Faculty Seminar On Collaboration Syllabus
This is a collectively-built, in-progress syllabus for a faculty seminar on the topic of collaboration at Swarthmore College, Spring 2016. Topics include competing definitions of collaboration across disciplines, formal and informal collaboration, rich descriptions of collaboration, metrics and measures of collaborations, digital and analog tools for collaboration, literary and historical forms of collaboration, cost/benefit analyses of collaboration, crossinstitutional collaborations, institutional versus individual collaborations, collaboration narratives, failed or tragic collaborations, and teaching collaborations. Seminar members include statisticians, historians, psychologists, visual artists, literary critics, physicists, philosophers, engineers, education studies researchers, linguists, art historians, and computer scientists. Our format will accommodate both discussions of readings based on the syllabus as well as small experiments, and planning for possible future related projects
Privacy-Friendly Collaboration for Cyber Threat Mitigation
Sharing of security data across organizational boundaries has often been
advocated as a promising way to enhance cyber threat mitigation. However,
collaborative security faces a number of important challenges, including
privacy, trust, and liability concerns with the potential disclosure of
sensitive data. In this paper, we focus on data sharing for predictive
blacklisting, i.e., forecasting attack sources based on past attack
information. We propose a novel privacy-enhanced data sharing approach in which
organizations estimate collaboration benefits without disclosing their
datasets, organize into coalitions of allied organizations, and securely share
data within these coalitions. We study how different partner selection
strategies affect prediction accuracy by experimenting on a real-world dataset
of 2 billion IP addresses and observe up to a 105% prediction improvement.Comment: This paper has been withdrawn as it has been superseded by

Measuring collaborative emergent behavior in multi-agent reinforcement learning
Multi-agent reinforcement learning (RL) has important implications for the
future of human-agent teaming. We show that improved performance with
multi-agent RL is not a guarantee of the collaborative behavior thought to be
important for solving multi-agent tasks. To address this, we present a novel
approach for quantitatively assessing collaboration in continuous spatial tasks
with multi-agent RL. Such a metric is useful for measuring collaboration
between computational agents and may serve as a training signal for
collaboration in future RL paradigms involving humans.Comment: 1st International Conference on Human Systems Engineering and Design,

Searching Research Excellence: An in-depth bibliometric analysis of the international research contribution of the University of Granada
The main goal of this report is to offer a comprehensive portray of the research performance and impact of the University of Granada. It presents a bibliometric longitudinal analysis for the 1980-2013 time period, including bibliometric indicators for 195 subject categories. Hence showing a general analysis and specific analyses by subjects. These 195 analyses by subjects show the strengths and weaknesses of the research system. Thus, the reader may identify the disciplines in which the University of Granada currently or historically has been more productive or had a greater impact. These disciplines comprise four broad areas: Humanities & Social Sciences, Engineering & Technology, Exact & Natural Sciences, and Life & Health Sciences. The report is directed to the academic staff of the University of Granada. Its objective is to show the state of research at the university in an accurate and reliable fashion. There is a brief bibliometric report for each subject category which showcases research trends, bibliometric indicators and a list of the most productive researchers.Universidad de Granada.

Opportunities and challenges in designing a blended international student project activity: Experiences from the EPIC project
In this paper we explain our experiences and observations on a blended international teaching/training student project activity designed for students of different academic levels and programs at different universities working together on a project given by an industrial partner. This project activity is designed based on the EPIC project, funded by the Erasmus+ programme of the European Commission, which aims to provide a framework for carrying out multi-cultural and multidisciplinary student projects for increasing employability in an international job market.Peer ReviewedPostprint (author's final draft
Providing behaviour awareness in collaborative project courses
Several studies show that awareness mechanisms can contribute to enhance the collaboration process among students and the learning experiences during collaborative project courses. However, it is not clear what awareness information should be provided to whom, when it should be provided, and how to obtain and represent such information in an accurate and understandable way. Regardless the research efforts done in this area, the problem remains open. By recognizing the diversity of work scenarios (contexts) where the collaboration may occur, this research proposes a behaviour awareness mechanism to support collaborative work in undergraduate project courses. Based on the authors previous experiences and the literature in the area, the proposed mechanism considers personal and social awareness components, which represent metrics in a visual way, helping students realize their performance, and lecturers intervene when needed. The trustworthiness of the mechanisms for determining the metrics was verified using empirical data, and the usability and usefulness of these metrics were evaluated with undergraduate students. Experimental results show that this awareness mechanism is useful, understandable and representative of the observed scenarios.Peer ReviewedPostprint (published version

Constructing Temporal Networks of OSS Programming Language Ecosystems
One of the primary factors that encourage developers to contribute to open
source software (OSS) projects is the collaborative nature of OSS development.
However, the collaborative structure of these communities largely remains
unclear, partly due to the enormous scale of data to be gathered, processed,
and analyzed. In this work, we utilize the World Of Code dataset, which
contains commit activity data for millions of OSS projects, to build
collaboration networks for ten popular programming language ecosystems,
containing in total over 290M commits across over 18M projects. We build a
collaboration graph representation for each language ecosystem, having authors
and projects as nodes, which enables various forms of social network analysis
on the scale of language ecosystems. Moreover, we capture the information on
the ecosystems' evolution by slicing each network into 30 historical snapshots.
Additionally, we calculate multiple collaboration metrics that characterize the
ecosystems' states. We make the resulting dataset publicly available, including
the constructed graphs and the pipeline enabling the analysis of more
ecosystems.Comment: Accepted to SANER 202
Geoscience studies in the Maltese Islands: a gateway to the Central Mediterranean region
The location of the Maltese Islands, at the centre of the Mediterranean Sea, places them as a reference for regional climatic, tectonic and marine processes that have affected the Mediterranean basin. Our review work targeted the entire geoscientific literature produced about the Maltese Islands, covering the period from the 19th century to 2023. We identified ca. 390 papers, by using the main literature databases, and classified them according to the main scientific fields. Geomorphology, stratigraphy and sedimentology represent the main research topics, followed by palaeontology and structural geology. We analysed the temporal distribution of this scientific production, highlighting an overall increasing trend in the number of papers over time. This reveals a growing interest in the geoscientific research related to the Maltese Islands. The review emphasises collaborative efforts between scientists from different fields, illustrating the interdisciplinary nature of geoscientific research in Malta. Our results show that the scientific collaboration between authors, and affiliated institutions, is also based on the shared history and linguistic ties, among the Maltese, Italian and British cultures. The outputs of our review aim to be a comprehensive reference for those undertaking geoscientific research on the Islands
