Reuse of software has been one of the main goals of software engineering for decades. With the emergence of the object-oriented paradigm, an important enabling technology for reuse of larger components became available and resulted in the definition of object-oriented frameworks. Our and others experiences with frameworks have shown that frameworks indeed provide considerable reuse in framework...

BACKGROUND The prevention of overweight sometimes raises complex ethical questions. Ethical public health frameworks may be helpful in evaluating programs or policy for overweight prevention. We give an overview of the purpose, form and contents of such public health frameworks and investigate to which extent they are useful for evaluating programs to prevent overweight and/or obesity. METHOD...

The fractional weak discrepancy of a poset P , written wdF (P ), is the least k such that some f : P → R satisfies f(y)− f(x) ≥ 1 for x ≺ y and |f(y)− f(x)| ≤ k for x‖y. We determine the minimal forbidden subposets for the property wdF (P ) ≤ k when k is an integer.

Managing project success is an ongoing concern in both research and practice. The existing literature suggests theoretical frameworks for defining project success; however there is a lack of studies exploring how to apply these frameworks into a particular organisation. Additionally, there is a lack of practical processes for managing project success. Furthermore, the extant literature does not...

addiction to drugs, such as heroin, cocaine and alcohol, exacts great human and financial costs on society. various evidence-based pharmacological and psychosocial interventions are currently used in the treatment of drug addiction but they do not produce adequate therapeutic benefits in every patient. further, barriers such as financial cost, lack of availability, or perceptions of existing tr...

This paper argues that although there is no lack of eGovernment “frameworks”, both governments and research are both in need of better guiding models in order to address contemporary and future challenges. This argument is pursued by reviewing a decade of eGovernment development and research in terms of the guiding values as expressed by influential maturity models and relating them to the eGov...

A closed set of exact equations describing statistical theory of turbulent self-diffusion by multivariate-normal turbulent velocity field is derived. In doing so, we first suggest exact formulas for correlations 〈fi(p)fj(p ′)R[f ]〉, 〈g(p)R[f ]〉 and 〈g(p)fj(p ′)R[f ]〉 when the functional R[f ] is functional of functions fi’s having multivariate-normal distribution, g and fi’s have joint normal d...

abstract aim and background: the key purpose of the study was to investigation the relationship of job burnout and some of job variables like type and level of responsibility, service and mangement experiences. method and materials: this descriptive study was conducted on 245 managers and vice-chancellors randomly selected by the cluster-sampling technique. they were assessed by job burnout que...
