A Framework for Program DevelopmentBased on Schematic

چکیده
Often, calculi for manipulating and reasoning about programs can be recast as calculi for synthesizing programs. The diier-ence involves often only a slight shift of perspective: admitting metavari-ables into proofs. We propose that such calculi should be implemented in logical frameworks that support this kind of proof construction and that such an implementation can unify program veriication and synthesis. Our proposal is illustrated with a worked example developed in Paulson's Isabelle system. We also give examples of existent calculi that are closely related to the methodology we are proposing and others that can be prootably recast using our approach.

Evaluating Health in All Policies; Comment on “Developing a Framework for a Program Theory-Based Approach to Evaluating Policy Processes and Outcomes: Health in All Policies in South Australia”
Health in All Policies (HiAP) has gained attention as a potential tool to address complex health and societal challenges at global, regional, national and subnational levels. In a recent article, Lawless et al propose an evaluation framework developed in the context of the South Australia HiAP initiative. Strategies, mediators, activities and impacts identified in the framework could potentiall...
متن کاملA rule-based system for automatic decidability and combinability
This paper deals with decision procedures specified by using a superposition calculus which is an inference system at the core of all equational theorem provers. This calculus is refutation complete: it provides a semi-decision procedure that halts on unsatisfiable inputs but may diverge on satisfiable ones. Fortunately, it may also terminate for some theories of interest in verification, and t...
متن کاملA Compilation Framework for Languages with Dynamic Thread Creation
The e ciency of multithreading is quite essential to the overall performance of concurrent object-oriented languages. It is very ine cient to implement such languages by using thread libraries. In this paper, we propose a framework that e ciently compiles languages which supports dynamic thread creation. In the framework, we designed and implemented a programming language Schematic, which is a ...
متن کاملPolicy, Theory, and Evaluation: Stop Mixing the Fruit Salad; Comment on “Developing a Framework for a Program Theory-Based Approach to Evaluating Policy Processes and Outcomes: Health in All Policies in South Australia”
The study of Health in All Policies (HiAP) is gaining momentum. Authors are increasingly turning to wide swathes of political and social theory to frame (Program) Theory Based (or Informed) Evaluation (TBE) approaches. TBE for HiAP is not only prudent, it adds a level of elegance and insight to the research toolbox. However, it is still necessary to organize theoretical thinking appropriately. ...
متن کاملHow Do We Evaluate Health in All Policies?; Comment on “Developing a Framework for a Program Theory-Based Approach to Evaluating Policy Processes and Outcomes: Health in All Policies in South Australia”
It is well-established that population health is influenced by a multitude of factors, many of which lie outside the scope of the health sector. In the public health literature it is often assumed that intersectoral engagement with nonhealth sectors will be instrumental in addressing these social determinants of health. Due to the expected desirable outcomes in population health, several countr...
