Bridging the gap between design and implementation of components libraries

Object-oriented design is usually driven by three main reusability principles: step-by-step design, design for reuse and design with reuse. However, these principles are just partially applied to the subsequent object-oriented implementation, often due to efficienc y constraints, yielding to a gap between design and implementation. In this paper we provide a solution for bridging this gap for a concrete framework, the one of designing and implementing container-like component libraries, such as STL, Booc h Components, etc. Our approach is based on a new design pattern together with its corresponding implementation. The proposal enhances the same principles that drive the design process: step-by--step implementation (adding just what is needed in every step), implementation with reuse (component implementations are reused while library implementation progresses and component hierarchies grow) and implementation for reuse (intermediate component implementations can be reused in many different points o f the hierarchy). We use our approach in two different manners: for building a brand-new container-like component library, and for reengineering an existing one, Booch Components in Ada95.Postprint (published version

What You Need to Know about Bar-Code Medication Administration

Medication errors are the most common type of preventable error. Bar-code medication administration (BCMA) technology was designed to reduce medication administration errors. Poor system design, implementation and workarounds remain a cause of errors. This paper reviews the literature on BCMA, identifies a gap in the findings and identifies three evidence based practices that could be used to improve system implementation and reduce error. The literature review identified that Bar-code medication administration and system workarounds are well documented and affect patient safety. Based on the critical analysis of 10 studies, we identified gaps in the standardization of BCMA planning, implementation, and sustainability. The themes that emerged from the literature were poor BCMA design and implementation that resulted in workarounds.The three evidence based strategies proposed to address this gap are, evidence based standardization in planning and implementation, the identification and elimination of workarounds and hard wiring. An evidence based checklist evaluates compliance with standard procedures. The LEAN model of Jodoka is used to assure adaptation of the machine to human workflow. Direct observation provides valuable workflow assessment. An effective BCMA implementation involves careful system design, identification of workflow issues which cause workarounds, and adapting the machine to nursing needs

Applying Gender Action Plan Lessons: A Three-Year Road Map for Gender Mainstreaming (2011- 2013)

This transition plan identifies key lessons from the implementation of the World Bank Group action plan, Gender Equality as Smart Economics (GAP), and sets out a proposal to improve the performance on Gender and Development. It seeks to strengthen the implementation of the Bank?s gender policy and places special emphasis on improving attention to gender in Bank instruments (CASs). It covers World Bank Group (WBG) operations from 2011 to 2013, and was produced on a request by the World Bank Board of Executive Directors. A GAP Three-year Progress Report accompanies this plan

Outlines a strategy for bridging the gap between low-income neighborhoods and regional workforce development programs. Describes nine implementation steps of a model for increasing career opportunities, and evaluates the feasibility of the program

Conditioning U.S. Security Assistance on Human Rights Practices

In the United States, with its government of separated powers and functions, it is the executive branch, and in particular the Department of State, that bears responsibility for implementing legislation on foreign relations. The success of implementation will depend on political decisions, involving competing national interests, as well as on institutional and personal considerations of I he officials concerned. Inevitably, there is a gap between legislation and execution, especially when the Executive is not wholly sympathetic to the law. The gap may even devour legislated policies as the Executive refuses to take Care that the Laws be faithfully executed, and bureaucratic and personal considerations distort judgments, exploit the generality and uncertainty of language, and lead to abuse of discretion. A notable instance of this problem has been executive implementation of legislation on international human rights
