Core Journal Lists: Classic Tool, New Relevance
No full textReviews the historical context of core journal lists, current uses in collection assessment, and existing methodologies for creating lists. Outlines two next generation core list projects developing new methodologies and integrating novel information/data sources to improve precision: a national-level core psychology list and the other a local institutional core list for the interdisciplinary field of urban studies and planning. The paper is based on the authors’ panel presentation at the 2009 ACRL National Conference (Seattle, Washington) titled “Core Journal Lists Re-viewed and Re-imagined.”This is an electronic version of an article published in Robin A.

Mindscapes: Laura Riding's poetry and poetics /
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão.Esta tese propõe uma leitura revisionista da poesia contemporânea através do exame do caso de um dos mais esquecidos escritores norte-americanos do século XX: Laura (Riding) Jackson (1901-1991). O objetivo é demonstrar que Riding não apenas possuía uma poética definida e singular, mas que ela permanece uma das instâncias mais extremas e paradoxais do modernismo anglo-americano, a ponto de Riding abandonar a escrita da poesia em 1938. Recorrendo a conceitos de "formação do cânone" bem como às noções de "discurso" e "função do autor", em Foucault, investigo a construção do cânone da poesia moderna anglo-americana, recuperando o contexto e as circunstâncias da ocultação de Riding. Enquanto cubro os "discursos" poéticos em circulação na primeira metade do século XX-o "imagismo" de Pound, a "dissociação da sensibilidade", "impersonalidade" e "tradição" de Eliot, a "unidade orgância" e "ambigüidade" da Nova Crítica-ofereço um panorama crítico de modernismos alternativos sendo articulados à época. Minha intenção é demonstrar que os poemas de Riding são expressões vigorosas de um escritor para quem "a mente pensando se torna a força ativa do poema", para usar a apta formulação de Charles Bernstein. Entre minhas descobertas sobre as várias e complexas razões que levaram à não-canonização de Riding estão a hegemonia da Nova Crítica, o exílio voluntário de Riding da cena literária (onde são feitas ou desfeitas as reputações), sua recusa em ser antologiada, bem como em ser explicada em termos críticos que não os dela. Todos esses fatores, mais a "dificuldade" de sua poesia, contribuíram para fazer de Riding "a maior poeta esquecida da poesia norte-americana", como escreveu Kenneth Rexroth. Ajudado pelos insights de dois importantes críticos de poesia norte-americana, Charles Bernstein e Marjorie Perloff, defendo que a "poesia da mente" de Riding-onde o que está em jogo é que o que pensamos ser a nossa realidade-representa uma mudança radical no paradigma da poética modernista: de uma poesia centrada na imagem para uma poesia centrada na linguagem. Focalizando a experiência consciente e o tempo duracional do pensamento presente em seus poemas, concluo que as "pensagens" de Riding têm o objetivo preciso de constatar um fato universal: enquanto seres humanos e pensantes, estamos numa condição permanente chamada linguagem
Heritage tourism: a case study of the Laura Ingalls Wilder Heritage Site at Pepin, Wisconsin
No full textPlan BMany things must be taken into consideration when developing a heritage tourism site. It can be a wonderful opportunity for the community involved to benefit economically and historically. Heritage tourism can keep alive the heritage and traditions of the communities past. When it is discovered that a heritage site exists, the first step is to consult with the community. A site will not succeed without the acceptance and assistance from the community involved. Once the interest is known, the development process can proceed. After determining that there is a heritage tourism site possibility in their area, a commumity must do research to determine the feasibility of the site, what will make it a success, and how to obtain that success. This study will examine a community with a heritage tourism site that has been successful in developing and maintaining it's site. By conducting this study, other communities seeking information for developing their site will have an example and tool to work with. The site chosen for this study is the Laura Ingalls Wilder site in Pepin, Wisconsin. The