Reaching the Unreached: Community Based Village Knowledge Centres and Village Resources Centres
No full textThe book explores the history, initiatives and achievements of the M. S. Swaminathan Research Foundation (MSSRF). These include the bio-village initiative, designed to encourage the development of market driven on-farm and non-farm enterprises, and unskilled to skilled work through the sustainable use of natural resources; as well as the Village Through the VKCs (Village Knowledge Centres). The aim is to bridge the digital divide and thus address social exclusion and poverty associated with it. Through Village Resource Centres and VKC information and technology communication for development (ICT4D) strategies many communities in India have been positively impacted

Large scale horizontal cylinder forces in waves and currents
No full textThis paper describes laboratory measurements of forces and pressures on smooth and rough horizontal cylinders of diameters 0.21m and 0.5m beneath waves of heights up to 1.9m, in the presence of currents up to Im/s in either direction. Drag and inertia coefficients evaluated on a wave-by-wave basis exhibited very wide scatter, but average values over all Keulegan Carpenter numbers were found insensitive to currents and gave predictions of the largest peak horizontal forces to within 16% of the measurements in 90% of cases in irregular waves. Vertical forces deviated much more strongly from Morison predictions owing to vortex shedding, and to slowly-varying forces due to the Magnus effect associated with wave-induced circulation.<br/

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Loading on a vertical cylinder in multidirectional waves
No full textThis paper presents laboratory measurements of local and total loading on an isolated vertical cylinder in irregular unidirectional and multidirectional waves. Maximum Keulegan-Carpenter numbers in individual waves were about 16, and maximum Reynolds numbers about 3 × 104. It is shown that in these conditions, existing theoretical and numerical models underestimate the reduction in loading on a cylinder due to wave spreading. Besides the changes that are predicted when Morison's equation is used with constant coefficients, there are hydrodynamic influences that contribute further force reductions. Comparisons with Dean's (1977) hybrid approach suggest that in the present conditions these reductions are in the region of 3 and 6 percent for a spreading function cos2s , with s = 8 and s = 2, respectively. Larger reductions can be expected at higher Keulegan-Carpenter numbers, though scale effects are likely to become more important in the drag-dominated regime
MoS2 coated CoS2 nanocomposites as counter electrodes in Pt-free dye-sensitized solar cells
No full textExpensive Pt counter electrodes remain an obstacle for the commercialization of dye-sensitized solar cells (DSSCs). Therefore, research focusing on low-cost alternative counter electrode materials has been considered important for their commercialization. Here, the fabrication of dye-sensitized solar cells has been performed utilizing CoS2 and MoS2 coated CoS2 nanocomposite materials as the counter electrode, which are synthesized via a hydrothermal route involving low-cost precursor materials. The experimental results obtained from XRD, XPS, EDX, SEM, TEM, and Raman etc. have confirmed the successful formation of CoS2 and MoS2 coated CoS2 nanocomposites. The electrochemical characterization of these materials is performed, which suggests that the electrocatalytic activity towards the liquid iodine electrolyte of these materials is as good as that of the conventional Pt counter electrodes. So, dye-sensitized solar cell devices are fabricated by interpolating a (cis-bis(isothiocyanato)bis(2,2′-bipyridyl-4,4′-dicarboxylato)ruthenium(ii)) dye-loaded TiO2 photoanode and CoS2, MoS2 coated CoS2 and Pt counter electrodes using iodine/iodide as a liquid electrolyte. The devices fabricated with CoS2 counter electrodes have shown an open circuit voltage of 790 mV, a short circuit current of 11.9 mA cm-2, a fill factor of 0.54, and a power conversion efficiency of 6%. On the other hand, the device based on a Pt counter electrode has shown an open circuit voltage of 773 mV, a short circuit current of 13.4 mA cm-2, a fill factor of 0.54, and a power conversion efficiency of 6.6%. In addition, MoS2 coated with a CoS2 counter electrode has shown the best performance with an open circuit voltage of 763 mV, a short circuit current of 20.1 mA cm-2, a fill factor of 0.42, and a power conversion efficiency of 7.6%
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
