Scientometric Portrait of Homi Jehangir Bhabha: The Father of Indian Nuclear Research Programme
No full textQuantitative and qualitative analysis with graphic representation of the publication productivity of a scientist facilitates easy and clear perception about the work of a scientist. Bhabha’s scientific work spanned over more than three decades (1933-1967) during which he published 104 publications, which could be classified into nine fields: Interaction of Radiation with Matter (4), Quantum Electrodynamics (5), Mathematical Physics (2), Cosmic Ray Physics (18), Elementary Particle Physics (14), Field Theory (15), General Physics (2), Nuclear Physics (4) and General (40). The highest number of publications (6) were published in 1941, 1945 and 1964 respectively. The average number of publications published per year was 3.05. His productivity coefficient was 0.05 which is a clear indicates that his publication productivity was quite consistent throughout his scientific career. He was single author in 79 of his publications and the main author in 24 publications indicates that he always preferred to work himself and lead the team as ‘mentor’. Bhabha had 22 collaborators during the period. Team of research collaborators working with a successful scientist documents the sociological aspect of history of science while generating knowledge by a leader in a domain.
Bhabha became a citable author in 1937. Bhabha received 1211 citations to his 30 publications out of 104 publications. Out of 104, 74 publications did not receive any citations. Out of 74 publications, 40 publications dealt subjects mainly of general interest. Bhabha’s 86.66 percent of cited publications received their first citations within four years of their publication indicates that his publications were noticed immediately and had direct impact among the fellow researchers working all over the world. His overall citation rate was 11.64 per cited publication. The highest citations 389 were received to the domain ‘Cosmic ray physics’. The highest number of citations received were 45 in 1938. His self-citations were only 24 (1.98%) and citations by others were 1187 (98.02%). The highest self citations were six in 1946. Bhabha’s mean diachronous self-citation rate was 1.98. The highest citation rate 28.4 was to the domain ‘Quantum electrodynamics. His single authored publications have received the highest number 863 (71.26%) of citations. Bhabha’s five publications have been cited more than 100 times each. His publications have been cited by the authors working in various diverse fields like nuclear physics, mathematical physics, instrumentation, optics, geophysics and geochemistry, condensed matter physics, applied physics, electrical and electronic engineering, mechanical engineering etc., indicating a very diverse influence and impact of Bhabha’s publications. Bhabha’s publications have also been cited by the Nobel laureates like V. L. Ginzberg, Wolfgang Pauli, H. A. Bethe, M. Born, W. Bothe, E. P. Wigner, H. Yukawa, P. M. S. Blackett and C. N. Yang which is an indication of his originality of ideas and high quality of publications
The Maassilo towards a machine for exchange of culture: Working as a link between users, local and international culture
No full textBetween 1850 and 1900, the city of Rotterdam transformed into an international harbour city. In the twentieth century, the harbour rapidly grew larger to being the largest harbour in the world for over forty years. The first part of the Maassilo was built in the beginning of the twentieth century. As the harbour grew larger, the Maassilo expanded along, in search for the enormous scale that the harbour gained in this period. Nowadays, the Maassilo is centrally located in the urban neighbourhoods of the city, while the harbour its activity is concentrated further west. Future plans of Rotterdam are to develop the nineteenth and twentieth century harbours into cultural harbour areas. The goal of the project is to (re)connect four different layers with each other: the new users of the Maassilo (makers, collaborators and visitors); everything that is integrated with Rotterdam as a harbour city, especially elements that make the building a ‘machine’; the new local cultural context; and the international cultural context. By connecting these layers, the Maassilo can still be strongly connected with Rotterdam as a harbour city, and at the same time with the new urban, cultural harbour area in the future. The goal is to create space for makers, collaborators and visitors, whose energy and activities are the fuel for this machine building for local and international exchange of culture. The building is divided into three zones, for each group of users, with individual routing for visitors, artists, makers and collaborators. A central hall with daylight, organic shapes and warm materials, adds a warm heart to the rather harsh and cold concrete building, while also connecting the infrastructure and different zones inside the building with the urban infrastructure in the surrounding area. The Maassilo is initially designed for storage and exchange of grain, not for a large amount of visitors. The spaces where used to be infrastructure for (vertical) transport of grain, are reused in this design to make elevators and stairs for the new users. As a visitor to the exposition space, you can experience the route of the grain: visitors travel to the top floors with an elevator and can walk down with a spiralling staircase inside the silos. Even if the exposition space is completely empty, there still is an exposition. The space that visitors move through, is now also exposing the Maassilo. The large amount of silos of the Maassilo are not only interesting to move through as a visitor. The silos also pose interesting opportunities to play with acoustics in the designed music hall and could perhaps play a role in storage of energy as a buffer for the building and the surrounding area. With this design, the Maassilo attempts to be a link between Rotterdam as a port city and the new cultural harbour area in the future. While giving space to different groups of makers, collaborators and visitors, and for (international) exchange of all sorts of cultural activity.Architecture, Urbanism and Building Sciences | Heritage & Architectur
Evaluating the Synergic Effect of Collaboration in Information Seeking
