Increased out-of-pocket (OOP) health care spending has been associated with increased maternal, infant, and child mortality, but the effect of public health care spending on mortality has not been studied. I identified a statistically significant interaction between public health care expenditure and OOP health care spending for maternal, infant, and child mortality. Generally, increases in public expenditure coincide with decreased rates of mortality, regardless of OOP spending levels. Specifically, higher levels of public expenditure with moderate levels of OOP spending may result in the lowest mortality rates. Increased public health care spending may improve health outcomes better than efforts to reduce OOP expenditure alone.

The component-based software development enables to construct applications from reusable components providing particular functionalities and simplifies application evolution. To ensure the correct functioning of a given component-based application and its preservation across evolution steps, it is necessary to test not only the functional properties of the individual components but also the correctness of their mutual interactions and cooperation. This is complicated by the fact that third-party components often come without source code and/or documentation of functional and interaction properties. In this paper, we describe an approach for performing rigorous semi-automated testing of software components with unavailable source code. Utilizing an automated analysis of the component interfaces, scenarios invoking methods with generated parameter values are created. When they are performed on a stable application version and their runtime effects (component interactions) are recorded, the resulting scenarios with recorded effects can be used for accurate regression testing of newly installed versions of selected components. Our experiences with a prototype implementation show that the approach has acceptable demands on manual work and computational resources.

Programs organization and advancement that endeavor to kill a portion of the pitfalls of traditional programming strategies by data organized in a hierarchy of classes with several powerful new concepts. This paper displays another strategy for examining and reengineering Constructor in class hierarchies. In objectoriented Software (OOS), the accentuation is on data instead of procedure. Class is a way that ties the data and procedure together. Constructor is a special member procedure (SMP) class and destructor restores the memory delivers back to the program. The advancement comprises of exercises, for example, analyze, design, code, test, implement and maintenance. This paper gives the information about measuring the estimations of object oriented programming (OOP) advancement and proposed a Metric Measurement Model to guarantee that measurements of value properties are imperative in object oriented programming improvement.

Iterating over a set of elements is a very common operation in any program. Some programming languages provide native constructs to iterate over elements and for object-oriented progamming languages there exists guidance in form of design patterns on how to implement generic iteration functionality. However, there is just very few guidance of this kind for procedural programming languages like C. This paper provides such guidance and presents three patterns on how to design generic iterator interfaces in C.

Clabjects, the central construct of multi-level modeling, overcome the strict separation of class and object in conceptual modeling. Ruby, a dynamic object-orientedprogramming language, similarly treats classes as objects and thus appears as a natural candidate for implementing clabject-based modeling constructs. In this paper we introduce DeepRuby, a Ruby implementation of the core constructs of Dual Deep Instantiation: clabject hierarchies and attributes with separate source potency and target potency. DeepRuby represents clabjects at two layers: the clabject layer and the clabject facet layer. At the clabject facet layer, a clabject with maximum source potency i-1 and maximum target potency j-1 is represented by a matrix of i × j clabject facets organized using Ruby’s superclass and eigenclass constructs. Clabject facets can easily be extended with behavior implemented in custom methods.

The widespread use of service-oriented and cloud computing is creating a need for a communication-based programming approach to distributed concurrent software systems. Protocols play a central role in the design and development of such systems but mainstream programming languages still give poor support to ensure protocol compatibility. Testing alone is insufficient to ensure it, so there is a pressing need for tools to assist the development of these kind of systems. While there are tools to verify statically objectoriented code equipped with assertions, these mainly help to prevent runtime errors. However, a program can be illbehaved and still execute without terminating abruptly. It is important to guarantee that the code implements correctly its communication protocol. Our contribution is a tool to analyse source code written in a subset of Java, equipped with assertions, and return it annotated with its respective behavioural types that can be used to verify statically that the code implements the intended protocol of the application. A running example illustrates each step of the tool. Copyright 2017 ACM.
