Abstract
Quality assessment of open source software is becoming an important and active research area. One of the reasons for this recent interest is the consequence of Internet popularity. Nowadays, programming also involves looking for the large set of open source libraries and tools that may be reused when developing our software applications. In order to reuse such open source software artifacts, programmers not only need the guarantee that the reused artifact is certified, but also that independently developed artifacts can be easily combined into a coherent piece of software. In this paper we describe a domain specific language that allows programmers to describe in an abstract level how software artifacts can be combined into powerful software certification processes. This domain specific language is the building block of a web-based, open-source software certification portal. This paper introduces the embedding of such domain specific language as combinator library written in the Haskell programming language. The semantics of this language is expressed via attribute grammars that are embedded in Haskell, which provide a modular and incremental setting to define the combination of software artifacts.

Abstract
For museums, developing audiences means both attracting non-visitors to their venues, and improving repeat visitors' attendance patterns and experience. Audience development strategies encourage museums to create open door events in order to deal with barriers preventing a wider audience from becoming their visitors, and to build stronger relationships with their current visitors. Satisfaction is expected to influence future buying decisions - i.e., intention to return and to recommend. Will a satisfying experience at a museum event improve event goers' visiting patterns? This research aims to ascertain the effects of attending open day events on the development of art museum audiences. We present the findings of exploratory quantitative research using the personal interview survey method. Our results indicate that open day events have potential to develop audiences, as such events eliminate attendance barriers, attract first time visitors and provide trial experiences for potential museum visitors. However, the positive association between event experience and intention to return to the museum on an ordinary day was not statistically supported by this study. © 2012 Copyright Taylor and Francis Group, LLC.

Abstract
In this paper we analyze the stochastic version of a minimalistic multi-strain model, which captures essential differences between primary and secondary infections in dengue fever epidemiology, and investigate the interplay between stochasticity, seasonality and import. The introduction of stochasticity is needed to explain the fluctuations observed in some of the available data sets, revealing a scenario where noise and complex deterministic skeleton strongly interact. For large enough population size, the stochastic system can be well described by the deterministic skeleton gaining insight on the relevant parameter values purely on topological information of the dynamics, rather than classical parameter estimation of which application is in general restricted to fairly simple dynamical scenarios.

Abstract
The tweens are a transitional age group undergoing deep physical and psychological transformations. Based on a thirteen-focus group research design involving 103 students, and applying a tweens-centered approach, the characteristics of SMS, IM, Internet, digital photos, electronic games, and email were analyzed. Categories such as moral issues, psychological and social consequences, problems/drawbacks, general benefits, and technical attributes synthesized the main characteristics attached to each form of digital technology. Their relative relevance was not gender dependent. Furthermore, tweens exhibited both metacognitive knowledge and personal epistemological observations associated with most of the digital technologies.
