Nonmarine Ostracoda as proxies in (geo-)archaeology: a review
Abstract Ostracods as bioindicators are extremely useful for reconstructing palaeoenvironment and palaeoclimate and can also indicate the provenance of sediments and materials, for example, in studies on ancient commercial networks. Ostracods are small crustaceans that live in almost all aquatic habitats, both natural and man-made. Due to their calcitic carapace, they have high fossilization potential, and their use in geoarchaeology has been steadily increasing during the last decades. Their small size needs mean that only small volumes of sediment samples are needed, and species-specific ecological tolerances and preferences allow detailed palaeoenvironmental reconstructions. Typical methods of their application are palaeoecological analyses of associations based on ecological information and taphonomy, morphometric variability and stable isotope and chemistry analyses of their shells. The present paper aims to present an overview of applications of non-marine ostracods in (geo-)archaeological research, recommending sampling and analytical techniques for addressing archaeological research questions on palaeoclimate, habitat and landscape changes, water availability and quality, land use and other anthropogenic impacts, the provenance of materials and commercial networks to promote the application of Ostracoda in geoarchaeology/environmental archaeology.1 Introduction 2 Applications 2.1 short history of ostracodâbased palaeoenvironmental reconstructions 2.2 Palaeoclimate and palaeoenvironmental studies on continental archaeological sites 2.2.1 General palaeoenvironment/landscape reconstructions 2.2.2 Salinity 2.2.3 Temperature 2.2.4 Radiocarbon dating 2.3 Landscape changes by human activity 2.4 Water use and water works 2.5 Provenance studies 3 Methods for sampling and lab analyses 4 Conclusion
Nanostructure and crystallography of aberrant columnar vaterite in Corbicula fluminea (Mollusca)
Both the crystallographic and nanostructural organisation of aberrant columnar vaterite occurring in \ud
C. fluminea were characterised in detail for the first time using electron microscopic and x-ray \ud
powder diffraction techniques. At the millimetre scale, only a confinement of the otherwise \ud
randomly oriented c-axis to the growth surface is observed. Domains of one hundred or more \ud
individual vaterite columns with common c-axis orientation exist within this disordered material. \ud
Each column behaves as a single crystal on the scale of EBSD measurements, but is internally \ud
composed of smaller (0.3 â 1.3 ÎŒm in dimension) irregularly shaped and slightly misaligned \ud
crystalline units. These are in turn partitioned by porous boundaries into rounded nanodomains, up \ud
to 600 nm in size. The geometry of the nanodomains and their respective boundaries might suggest \ud
formation by the accretion of vesicles. In addition to crystallographic textures, this observation \ud
indicates formation under significant biological control with wider implications for possible causes \ud

AFTER FURTHER REVIEW: AN UPDATE ON MODELING AND DESIGN STRATEGIES FOR AGRICULTURAL DOSE-RESPONSE EXPERIMENTS
Research investigating dose-response relationships is common in agricultural science. This paper is an expansion on previous work by Guo, et al. (2006) motivated by plant nutrition research in horticulture. Plant response to level of nutrient applied is typically sigmoidal, i.e. no response at very low levels, observable response at mid-levels, point-of-diminishing returns and plateau at high levels. Plant scientists need accurate estimates of these response relationships for many reasons, including determining the lower threshold below which plants show deficiency symptoms and the point of diminishing returns, above which excessive doses are economically and environmentally costly. Guo et al. presented models and designs that address these requirements and a simulation study to assess and compare the small-sample behavior of these models and designs. This paper expands on that simulation study. In addition, a simulation study based procedure for exploring designs for experimental scenarios fitting this description is presented. This simulation study approach utilizes simulation based fit statistics in conjunction with various lack-of-fit plots to produce a design robust to multiple candidate models
A modified delphi involving laboratory faculty to define essential skills for pharmacy graduates
Objective. To define essential skills for Doctor of Pharmacy (PharmD) graduates that are needed in the four most common sectors of pharmacy practice as determined by expert faculty who instruct within pharmacy skills laboratories. Methods. A three-round Delphi method was used to establish consensus. In the first round, participants were asked what skills were needed by students at entry to practice in community, health-system, ambulatory care, and managed care pharmacy settings. In rounds two and three, participants were asked to rate each skill with a level of importance using a 10-point Likert scale (1=not important to 10=very important). Results. In round one, participants produced a collective list of 289 essential skills. These skill state-ments were sent to participants in rounds two and three to assign a level of importance. After the third round, participants reached consensus using a mean level of importance for a final list of 69 community pharmacy skills, 47 health-system, 60 ambulatory care, and 15 managed care skills. These skills were then mapped to entrustable professional activities domains for schools and colleges pharmacy to use as a resource when assessing core competency development in the curriculum. Conclusion. The Delphi technique was used successfully with expert pharmacy skills laboratory faculty to identify laboratory-focused essential skills that recent PharmD graduates should have prior to entering community, health-system, ambulatory care, or managed care pharmacy practice. These essential skills can be used to guide curriculum development, develop milestone markers, and help ensure students are practice ready
Nonradiative Electronic Deexcitation Time Scales in Metal Clusters
The life-times due to Auger-electron emission for a hole on a deep electronic
shell of neutral and charged sodium clusters are studied for different sizes.