town is rich with it's heritage associated with Laura Ingalls Wilder. The development and success for this town will be documented through this study. Laura Ingails Wilder is a perfect choice for examining heritage tourism. The author of many American Pioneer books, she has become famous all over the world. In turn all places that she or her family members lived are or are becoming heritage tourism sites. There are older ones that have been in progress for some years, such as the one in Pepin, and there are ones that are being discovered through the popularity of new books written about Laura's family. These communities would benefi greatly from the information this study will produce. Without the bene-fit of this knowledge communities who are unaccustomed to tourism or the way the other Laura Ingalls Wilder sites operate, may make terrible errors in development, tarnishing the site. This may also reflect badly on the other Laura Ingalls Wilder sites. It is important for new Wilder sites to examine all information and know exactly what they are doing when developing the site. If all the Laura Ingalls Wilder sites can benefit from each other's knowledge and experience it will greatly increase the market for all sites. The more detailed and expansive the sites are about their knowledge and sites to see, the more people are going to want to travel to as many sites as possible, learning all they can about the life of Laura Ingalls Wilder and her family. These sites not only attract Laura Ingalls Wilder fans but all people that are interested in the American Pioneer period of the United States history. This study will provide the knowledge for communities who are developing heritage tourism sites, especially those focusing on Laura Ingalls Wilder. This is a very important study for tourism and especially heritage tourism. When a heritage site is discovered communities run into the barrier of not having the experience and knowledge to develop the site properly. This study will analyze tourism in Pepin, Wisconsin to determine it's successfulness due to the fact that it is a Laura Ingalls Wilder heritage tourism site, and Wfit was developed in a way to provide tourists with a view of Laura Ingalls Wilder's past and the past of many Pioneer Americans. By studying this subject it will allow for many people to benefit. Tourist who are seeking the pleasure of the knowledge of the past, and communities who want to preserve their past and profit from tourism
Teasing apart fine- and coarse-scale effects of environmental heterogeneity on tree species richness in Europe
No full textThe environmental heterogeneity–biodiversity relationship is generally hypothesised to be positive, with greater heterogeneity leading to greater biodiversity. However, the generality of positive environmental heterogeneity–species richness relationships is often debated, with some studies finding non-significant or even negative relationships. Negative relationships have primarily been found at fine spatial scales. Both negative and positive relationships have a basis in ecological theory. Environmental heterogeneity at coarse scales opens up niche space to allow more species to coexist; whereas high local heterogeneity, for instance in topography, may lead to increased local extinction due to micro-fragmentation, or dominance of species suited to heterogeneous conditions. However, it is difficult to attribute how much of the variance is explained at different scales within the same modelling framework.Here, we use a new data-aggregation method which enables us to include both fine- and coarse-scale environmental heterogeneity within the same analysis. Using this method, we were able to tease apart the fine- and coarse-grain effects of topographic heterogeneity on European tree species richness. At the coarse scale (0.5 degrees), we found a positive effect of range in elevation on tree species richness. However, when measuring range in elevation using a fine-scale moving window of radius 500 m, we found a negative relationship with tree species richness. This supports existing research that has shown negative relationships between environmental heterogeneity and species richness at finer spatial grains. Because we were able to include a measure of both local and landscape-scale topographic heterogeneity in the same model, for the first time we could fully capture the effects of both scales on coarse-grain species richness while accounting for the effect of the other scale
