Soil resource supply influences faunal size-specific distributions in natural food webs

The large range of body-mass values of soil organisms provides a tool to assess the ecological organization of soil communities. The goal of this paper is to identify graphical and quantitative indicators of soil community composition and ecosystem functioning, and to illustrate their application to real soil food webs. The relationships between log-transformed mass and abundance of soil organisms in 20 Dutch meadows and heathlands were investigated. Using principles of allometry, maximal use can be made of ecological theory to build and explain food webs. The aggregate contribution of small invertebrates such as nematodes to the entire community is high under low soil phosphorus content and causes shifts in the mass-abundance relationships and in the trophic structures. We show for the first time that the average of the trophic link lengths is a reliable predictor for assessing soil fertility responses. Ordered trophic link pairs suggest a self-organizing structure of food webs according to resource availability and can predict environmental shifts in ecologically meaningful ways.

Unlocking synergies between business units: internal value creation at Royal Vopak.

This paper examines the process of creating and exploiting synergies between business units of a multi-unit corporation and the creation of internal value by combining and exploiting knowledge. It offers a framework to create and manage such synergies and undertakes an empirical test through in-depth study across three business units of Royal Vopak, a Dutch-based global multi-unit corporation. Finally, it offers lessons for corporate managers trying to create and manage cross-unit synergies.

Europe's New Border Tax.

Instead of abolishing internal border controls in 1993, the European Union (EU) replaced them with VAT and statistical requirements that appear to be just as onerous. For Dutch businesses, the compliance costs of the new requirements are, on average, 5 per cent of the value of their intra-EU trade. The figure is probably higher for other EU Member States. Obviously, the costs constitute a (differentiated) border tax that impedes intra-EU trade. The article analyses the determinants of the compliance costs, as well as their effect on intra-EU trade intensity. The article submits that the differential compliance costs violate the non-discrimination provisions of the EC Treaty. Suggestions are made to reduce them.

Fatty acids and CHD

During the last century much evidence has accumulated to suggest that from a public health perspective the type of fat is more important than the amount of fat. Saturated and trans-fatty acids increase and both n-6 and n-3 PUFA decrease the risk of CHD. Most of the knowledge about the effects of dietary fatty acids on CHD risk is based on observational studies and controlled dietary experiments with intermediate end points (e.g. blood lipoprotein fractions). Information from high-quality randomised controlled trials on fatty acids and CHD is lacking. The Netherlands Institute for Public Health has calculated the potential health gain that can be achieved if the fatty acid composition of the current Dutch diet is replaced by the recommended fatty acid composition. The recommendations of The Netherlands Health Council are: saturated fatty acids

Weather Prognostics in Anglo-Saxon England

Prognostics concerning the day of the week on which kalendae ianuariae and Christmas Day fall, commonly known as the Revelatio Esdrae , purport to be a set of prophecies by the Biblical Esdras. They make predictions about the weather and other natural phenomena for the year to come, and they then extend their predictions to the field of human affairs. A remarkable number of copies of the Revelatio appear in English manuscripts from the tenth to the twelfth centuries. Some of these versions have been attributed to Bede and Abbo of Fleury as part of their computus works.

Both R. M. Liuzza and L. S. Chardonnens point out the frequent occurrence of the Revelatio in religious and scientific manuscripts and therefore reject the label of folklore, stressing instead the probable monastic origin of this prognostication. This study will provide the first complete collation and analysis of the surviving exemplars, to give as full an idea as possible of their circumstances of composition, their transmission, and their relationship to one another. It will consider how the Revelatio Esdrae was copied and used in Anglo-Saxon England, the audience to which it was addressed, and whether any conclusion can be drawn from its appearance in particular manuscripts, alongside certain other texts.

The regular occurrence of the Revelatio along with computistical material supports the case for its monastic origin and learned nature. Such a text would have been a helpful handbook to be used by monks and priests, and was among the standard holdings of continental and Anglo-Saxon monasteries and scriptoria, giving further proof of the monks’ intellectual eclecticism and their knowledge of the kinds of continental literature from which this text derives.

The Sacred and the Obscure: Greek in the Carolingian Reception of Martianus Capella

Carolingian scholars paid considerable attention to the Greek found in Martianus Capella’s De nuptiis Philologiae et Mercurii, a late antique Latin work full of obscurities in language and imagery. This article, focusing on glosses on De nuptiis from the oldest gloss tradition, demonstrates that a range of material was available to ninth-century scholars to elucidate Martianus’s Greek and that Greek seems, at times, to have served as a means to obscure. I argue that their interest in obscurity reflects a widespread epistemology and strategy of concealment, hence their intellectual investment in Martianus. For ninth-century readers, then, the Greek in the glossed Martianus manuscripts, however decorative it may have been, also operated at the core of medieval hermeneutics.

