The influence of the mean stress on fatigue life of 10HNAP steel under random loading
2001
Abstract This paper contains the results of uniaxial random load fatigue tests with different mean values performed on 10HNAP steel specimens. The experimental fatigue life was compared with the life determined according to different methods of amplitude transformation of the cycles. Cycles were counted with the rain flow algorithm and damage was cumulated with the Palmgren–Miner hypothesis. It has been shown that in the case of “symmetric” stress histories with zero expected values, the mean values of selected cycles do not strongly influence the calculated fatigue life and transformation of the cycle amplitudes; hence, no mean stress correction for cycle mean values different from zero is…
Incidence of Stakeholders in the corporate social responsibility of micro, small and medium-sized enterprises of Santa Marta
2018
Abstract This article analyses the perception and application of corporate social responsibility (CSR) practices in a sample of 499 micro, small and medium enterprises (MSMEs) in the city of Santa Marta (Colombia) following the theory of Stakeholders. Specifically, the interdependence technique of exploratory factor analysis was used to determine the most influential Stakeholders in the execution of CSR practices. It was found that Stakeholders related to the value chain, the environment and corporate management favour social responsibility actions in local MSMEs. In contrast, community and government have less influence on the development of social responsibility practices in MSMEs. Additi…
Proposing an Entrepreneurial Process for the Co-creation of IT Value
2014
Published version of a chapter from the book M. Janssen, H. Scholl, M. Wimmer & F. Bannister (Eds.), Electronic Government : Springer Berlin Heidelberg, 2014. Also available on SpringerLink: http://dx.doi.org/10.1007/978-3-662-44426-9_26 Co-creation of IT value has received substantial focus from the IS research community over the past years. However, few if any have studied this phenomenon from a process perspective, and our understanding of the processes leading to successful co-creation is therefore limited. To address this shortcoming, we studied a complex, e-government case involving 38 government agencies intending to co-create value from a common IT platform. We used a mixed method a…
Government Architecture: Concepts, Use and Impact
2013
Part 3: Service Design and Improvement; International audience; Government architecture (GA) is a relatively young discipline in which concepts are slowly emerging. Often terms and concepts are used in various ways and there is no uniform agreement on these concepts. Further, the relationship between GA, benefits and public value creation is unclear. In this paper we unravel and define GA concepts that are often used by governments. Although GA is used in different ways there are common concepts. GA practice in two different countries, the Netherlands and Norway, indicates that although the Netherlands clearly has more experience with GA than Norway, both countries employ similar concepts. …
Assessing Effects of eGovernment Initiatives Based on a Public Value Framework
2012
Published version of a chapter in the book: Electronic Government. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-33489-4_21 Assessing effects of eGovernment initiatives is considered an important but challenging endeavor. Assessments are, among other things, important to justify e-government investments. They are challenging because they are complex, often based on locally defined indicators, many times over-emphasizing financial effects, imprecise, faced with a number of contingencies and very seldom validated. Consequently, effect assessments can be seen as imprecise and difficult to compare across different initiatives. This paper addresses some of the challen…
Towards a Theoretical Model for Co-Realization of IT Value in Government
2015
Despite decades of heavy investments in information technology (IT) and information systems (IS) in government systems and considerable amounts of research on how IS contributes to organizational performance and success, IS investments are still considered risky business. Fewer than 50% of IS projects deliver the expected functionality on time and on budget. As the world becomes increasingly more complex, IS increasingly needs to function across organizational boundaries. The added complexity is likely to add to the risks of IS investments. Hence, there is a need to improve practice and to increase the success rate of IS investments, especially in government settings. To address this fundam…
Religion and Social Integration in France
2013
On some measures, France has the most integrated (and secularised) Muslim population in Europe. For example, attitude research shows that French Muslims share values closer to those of their non-Muslim neighbours than in other European countries (Connor 2010 391). While official sources of data are limited as the French government does not collect statistics organised by religion, ethnicity or any other form of collective identity, a number of private and international surveys have been carried out. Thus, the European Values Survey (2002–6 data) shows that rates of religious observance for Muslims in France are closer to those amongst the majority population than in either Britain or the Ne…
Spectral analysis of the Neumann-Poincaré operator and characterization of the stress concentration in anti-plane elasticity
2012
When holes or hard elastic inclusions are closely located, stress which is the gradient of the solution to the anti-plane elasticity equation can be arbitrarily large as the distance between two inclusions tends to zero. It is important to precisely characterize the blow-up of the gradient of such an equation. In this paper we show that the blow-up of the gradient can be characterized by a singular function defined by the single layer potential of an eigenfunction corresponding to the eigenvalue 1/2 of a Neumann–Poincare type operator defined on the boundaries of the inclusions. By comparing the singular function with the one corresponding to two disks osculating to the inclusions, we quant…
A sub-supersolution approach for Neumann boundary value problems with gradient dependence
2020
Abstract Existence and location of solutions to a Neumann problem driven by an nonhomogeneous differential operator and with gradient dependence are established developing a non-variational approach based on an adequate method of sub-supersolution. The abstract theorem is applied to prove the existence of finitely many positive solutions or even infinitely many positive solutions for a class of Neumann problems.
Unified thermodynamic framework for nonlocal/gradient continuum theories
2003
Abstract A thermodynamic framework, equipped with the concept of nonlocality (energy) residual, is utilized to address nonlocal/gradient internal variable material models. A unified procedure is provided for either nonlocal and gradient materials, which makes it possible to determine the thermodynamic restrictions upon the constitutive equations, and in particular the pertinent state equations, the consistent form of the dissipation power and the constitutive expression of the nonlocality residual. Additionally, for gradient models, the associated nonstandard boundary conditions are derived, pointing out their basically constitutive nature and their substantial differences from the standard…
