Detailed Presentation

Recent trends in archaeological research dictate the incorporation of various analytical methods for dating, chemical/mineralogical characterization, morphological description, etc. of various excavation findings and landscapes to support and corroborate the archaeologists' observations. Each method, when used individually, provides a different feedback, but once single studies are combined, the information produced can significantly contribute to the solution of the archaeological puzzle. Thus, numerous scientific data and metadata are produced creating large and complex scientific datasets. The use of common terminology and definitions to describe these data along with the establishment of a formal standardized structure that any cultural heritage information could be mapped to would assure the credibility and durability of such scientific datasets. The present work provides an overview of the types and formats of the scientific data and metadata produced in the archaeological research through the detailed presentation of the common practices used in pottery provenance studies.

AbstractWe critically engage two traditional views of scientific data and outline a novel philosophical view that we call the pragmatic-representational (PR) view of data. On the PR view, data are representations that are the product of a process of inquiry, and they should be evaluated in terms of their adequacy or fitness for particular purposes. Some important implications of the PR view for data assessment, related to misrepresentation, context-sensitivity, and complementary use, are highlighted. The PR view provides insight into the common but little-discussed practices of iteratively reusing and repurposing data, which result in many datasets’ having a phylogeny—an origin and complex evolutionary history—that is relevant to their evaluation and future use. We relate these insights to the open-data and data-rescue movements, and highlight several future avenues of research that build on the PR view of data.

Ate appearances deceiving? Do objects behave the way they do becauseGod wills it? Ate objects impetmanent and do they only exist becausethey ate continuously created by God? According to a1 Ghazlli, theanswers to all of these questions ate yes. Objects that appear to bepermanent are not. Those relationships commonly tefemed to as causalare a result of God’s habits rather than because one event inevitably leadsto another. God creates everything in the universe continuously; if Heceased to create it, it would no longer exist.These ideas seem oddly naive and unscientific to people living in thetwentieth century. They seem at odds with the common conception of thephysical world. Common sense says that the universe is made of tealobjects that persist in time. Furthermore, the behavior of these objects isreasonable, logical, and predictable. The belief that the univetse is understandablevia logic and reason harkens back to Newton’s mechanical viewof the universe and has provided one of the basic underpinnings ofscience for centuries. Although most people believe that the world is accutatelydescribed by this sort of mechanical model, the appropriatenessof such a model has been called into question by recent scientificadvances, and in particular, by quantum theory. This theory implies thatthe physical world is actually very different from what a mechanicalmodel would predit.Quantum theory seeks to explain the nature of physical entities andthe way that they interact. It atose in the early part of the twentieth centuryin response to new scientific data that could not be incorporated successfullyinto the ptevailing mechanical view of the universe. Due largely ...

Although most economists are skeptical of or puzzled by the Catholic concept of the common good, a rejection of the economic approach as inimical to the common good would be hasty and counterproductive. Economic analysis can enrich the common good tradition in four ways. First, economics embodies a deep respect for economic agency and for the effects of policy and institutions on individual agents. Second, economics offers a rich literature on the nature of unplanned order and how it might be shaped by policy. Third, economics offers insight into the public and private provision of various kinds of goods (private, public, common pool resources). Fourth, recent work on the development and logic of institutions and norms emphasizes sustainability rooted in the good of the individual.

Abstract Background Walking and running are the most common means of locomotion in human daily life. People have made advances in developing separate exoskeletons to reduce the metabolic rate of walking or running. However, the combined requirements of overcoming the fundamental biomechanical differences between the two gaits and minimizing the metabolic penalty of the exoskeleton mass make it challenging to develop an exoskeleton that can reduce the metabolic energy during both gaits. Here we show that the metabolic energy of both walking and running can be reduced by regulating the metabolic energy of hip flexion during the common energy consumption period of the two gaits using an unpowered hip exoskeleton. Methods We analyzed the metabolic rates, muscle activities and spatiotemporal parameters of 9 healthy subjects (mean ± s.t.d; 24.9 ± 3.7 years, 66.9 ± 8.7 kg, 1.76 ± 0.05 m) walking on a treadmill at a speed of 1.5 m s−1 and running at a speed of 2.5 m s−1 with different spring stiffnesses. After obtaining the optimal spring stiffness, we recruited the participants to walk and run with the assistance from a spring with optimal stiffness at different speeds to demonstrate the generality of the proposed approach. Results We found that the common optimal exoskeleton spring stiffness for walking and running was 83 Nm Rad−1, corresponding to 7.2% ± 1.2% (mean ± s.e.m, paired t-test p < 0.01) and 6.8% ± 1.0% (p < 0.01) metabolic reductions compared to walking and running without exoskeleton. The metabolic energy within the tested speed range can be reduced with the assistance except for low-speed walking (1.0 m s−1). Participants showed different changes in muscle activities with the assistance of the proposed exoskeleton. Conclusions This paper first demonstrates that the metabolic cost of walking and running can be reduced using an unpowered hip exoskeleton to regulate the metabolic energy of hip flexion. The design method based on analyzing the common energy consumption characteristics between gaits may inspire future exoskeletons that assist multiple gaits. The results of different changes in muscle activities provide new insight into human response to the same assistive principle for different gaits (walking and running).