Marketing management capabilities of SMEs: an empirical analysis in the EU
No full textSMEs, that represent the greater part of European food firms producing traditional food products (TFPs), meet difficulties in adapting their strategies to market changes, and in competing with big enterprises. Marketing management capabilities play a key role in good SMEs performance in the market. The purpose of this paper is to evaluate the marketing capabilities of SMEs that produce TFPs. The theoretical framework considers the Market Orientation approach and marketing management capabilities in terms of marketing research, marketing strategy, planning and implementation, control and evaluation. A self evaluation tool was developed by means of an interactive questionnaire, available on the web, aimed at assessing traditional food firms competitive position in the marketing area. The sample consists of 112 Italian firms. Descriptive analysis shows that the most problematic dimensions of the marketing management are planning and implementation and control and evaluation. Moreover, the firms’ size is not a relevant feature to determine the marketing capabilities, whereas quality voluntary certifications have a direct linkage with marketing capabilities, as the more a firm is certified the more t improves its marketing performance. Linear Regression model confirms these results.Marketing capabilities, SMEs, traditional food, linear regression, Agribusiness, Marketing,
The maternal immune system during pregnancy and its influence on fetal development
No full textThe maternal immune system plays a critical role in the establishment, maintenance, and completion of a healthy pregnancy. However, the specific mechanisms utilized to achieve these goals are not well understood. Various cells and molecules of the immune system are key players in the development and function of the placenta and the fetus. Effector cells of the immune system act to promote and yet limit placental development. The T helper 1 (Th1)/T helper 2 (Th2) immune shift during pregnancy is well established. A fine balance between proinflammatory and anti-inflammatory influences is required. We herein review the evidence regarding maternal tolerance of fetal tissues and the underlying cell-mediated immune and humoral (hormones and cytokines) mechanisms. We also note the many unanswered questions in our understanding of these mechanisms. In addition, we summarize the clinical manifestations of an altered maternal immune system during pregnancy related to susceptibility to common viral, bacterial, and parasitic infections, as well as to autoimmune diseases.Peer reviewe
Effects of Moritella viscosa antigens on pro-inflammatory gene expression in an Atlantic salmon (Salmo salar Linnaeus) cell line (SHK-1)
No full textMoritella viscosa is the causative agent of winter ulcer disease in salmonids reared in North-Atlantic countries. In this study the effects of selected M. viscosa antigens on cytotoxicity and pro-inflammatory gene expression in an Atlantic salmon (Salmo salar Linnaeus) macrophage-like cell line (SHK-1) were examined. SHK-1 cells were stimulated with live and heat-killed bacterial cells, extracellular products (ECP) and an extracellular vibriolysin, termed MvP1. Following incubation, cytotoxicity and expression levels of interleukin-1β (IL-1β) and interleukin-8 (IL-8) were examined at different time points. Both live M. viscosa cells and ECP were cytotoxic, but neither heat-killed cells, nor the MvP1 peptidase caused cell death. Expression levels of both IL-1β and IL-8 increased significantly after stimulation with live cells, but heat-killed cells only caused increased IL-8 expression. ECP did not affect IL-1β expression, but did stimulate IL-8 expression. The isolated MvP1 peptidase stimulated both IL-1β and IL-8 expression at the highest concentration tested. This study reveals a difference in the induction of pro-inflammatory gene expression in salmon SHK-1 cells between live and heat-killed M. viscosa cells, and also that an unknown secreted factor is the main stimulant of IL-β and IL-8 expression.ID: S1050464809000990; M3: Article; Accession Number: S1050464809000990; Author: Bryndis Bjornsdottir (a, b); Author: Mark D.

