Planktivores and plankton dynamics : effects of fish biomass and planktivore type

Les auteurs ont quantifié les incidences de la biomasse et du type de planctophage dans le cadre d'une étude expérimentale en mésocosmes. Cette étude était conçue en fonction d'un plan factoriel d'expérience combinant cinq niveaux de biomasse de poisson (de O, à 75 g/m3) avec deux types de planctophage, soit l'alose à gésier (#Dorosoma cepedianum), un filtreur, et le crapet arlequin (#Lepomis macrochirus), un chasseur visuel. Une augmentation de la biomasse de poisson était accompagnée d'une baisse du nombre de cladocères, de cyclopoïdes et de chironomides et de la teneur en phosphore particulaire ...; inversement l'abondance de rotifères, de flagellés unicellulaires, d'algues vertes coloniales et unicellulaires, de diatomées pennées, la productivité primaire, la turbidité et les teneurs en chlorophylle a, en phosphore total ... ont augmenté ... Bien que la chaîne des cascades trophiques de l'alose à gésier et celle du crapet soleil soient différentes, la biomasse de poisson jouait un rôle plus important que le type de planctophage comme régulateur des communautés planctoniques et de la qualité de l'eau.

Systematisierung und Analyse von Crowd-Sourcing-Anbietern und Crowd-Work-Projekten

Mit dem Begriff Crowdsourcing bezeichnete Jeff Howe 2006 den damals neuen Trend, bislang intern erledigte Aufgaben über das Internet an eine unbegrenzte Menge potenziell Mitwirkender (die "crowd") auszulagern ("outsourcing"). Dazu nutzen Unternehmen heute einen wachsenden Markt an externen Crowdsourcing-Plattformen. Die vorliegende Studie bietet einen systematischen Überblick und identifiziert dabei fünf verschiedene Grundformen: (1) Microtask-Plattformen, (2) Marktplatz-Plattformen, (3) Design-Plattformen, (4) Testing-Plattformen und (5) Innovationsplattformen. Diese Grundformen unterscheiden sich in den Steuerungs- und Kontrollmechanismen sowie den Anreizstrukturen und Vergütungsformen, mit denen sie die Arbeit in der Crowd organisieren

Technology adoption in the BIM implementation for lean architectural practice

Justification for Research: the construction companies are facing barriers and challenges in BIM adoption as there is no clear guidance or best practice studies from which they can learn and build up their capacity for BIM use in order to increase productivity, efficiency, quality, and to attain competitive advantages in the global market and to achieve the targets in environmental sustainability. Purpose: this paper aims to explain a comprehensive and systemic evaluation and assessment of the relevant BIM technologies as part of the BIM adoption and implementation to demonstrate how efficiency gains have been achieved towards a lean architectural practice. Design/Methodology/Approach: The research is undertaken through a KTP (Knowledge transfer Partnership) project between the University of Salford and the John McCall Architects based in Liverpool, which is an SME (Small Medium Enterprise). The overall aim of KTP is to develop Lean Design Practice through the BIM adoption and implementation. The overall BIM implementation approach uses a socio-technical view in which it does not only consider the implementation of technology but also considers the socio-cultural environment that provides the context for its implementation. The technology adoption methodology within the BIM implementation approach is the action research oriented qualitative and quantitative research for discovery, comparison, and experimentation as the KTP project with JMA provides an environment for “learning by doing” Findings: research has proved that BIM technology adoption should be undertaken with a bottom-up approach rather than top-down approach for successful change management and dealing with the resistance to change. As a result of the BIM technology adoption, efficiency gains are achieved through the piloting projects and the design process is improved through the elimination of wastes and value generation. Originality/Value: successful BIM adoption needs an implementation strategy. However, at operational level, it is imperative that professional guidelines are required as part of the implementation strategy. This paper introduces a systematic approach for BIM technology adoption based on a case study implementation and it demonstrates a guideline at operational level for other SME companies of architectural practices

Major Histocompatibility Complex I and II Expression and Lymphocytic Subtypes in Muscle of Horses with Immune-Mediated Myositis.

BackgroundMajor histocompatibility complex (MHC) I and II expression is not normally detected on sarcolemma, but is detected with lymphocytic infiltrates in immune-mediated myositis (IMM) of humans and dogs and in dysferlin-deficient muscular dystrophy.Hypothesis/objectivesTo determine if sarcolemmal MHC is expressed in active IMM in horses, if MHC expression is associated with lymphocytic subtype, and if dysferlin is expressed in IMM.AnimalsTwenty-one IMM horses of Quarter Horse-related breeds, 3 healthy and 6 disease controls (3 pasture myopathy, 3 amylase-resistant polysaccharide storage myopathy [PSSM]).MethodsImmunohistochemical staining for MHC I, II, and CD4+, CD8+, CD20+ lymphocytes was performed on archived muscle of IMM and control horses. Scores were given for MHC I, II, and lymphocytic subtypes. Immunofluorescent staining for dysferlin, dystrophin, and a-sarcoglycan was performed.ResultsSarcolemmal MHC I and II expression was detected in 17/21 and 15/21 of IMM horses, respectively, and in specific fibers of PSSM horses, but not healthy or pasture myopathy controls. The CD4+, CD8+, and CD20+ cells were present in 20/21 IMM muscles with CD4+ predominance in 10/21 and CD8+ predominance in 6/21 of IMM horses. Dysferlin, dystrophin, and a-sarcoglycan staining were similar in IMM and control muscles.Conclusions and clinical importanceDeficiencies of dysferlin, dystrophin, and a-sarcoglycan are not associated with IMM. Sarcolemmal MHC I and II expression in a proportion of myofibers of IMM horses in conjunction with lymphocytic infiltration supports an immune-mediated etiology for IMM. The MHC expression also occured in specific myofibers in PSSM horses in the absence of lymphocytic infiltrates

Crowd Worker in Deutschland: Eine empirische Studie zum Arbeitsumfeld auf externen Crowdsourcing-Plattformen

Crowdsourcing, von den einen als innovative Form der Arbeitsorganisation gefeiert, von den anderen als neue Form prekärer Beschäftigung verteufelt, ist inzwischen eines der meist diskutierten Themen in der Debatte um die Digitalisierung der Arbeitswelt. Auf der Basis einer Befragung von 434 Crowd Workern bietet diese Studie einen differenzierten Blick auf die Situation von Crowd Workern in Deutschland: Welche Personengruppen bieten ihre Arbeit auf den unterschiedlichen Crowdsourcing-Plattformen an? Wie viel Zeit verwenden sie für die Arbeit in der Crowd? Was verdienen sie? Welche Bedeutung hat die Arbeit in der Crowd für ihren Lebensunterhalt? Wie sichern sie sich sozial ab? Wie zufrieden sind sie? Was wünschen sie sich für ihre berufliche Zukunft
