Ecosystem research has thus far focused on understanding the structure and dynamics of already existing ecosystems. However much less attention has been devoted to the emergence of ecosystems. I first theoretically develop an institutional approach to ecosystems, arguing that the ecosystem is an organisational field which has value co-creation as its recognised area of institutional life. Synthesising the theories of dominant design, social movements, and institutional entrepreneurship, I identify four activities that drive the processes of ecosystem emergence: resource, technological, institutional and contextual activities. Empirically, I compare the emergence sequences of six digital service ecosystems – Amazon, eBay, Facebook, Google, Salesforce and Wikipedia – using a narrative explanation methodology, applying event colligation, optimal matching, direct inspection, frequency analysis and an innovative statistical bootstrapping technique. I find that emergence sequences of each case are significantly dissimilar and that there are three phases of emergence – Initiation, Momentum, Control. The first of these phases is similar across cases, but subsequent phases exhibit increasing dissimilarity as the ecosystem evolves and takes on idiosyncratic characteristics. To explain these findings, I develop an ecosystem perspective that explicitly integrates value co-creation processes as an important regulator of the evolution of ecosystems. I suggest that idiosyncratic logics of value co-creation result in differing value creation processes. I show that the three distinct phases of ecosystem emergence form a coherent, distinctive whole when considered from the perspective of value co-creation. Emphasising that value appropriated must first be co-created, I propose the ‘ecosystem model’ as an analytic tool to better conceptualise value co-creation and appropriation in ecosystems. I discuss the implications of these contributions for ecosystem research, institutional theory, and strategic management practice. 7 8 ACKNOWLEDGEMENTS Profound gratitude is due to both my supervisors, Professor David Gann and Professor Erkko Autio. Their guidance and forbearance has been peerless in my transition from a management consultant with an MBA to a future career in academia. David provided the mental bridge between industry and academia, suggested the first realistic formulations of the research question, and instilled the requirements for a doctorate. Erkko, more research focused, provided the patience and support in developing the theoretical, methodological and empirical contributions. Of particular note are the many casual chats in his office discussing various knotty conundrums; this thesis would not be what it is if not for Erkko’s efforts. I am also thankful for the conversations I have had with Markus Perkmann, who has provided a refreshing alternative view at difficult moments. I further thank David and Erkko for their confidence in me through the co-authorship of a paper (separate to this thesis) that has been conditionally accepted by the Academy of Management Perspectives, as well as a number of working papers (also separate to this thesis) that will hopefully go further. I also thank Erkko for our jointly authored chapter in The Oxford Handbook of Innovation Management. Virginia Harris, David’s PA, has been incredible in arranging supervisory meetings with such busy people. Without her efforts there would have been significantly less supervision. I also thank Julie Paranics, the former Doctoral Programme Manager at Imperial Business School, for all of her assistance and support during my time in the doctoral programme. I thank the EPSRC for providing the funding to undertake these studies. My fellow doctoral students have also provided for many interesting and varied conversations over the years. Attempting a PhD is challenging at the best of times, and being able to bounce ideas and difficulties of like-minded colleagues has been a boon. I particularly thank Matthew Cleeveley and Katherine Lovell for their patience. Last, but most certainly not least, heartfelt thanks must also go to my ever-patient wife, Isabel. As well as bringing into the world our two beautiful children – Hydra and Guillem – during these studies, she has kept the family operational, held down a demanding job, and handled a distracted husband. This thesis would not have happened if not for her. 9 10 TABLE OF CONTENTS DECLARATION .................................................................................................................................... 5 ABSTRACT ............................................................................................................................................ 7 ACKNOWLEDGEMENTS .................................................................................................................... 9 TABLE OF CONTENTS ...................................................................................................................... 11 LIST OF TABLES ................................................................................................................................ 14 LIST OF FIGURES .............................................................................................................................. 16 1 INTRODUCTION ...................................................................................................................... 17 1.1 Research questions and approach ..................................................................................... 21 1.2 Method and data ............................................................................................................... 21 1.3 Structure of the thesis ....................................................................................................... 23 2 THE ECOSYSTEM AS AN ORGANISATIONAL FIELD ...................................................... 25 2.1 Characteristics of an ecosystem ........................................................................................ 25 2.1.1 Value-creating networks ....................................................................................... 26 2.1.2 Governance system ............................................................................................... 28 2.1.3 A shared logic ....................................................................................................... 29 2.2 Models of organisational collectivities in organisation theory ......................................... 31 2.2.1 Resource dependence theory models .................................................................... 34 2.2.2 Organisational ecology models ............................................................................. 37 2.2.3 Institutional models ............................................................................................... 38 2.3 The ecosystem as a fifth facet .......................................................................................... 42 2.4 Conclusion ........................................................................................................................ 47 3 ACTIVITIES OF ECOSYSTEM EMERGENCE ...................................................................... 48 3.1 Dominant design theory ................................................................................................... 50 3.2 Social movement theory ................................................................................................... 54 3.3 Institutional entrepreneurship ........................................................................................... 59 3.4 Four activities of ecosystem emergence ........................................................................... 62 3.4.1 Resource activities ................................................................................................ 65 3.4.2 Technological activities ........................................................................................ 69 3.4.3 Institutional activities ............................................................................................ 70 3.4.4 Contextual activities .............................................................................................. 73 3.5 Conclusion .......................................................................................................................

