A multi-platform package for the analysis of intra- and interspecific trait evolution

Gaboriau, Théo ; Mendes, Fábio K. ; Joly, Simon ; Silvestro, Daniele ; Salamin, Nicolas

In: Methods in Ecology and Evolution, 2020, p. -

Evolutionary forces affect the distribution of phenotypes both within and among species. Yet, at the macro‐evolutionary scale, the evolution of intraspecific variance is rarely considered. Here, we present an r and a BEAST 2 implementation that extends the JIVE (Joint inter‐ and Intraspecific Variance Evolution) model aimed at the analysis of continuous trait evolution at both inter‐...

Students' Problem Behaviors as Sources of Teacher Stress in Special Needs Schools for Individuals With Intellectual Disabilities

Amstad, Meta ; Müller, Christoph Michael

In: Frontiers in Education, 2020, vol. 4, p. 1-11

Students with intellectual disabilities in special needs schools often exhibit high levels of problem behaviors. Besides of the challenges for the concerned individuals, peers, and their caregivers, problem behaviors can also be a source of stress for teachers. However, less is known on which exact behaviors are perceived as how stressful in special needs schools for students with...

Feeding biomechanics suggests progressive correlation of skull architecture and neck evolution in turtles

Ferreira, Gabriel S. ; Lautenschlager, Stephan ; Evers, Serjoscha W. ; Pfaff, Cathrin ; Kriwet, Jürgen ; Raselli, Irena ; Werneburg, Ingmar

In: Scientific Reports, 2020, vol. 10, p. 5505

The origin of turtles is one of the most long-lasting debates in evolutionary research. During their evolution, a series of modifications changed their relatively kinetic and anapsid skull into an elongated akinetic structure with a unique pulley system redirecting jaw adductor musculature. These modifications were thought to be strongly correlated to functional adaptations, especially to bite...

When the Watchdog Neither Barks nor Bites : communication as a power resource in media policy and regulation

Ali, Christopher ; Puppis, Manuel

In: Communication theory, 2018, vol. 28, no. 3, p. 270-291

Communication in policymaking and regulation has been of interest to political scientists for the last 15 years. Lamentably, the conceptualization and analysis of communication in media policymaking and regulation has yet to garner much attention from media policy scholars. Drawing on theories of power and new institutionalism, we address this paucity by introducing a theoretical and...

Composition and technology of 18th century high magnesia faïences from Fulda

Maggetti, Marino ; Serneels, Vincent ; Stasch, Georg

In: Journal of Archaeological Science: Reports, 2015, vol. 2, p. 40–50

In 1996, archaeological excavations close to the ancient Fulda faïence manufacture site unearthed a rich deposit of faïence wastes (biscuits, faïences, technical ceramics). The manufacture was founded in 1741 by Prince Abbot Amand von Buseck and closed down in 1761. This first archaeometric study of a German faïence manufacture included 31 samples produced between 1742 and 1760. Analytical...

White earthenware from Lorraine (1755 –c. 1820): provenance and technique

Maggetti, Marino ; Rosen, J. ; Serneels, Vincent

In: Archaeometry, 2011, vol. 53, no. 4, p. 765–790

Fragments of 25 examples of ‘white earthenware’ from Lorraine were subjected to porosity analysis, X-ray fluorescence analysis, X-ray diffraction analysis and backscattered-electron image analysis—coupled with energy-dispersive spectrometry to determine the porosity, bulk, major, minor and trace element compositions, and the composition and the proportion of their constituent...
