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...

BACKGROUND Disease is closely linked to the social context in which we live. Difficulty with communication, cultural incompatibility between patients and health care providers and socioeconomic obstacles are important barriers to quality care when doctors and patients come from different backgrounds and speak different languages. Red Cross War Memorial Children's Hospital (RCH) is a paediatric ...

Many diverse and important barriers, both real and perceived, inhibit automakers’ adoption of advanced composite materials. A strategy to produce an all-advanced-composite body-in-white (BIW) commercially could be the best method to overcome these barriers. This paper summarizes the ultralight, hybrid-electric “hypercar” concept, emphasizing why massoptimization is crucial to its design; summar...

Despite their potential to reshape business radically, information systems (IS) and information technology (IT) can be key inhibitors of industry transformation. In the automotive industry, although IT is a key enabler of process transformation, the existing IT systems constitute a significant barrier to change. While there are a number of models of change barriers, few have been validated in p...

This mixed methods study examined motivations and barriers to substance abuse treatment entry and treatment continuation among Asian American and Pacific Islander (AAPI) substance users. AAPI substance users (N = 61) were recruited from substance abuse treatment programs in California and Hawaii. Semi-structured interviews and interviewer-administered surveys assessed barriers and facilitators ...

Design and development of large blades is very challenging due to economics, logistics, and technical barriers. Regarding the technical barriers, designs must satisfy deflection, buckling, fatigue, and stability requirements. This is a very challenging design problem, and one that becomes more challenging to do costeffectively as blades grow even longer. Sandia National Laboratories has been re...

The ability of welfare-to-work clients to leave the welfare rolls and stay in the labor force is often limited by the work barriers they face. Using a sample of 1,404 female welfare-to-work clients we first examined the structure of work barriers and then tested their contribution to current work status in the context of a structural equation model that incorporated other central pathways to em...

We report multi-component high-entropy materials as extraordinarily robust diffusion barriers and clarify the highly suppressed interdiffusion kinetics in the multi-component materials from structural and thermodynamic perspectives. The failures of six alloy barriers with different numbers of elements, from unitary Ti to senary TiTaCrZrAlRu, against the interdiffusion of Cu and Si were characte...