    Source Code Stylometry and Authorship Attribution for Open Source by Daniel Watson A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Mathematics in Computer Science Waterloo, Ontario, Canada, 2019 c Daniel Watson 2019 Author's Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract Public software repositories such as GitHub make transparent the development history of an open source software system. Source code commits, discussions about new features and bugs, and code reviews are stored and carefully attributed to the appropriate developers. However, sometimes governments may seek to analyze these repositories, to identify citi- zens who contribute to projects they disapprove of, such as those involving cryptography or social media. While developers who seek anonymity may contribute under assumed identi- ties, their body of public work may be characteristic enough to betray who they really are. The ability to contribute anonymously to public bodies of knowledge is extremely impor- tant to the future of technological and intellectual freedoms. Just as in security hacking, the only way to protect vulnerable individuals is by demonstrating the means and strength of available attacks so that those concerned may know of the need and develop the means to protect themselves. In this work, we present a method to de-anonymize source code contributors based on the authors' intrinsic programming style.

It is with many hours. In order to encourage students to put in these hours, these ideas in mind that we conceived Code Hunt, a game for we built Code Hunt, a game that enables players to program coding against the computer by solving a sequence of puzzles against the computer with clues provided as unit tests. The game of increasing complexity. Code Hunt is unique among coding has become very popular and we are now running worldwide systems and among games in that it combines the elements of contests where students have a fixed amount of time to solve a set of puzzles. This paper describes Code Hunt and the contest both to produce just what we need to get students to put in those experience it offers. We then show some early results that hours of practice to hone their programming skills.

    On the Feasibility of Malware Authorship Attribution Saed Alrabaee, Paria Shirani, Mourad Debbabi, and Lingyu Wang Concordia University, Montreal, Canada Abstract. There are many occasions in which the security community is interested to discover the authorship of malware binaries, either for digital forensics analysis of malware corpora or for thwarting live threats of malware invasion. Such a discovery of authorship might be possible due to stylistic features inherent to software codes written by human programmers. Existing studies of authorship attribution of general pur- pose software mainly focus on source code, which is typically based on the style of programs and environment. However, those features critically depend on the availability of the program source code, which is usually not the case when dealing with malware binaries. Such program binaries often do not retain many semantic or stylistic features due to the compila- tion process. Therefore, authorship attribution in the domain of malware binaries based on features and styles that will survive the compilation process is challenging. This paper provides the state of the art in this literature. Further, we analyze the features involved in those techniques. By using a case study, we identify features that can survive the compi- lation process. Finally, we analyze existing works on binary authorship attribution and study their applicability to real malware binaries. 1 Introduction Authorship attribution comprises an important aspect of many forensic investi- gations, which is equally true in the computer world. When a malware attacks computer systems and leaves behind a malware corpus, an important question to ask is 'Who wrote this malware?'.

  • Forest for the Trees for Adversarial Code Stylometry
    StyleCounsel: Seeing the (Random) Forest for the Trees in Adversarial Code Stylometry by Christopher McKnight A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Mathematics in Computer Science Waterloo, Ontario, Canada, 2018 c Christopher McKnight 2018 I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract Authorship attribution has piqued the interest of scholars for centuries, but had historically remained a matter of subjective opinion, based upon examination of handwriting and the physical document. Midway through the 20th Century, a technique known as stylometry was developed, in which the content of a document is analyzed to extract the author’s grammar use, preferred vocabulary, and other elements of compositional style. In parallel to this, programmers, and particularly those involved in education, were writing and testing systems designed to automate the analysis of good coding style and best practice, in order to assist with grading assignments. In the aftermath of the Morris Worm incident in 1988, researchers began to consider whether this automated analysis of program style could be combined with stylometry techniques and applied to source code, to identify the author of a program. The results of recent experiments have suggested this code stylometry can successfully iden- tify the author of short programs from among hundreds of candidates with up to 98% precision. This potential ability to discern the programmer of a sample of code from a large group of possible authors could have concerning consequences for the open-source community at large, particularly those contributors that may wish to remain anonymous.
