Although many approaches for architecturebased reliability estimation exist, these approaches are typically limited to certain classes or exclusively concentrate on software reliability, neglecting the influence of hardware resources, component reliability, component replica and software deployment. In this paper, a reliability estimation model based on software architecture (SA) is presented. ...

Does experimental evidence of the common difference effect imply that intertemporal preferences are time inconsistent? Do these features of choice suggest inherent characteristics of preferences, or could they be traced to an underlying factor that shapes the environment? The effect of uncertain lifetime on intertemporal preferences is studied. A demographic model that allows for unobservable h...

In this paper the authors discuss the misunderstanding that arose over the years around the broadly defined term of the objectrelational mismatch. It occurs in many different aspects of programming. There are three concerns considered the most important: mismatching data models, mismatching binding times and mismatching object lifecycle. This paper focuses on the data model mismatch. The author...

customer activity has received more attention due to the increase of social network applications. moreover, customer activity could be an answer to the research debate about the significant relationship between retention rate and lifetime profitability of customers. several researchers believe that an increase in the retention rate of customers may enhance their customer lifetime value (clv), o...

in the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. this lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. in this paper, a “service-life factor” has been defined. applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

Today, conceptual models are intensively used in the information systems discipline. They can support the development and adaptation of software systems as well as the (re-)design of organizations. As conceptual models change during their lifetime, there is a need to manage different version of models. Thus in the past years, findings in software configuration management has been transferred to...

Background. Bipolar disorders are often not recognized. Several instruments were developed but none primarily focused on hypomania. The Hypomania Checklist (HCL) is aimed at the identification of bipolarity in outpatients. Using a German and Swedish sample we investigated if the factor structure in non-clinical samples is similar to the one reported for outpatient samples. Furthermore we tested...

This study is rooted in the research traditions of cultivation theory, construct accessibility, and availability heuristic. Based on a survey with 221 subjects, this study finds that familiarity with direct-to-consumer (DTC) print advertisements for antidepressant brands is associated with inflated perceptions of the prevalence and lifetime risk of depression. The study concludes that DTC adver...

We present transient and asymptotic reliability indices for a single-unit system that is subject to Markov-modulated shocks and wear. The transient results are derived from the (transform) solution of an integro-differential equation describing the joint distribution of the cumulative degradation process and the state of the modulating process. Additionally, we prove the asymptotic normality of...

BACKGROUND The American Indian Service Utilization, Psychiatric Epidemiology, Risk and Protective Factors Project (AI-SUPERPFP) estimated the mental health burden and associated help-seeking in select American Indian reservation communities. OBJECTIVE To determine the lifetime and 12-month prevalence of common DSM-IV disorders, their demographic correlates, and patterns of help-seeking in 2 c...
