Data analysis tools for safe drinking water production
No full textProviding safe and high quality drinking water is essential for a high quality of life. However, the water resources in Europe are threatened by various sources of
contamination. This has led to the development of concepts and technologies to create a basis for provision of safe and high quality drinking water, which had thus resulted in the formation of the Artificial Recharge Demonstration project (ARTDEMO). The
overall aim of this thesis in relation to the ARTDEMO project was to develop a realtime
automated water monitoring system, capable of using data from various complementary sources to determine the amounts of inorganic and organic pollutants.
The application of multivariate calibration to differential pulse anodic stripping
voltammograms and fluorescence spectra (emission and excitation-emission matrix) is
presented. The quantitative determination of cadmium, lead and copper acquired on
carbon-ink screen-printed electrodes, arsenic and mercury acquired on gold-ink
screen-printed electrodes, in addition to the quantitative determination of anthracene,
phenanthrene and naphthalene have been realised. The statistically inspired
modification of partial least squares (SIMPLS) algorithm has been shown to be the
better modelling tool, in terms of the root mean square error of prediction (RMSEP),
in conjunction with application of data pre-treatment techniques involving rangescaling,
filtering and weighting of variables. The % recoveries of cadmium, lead and
copper in a certified reference material by graphite furnace atomic absorption
spectrometry (GF-AAS) and multivariate calibration are in good agreement.
The development of a prototype application on a personal digital assistant (PDA)
device is described. At-line analysis at potential contamination sites in which an
instant response is required is thus possible. This provides quantitative screening of target metal ions. The application imports the acquired voltammograms, standardises
them against the laboratory-acquired voltammograms (using piecewise direct
standardisation), and predicts the concentrations of the target metal ions using
previously trained SIMPLS models.
This work represents significant progress in the development of analytical techniques
for water quality determination, in line with the ARTDEMO project's aim of
maintaining a high quality of drinking water

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
Experimental bone marrow transplantation
No full textThis study formed part of a theses entitled “The Influence of extra-corporeal irradiation on Lympho- and Haemopoiesis” submitted by Dr. Maurice N. Cauchi to the University of London for the Ph.D. degree, 1967. Studies on bone marrow transplantation assume fundamental importance and studies that might shed any light on the problem of growth, division, and differentiation of bone marrow are likely to be of interest. The material and methods used in an experimental bone marrow transplantation is described. The results following this experiment are outlined, indicating the main findings, of which that iron uptake was linearly related to the dose of bone marrow cells injected and that anemia had no significant effect on the repopulating ability of bone marrow stem cells. However, it is not to be concluded that anemia has no effect on the bone marrow cellularity. Of interest is the discussion, wherein it emerged that although the induction of polycythaemia by hypertransfusion leads to a reduction of the erythropoieic elements in the marrow (Alpen et al., 1962 ), the cells from such bone marrow did not behave significantly different from normal bone marrow, indicating that there are as many differentiated cells in the erythropoieic, as in the normal bone marrow.peer-reviewe
The need for increasing the retrieval of organs : doctors’ attitudes towards opting-out
No full textSome countries have introduced the opting-out system of organ donation as a way of increasing the number of available organs for transplants. Public opinion is divided on this issue and so are medical recommendations. While some claim that opting-out is the only way forward to increase the harvesting of organs and transplants, others claim that the decision whether or not to donate the organs of a dead relative should be a voluntary decision taken by the next of kin. In this paper, five doctors who are directly involved in organ donation or transplantation in Malta were interviewed on the issue of the harvesting of organs. The interviews were recorded, transcribed and analysed. The interviewees concur that since the rate of refusals is still low in Malta, the opt-in system which is currently in practice should be retained.peer-reviewe
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

No full textCan archives of audiovisual TV interviews be used to make authors more visible to students, and thereby reduce the learning gap between native and non-native language speakers in college classes? We examined students in a college course who learned about one scholar's ideas through watching an audiovisual TV interview (i.e., visible author format) and about another scholar's ideas through reading a formal text description (i.e., invisible author format). For the invisible author, native language speakers scored significantly higher than the non-native language speakers on a corresponding exam question (i.e., a cognitive measure), generated more words on the exam question (i.e., a motivational measure), and mentioned the author's name more often in answering the exam question (i.e., an affective measure). For the visible author, the groups did not differ on any of these measures. These findings provide evidence for the idea that making the author visible through audiovisual TV interviews can eliminate the learning gap between native and non-native language speakers. 3 Universities around the world serve students who are non-native speakers of th
