Abstract
Chromosomal inversions can originate from breakage and repair by non-homologous end-joining. Nevertheless, they can also originate from ectopic recombination between transposable elements located on the same chromosome inserted in opposite orientations. Here, we show that a MITE element (DAIBAM), previously involved in the origin of one Drosophila americana polymorphic inversion, is also involved in the origin of one fixed inversion between D. virilis and D. americana and another D. americana polymorphic inversion. Therefore, DAIBAM is responsible for at least 20% of the chromosomal rearrangements that are observed within and between species of the virilis phylad (D. virilis, D. lummei, D. novamexicana and D. americana), having thus played a significant role in the chromosomal evolution of this group of closely related species.

Abstract
The reality in today's business is to compete with dynamic and shorter market opportunities. In order to cope up with such environment, manufacturing firms, especially small and medium size enterprises (SMEs) are needed to collaborate with each other for mutual benefits. This collaboration offers process enhancement within the environment of virtual enterprise (VE) and contributes towards sharing costly resources and valuable knowledge among manufacturing companies. This research is basically focused on the process collaboration among companies that motivates them achieving identified business opportunities. A collaboration framework is proposed in this paper with respect to VE process mapping. Visualization of such processes is also highlighted though 'Dashboard' user interfaces in order to monitor and control a successful VE.

Abstract
The art of telling stories in digital format is currently widely available due to the popularization of digital cameras, computers and other mobile devices. In this paper we discuss the use of collaborative learning strategies based on Digital Storytelling in corporative training. The text includes a concise review on theoretical and technical foundations about educational communication through the use of audiovisual products based on disciplines such as Communication, Education and Cognitive Sciences. We will also discuss how Digital Storytelling may be integrated in traditional contents oriented self-training systems, used by many corporations. However the main focus will be the discussion of the potential of the use of Digital Storytelling methodology in corporative training context which will be detailed based on data collected in scenarios from Portugal and Brazil. The paper is based on qualitative research and it will argue that digital storytelling may contribute to the improvement of the effectiveness of collaborative learning processes in corporative training, because it provides means for the swift delivery of highly contextualized learning materials and the sharing of relevant personal trainers and trainees’ experiences. Furthermore, Digital Storytelling methodology provides an opportunity to value, respect and promote the multiple and different cultural and social interactions in the corporative knowledge construction process. The research methodology adopted on this study involved three phases: 1) literature review; 2) detailed analysis of the digital Storytelling methodology and its implications in corporative training context; 3) collecting data from and discussing about some corporative cases in Portugal and Brazil. The result of the research aims at suggesting a critical analysis and creative attitude in the production of audiovisual teaching materials for the corporative training context.
