Towards the strategies of modern societies: systems and social processes

While several sociological theories have traditionally dealt with rational action by human actors, little attention has been devoted to the possibilities for rational steering of the entire subsystems of functionally differentiated modern societies in the context of their increasing complexity. Although rational intentional action is clearly limited at the macro-level by the complexity emphasized by Luhmann's social systems theory, strategies are required to approach the normative ideal of active society as defined by Etzioni. Understanding the strategic processes requires micro–macro and agency–structure connections. A possible solution to understanding strategy as a social process in this respect is found in the adaptation of the three-level – individuality, reality and totality – approach of Sztompka's theory of social becoming.     

Availability of a system subject to hidden failure inspected at constant intervals with non-negligible downtime due to inspection and downtime due to repair/replacement

For systems with hidden or unrevealed failures, a common practice is to inspect the system regularly, since failures can only be detected upon inspection. Recent works in the literature have studied the availability of a system under periodic inspection, assuming perfect repair/replacement with non-negligible downtime due to repair/replacement for a detected failure. In some situations, however, not only downtime due to repair/replacement but also downtime due to inspection is non-negligible regardless whether a failure was detected or not. In this paper, we consider the availability of a system subject to hidden failure inspected at constant interval with both non-negligible downtime due to inspection and non-negligible downtime due to repair/replacement.     

An INAR(1) model based on a mixed dependent and independent counting series

A mixed integer-valued autoregressive model of order one, based on the binomial and the generalized binomial thinning operator is introduced. Geometric marginal distribution is considered. Properties of the model are analysed, unknown parameters are estimated and some numerical results of the estimates are obtained. Finally, model is applied on two real data sets and compared to some relevant models.     

Effects of screen filter on visibility of alphanumeric presentation on CRT and LCD monitors

In this paper, a research that deals with the problem of determining of the visibility of the alphanumeric presentation on CRT and LCD screens is presented, in conditions when the screen filters are used, and when they are not used. A methodology that can be used for determination of the visibility of alphanumeric symbols on VDT screens is presented. It is determined the existence of differences in visibility of alphanumeric presentations when screen filters are used, compared to conditions when they are not used. This difference was statistically significant, while the visibility of the presented alphanumeric symbols on CRT and LCD screens that use screen filters is lower than when they are not used. For this reason, the use of protective screen filter is recommended in circumstances where a very high level of glare exists, when the visual fatigue is common appearance and when a user performs a task that does not depend on the detection of stimuli whose RGB values are low.     

Implementation guidelines for mass customization: current characteristics and suggestions for improvement

Interest in mass customization (MC) is increasing in both industry and academia. Academic research on MC implementation guidelines (IGs) has, however, lagged behind other research streams in the MC literature. The present article reviews the existing literature on MC-IGs and inductively derives a classification scheme for prior research findings to identify potential areas for further research. While the issue of what enables MC has been intensively researched, investigation of several questions is still required, such as which enablers should be implemented and in what sequence, depending on the specific context in which MC is pursued. Other areas for future study of MC-IGs include applicability context specifications, as-is analysis tools, hindrance factors and required resources. This article complements previous MC literature reviews by providing an overview of MC-IGs available in the literature, identifying the building blocks of MC-IGs and proposing a definition of MC-IGs that can be used as a basis for future research in MC implementation.
