A colleague and I recently proposed a model to guide the description and reform of mental health services and to clarify service evaluation (Tansella & Thornicroft, 1998). The model, which we call the ‘mental health matrix’, consists of two dimensions, one temporal and one geographical. The temporal dimension comprises three phases: input (phase A), process (phase B) and outcome (phase C). The ...

To answer this question section 2 motivates testing by providing a multidimensional view on what testing really is. Then in section 3 practices in testing regarding software architecture are presented which require active involvement and contributions by software architects. This results not only in better quality but also speeds up development by facilitating change and decreasing maintenance ...

A randomized-controlled study compared the preparatory effects of problem-posing on learning from subsequent instruction. Students engaged in problem-posing either with solution generation (where they generated problems and solutions to a novel situation) or problem-posing without solution generation (where they generated only problems) prior to learning a novel math concept. Problem-posing wit...

In this paper, we present the application of a set of software engineering roles. Role definitions were developed using internationally recognized software engineering reference documents for a major railway development organization: Bombardier Transportation. The description of the Software Architect role is explained. This paper will also illustrate how the role set could be used for project-...

The Dirichlet problem for the 2D Helmholtz equation in an exterior domain with cracks is studied. The compatibility conditions at the tips of the cracks are assumed. The existence of a unique classical solution is proved by potential theory. The integral representation for a solution in the form of potentials is obtained. The problem is reduced to the Fredholm equation of the second kind and of...

Employment is one of the bread-and –butter issues requiring urgent attention and careful handling. With the accelerating of the urbanization, a large number of surplus labors have appeared in rural areas of China. At the same time, in the course of the deepening reform of state-owned enterprises, there are more and more laid-off workers, so the problem of unemployment sticks out. In this paper,...

An inventory model for a deteriorating item with price sensitive demand is developed under deterioration rate, which is assumed to follow weibull distribution with known parameter. In addition, we allow for multiple price changes about an item, but the number of price changes isn’t given. The purpose of this paper is to find the optimal number of price settings, the optimal dynamic prices and t...

TRADITIONALLY, SOFTWARE architects were entrusted with making “decisions that are costly to change.”1 Because these decisions often had to be made early in the project, architects drew on their experience and ability to abstract to get them right. Repeated project cost and timeline overruns have demonstrated, though, that trying to plan all features and decide the system structure early in a pr...

The design studio 'Flying Bricks' was held during the summer semester 2015. Its main objective was to redesign an existing building with the use of facing bricks algorithmically, utilizing algorithmic thinking and programming as a means for form generation. The purpose of having students express their designs in terms of code was to emphasize problem thinking over solution generation, which has...

In an earlier column, I compared the roles of a software architect and a traditional building architect. I suggested that this oftenused analogy may not be entirely accurate, and that there may be a more precise analogy available to us in the emerging field of architectural engineering. In a subsequent release of SEI Interactive, Rick Kazman continued contrasting software architecture and “trad...
