Critical realism, symptomatology and the pedagogy of crisis
No full textThe concluding chapter reviews our arguments in Part One in the light of the other contributions to this volume. The general significance of these contributions was explored in Chapter 1 and, rather than repeat that exercise, we focus here on specific lessons. Likewise, we will not return to the important question posed by Jane Roitman regarding whether it is scientifically and practically appropriate to treat the modern period in general as crisis prone and/or to assume that specific events and processes can best be defined as (symptoms of) crisis to the neglect of alternative ways of interpreting them. For we are not interested in highlighting crisis as a description or self-description of modern times as if this captures the Zeitgeist (spirit of the times) nor do we consider crisis can be the taken-for-granted form of Zeitdiagnostik, an approach that privileges crisis as an explanandum and/or explanans for historical and contemporary analyses of the modern period. Similarly, we do not consider the conditions of possibility of a general theory of crisis. For, while accepting that there are real crisis tendencies and actual crises, we are not interested in developing a general theory of crises or identifying the features of crisis in general. Indeed, there is no crisis in general or general crisis: only particular crises in and/or of particular sets of social relations and the totality of crises in a given conjuncture.2 Thus, any serious approach to crises must define the specific mix of crisis tendencies that create the abstract conditions of possibility for a given type of crisis and the specific features that define the specificity of a particular crisis, whether considered as an event and/or as a process. This is illustrated by the diversity of the case studies in this volume

Host races in Chaetostomella cylindrica (Diptera: Tephritidae): genetic and behavioural evidence
No full textThe highly oligophagous tephritid Chaetostomella cylindrica infests the flower heads of six genera and ten species of thistles in Lebanon. It predominantly utilizes two hosts occurring in sympatry, Notobasis syriaca and Onopordum illyricum. Previous work showed that adult flies emerging from N. syriaca fit more closely the description of the species, particularly with respect to the colour and pattern on the mesonotum; furthermore, significant differences were observed between the aculeus shape and length. This study investigates the biology of the immatures and compares adults from the two host races behaviourally and genetically. Larvae of both races fed in a similar way, with each larva destroying 310 achenes; however, the oviposition behaviour of females differed. Females of the Onopordum-associated flies laid an average of three eggs per head, and deposited the eggs glued to each others in a cluster, while females of the Notobasis-associated flies deposited their eggs unattached, usually with one egg per head. Subtle differences were also observed in the post-mating behaviour of adult males. DNA sequencing of an amplified fragment of the mitochondrial NADH-dehydrogenase subunit 1 gene revealed 44 single nucleotide polymorphisms in 622 base pairs. A PCR-RFLP method was developed to distinguish the two host-associated populations. Together with previously published morphometric studies, our data show that C. cylindrica consists of distinct host races, which seem to be reproductively isolated as two separate genetic lineages were observed. © 2009 Cambridge University Press.BASOV VM, 2000, ENTOMOLOGICAL REV, V80, P569; Bush G.L., 1975, P187; Cognato AI, 2006, J