A Tribute to Professor Alexopoulos
No full textThis issue of the Proceedings began to take form on June 17, 1973, at the University of Massachusetts when many of the former students of Professor Alexopoulos gathered to present him and Mrs. Alexopoulos with a day of appreciation. The reading of scientific papers written by his students, the banquet that evening, and the preparation of this issue of the Proceedings which includes those papers was an honor for all of us because it provided an opportunity to express our appreciation to our warmly admired teacher. That the Board of the Iowa Academy of Science, especially the Editorial Board of the Proceedings, saw fit to join the celebration testifies to what we all know: the respect and admiration for Professor Alexopoulos\u27 contributions to mycology and education are recognized by many others besides his former students
Business school techspectations Technology in the daily lives and educational experiences of business students
No full textBusiness School Techspectations is the second in a series of reports based on research by the DCU Leadership, Innovation and Knowledge Research Centre (LInK) at DCU Business School. With its roots in an Irish business school, it is no surprise that LInK’s mission is to strengthen the competitiveness, productivity, innovation and entrepreneurial capacity of the Irish economy. Ireland’s next generation transformation will be enabled by information and communication technologies (ICT) and digital participation by members of Irish society. As a university research centre we have an important role to play in supporting education, industry and government to accelerate this transformation
Management Matters
No full textNew indications of managerial innovations are created and then used to show that changes in organizational technologies are an important source of economic growth. Specifically, the analysis demonstrates that, first, in response to a positive managerial technology shock, output, productivity and hours significantly increase in the short run, second, these types of innovations are as important as non-managerial ones in explaining movements in these variables at business cycle frequencies, and, third, product and process innovations promote the development of new managerial techniques.Business Cycles; Productivity; Management techniques; Technical Change

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
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Extracellular matrix associated with human luteininzing granulosa cells
No full textHuman granulosa cells (GC), prepared from follicular aspirates using a non-enzymic method, were maintained on chamber slides in a defined medium without additional attachment factors. In this system, GC clustered to a limited extend and attached only loosely to the substream necessitating medium replacement through repeated partial changes to avoid cell loss. Cell size and progesterone production increased consistently with continuing luteinization. These processes were associated with maintenance and deposition of the endogenous extracellular matrix components heparan sulphate proteoglycan and laminin (α2, β1, γ1 subunits) as shown by both Western blotting and immunohistochemistry. Collagen IV seemed to be present between freshly prepared GC and was maintained in culture. The addition of either epidermal growth factor (EGF) or basic fibroblast growth factor (bFGF) into the culture medium did not reveal any marked effect on deposition of laminin components during culture. Release of cell clusters, particularly in the absence of gonadotrophin, was noted during the later stages of culture, constituting the so-called 'lift off' phenomenon. This has been correlated with an increasing concentration of matrix metalloproteinases (MMP-2) in the culture medium during the culture period. To conclude, luteinization and maintenance of the GC-derived layer of the corpus luteum is likely to involve deposition and conservation of pericellular extracellular matrix components, actively synthesized by the GC themselves and controlled by the presence of gonadotrophin.</p
Illness and inhumanity in Stalin's Gulag /
No full textA new and chilling study of lethal human exploitation in the Soviet forced labor camps, one of the pillars of Stalinist terror In a shocking new study of life and death in Stalin's Gulag, historian Golfo Alexopoulos suggests that Soviet forced labor camps were driven by brutal exploitation and often administered as death camps. The first study to examine the Gulag penal system through the lens of health, medicine, and human exploitation, this extraordinary work draws from previously inaccessible archives to offer a chilling new view of one of the pillars of Stalinist terror.Includes bibliographical references and index.Introduction: Exploiting "human raw material" -- Food: "Whoever does not work, shall not eat" -- Prisoners: "The contingent" -- Health: "Physical labor capability" -- Illness and mortality: "Lost labor days" -- Invalids: "Inferior workforce" -- Releases: "Unloading the ballast" -- Power: "We are not doctors but delousers" -- Selection: "The more (and less) valuable human element" -- Exploitation: "Labor utilization" -- Epilogue: Deaths and deceptions.A new and chilling study of lethal human exploitation in the Soviet forced labor camps, one of the pillars of Stalinist terror In a shocking new study of life and death in Stalin's Gulag, historian Golfo Alexopoulos suggests that Soviet forced labor camps were driven by brutal exploitation and often administered as death camps.
