Embedding Spatial Software Visualization in the IDE: an Exploratory Study
Software visualization can be of great use for understanding and exploring a
software system in an intuitive manner. Spatial representation of software is a
promising approach of increasing interest. However, little is known about how
developers interact with spatial visualizations that are embedded in the IDE.
In this paper, we present a pilot study that explores the use of Software
Cartography for program comprehension of an unknown system. We investigated
whether developers establish a spatial memory of the system, whether clustering
by topic offers a sound base layout, and how developers interact with maps. We
report our results in the form of observations, hypotheses, and implications.
Key findings are a) that developers made good use of the map to inspect search
results and call graphs, and b) that developers found the base layout
surprising and often confusing. We conclude with concrete advice for the design
of embedded software maps.Comment: To appear in proceedings of SOFTVIS 2010 conferenc
Critical knowledge map as a decision tool for knowledge transfer actions
Knowledge transfer is no longer reducible to classical solutions such as face-to-face training, technical education or tutoring. Knowledge to be transferred is professional knowledge (Business Knowledge). It involves the whole Knowledge Capital within an organization. Identifying the knowledge components that are worthwhile transferring is not an easy task. This is the problem addressed in this paper.Knowledge transfer, Knowledge Management, Knowledge mapping, Knowledge capitalization
The Community Structure of R&D Cooperation in Europe. Evidence from a social network perspective
The focus of this paper is on pre-competitive R&D cooperation across Europe, as captured by R&D joint ventures funded by the European Commission in the time period 1998-2002, within the 5th Framework Program. The cooperations in this Framework Program give rise to a bipartite network with 72,745 network edges between 25,839 actors (representing organizations that include firms, universities, research organizations and public agencies) and 9,490 R&D projects. With this construction, participating actors are linked only through joint projects.
In this paper we describe the community identification problem based on the concept of modularity, and use the recently introduced label-propagation algorithm to identify communities in the network, and differentiate the identified communities by developing community-specific profiles using social network analysis and geographic visualization techniques. We expect the results to enrich our picture of the European Research Area by providing new insights into the global and local structures of R&D cooperation across Europe
Development of Distributed Research Center for analysis of regional climatic and environmental changes
We present an approach and first results of a collaborative project being carried out by a joint team of researchers from the Institute of Monitoring of Climatic and Ecological Systems, Russia and Earth Systems Research Center UNH, USA. Its main objective is development of a hardware and software platform prototype of a Distributed Research Center (DRC) for monitoring and projecting of regional climatic and environmental changes in the Northern extratropical areas. The DRC should provide the specialists working in climate related sciences and decision-makers with accurate and detailed climatic characteristics for the selected area and reliable and affordable tools for their in-depth statistical analysis and studies of the effects of climate change. Within the framework of the project, new approaches to cloud processing and analysis of large geospatial datasets (big geospatial data) inherent to climate change studies are developed and deployed on technical platforms of both institutions. We discuss here the state of the art in this domain, describe web based information-computational systems developed by the partners, justify the methods chosen to reach the project goal, and briefly list the results obtained so far
Mapping London's Innovation Networks
A wide range of authors have highlighted the potential benefits for entrepreneurial companies that engage in effective networking along and across the supply-chain. As many organisations have downsized or outsourcedbasic research activities Universities have an increasingly important role within such networks. A number of UK initiatives have been established to encourage greater 'entanglement' between academia and commerce; the London Technology Network is one example which is intended to encourage interactions between London's leading research institutes and innovative businesses.Using the detailed data acquired by this network this paper is intended to presents an exploratory analysis of such activities with the aim of establishing the extent to which company size, sector and/or location play a significant role in participation in the network's activities.

Enhancing the water point mapping: a WASH approach
Strategic planning and appropriate development and management of water and sanitation services
can be strongly supported by accurate and accessible data. If adequately exploited, these data
might assist water managers with performance monitoring, benchmarking comparisons, policy
progress evaluation, resources allocation, and decision making. A variety of tools and techniques
are in place to collect such information. However, some methodological weaknesses arise when
developing an instrument for routine data collection, particularly at local level: (i) comparability
problems due to heterogeneity of
data and sector-re
lated indicators, (ii) in
adequate combination of
different information sources, and (iii) statistical validity of collected data.
The purpose of this study is to adopt an integrated water, sanitation and hygiene (WASH)
approach for data collection at community level in rural low income settings, as an attempt to
overcome previous shortcomings. The survey design takes the Water Point Mapping (WPM) as a
starting point to record all available water sources at a particular location, and this information is
then linked to data provided from a household-based survey. In order to demonstrate the
applicability of the method, a case study is presented at Tiraque Valley (Cochabamba, Bolivia).Peer ReviewedPostprint (published version
Quantitative Perspectives on Fifty Years of the Journal of the History of Biology
Journal of the History of Biology provides a fifty-year long record for
examining the evolution of the history of biology as a scholarly discipline. In
this paper, we present a new dataset and preliminary quantitative analysis of
the thematic content of JHB from the perspectives of geography, organisms, and
thematic fields. The geographic diversity of authors whose work appears in JHB
has increased steadily since 1968, but the geographic coverage of the content
of JHB articles remains strongly lopsided toward the United States, United
Kingdom, and western Europe and has diversified much less dramatically over
time. The taxonomic diversity of organisms discussed in JHB increased steadily
between 1968 and the late 1990s but declined in later years, mirroring broader
patterns of diversification previously reported in the biomedical research
literature. Finally, we used a combination of topic modeling and nonlinear
dimensionality reduction techniques to develop a model of multi-article fields
within JHB. We found evidence for directional changes in the representation of
fields on multiple scales. The diversity of JHB with regard to the
representation of thematic fields has increased overall, with most of that
diversification occurring in recent years. Drawing on the dataset generated in
the course of this analysis, as well as web services in the emerging digital
history and philosophy of science ecosystem, we have developed an interactive
web platform for exploring the content of JHB, and we provide a brief overview
of the platform in this article. As a whole, the data and analyses presented
here provide a starting-place for further critical reflection on the evolution
of the history of biology over the past half-century.Comment: 45 pages, 14 figures, 4 table
