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...

This paper aimed to establish the relationship between food safety knowledge, shopping attitude, and self-reported kitchen practices among Romanian consumers. The study used data collected in an online survey applied on 985 A attitude practice (KAP) model by structural equation modelling revealed significant correlations knowledge (r = 0.36; p < 0.001). Also, depicted effects (? 0.17, 0.001; ? ...

This paper studies the effects of the structural variables of the Iranian industries sector on the welfare cost using to the Structure-Conduct-Performance (SCP) theory. In other words, we investigate the role of structural components and their effects on the size of the welfare cost in Iran's industry sector. We have used the Leibenstein's model to calculate the deadweight loss and then the pan...

This study described the development of a safety climate instrument for employees at three mini-steel mill locations in the U.S. The instrument was validated by structural equation modeling using AMOS and measured safety climate at a specific “point in time” to assess the safety culture of the industry. The Hall Safety Climate Instrument was developed using a three-construct theoretical framewo...

We propose a new type-theoretic foundation of Scala and languages like it: the Dependent Object Types (DOT) calculus. DOT models Scala’s path-dependent types, abstract type members and its mixture of nominal and structural typing through the use of refinement types. The core formalism makes no attempt to model inheritance and mixin composition. DOT normalizes Scala’s type system by unifying the...

As part of a preliminary hazard analysis for a new phenol plant, the results of a hazard and operability study (HAZOP) conducted in the initial stages of the project design were re-evaluated due mechanical failure detected during the test operation. Out of the possible mechanical defects for the crude phenol column (CPC), the fact that the lowest risk grade was given to the column without consi...

Actor-network theory, which is considered as a development of socio-technical structuralism school, observes reservation and stability of networks containing personal and impersonal components such as individuals, organizations, communication software and hardware, and infrastructural standards by examination of socio-technical dimensions concurrently.The goal of this research is studying the i...

We integrated psychosocial safety climate (PSC) with the job demands and resources (JD-R; Bakker & Demerouti, 2007) framework to examine the impact of both job demands and job resources at work on employee depression, anger, and engagement. PSC refers to a climate for the protection of employee psychological health and safety. As PSC theoretically influences the working environment, we hypothes...

The objective of this paper is to assess the promise of a novel tool for structural safety decisionmaking in severe unforeseen hazards. A straightforward measure is put forth for measuring the intensity of unforeseen hazards: the number of connected members removed from a structure in a brittle fashion. The tool selected for assessing this severe demand is the reduction in the buckling load cap...
