An investigation into computer support for cooperative work in software engineering groups

The research of this thesis relates to Computer Supported Cooperative Work (CSCW) in the context of software engineering, and in particular software engineering education. Whilst research into group working has tended to be directed towards CSCW, very little research has been undertaken on group working within software engineering. Linked with CSCW is groupware, which is the class of tools that supports and augments groupwork. This thesis represents an attempt to contribute to the understanding of the groupware needs of software engineers, and to identify and trial groupware that supports software engineering activities. An infrastructure has been developed providing virtual environments, for use by both collocated and geographically distributed software engineering students, to support their groupwork. This infrastructure comprises of synchronous and asynchronous groupware, in the form of desktop video conferencing, and a shared information workspace. This shared workspace has been tailored from the groupware tool, Basic Support for Cooperative Work (BSCW).Within this thesis, hypotheses have been formulated as to the student use of these virtual environments. These hypotheses concentrate on the areas of: organisation and coordination of tasks, the level of cooperation that occurs within the phases of the software lifecycle, the usage of the functions within a shared workspace, and what importance is placed on the role of synchronous communication within software engineering student groupwork. Through a series of case studies it was possible to determine the outcome of these hypotheses using various data collection methods. These methods include questionnaires, focus group meetings, observations, and automatic monitoring of workspace activities. The outcomes of this thesis are that the hypotheses regarding organisation and coordination, and, the role of synchronous communication within software engineering, have been proved. Whilst the determination of the level of cooperation during the phases of the software lifecycle has not been proved, the use of functions within the shared workspace has been partly proved

Survivor: An Approach for Adding Dependability to Legacy Workflow Systems

Although they often provide critical services, most workflow systems are not dependable. There has been much literature on dependable/survivable distributed systems; most is concerned with developing new architectures, not adapting pre-existing ones. Additionally, the literature is focused on hardening, security-based defense, as opposed to recovery. For deployed systems, it is often infeasible to completely replace existing infrastructures; what is more pragmatic are ways in which existing distributed systems can be adapted to offer better dependability. In this paper, we outline a general architecture that can easily be retrofitted to legacy workflow systems in order to improve dependability and fault tolerance. We do this by monitoring enactment and replicating partial workflow states as tools for detection, analysis and recovery. We discuss some policies that can guide these mechanisms. Finally, we describe and evaluate our implementation, Survivor, which modified an existing workflow system provided by the Naval Research Lab

Using fuzzy sets to analyse personal preferences on groupware tools

When stakeholders are geographically distributed communication presents new challenges for software engineering community. In order to improve communication between stakeholders, we have previously proposed to apply learning style models to characterise the way people interact. In this work we enhance that model, using fuzzy reasoning, to find a set of rules that tell us which groupware tools are more suitable according to stakeholders classification.Eje: I - Workshop de Ingeniería de Software y Base de DatosRed de Universidades con Carreras en Informática (RedUNCI

Collaborative problem solving and program development model

A model to enhance collaborative problem solving and program development is presented. The collaborative model is a detailed cognitive model that takes into consideration the cognitive and social activities that occur during collaborative problem solving and program development. The cognitive activities required for collaborative problem solving and program development are identified and integrated into a six-stage model. An extensive literature review in the associated fields is presented to show the need for the model described in this dissertation. In addition, a comprehensive study of tools to support collaboration during problem solving and program development was also performed as well as a critique of these tools. A detailed statistical experiment to study the effect of this model on subjects, collaboratively solving a software problem was designed and executed. The experiment included testing the collaborative problem solving and program development model with and without assistance from groupware tools. The subject teams each constructed a software design and this design was evaluated based on, research hypotheses. This experiment produced results indicating the positive effect the Collaborative Model has on problem understanding and the quality of solution planning during collaborative problem solving and program development efforts

Learn-ciam: a model-driven approach for the development of collaborative learning tools

This paper introduces Learn-CIAM, a new model-based methodological approach for the design of flows and for the semi-automatic generation of tools in order to support collaborative learning tasks. The main objective of this work is to help professors by establishing a series of steps for the specification of their learning courses and the obtaining of collaborative tools to support certain learning activities (in particular, for in-group editing, searching and modeling). This paper presents a complete methodological framework, how it is supported conceptually and technologically, and an application example. So to guarantee the validity of the proposal, we also present some validation processes with potential designers and users from different profiles such as Education and Computer Science. The results seem to demonstrate a positive reception and acceptance, concluding that its application would facilitate the design of learning courses and the generation of collaborative learning tools for professionals of both profiles

Online Deliberation: Design, Research, and Practice

Can new technology enhance purpose-driven, democratic dialogue in groups, governments, and societies? Online Deliberation: Design, Research, and Practice is the first book that attempts to sample the full range of work on online deliberation, forging new connections between academic research, technology designers, and practitioners. Since some of the most exciting innovations have occurred outside of traditional institutions, and those involved have often worked in relative isolation from each other, work in this growing field has often failed to reflect the full set of perspectives on online deliberation. This volume is aimed at those working at the crossroads of information/communication technology and social science, and documents early findings in, and perspectives on, this new field by many of its pioneers.

Understanding the voluntary moderation practices in live streaming communities

Harmful content, such as hate speech, online abuses, harassment, and cyberbullying, proliferates across various online communities. Live streaming as a novel online community provides ways for thousands of users (viewers) to entertain and engage with a broadcaster (streamer) in real-time in the chatroom. While the streamer has the camera on and the screen shared, tens of thousands of viewers are watching and messaging in real-time, resulting in concerns about harassment and cyberbullying. To regulate harmful content—toxic messages in the chatroom, streamers rely on a combination of automated tools and volunteer human moderators (mods) to block users or remove content, which is termed content moderation. Live streaming as a mixed media contains some unique attributes such as synchronicity and authenticity, making real-time content moderation challenging. Given the high interactivity and ephemerality of live text-based communication in the chatroom, mods have to make decisions with time constraints and little instruction, suffering cognitive overload and emotional toll. While much previous work has focused on moderation in asynchronous online communities and social media platforms, very little is known about human moderation in synchronous online communities with live interaction among users in a timely manner. It is necessary to understand mods’ moderation practices in live streaming communities, considering their roles to support community growth. This dissertation centers on volunteer mods in live streaming communities to explore their moderation practices and relationships with streamers and viewers. Through quantitative and qualitative methods, this dissertation mainly focuses on three aspects: the strategies and tools used by moderators, the mental model and decision-making process applied toward violators, and the conflict management present in the moderation team. This dissertation uses various socio-technical theories to explain mods’ individual and collaborative practices and suggests several design interventions to facilitate the moderation process in live streaming communities