ECON ENTOMOL, V99, P1037; DIEHL SR, 1984, ANNU REV ENTOMOL, V29, P471, DOI 10.1146-annurev.en.29.010184.002351; Dres M, 2002, PHILOS T R SOC B, V357, P471, DOI 10.1098-rstb.2002.1059; EDGECOMBE WS, 1970, WEEDS LEBANON; ENGELKE DR, 1990, ANAL BIOCHEM, V191, P396, DOI 10.1016-0003-2697(90)90238-5; FOOTE RH, 1987, MONOGRAPH BIOSYSTEMA, V28, P817; Freidberg A., 1989, FAUNA PALAESTINA INS; GOEDEN RD, 1985, P ENTOMOL SOC WASH, V87, P564; Hebert PDN, 2003, P ROY SOC B-BIOL SCI, V270, P313, DOI 10.1098-rspb.2002.2218; KIMURA M, 1974, P NATL ACAD SCI USA, V71, P2848, DOI 10.1073-pnas.71.7.2848; Knio KM, 2007, J NAT HIST, V41, P1697, DOI 10.1080-00222930701494486; Knio KM, 2002, J NAT HIST, V36, P617, DOI 10.1080-00222930010023448; KORNEEV V A, 1986, Entomological Review (English Translation of Entomologicheskoye Obozreniye), V65, P35; Post G.E., 1932, FLORA SYRIA PALESTIN, V2; Robineau-Desvoidy AJB, 1830, MEMOIRES PRESENTES D, V2, P1; SHARP PM, 1989, J MOL EVOL, V28, P398, DOI 10.1007-BF02603075; Smith PT, 2002, MOL PHYLOGENET EVOL, V25, P372, DOI 10.1016-S1055-7903(02)00261-0; STECK GJ, 1984, ANN ENTOMOL SOC AM, V77, P669; Thompson FC, 1998, FRUIT FLY EXPERT IDE; WHITE IM, 1989, P CEC IOBC INT S FRU, P557; White IM, 1992, FRUIT FLIES EC SIGNI; WHITE IM, 1988, TEPHRITID FLIES DIPT; WOLSTENHOLME DR, 1985, GENETICS, V109, P725; ZWOLFER H, 1971, ANNU REV ENTOMOL, V16, P15622
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
Terellia fuscicornis (Diptera: Tephritidae): Biological and morphological adaptation on artichoke and milk thistle
No full textThe biology, morphology, and genetics of Terellia fuscicornis on cultivated artichoke and its new recorded host, Silybum marianum, are examined. Morphometrically, the two host-associated populations were distinct. Except for egg length, all immature stages of the artichoke-associated population were larger. Principal component analysis, based on head and wing measurements, showed that the adults from both populations clustered into two groups, with the adults reared from artichoke being larger. The ovipositor was significantly longer and blunter in the artichoke-associated females, reflecting the larger flower heads exploited. Male terminalia measurements showed significant differences between the two populations. Several differences in courtship behaviour were detected between the two populations. Although the two populations show allochronic isolation, sequencing of two mitochondrial genes, ND1 and COI, and one nuclear gene, 18S, revealed no genetic differences between the two populations. © 2009 Taylor and Francis.Abrahamson WG, 2001, AM ZOOL, V41, P928, DOI 10.1668-0003-1569(2001)041[0928:GFIAGA]2.0.CO;2; BUSH GL, 1969, EVOLUTION, V23, P237, DOI 10.2307-2406788; Bush Guy L., 1992, Psyche (Cambridge), V99, P335, DOI 10.1155-1992-67676; Bush G.L., 1975, P187; CRAIG TP, 1993, EVOLUTION, V47, P1696, DOI 10.2307-2410214; Diegisser T, 2006, MOL ECOL, V15, P681, DOI 10.1111-j.1365-294X.2006.02792.x; DIEHL SR, 1984, ANNU REV ENTOMOL, V29, P471, DOI 10.1146-annurev.en.29.010184.002351; Dres M, 2002, PHILOS T R SOC B, V357, P471, DOI 10.1098-rstb.2002.1059; ENGELKE DR, 1990, ANAL BIOCHEM, V191, P396, DOI 10.1016-0003-2697(90)90238-5; Freidberg A., 1989, FAUNA PALAESTINA INS; GOEDEN RD, 1985, P ENTOMOL SOC WASH, V87, P564; Goto SG, 2001, MOL PHYLOGENET EVOL, V18, P404, DOI 10.1006-mpev.2000.0893; HAN HY, 1994, BIOCHEM SYST ECOL, V22, P447, DOI 10.1016-0305-1978(94)90040-X; HARRIS P, 1968, CAN ENTOMOL, V100, P295; Knio KM, 2002, J NAT HIST, V36, P617, DOI 10.1080-00222930010023448; Morrow J, 2000, EVOLUTION, V54, P899; NEUENSCHWANDER P, 1983, Israel Journal of Entomology, V17, P81; Phillips V.