Identification of dyes on ancient Chinese paper samples using the subtracted shifted Raman spectroscopy method

The Stein Collection in the British Library contains the Diamond Sutra, the world's oldest, dated, printed document. The paper of the Diamond Sutra and other documents from the Stein collection is believed to be dyed yellow by a natural extract, called huangbo, from the bark of Phellodendron amurense, which contains three major yellow chromophores: berberine, palmatine, and jatrorrhizine, Conservation of these documents requires definite information on the chemical composition of the dyes but no suitable, completely noninvasive analytical method is known. Here we report resonance Raman studies of a series of prate dyes, of plant materials and extracts, and of dyed ancient and modern paper samples. Resonance Raman spectroscopy is used to enhance the spectra of the dyes over the signals from the paper matrixes in which they are held. The samples an give resonance Raman spectra which are dominated by intense fluorescence, but by using SSRS (subtracted shifted Raman spectroscopy) we have obtained reliable spectra of the pure dyes, native bark from the Phellodendron amurense, modern paper dyed with huangbo extracted from this bark, and ancient paper samples. For both ancient paper samples whose pigment bands were detected, the relative intensities of the bands due to berberine and palmatine suggest that the ancient paper is richer in berberine than its modern counterpart, This is the first nondestructive in situ method for detection of these pigments in manuscripts, and as such has considerable potential benefit for the treatment of irreplaceable documents that are believed to be dyed with huangbo but documents on which conservation work cannot proceed without definite identification of the chemical compounds that they contain.

Epistolarum Familiarium Liber Unus in The Complete Works of John Milton: Volume XI (672pp.)

This edition of Milton’s Epistolarum Familiarium Liber Unus and of his Uncollected Letters, will appear as 672 pp. of The Complete Works of John Milton Volume XI, eds. Gordon Campbell and Edward Jones (Oxford University Press, forthcoming 2016). A diplomatic Latin text and a new facing English translation are complemented by a detailed Introduction and commentary that situate Milton’s Latin letters in relation to the classical, pedagogical and essentially humanist contexts at the heart of their composition. Now the art of epistolography advocated and exemplified by Cicero and Quintilian and embraced by Renaissance pedagogical manuals is read through a humanist filter whereby, via the precedent (and very title) of Epistolae Familiares, the Miltonic Liber is shown to engage with a neo-Latin re-invention of the classical epistola that had come to birth in quattrocento Italy in the letters of Petrarch and his contemporaries. At the same time the Epistolae are seen as offering fresh insight into Milton’s views on education, philology, his relations with Italian literati, his blindness, the poetic dimension of his Latin prose, and especially his verbal ingenuity as the ‘words’ of Latin ‘Letters’ become a self-conscious showcasing of etymological punning on the ‘letters’ of Latin ‘words’. The edition also announces several new discoveries, most notably its uncovering and collation of a manuscript of Henry Oldenburg’s transcription (in his Liber Epistolaris held in Royal Society, London) of Milton’s Ep. Fam. 25 (to Richard Jones). Oldenburg’s transcription (from the original sent to his pupil Jones) is an important find, given the loss of all but two of the manuscripts of Milton’s original Latin letters included in the 1674 volume. The edition also presents new evidence in regard to Milton’s relationships with the Italian philologist Benedetto Buonmattei, the Greek humanist Leonard Philaras, the radical pastor Jean Labadie (and the French church of London), and the elusive Peter Heimbach.

Development of an egg hatch assay for the diagnosis of triclabendazole resistance in Fasciola hepatica: proof of concept.

The aim of this study was to develop an Egg Hatch Assay (EHA) test for the detection of triclabendazole (TCBZ) resistance in Fasciola hepatica. A number of fluke isolates were used, of differing sensitivity to TCBZ. Eggs were exposed to solutions of triclabendazole sulphoxide (TCBZ.SO) for 14 days, then triggered to hatch. Egg development was divided into 6 distinct and easily identifiable stages: dead, empty, unembryonated, cell division, eye spot and hatched. The number of eggs reaching those stages was recorded. Initially, the discriminating dose (1% hatch) was determined for the Cullompton isolate, used as TCBZ-susceptible (TCBZ-S) standard. Once this concentration had been resolved, the response of different isolates to this concentration was examined. The hatch rate of the Fairhurst isolate was not significantly different from that of the Cullompton isolate, confirming its TCBZ-S status. The Patagonia isolate has not been exposed to TCBZ in the field and should be TCBZ-S: the results of the EHA supported this. The egg hatch response of the Oberon and Dutch isolates differed significantly from that of the Cullompton isolate; the former isolates are regarded as TCBZ-resistant (TCBZ-R) and the results confirmed this. Another isolate, the Leon isolate, was originally described as being TCBZ-R, but has since been shown to be TCBZ-S. There was no difference in its response to TCBZ.SO in the EHA from the Cullompton (and Fairhurst and Patagonia) isolate(s), further indicating its TCBZ-S status. The impact of TCBZ.SO treatment on the component stages of egg development was determined and revealed differences between the isolates. In conclusion, the results of the study have shown that it is possible to discriminate between TCBZ-S and TCBZ-R isolates of F. hepatica on the basis of the response of their eggs to an EHA and the test could be used to evaluate the TCBZ sensitivity of unknown field isolates

Do multinationals really prefer to enter culturally distant countries through greenfields rather than through acquisitions? The role of parent experience and subsidiary autonomy.

