Implementation evaluations, also called process evaluations, involve studying the development of programmes, and identifying and understanding their strengths and weaknesses. Undertaking an implementation evaluation offers insights into evaluation objectives, but does not help the researcher develop a research strategy. During the implementation analysis of the UNAIDS drug access initiative in ...

We present 1 a technique to build and manipulate three dimensional models of vehicles, to be used by a computer vision system. These tools will help nd a suitable class of models for the vehicles and the trajectories, which are restricted to shape of cars (symmetry, regularity) and their trajectories (ground plane constraint), moving on a xed scenario. The models consist of a variable number of...

This article reports the results of a review of the research evidence related to joint working in the field of adult health and social care services in the UK. It explores whether recent reforms to joint working have met the objectives set by policy-makers. The review followed an established methodology: electronic databases were searched using predetermined terms, abstracts were screened again...

Formative assessments (FAs) can occur as preclass assignments, in-class activities, or postclass homework. FAs aim to promote student learning by accomplishing key objectives, including clarifying learning expectations, revealing student thinking to the instructor, providing feedback to the student that promotes learning, facilitating peer interactions, and activating student ownership of learn...

Responsiveness is a key objective of national health systems. Responsive health systems anticipate and adapt to existing and future health needs, thus contributing to better health outcomes. Of all the health systems objectives, responsiveness is the least studied, which perhaps reflects lack of comprehensive frameworks that go beyond the normative characteristics of responsive services. This p...

In this paper we present a framework for performance evaluation of a Bluetooth piconet using multislot packets. In particular, under some classical assumptions, we develop a model of a Bluetooth network and derive the complete statistics of the one–hop delay, and other significant metrics such as the channel utilization parameter. Stability conditions are investigated and it is shown that the u...