Development and Calibration of Reaction Models for Multilayered Nanocomposites
No full textThis dissertation focuses on the development and calibration of reaction models for multilayered nanocomposites. The nanocomposites comprise sputter deposited alternating layers of distinct metallic elements. Specifically, we focus on the equimolar Ni-Al and Zr-Al multilayered systems. Computational models are developed to capture the transient reaction phenomena as well as understand the dependence of reaction properties on the microstructure, composition and geometry of the multilayers. Together with the available experimental data, simulations are used to calibrate the models and enhance the accuracy of their predictions.Recent modeling efforts for the Ni-Al system have investigated the nature of self-propagating reactions in the multilayers. Model fidelity was enhanced by incorporating melting effects due to aluminum [Besnoin et al. (2002)]. Salloum and Knio formulated a reduced model to mitigate computational costs associated with multi-dimensional reaction simulations [Salloum and Knio (2010a)]. However, exist- ing formulations relied on a single Arrhenius correlation for diffusivity, estimated for the self-propagating reactions, and cannot be used to quantify mixing rates at lower temperatures within reasonable accuracy [Fritz (2011)]. We thus develop a thermal model for a multilayer stack comprising a reactive Ni-Al bilayer (nanocalorimeter) and exploit temperature evolution measurements to calibrate the diffusion parameters associated with solid state mixing (720 K - 860 K) in the bilayer. The equimolar Zr-Al multilayered system when reacted aerobically is shown to exhibit slow aerobic oxidation of zirconium (in the intermetallic), sustained for about 2-10 seconds after completion of the formation reaction. In a collaborative effort, we aim to exploit the sustained heat release for bio-agent defeat application. A simplified computational model is developed to capture the extended reaction regime characterized by oxidation of Zr-Al multilayers. Simulations provide insight into the growth phenomenon for the zirconia layer during the oxidation process. It is observed that the growth of zirconia is predominantly governed by surface-reaction. However, once the layer thickens, the growth is controlled by the diffusion of oxygen in zirconia.A computational model is developed for formation reactions in Zr-Al multilayers. We estimate Arrhenius diffusivity correlations for a low temperature mixing regime characterized by homogeneous ignition in the multilayers, and a high temperature mixing regime characterized by self-propagating reactions in the multilayers. Experimental measurements for temperature and reaction velocity are used for this purpose. Diffusivity estimates for the two regimes are first inferred using regression analysis and full posterior distributions are then estimated for the diffusion parameters using Bayesian statistical approaches. A tight bound on posteriors is observed in the ignition regime whereas estimates for the self-propagating regime exhibit large levels of uncertainty. We further discuss a framework for optimal design of experiments to assess and optimize the utility of a set of experimental measurements for application to reaction models.</p
Larvicidal activity of essential oils extracted from commonly used herbs in Lebanon against the seaside mosquito, Ochlerotatus caspius
No full textThis study investigates the potential of essential oils from commonly used medical and culinary herbs in Lebanon as an environmentally safe measure to control the seaside mosquito, Ochlerotatus caspius. The composition of essential oils extracted from parsley seeds and leaves, alpine thyme inflorescences, anis seeds, and coriander fruits were analyzed by GC-MS, and the major components of these oils were found to be thymol, sabinene, carvacrol, anethole, and linalool, respectively. Mosquito larvicidal assays were conducted to evaluate the LC50 and LC90 after 24 and 48 h of the essential oils and their major constituents. All of the tested oils proved to have strong larvicidal activity (LC50: 15-156 ppm) against Oc. caspius fourth instars, with the most potent oil being thyme inflorescence extract, followed by parsley seed oil, aniseed oil, and then coriander fruit oil. Toxicity of each oil major constituent was also estimated and compared to a reported larvicidal compound, eugenol. © 2007 Elsevier Ltd.

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
Expanding “Communities and Collections” in the K-State Research Exchange (K-REx) to benefit the K-State Community and Beyond
No full textKansas State University has used its institutional repository, the K-State Research Exchange (K-REx), to store and share its first year experience program, K-State First, and notably its common reading program, K-State First Book. We have done so with the aim that the accessibility and preservation of these documents ensures program stability, promotes engagement with first year programming, and provides the ability to foster growth,educational opportunities, and community building outside of K-State. Moving away from research concentrated repositories and taking a more holistic approach to scholarship, especially when realizing the pedagogical significance of collaborative campus programming, institutions can showcase, discover, preserve, and grow programs that shape campus communities and engagement.
This session will provide an overview of K-REx and spotlight the digital archive of the university’s first year experience program and common reading program, K-State First Book. We will discuss the benefits and challenges to expanding the purview of your repositories. We talkthrough the types of materials we decide to host in our repository and why we share what we do. We will also provide recommendations on new ways to evaluate what belongs in institutional repositories and how this diversity can benefit your program, your institution, the community, and others