Prior research has argued that multinational enterprises (MNEs) prefer to enter culturally distant countries through greenfields rather than through acquisitions, since acquisitions in such countries are costlier to manage. This argument contains two hidden assumptions: (1) the additional costs of acquisitions in culturally distant countries are the same for all MNEs; and (2) such acquisitions have no benefits over their greenfield counterparts. In this paper we relax these two assumptions by arguing that an MNE's preference for greenfields in culturally distant countries depends on its international and host-country experience, and on the level of autonomy it plans to grant the focal subsidiary. Analyzing 171 wholly owned greenfield investments and full acquisitions made by Dutch MNEs in 35 countries, we find that these MNEs prefer to enter culturally distant countries through greenfields, but that this preference is lower when they have little international experience, or plan to grant the focal subsidiary considerable autonomy in marketing.

Do Foreign Greenfields Outperform Foreign Acquisitions or Vice Versa? An Institutional Perspective.

Prior studies of the comparative performance of greenfields and acquisitions have advanced competing arguments, with some arguing that greenfields should outperform acquisitions because acquisitions are costlier to integrate, and others that acquisitions should outperform greenfields because greenfields suffer from a liability of newness. Moreover, while the costs of integration and the liability of newness are at their greatest during a subsidiary's first years, prior studies have tested their competing arguments on samples containing older subsidiaries. We extend these prior studies by (1) developing an institutional theory-based framework that simultaneously considers the costs of integration and the liability of newness, (2) recognizing that both types of costs vary with the level of subsidiary integration, and (3) focusing on the stage of their life during which subsidiaries predominantly incur these costs. To measure subsidiary performance, we ask managers of Dutch multinationals how their ex ante performance expectations compare to the subsidiary's ex post performance during its first two years. Analysing a sample of 191 foreign subsidiaries and controlling for entry mode self-selection and other factors, we find that acquisitions outperform greenfields at low and intermediate levels of subsidiary integration, but that greenfields outperform acquisitions at higher integration levels.

Bracketing: practical considerations in Husserlian phenomenological research

Nursing research leans heavily towards naturalism, with phenomenology commonly adopted. The three main schools of phenomenology used are Husserl's descriptive approach, Heidegger's interpretive hermeneutic approach and the Dutch Utrecht School of phenomenology which combines characteristics of both. Husserl's approach--the description of ordinary human experiences as perceived by each individual--involves four main steps: bracketing, intuiting, analysing and describing. Many phenomenological nurse researchers consciously decide to adopt a Heideggerian approach because of the perceived difficulties in achieving bracketing. This paper examines the concept of bracketing (epoché) and outlines some of the practical considerations when attempting to achieve it.

Accounts of debates in the House of Commons, March– April 1731, supplementary to the diary of the first earl of Egmont

John Perceval (1685–1748), 1st Viscount Perceval and (from 1733) 1st Earl of Egmont, was an assiduous recorder of his own life and times. His diaries, published by the Historical Manuscripts Commission from manuscripts in the British Library, are the best source for parliamentary debates at Westminster in the 1730s. For the years 1730-1733, when Perceval sat in the Commons (as an Irish peer) they are remarkably full. His practice seems to have been to prepare two versions (presumably on the basis of notes taken in the House), the first attributing speeches to individuals, and the second, entered up in the diary, which listed speakers and summarized all arguments on each side. His letterbooks for 1731 contain accounts of five debates that embody his first editing process, with speeches attributed to individuals. They were sent to an Irish correspondent, Marmaduke Coghill, and largely omitted from the diary because Perceval had already transcribed them elsewhere. They are new to historians and cast light on two main issues: the unsuccessful attempts by Perceval and the ‘Irish lobby’ to persuade the British parliament to settle the Irish woollen trade, a question bedevilling Anglo-Irish relations in this period; and an attempt by the opposition to stir up anger against perceived Spanish aggression against Gibraltar. One of the most interesting features is the insight afforded into the Commons performances of Sir Robert Walpole: his management of debates, his own style of speaking, and his sharp exchanges with opponents like William Pulteney.
