and software design and verification at four different abstraction levels: System Simulink model, Transaction Simulink model, Macro arc...

ARIES-AT is a 1000 MWe conceptual fusion power plant design with a very low projected cost of electricity. The design contains many innovative features to improve both the physics and engineering performance of the system. From the safety and environmental perspective, there is greater depth to the overall analysis than in past ARIES studies. For ARIES-AT, the overall spectrum of off-normal eve...

Safety engineering standards define rigorous and controllable processes for system development. Nevertheless, safety standards differences from distinct domains are non-negligible. We focus in particular on the aviation, automotive and railway standards, all related to the transportation market. We argue that the Safety Integrity Levels are not sufficient to be used as a top level requirement f...

conclusions iraqi nurses identified factors such as limited health resources, lack of job description, and professional unaccountability as major safety issues in maternity services. these findings alarm the need to ensure the provision of females and neonates with appropriate care. this, however, would require coordination between iraqi kurdistan health authorities to provide midwifery care fa...

This article clarifies how leader behavioral integrity for safety helps solve follower's double bind between adhering to safety protocols and speaking up about mistakes against protocols. Path modeling of survey data in 54 nursing teams showed that head nurse behavioral integrity for safety positively relates to both team priority of safety and psychological safety. In turn, team priority of sa...

OBJECTIVES Current literature emphasises that clinical leaders are in a position to enable a culture of safety, and that the safety culture is a performance mediator with the potential to influence patient outcomes. This paper aims to investigate staff's perceptions of patient safety culture in a Danish psychiatric department before and after a leadership intervention. METHODS A repeated cros...