Our results are the first insight into groundwater copepods of the Polish Lowland. The sampling was conducted in 28 wells in north-eastern Poland, and Copepoda were present in 16 wells. We have identified six Copepoda species and one Cladocera. We have classified four species as stygophiles—Eucyclops serrulatus, Diacyclops bisetosus, Diacyclops crassicaudis, and Cyclops furcifer. These species were frequently found in studied wells of different regions of north-eastern Poland, often in high numbers, and females with egg sacs were observed. We present a detailed morphological description of these species, together with molecular characteristics based on mitochondrial DNA markers (COI gene) for E. serrulatus, D. bisetosus, and D. crassicaudis, and 12S ribosomal RNA for C. furcifer. We also present the development of abnormal structures in one specimen of D. crassicaudis, where the upper part of furcal rami was fused to form a single plate.

Roll Out

This article offers insight into the role of the state in land financialisation through a reading of urban hegemony. This offers the basis for a conjunctural analysis of the politics of planning within a context in which authoritarian neoliberalism is ascendant across Europe. I explore this through the case of Antwerp as it underwent a hegemonic shift in which the nationalist neoliberal party the New Flemish Alliance (Nieuw-Vlaamse Alliantie; N-VA) ended 70 years of Socialist Party rule and deregulated the city’s technocratic planning system. However, this unbridling of the free market has led to the creation of high-margin investment products rather than suitable housing for the middle classes, raising concerns about the city’s gentrification strategy. The consequent, politicisation of the city’s planning system led to controversy over clientelism which threatened to undermine the N-VA’s wider hegemonic project. In response, the city has sought to roll out a more formalised system of negotiated developer obligations, so embedding transactional, market-oriented informal governance networks at the centre of the planning system. This article highlights how the literature on land financialisation may incorporate conjunctural analysis, in the process situating recent trends towards the use of land value capture mechanisms within the contradictions and statecraft of contemporary neoliberal urbanism.

Insight Into

By using CoMFA and CoMSIA methods, the new quantitative structures of 25 aromatic hydrocarbons and the 96 hr-EC50 data with C. vulgaris have been investigated to obtain more detailed insight into the relationships between molecular structure and bioactivity. Compared to CoMFA (the average Q2LOO option =0.610), CoMSIA (the average Q2LOO =0.736) has the better results with robustness and stability. CoMSIA analysis using steric, electrostatic, hydrophobic, and H-bond donor and acceptor descriptors show H-bond donor is the common factor for influencing the toxicity, the steric and electrostatic descriptors are next and the hydrophobic descriptor was last. From the contour maps, the number of benzene ring is more crucial for the compound toxicity and the compounds with more benzene ring make toxicity increased. Under the same number of benzene ring, the kind of substituent group and the formed ability of H-bond are the other parameters to influencing the aromatic hydrocarbons toxicity.

The Common European Framework of Reference (CEFR) was designed with adults in mind, which is clearly reflected in the six levels encompassing a range of proficiency that represents lifelong learning. Therefore, any use of the CEFR levels as a basis for describing the ability of young learners requires adapting the content of each level, as well as identifying which levels on the scale are appropriate for children.The present article examines the contribution that feedback, in the form of an assessment scale, can make to valid classroom assessment of the writing of young learners, in the age group of 9–13 years. It shows that a scale of descriptors adapted from the CEFR can play a central role in this assessment. The article presents the AYLLIT (Assessment of Young Learner Literacy) research project, which developed a CEFR-based writing scale and guidelines for teachers, enabling them to provide their students with feedback, and to gain a clearer insight into their students’ progress. After describing the procedures followed in the project, the article examines the extent to which its outcomes may enable teachers to give feedback that could contribute to valid classroom assessment.
