Interview With P.C. Hodgell
No full textP.C. Hodgell, author of God Stalk and Dark of the Moon, was one of the many authors who attended Mythcon XIX in Berkeley last summer. She was good enough to meet with the Mythic Circle writers\u27 roundtable and share some of her experiences with us. The following is transcribed from a low-quality tape; when it was possible to recognize a speaker’s voice I have identified them - others are noted as ct. Hope you enjoy it
Nonequilibrium and classical dissipation scalings in DNS of homogeneous isotropic decaying turbulence
No full textWe present data from direct numerical simulations of homogeneous isotropic decaying turbulence showing both the non-equilibrium and the classical dissipation scalings reported in wind-tunnel experiments of both regular and fractal grid-generated turbulence, i.e. Cε ∼ (Re0/Reλ)n with n of order unity and Cε ∼ constant, respectively (Re0 and Reλ are global and local Reynolds numbers). These two dissipation behaviours lead to different power-law decay exponents in both regimes also in accord with the experiments. Finally, we show that in both regimes the maximum non-linear energy cascade flux, Π, reasonably satisfies the classical expectation that Π ∼ K3/2/l
Decreased preference and reproduction, and increased mortality of Frankliniella occidentalis on thrips-resistant pepper plants
No full textThe effect of thrips resistance in pepper (Capsicum annuum L.) - previously shown to result in impeded thrips population development (Maris PC, Joosten NN, Goldbach RW & Peters D (2003a) Restricted spread of Tomato spotted wilt virus in thrips-resistant pepper. Phytopathology 93: 1223-1227. Maris PC, Joosten NN, Goldbach RW & Peters D (2003b) Spread of Tomato spotted wilt virus and population development of Frankliniella occidentalis in pepper resistant to thrips. Proceedings of the Section Experimental and Applied Entomology Netherlands Entomological Society (NEV) Amsterdam 14: 95-101.) - on thrips'[Frankliniella occidentalis Pergande (Thysanoptera: Thripidae)] reproduction, mortality, host preference, and behaviour was investigated. Reproduction, studied by oviposition and larval survival, was negatively affected by the thrips-resistant (TR) phenotype, whereas the offspring's developmental rate did not differ on TR and the thrips-susceptible (TS) phenotype. While thrips' behaviour was hardly affected by thrips resistance, a significant preference for TS plants over the TR plants was found in different tests. When released on either a TR or a TS plant, thrips dispersed at significantly higher rates from the TR plants, demonstrating that not only an impeded reproduction, but also a reduced residence time adds to the reported lower thrips numbers on TR plants
Reinforcing glass with glass: Application of transport reinforcement in structural glass beams
No full textDue to the increasing demand of transparency in buildings, it is no longer unusual to apply transparent elements into the bearing structure. Glass is a strong but very brittle material, which means safety is rather problematic should it break. Safety is an issue that has to be improved before glass can be considered suitable for structural elements. Earlier studies have shown that reinforcing glass beams will provide reasonable residual load-bearing capacity, which could provide this safety. Glass fibre is suitable as reinforcement material when the transparency is regarded as important. In February 2009 at the Faculty of Architecture at Delft University of Technology, P.C. Louter designed and tested a laminated glass beam with embedded glass fibre rods. The bonding interlayer consisted of SentryGlas foil, developed by DuPont and often applied for lamination in hurricane-resistant windows. The results were promising and the concept showed high potential for further research. The study of this thesis project is focussed on improving the concept of embedding reinforcement in laminated glass beams.Design and ConstructionCivil Engineering and Geoscience
Evaluation of thrips resistance in pepper to control Tomato spotted wilt virus infection
No full textThe objective of this study was to analyse the effect of thrips ( F. occidentalis ) resistance in pepper ( Capsicum ) on the spread of Tomato spotted wilt virus (TSWV). Results demonstrate that the rate of primary TSWV-infection is effectively limited in a thrips-resistant (TR) pepper crop compared to a thrips-susceptible (TS) crop, and that this is based on a decreased preference of thrips for TR plants. Secondary TSWV-infections were effectively restricted in the TR pepper crop and this is based on a greatly reduced thrips population built-up.<o:p></o:p></span>The effect of thrips resistance on the spread of TSWV was also analysed in a virus-resistant genotype. TSWV-resistant plants respond with a hypersensitive reaction after infection with TSWV, resulting in necrotic local lesions on leaves and fruits. Under the same infection pressure, fewer local lesions were found in the thrips-resistant accession PI 152225 than in the thrips-susceptible PI 159236 accession, indicating a synergistic effect of thrips- and virus resistance.<o:p></o:p></span>Studies presented in the last part of the thesis show mutual benefits for F. occidentalis and TSWV from the attraction to virus-infected plants. Attraction resulted in more offspring on these plants and thereby enhancing the chance for virus transmission. Besides, thrips developed significantly faster on TSWV-infected plants than on non-infected plants. It was demonstrated that volatiles released from TSWV-infected plants may be involved in the attraction of thrips to TSWV-infected plants
Foreign Direct Investment. The key determinants of foreign direct investment in Poland. Case company: ArgusPack P.C.