Remarks: Most of the specimens deposited in SAMA and ANIC were published under T. undecimmaculatus in Watts (2000) before. Description. A large, blackish and broadly-elongate species, widest in middle, with reddish markings on elytra and pronotum (Figs 1, 2). Measurements. TL: 4.6–4.7 mm (holotype 4.7 mm); TL–H: 4.1–4.2 mm (holotype 4.2 mm); MW: 2.4–2.5 mm (holotype 2.5 mm); TL/MW: 1.88–1.91. Colour. Head black. Pronotum sides, base and portions of middle dark red-brown; with two reddish spots basally. Elytron with six vague red patches dorsally and laterally. Ventral surface dark reddish-brown. Epipleuron, prosternum and legs mainly rufo-piceous; metatibia and -tarsus dark brown. Appendages rufo-piceous, apical segments of male protarsus almost black. Sculpture. Dorsal surface reticulate, strongly and densely rugose-punctate throughout, but punctures on dorsal surface shallow. Pronotum with a distinct raised ridge parallel to and a little distant from each side, area just inside ridge depressed, ridge and depression strongest anteriorly, weak posteriorly. Elytron weakly margined, strongly convex, rounded and slightly broadened behind middle. Prothoracic process narrow, strongly convex, roundly pointed at apex, little constricted between procoxae. Metacoxal lines raised, slightly to moderately diverging anteriorly. Male. Protarsus 3-segmented. Protarsomeres broadened and proximally expanded, those on mesotarsomeres little expanded. Single claw on protarsus (there is only one claw in males of Tiporus) weakly curved, slightly thickened and with a small tooth on underside near base. Male protibia with small tooth just beyond middle (Fig. 1). Tip of last abdominal ventrite weakly to strongly tuberculate in middle and with short carina. Metatibia normal, not expanded. Median lobe of aedeagus broad in centre but narrow at tip (Figs 5 a, b); right paramere as in Fig. 5 c. Female. Protarsus 5-segmented, robust somewhat expanded on inside, with two simple claws. Protibia on posterior side without tooth (Fig. 2). Tip of last abdominal ventrite flattened. Lateral extension of elytron near tip weak but visible. Etymology. Named after the Queensland State in Australia where all the type material has been collected. The species name is an adjective in the nominative singular. Distribution. North-eastern Queensland, Australia, from the Wenlock River in the north to Collinsville in the south (Fig. 11). Habitat. A lotic species. At Watsonville T. queenslandicus sp. n. was collected in deeper rest pools of a broad, shallow and sandy creek. The associated fauna comprised Copelatus irregularis W.J. Macleay, 1871, Laccophilus clarki Sharp, 1882, Necterosoma regulare Sharp, 1882, Sternopriscus hansardii (Clark, 1862), Hydroglyphus mastersii (W.J. Macleay, 1871), Hydroglyphus daemeli (Sharp, 1882) and Limbodessus rivulus (Larson, 1994). Near Herberton it was collected in a still flowing but temporary stream, forming pools together with Laccophilus walkeri Balfour-Browne, 1939 and the hydrophilid Berosus trishae Watts, 1987. Affinities. In habitus T. queenslandicus sp. n. is similar to T. giuliani (Fig. 3) and T. undecimmaculatus (Fig. 4). From the darker T. undecimmaculatus it can be separated by its well-developed dorsal colour pattern, the spine on the male protibia which is close to the centre (Fig. 8), not toward the apex (Fig. 10), and the broader central lobe of the aedeagus (Figs 7 a, b). From T. giuliani it can be distinguished by the form of the median lobe and parameres (Figs 6 a, b, c), and the almost black legs and tarsi. Furthermore, in T. giuliani the margin in lateral view of the elytron curves forward for a short distance immediately before it meets the edge of the pronotum, whereas it is straight or almost so in T. queenslandicus sp. n. Tiporus undecimmaculatus and T. giuliani are also distinctly smaller (TL of T. undecimmaculatus: 3.6–3.7 mm and T. giuliani: 4.0– 4.1 mm) than Tiporus queenslandicus sp. n. (TL: 4.6–4.7 mm). The new species is restricted to north-eastern Queensland whereas T. giuliani and T. undecimmaculatus are only known from the Northern Territory and north-western Australia (Fig. 11). Genetically, all Tiporus species are comparably strongly differentiated from each other based on mitochondrial cox1 gene divergences. This has been shown by Hendrich et al. (2010, fig. 2 D), where clustering specimens using uncorrected p-distances even at 10% threshold will retrieve the same clusters corresponding to morphologically delineated species. Accordingly, when we compared a cox1 sequence for Tiporus queenslandicus sp. n. available from Genbank (EU617001, from R. Leys and under the name T. undecimmaculatus) with one of our true T. undecimmaculatus (Genbank FR733053) we find divergence of about 14% which is very high for Coleoptera and strong indicator for presence of different species. Comparison with T. giuliani (FR733049) revealed the same magnitude of divergence.Published as part of Hendrich, Lars, Balke, Michael & Watts, Chris H.
