    On the real world practice of Behaviour Driven Development

    Get PDF
    Surveys of industry practice over the last decade suggest that Behaviour Driven Development is a popular Agile practice. For example, 19% of respondents to the 14th State of Agile annual survey reported using BDD, placing it in the top 13 practices reported. As well as potential benefits, the adoption of BDD necessarily involves an additional cost of writing and maintaining Gherkin features and scenarios, and (if used for acceptance testing,) the associated step functions. Yet there is a lack of published literature exploring how BDD is used in practice and the challenges experienced by real world software development efforts. This gap is significant because without understanding current real world practice, it is hard to identify opportunities to address and mitigate challenges. In order to address this research gap concerning the challenges of using BDD, this thesis reports on a research project which explored: (a) the challenges of applying agile and undertaking requirements engineering in a real world context; (b) the challenges of applying BDD specifically and (c) the application of BDD in open-source projects to understand challenges in this different context. For this purpose, we progressively conducted two case studies, two series of interviews, four iterations of action research, and an empirical study. The first case study was conducted in an avionics company to discover the challenges of using an agile process in a large scale safety critical project environment. Since requirements management was found to be one of the biggest challenges during the case study, we decided to investigate BDD because of its reputation for requirements management. The second case study was conducted in the company with an aim to discover the challenges of using BDD in real life. The case study was complemented with an empirical study of the practice of BDD in open source projects, taking a study sample from the GitHub open source collaboration site. As a result of this Ph.D research, we were able to discover: (i) challenges of using an agile process in a large scale safety-critical organisation, (ii) current state of BDD in practice, (iii) technical limitations of Gherkin (i.e., the language for writing requirements in BDD), (iv) challenges of using BDD in a real project, (v) bad smells in the Gherkin specifications of open source projects on GitHub. We also presented a brief comparison between the theoretical description of BDD and BDD in practice. This research, therefore, presents the results of lessons learned from BDD in practice, and serves as a guide for software practitioners planning on using BDD in their projects

    The Public Performance Of Sanctions In Insolvency Cases: The Dark, Humiliating, And Ridiculous Side Of The Law Of Debt In The Italian Experience. A Historical Overview Of Shaming Practices

    Get PDF
    This study provides a diachronic comparative overview of how the law of debt has been applied by certain institutions in Italy. Specifically, it offers historical and comparative insights into the public performance of sanctions for insolvency through shaming and customary practices in Roman Imperial Law, in the Middle Ages, and in later periods. The first part of the essay focuses on the Roman bonorum cessio culo nudo super lapidem and on the medieval customary institution called pietra della vergogna (stone of shame), which originates from the Roman model. The second part of the essay analyzes the social function of the zecca and the pittima Veneziana during the Republic of Venice, and of the practice of lu soldate a castighe (no translation is possible). The author uses a functionalist approach to apply some arguments and concepts from the current context to this historical analysis of ancient institutions that we would now consider ridiculous. The article shows that the customary norms that play a crucial regulatory role in online interactions today can also be applied to the public square in the past. One of these tools is shaming. As is the case in contemporary online settings, in the public square in historic periods, shaming practices were used to enforce the rules of civility in a given community. Such practices can be seen as virtuous when they are intended for use as a tool to pursue positive change in forces entrenched in the culture, and thus to address social wrongs considered outside the reach of the law, or to address human rights abuses

    Assessing land administration systems with their legal frameworks: the case of peri-urban land in Ekiti State, Nigeria

    Get PDF
    The coexistence of customary and statutory law, tenure, and administration in peri-urban areas of sub-Saharan African (SSA) countries such as Nigeria may cause conflict and tension. An efficient and effective land administration systems (LASs) and legal frameworks are crucial for ensuring pro-poor objectives in land administration. Women, the vulnerable and the poor who are denied access to efficient and effective land administration services tend to experience tenure insecurity. Nigeria is one of the countries with an inefficient and ineffective LASs. The study explores the possibility of hybrid legal systems contributing to tenure insecurity in peri-urban areas of Southwest Nigeria. This study assesses customary and statutory laws and administration systems pertaining to Ekiti State, Nigeria to understand whether there is legal pluralism. A case study of customary and statutory laws, tenure, and administration was carried out using primary and secondary data. The study used three peri-urban cases from Ekiti State, Nigeria (Ikere-Ekiti, Ijero-Ekiti, and Oye-Ekiti) to learn how customary and statutory laws, tenure, and administration operate within the same geographical space. The study adopted Soft System Methodology (SSM), with two analytical frameworks: Responsible Land Management (RLM) and Fit-For-Purpose Land Administration (FFPLA). Moreover, the study used institutional isomorphism theory to determine the conflicting pressure exerted on the customary legal framework, comprising the customary courts and the Customary Court of Appeal of a State (CCAS). The LASs with their legal frameworks were assessed using text-based and empirical approaches. The study findings show weak and deep legal pluralism in LASs. The assessment leads to developing conceptual tools for assessing LASs with their legal frameworks. On the one hand, the conceptual tool for assessing LASs with their legal frameworks is based on the three pillars of human rights, the rule of law, and legal pluralism, taking a constitutional focus. The study findings revealed conflicting pressure exerted on customary courts and the Customary Court Appeal of a State (CCAS). On the other hand, the conceptual tool for measuring land tenure security based on three pillars of jurisdiction, legitimacy, and collaboration. The conceptual tools provide understanding of the influence of the hybrid legal system in LASs in peri-urban areas. The understanding of the influence of hybrid system is based on decentralising land administration activities, local land management, self-determination, and autonomy. The framework also incorporates legal and institutional flexibility. Areas of further research are recommended

    Machine Learning Algorithm for the Scansion of Old Saxon Poetry

    Get PDF
    Several scholars designed tools to perform the automatic scansion of poetry in many languages, but none of these tools deal with Old Saxon or Old English. This project aims to be a first attempt to create a tool for these languages. We implemented a Bidirectional Long Short-Term Memory (BiLSTM) model to perform the automatic scansion of Old Saxon and Old English poems. Since this model uses supervised learning, we manually annotated the Heliand manuscript, and we used the resulting corpus as labeled dataset to train the model. The evaluation of the performance of the algorithm reached a 97% for the accuracy and a 99% of weighted average for precision, recall and F1 Score. In addition, we tested the model with some verses from the Old Saxon Genesis and some from The Battle of Brunanburh, and we observed that the model predicted almost all Old Saxon metrical patterns correctly misclassified the majority of the Old English input verses

    Aiding the conservation of two wooden Buddhist sculptures with 3D imaging and spectroscopic techniques

    Get PDF
    The conservation of Buddhist sculptures that were transferred to Europe at some point during their lifetime raises numerous questions: while these objects historically served a religious, devotional purpose, many of them currently belong to museums or private collections, where they are detached from their original context and often adapted to western taste. A scientific study was carried out to address questions from Museo d'Arte Orientale of Turin curators in terms of whether these artifacts might be forgeries or replicas, and how they may have transformed over time. Several analytical techniques were used for materials identification and to study the production technique, ultimately aiming to discriminate the original materials from those added within later interventions