No full textThe aim of this thesis was to provide a better understanding of the determinants of foreign direct invest-ment (referred to hereafter as “FDI”). The company ArgusPack P.C. is a flexible packaging manufacturer located in Greece which decided to engage using FDI in Poland. Thus, the factors that favors FDI into the selected region had to be determined.
This thesis was a qualitative research, an empirical non-numerical data research. For primary data a series of interviews was conducted by the author and for secondary data peer-reviewed articles and literatures that fully-describe the determinants of FDI were utilized. There are numerous theories that define the FDI, such as Vernon’s product life cycle (Vernon, 1966), Buckley and Casson’s internalization theory (P. Buckley, 1976) and Dunning’s eclectic paradigm (Dunning J. , 2001). In this project, the Dunning’s eclectic paradigm theory was selected and applied, aiming to provide a better understanding of the factors that motivates a company or an organization to become involved using FDI. Through a research study the primary data were collected and through excessive academic research the secondary data were collected as well. In conclu-sion, an analysis of the primary data in combination with the secondary data was done mainly focusing on the participants’ point of view and the way it aligns with the theoretical aspect given by this thesis. In the end a conclusion and recommendation were formed based on all data mentioned and the personal belief of the author.
Finally, since the key determinants have been identified and examined. Foreign direct investment seems to be an adequate business strategy for ArgusPack P.C. in Polan
The Quest for Citations: Drivers of Article Impact
No full textWhy do some articles become building blocks for future scholars, while many others remain unnoticed? We aim to answer this question by contrasting, synthesizing and simultaneously testing three scientometric perspectives – universalism, social constructivism and presentation – on the influence of article and author characteristics on article citations. To do so, we study all articles published in a sample of five major journals in marketing from 1990 to 2002 that are central to the discipline. We count the number of citations each of these articles has received and regress this count on an extensive set of characteristics of the article (i.e. article quality, article domain, title length, the use of attention grabbers and expositional clarity), and the author (i.e. author visibility and author personal promotion). We find that the number of citations an article in the marketing discipline receives, depends upon “what one says†(quality and domain), on “who says it†(author visibility and personal promotion) and not so much on “how one says it†(title length, the use of attention grabbers, and expositional clarity). Our insights contribute to the marketing literature and are relevant to scientific stakeholders, such as the management of scientific journals and individual academic scholars, as they strive to maximize citations. They are also relevant to marketing practitioners. They inform practitioners on characteristics of the academic journals in marketing and their relevance to decisions they face. On the other hand, they also raise challenges towards making our journals accessible and relevant to marketing practitioners: (1) authors visible to academics are not necessarily visible to practitioners; (2) the readability of an article may hurt academic credibility and impact, while it may be instrumental in influencing practitioners; (3) it remains questionable whether articles that academics assess to be of high quality are also managerially relevant.Impact;Citation Analysis;Referencing;Scientometrics;Cite