No full textIt is typically expected that when people work together, they can often accomplish goals that are difficult or even impossible for individuals. We consider this notion of the group achieving more than the sum of all individuals' achievements to be the synergic effect in collaboration. Similar expectation exists for people working in collaboration for information seeking tasks. We, however, lack a methodology and appropriate evaluation metrics for studying and measuring the synergic effect. In this paper we demonstrate how to evaluate this effect and discuss what it means to various collaborative information seeking (CIS) situations. We present a user study with four different conditions: single user, pair of users at the same computer, pair of users at different computers and co-located, and pair of users remotely located. Each of these individuals or pairs was given the same task of information seeking and usage for the same amount of time. We then combined the outputs of single independent users to form artificial pairs, and compared against the real pairs. Not surprisingly, participants using different computers (co-located or remotely located) were able to cover more information sources than those using a single computer (single user or a pair). But more interestingly, we found that real pairs with their own computers (co-located or remotely located) were able to cover more unique and useful information than that of the artificially created pairs. This indicates that those working in collaboration achieved something greater and better than what could be achieved by adding independent users, thus, demonstrating the synergic effect. Remotely located real teams were also able to formulate a wider range of queries than those pairs that were co-located or artificially created. This shows that the collaborators working remotely were able to achieve synergy while still being able to think and work independently. Through the experiments and measurements presented here, we have also contributed a unique methodology and an evaluation metric for CIS.Peer reviewe
Sketching in HCI : Research practice & publication (Advanced)
No full textSketching in Human Computer Interaction is a valuable tool for subjective practice, but also a tool for engagement with collaborators, stakeholders, and participants. This hands-on practice can be utilised in a variety of contexts. The course enables those already in possession of sketching skills the confidence to take their work to the next level. Drawing from expertise gained by working in both academia and industry, the instructors will lead course attendees on a journey through practical applications of sketching in HCI, from subjective sketching to participant engagement and publishing, using hands on tasks and group activities. © 2020 Owner/Author

Collaborative Coupling over Tabletop Displays
No full textDesigning collaborative interfaces for tabletops remains difficult because we do not fully understand how groups coordinate their actions when working collaboratively over tables. We present two observational studies of pairs completing independent and shared tasks that investigate collaborative coupling, or the manner in which collaborators are involved and occupied with each other’s work. Our results indicate that individuals frequently and fluidly engage and disengage with group activity through several distinct, recognizable states with unique characteristics. We describe these states and explore the consequences of these states for tabletop interface design.

Students' perceptions of issues arising from and factors influencing group interaction in computer conferencing : a grounded theory approach.
No full textThe present study aimed to identify students' perceptions of issues arising from and factors influencing on-line group interaction and dynamics in computer conferencing in higher education by recording the perceptions of a group of students who acted as members of on- line groups. The emergent objectives were to develop recommendations and guidelines for the effective deployment of on-line group interaction and elements of a possible model. The research has taken an inductive interpretative approach applying qualitative methods. Interviews were the main tool of data collection and the grounded theory approach, as developed by Strauss and Corbin in 1990, adopted for the analysis of the interview data. The analysis was also assisted by the use of the Atlas. ti software, specially designed for analysis of qualitative data. Issues of validity of qualitative research, following Lincoln and Guba's (1985) proposed criteria of establishing "trustworthiness" such as credibility, transferability, dependability and confirmability were addressed and discussed in connection to the current study. Findings of the study were placed around five main categories addressing ways group participants utilised in order to express themselves in the computer conferencing environment, issues of participation, decision-making procedures, conflicts and disagreements, and finally co-ordination issues. A number of factors affected the categories arose were identified. Relationships between the categories proposed and the code named lack of communication cues were also identified. Conclusions drawn from the study formulated guidelines and recommendations on computer conferencing issues and factors found to affect interaction among the group participants in the text-based on-line environment and proposed elements of a theory following the grounded theory procedures. Suggestions and points for further research along with implications for practice were also included
"Your side of the street": Cormac McCarthy's collaborative authorship
No full textIn this thesis I investigate the relationship between contemporary author Cormac McCarthy and his editors: Albert Erskine at Random House and Gary Fisketjon and Dan Frank at Alfred A Knopf. In investigating these relationships I attempt to give insight into the working practices of McCarthy, and by doing so examine the changing world of publishing at Random House. I also explore the implications for established critical understandings of McCarthy's work of the significant changes which were made during the re-writing and editing of McCarthy's novels. In mapping relationships between author, editor and agent I conduct a study of the changing modes and models of author-editor and author-editor-agent relationships within Random House and its subsidiary Alfred A Knopf. Taking each of McCarthy's novels in turn as a case study I construct an examination of the relationships between this tightly knit core group and the various specialist collaborators who appear at scattered but significant moments during McCarthy's literary career. It is in this web of collaboration and interdependence in concert with established understandings of the author-role and author-function that this thesis builds its understanding of McCarthy's authorship practices.
In this thesis I draw intensively upon archival material held at both the University of Texas at San Marcos, where McCarthy's own papers are held following their sale to the Witliff South Western Writers Collection, and the papers of Albert Erskine, currently held at the University of Virginia as part of their Small Special Collections Archive. Between the two archives, this body of material contains personal and professional correspondence between McCarthy and his various collaborators, as well as McCarthy's handwritten notebooks in which he made copious notes from his various source books and, most significantly, the various typewritten drafts and redrafts of all of McCarthy's novels. These drafts include handwritten notes from both McCarthy himself as he altered the typescripts during the redrafting process and those of his editors, who annotated the various drafts McCarthy sent them in order to suggest changes or ask questions about various aspects of the drafts. Through an engagement with these valuable sources of unpublished primary material I attempt in this thesis to resituate the input of McCarthy's editor and other collaborators into an understanding of McCarthy's work
