  abstract: "The multitude of social media channels that programmers can use to participate in software development has given rise to online developer profiles that aggregate activity across many services. Studying members of such developer profile aggregators, we found an ecosystem that revolves around the social programmer. Developers are assessing each other to evaluate whether other developers are interesting, worth following, or worth collaborating with. They are self-conscious about being assessed, and thus manage their public images. They value passion for software development, new technologies, and learning. Some recruiters participate in the ecosystem and use it to find candidates for hiring; other recruiters struggle with the interpretation of signals and issues of trust. This mutual assessment is changing how software engineers collaborate and how they advance their skills."

  abstract: "Geschäft und IT wachsen insbesondere in SOA-Projekten immer stärker zusammen. Hierbei wird deutlich: prozess- als auch anforderungsbezogene Rollen versuchen dasselbe Problem zu lösen -- namentlich die Erhebung von Anforderungen und die Neudefinition der Unternehmung. Dies geschieht jedoch auf verschiedenen Ebenen und mit Hilfe unterschiedlicher Techniken. Da in Projekten bisher keine gegenseitige Unterstützung zwischen diesen beiden Rollen vorgesehen ist, sind redundant ausgeführte Tätigkeiten und Inkonsistenzen in der Spezifikation häufig die Folge. Die Anforderungen für SOA-Projekte könnten jedoch weitaus effizienter erhoben und verwaltet werden: durch eine verbesserte Koordination zwischen den verschiedenen Rollen, die Definition von Abhängigkeiten zwischen ihnen sowie die Fixierung der gegenseitig zu erbringenden Resultate. Eben jene Verzahung verlangt darüberhinaus eine Reihe unterstützender Techniken. Die schnellere Erhebung sowie die verbesserte Qualität der Anforderungen erhöhen die Agilität der Projekte und stärken so einen der Hauptvorteile von SOA."

  abstract: "Software ecosystems have become a new paradigm for the development of large-scale software, bringing a complex mixture of technical, business and social aspects. Although previous research has focused on understanding both the technical and business aspects, the social side of software ecosystems is less understood. To fill this gap, this paper presents the results of an empirical study aimed at understanding the influence of social aspects on the adoption and permanence of developers in software ecosystems. We conducted 25 interviews with software developers and we distributed an online questionnaire which included responses from 83 developers of mobile software applications. Using grounded theory techniques, we identified a complex social system based on continuous interaction and mutual support between different actors, including internal and external developers to the ecosystem, community developers, end users and businesses. Our results highlight the importance of social aspects in software ecosystems during the initial phase of adoption, as well as the continued participation of developers."

  abstract: "Gamification is the use of game elements in non-game context to engage and to motivate people to achieve goals. Its use is becoming very popular in software development organizations due to work being based upon human-centric and brain-intensive activity. This paper presents the topics of collaboration and gamification in the context of software engineering, and proposes a framework that identifies the most common collaboration issues that affect software development teams, and how to apply game elements to motivate a change on their behaviors."
