Unternehmenszusammenschlüsse im Zeichen der Globalisierung

In der jüngsten Vergangenheit haben sich transnationale Zusammenschlüsse von Unternehmen insbesondere im Finanzdienstleistungs- und Industriebereich gehäuft. Welche Motive liegen diesen Fusionen zugrunde? Stellen die Zusammenschlüsse eine Gefahr für den Wettbewerb dar? Welche wettbewerbspolitischen Optionen gibt es? --

Identification and quantification of native arbuscular mycorrhizae fungi of citrus in the State of Rio Grande do Sul, Brazil

O objetivo deste trabalho foi identificar e quantificar os esporos de FMA presentes em viveiros e pomares de citros no Rio Grande do Sul. Foram coletadas amostras de solo e de raízes de dez viveiros e doze pomares de oito municípios produtores de citros, nas quais avaliaram-se conteúdo nutricional, número de esporos por 100 g de solo seco e colonização das radicelas, e determinaram-se as espécies autóctones. As espécies, em ordem decrescente de ocorrência, foram: Glomus macrocarpum > Scutellospora heterogama > Acaulospora scrobiculata = Acaulospora birreticulata > Glomus invermaium = Glomus occultum = Entrophospora colombiana > Glomus claroideum = Glomus constrictum > Scutellospora persica.The objective of this work was to identify and quantify AMF spores present in citrus nurseries and orchards in Rio Grande do Sul, Brazil. Soil and root samples were collected at ten nurseries and twelve citrus orchards. Mineral composition of the soil samples was determined as well as the number of spores in 100 g of dry soil, root colonization and native species taxonomic identification. AMF species, in decreasing order of occurrence were: Glomus macrocarpum > Scutellospora heterogama > Acaulospora scrobiculata = Acaulospora birreticulata > Glomus invermaium = Glomus occultum = Entrophospora colombiana > Glomus claroideum = Glomus constrictum > Scutellospora persica

Multidimensional signals and analytic flexibility: Estimating degrees of freedom in human speech analyses

Recent empirical studies have highlighted the large degree of analytic flexibility in data analysis which can lead to substantially different conclusions based on the same data set. Thus, researchers have expressed their concerns that these researcher degrees of freedom might facilitate bias and can lead to claims that do not stand the test of time. Even greater flexibility is to be expected in fields in which the primary data lend themselves to a variety of possible operationalizations. The multidimensional, temporally extended nature of speech constitutes an ideal testing ground for assessing the variability in analytic approaches, which derives not only from aspects of statistical modeling, but also from decisions regarding the quantification of the measured behavior. In the present study, we gave the same speech production data set to 46 teams of researchers and asked them to answer the same research question, resulting insubstantial variability in reported effect sizes and their interpretation. Using Bayesian meta-analytic tools, we further find little to no evidence that the observed variability can be explained by analysts’ prior beliefs, expertise or the perceived quality of their analyses. In light of this idiosyncratic variability, we recommend that researchers more transparently share details of their analysis, strengthen the link between theoretical construct and quantitative system and calibrate their (un)certainty in their conclusions

Feasibility of CT scan studies with triple split bolus intravenous contrast medium technique and reduced radiation dose for potential kidney donors

Objective: To show that it is possible to reduce the radiation dose in the examination of potential kidney donors by splitting the contrast injection followed by a single scanning, enabling evaluation of vascular structures, renal parenchyma and collecting system/ureters, using computed tomography protocols with reduced mAs. Methods: Twenty-six potential donors were evaluated based on the following criteria: image quality, radiation dose reduction, and complications associated with the exam. The criteria were scored by two examiners, and the differences were resolved by consensus. Rresults: For each item assessed, 85 to 90% of studies were scored as very good or excellent with regards to image quality. There was excellent interobserver agreement, and there were no significant differences between the exams with low radiation dose compared to those with the conventional dose. No exam-related complications were observed. Cconclusions: The CT scan study with triple-split bolus technique and low dose is effective for reducing the dose of radiation to potential kidney donors

Acute and chronic mesenteric ischemia: MDCT findings

Mesenteric ischemia is caused by a reduction in mesenteric blood flow. It can be divided into acute and chronic, based upon the rapidity and the degree to which the blood flow is compromised. The authors retrospectively reviewed 22 cases of mesenteric ischemia, diagnosed by multidetector computed tomography (MDCT) in our service, and confirmed by surgery or clinical follow-up. The frequency of the diagnostic findings of chronic and acute mesenteric ischemia was evaluated. The improvement of three-dimensional (3D) MDCT allows accurate assessment of mesenteric vessels. Therefore, it demonstrates changes in ischemic bowel segments helpful in determining the primary cause of the disease, and can identify the complications in patients with acute and chronic mesenteric ischemia
