The paper deals with some aspects of metasystem transitions in the context of supercompilation. We consider the manifestations of the law of branching growth of the penultimate level in the case of higher-level supercompilation and argue that this law provides some useful hints regarding the ways of constructing metasystems by combining supercompilers. In particular we show the usefulness of mu...

Meta-analyses synthesize multiple primary studies and identify patterns of relationships. Differences in primary study methodological quality must be addressed for meta-analysis to produce meaningful results. No single standard exists for addressing these quality variations. Quality measurement scales are fraught with development and application problems. Several strategies have been proposed t...

We present the uniform meta-architecture of the TIGUKAT object model and show how it provides reflection in object management systems. Reflection is the ability for a system to manage information about itself and to access (or reason about) this information through the regular access primitives of the model. The TIGUKAT object model is purely behavioral in nature, supports full encapsulation of...

This paper focusses on how conflicts that arise during a design process and the management of conflicts can be modelled. A number of possible conflict types are distinguished and it is described how each of them can be detected during the design process, using an explicit meta-representation. Furthermore, it is shown how these conflict types can be analyzed and managed by means of strategic met...

Recent years have seen a growing reliance on "evidence-based" guidelines or consensus statements, in which rigorous, explicit methods are used to translate the complex findings of scientific research into operational recommendations for medical care. Various factors can affect the validity of the conclusions they express, however. The purpose of this review was to compare the levels of evidence...

Background and aims: Infertility is one of the most important conditions in reproductive system and there is no reliable estimates for global prevalence of infertility. Therefore, knowing the prevalence of infertility is important and can be effective in decision making. Methods: We systematically reviewed all published papers in Medline database and Scopus (1988–2010). Univariate and multivar...

conclusions there is a high prevalence of mets in the iranian adult population, with large variations based on different measurement criteria. therefore, prevention and control of mets should be considered a priority. objectives this study systematically reviewed the findings of all available studies on mets in the adult iranian population and estimated the overall prevalence of mets in this po...