We consider spherical clusters and calculate the Auger-transition probabilities
using the energy levels and wave functions calculated in the
Local-Density-Approximation (LDA).
We obtain that Auger emission processes are energetically not allowed for
neutral and positively charged sodium clusters. In general, the Auger
probabilities in small Na clusters are remarkably different from the
atomic ones and exhibit a rich size dependence.
The Auger decay times of most of the cluster sizes studied are orders of
magnitude larger than in atoms and might be comparable with typical
fragmentation times.Comment: 11 pages, 4 figures. Accepted for publication in Phys. Rev.

Types of boredom: an experience sampling approach
The present study investigated different types of boredom as proposed in a four-categorical conceptual model by Goetz and Frenzel (2006; doi:10.1026/0049-8637.38.4.149). In this model, four types of boredom are differentiated based on degrees of valence and arousal: indifferent, calibrating, searching, and reactant boredom. In two studies (Study 1: university students, N = 63, mean age 24.08 years, 66 % female; Study 2: high school students, grade 11, N = 80, mean age 17.05 years, 58 % female), real-time data were obtained via the experience-sampling method (personal digital assistants, randomized signals). Boredom experiences (N = 1,103/1,432 in Studies 1/2) were analyzed with respect to the dimensions of valence and arousal using multilevel latent profile analyses. Supporting the internal validity of the proposed boredom types, our results are in line with the assumed four types of boredom but suggest an additional, fifth type, referred to as âapathetic boredom.â The present findings further support the external validity of the five boredom types in showing differential relations between the boredom types and other affective states as well as frequency of situational occurrence (achievement contexts vs. non-achievement contexts). Methodological implications as well as directions for future research are discussed
Cyclic degradation of titanium-tantalum high-temperature shape memory alloys - The role of dislocation activity and chemical decomposition
Titanium-tantalum shape memory alloys (SMAs) are promising candidates for actuator applications at elevated temperatures. They may even succeed in substituting ternary nickel-titanium high temperature SMAs, which are either extremely expensive or difficult to form. However, titanium-tantalum alloys show rapid functional and structural degradation under cyclic thermo-mechanical loading. The current work reveals that degradation is not only governed by the evolution of the Ï-phase. Dislocation processes and chemical decomposition of the matrix at grain boundaries also play a major role.DFG/NI1327/3-1DFG/MA1175/34-1DFG/EG101/22-1DFG/FR2675/3-
Gauge Theories with Cayley-Klein and Gauge Groups
Gauge theories with the orthogonal Cayley-Klein gauge groups and
are regarded. For nilpotent values of the contraction
parameters these groups are isomorphic to the non-semisimple Euclid,
Newton, Galilei groups and corresponding matter spaces are fiber spaces with
degenerate metrics. It is shown that the contracted gauge field theories
describe the same set of fields and particle mass as gauge
theories, if Lagrangians in the base and in the fibers all are taken into
account. Such theories based on non-semisimple contracted group provide more
simple field interactions as compared with the initial ones.Comment: 14 pages, 5 figure
