Abstract
Purpose
Literature reported that soils characterized by heterogeneity would reveal the different direction of clay minerals transformation. Hence, in this study, four soils developed on menilite shales slope deposits were investigated to test if the clay minerals transformations in soils with varied calcium carbonate distribution would show multidirectional paths of clay mineral weathering, or if transformation of secondary phases in such stratified materials would reveal only one trajectory.

Methods
The separated clay fractions were analysed using X-ray diffractometry and Fourier-transform infrared spectroscopy. Geochemical analyses were performed using ICP-ES and ICP-MS after sample fusion with lithium borate and an alloy dissolution with nitric acid.

Results
Calcium carbonate did not influence the composition and transformation of clay minerals. Despite the fact that soils were characterized by different content and distribution of calcium carbonate within the solum and additionally indicated various morphological features, the mineralogical composition of clay fraction was very uniform. Among the secondary phases, chlorite, illite, vermiculite, kaolinite and mixed phases illite-smectite and vermiculite-chlorite were detected in all horizons.

Conclusions
The uniform composition of the clay minerals in the studied soils suggested that mass movement, which controlled the formation of slope covers, was probably of a similar character and intensity across the whole of the slope. Furthermore, it seems that the pedogenesis in all soils proceeded on the same scale of advancement. This was indicated by a similar degree of weathering of soil material and lack of depth-dependent weathering in the profiles, confirmed by values of weathering indices (CIA and ICV) as well as by micromorphologically visible, highly weathered coarse fragments. Moreover, weak intensity of the illuviation process within the homogeneous substrate could have resulted in the very uniform composition of clay minerals in the studied soils.

Abstract
Background
Questions persist about how learning healthcare systems should integrate audit and feedback (A&F) into quality improvement (QI) projects to support clinical teams’ use of performance data to improve care quality.

Objective
To identify how a virtual “Hub” dashboard that provided performance data for patients with transient ischemic attack (TIA), a resource library, and a forum for sharing QI plans and tools supported QI activities among newly formed multidisciplinary clinical teams at six Department of Veterans Affairs (VA) medical centers.

Design
An observational, qualitative evaluation of how team members used a web-based Hub.

Participants
External facilitators and multidisciplinary team members at VA facilities engaged in QI to improve the quality of TIA care.

Approach
Qualitative implementation process and summative evaluation of observational Hub data (interviews with Hub users, structured field notes) to identify emergent, contextual themes and patterns of Hub usage.

Key Results
The Hub supported newly formed multidisciplinary teams in implementing QI plans in three main ways: as an information interface for integrated monitoring of TIA performance; as a repository used by local teams and facility champions; and as a tool for team activation. The Hub enabled access to data that were previously inaccessible and unavailable and integrated that data with benchmark and scientific evidence to serve as a common data infrastructure. Led by champions, each implementation team used the Hub differently: local adoption of the staff and patient education materials; benchmarking facility performance against national rates and peer facilities; and positive reinforcement for QI plan development and monitoring. External facilitators used the Hub to help teams leverage data to target areas of improvement and disseminate local adaptations to promote resource sharing across teams.

Conclusions
As a dynamic platform for A&F operating within learning health systems, hubs represent a promising strategy to support local implementation of QI programs by newly formed, multidisciplinary teams.
Enhanced indexation via chance constraints
Authors: Beraldi Patrizia , Bruni Maria Elena 
Published: September 2020

AbstractThe enhanced index tracking (EIT) represents a popular investment strategy designed to create a portfolio of assets that outperforms a benchmark, while bearing a limited additional risk. This paper analyzes the EIT problem by the chance constraints (CC) paradigm and proposes a formulation where the return of the tracking portfolio is imposed to overcome the benchmark with a high probability value. Besides the CC-based formulation, where the eventual shortage is controlled in probabilistic terms, the paper introduces a model based on the Integrated version of the CC. Here the negative deviation of the portfolio performance from the benchmark is measured and the corresponding expected value is limited to be lower than a given threshold. Extensive computational experiments are carried out on different set of benchmark instances.
Both the proposed formulations suggest investment strategies that track very closely the benchmark over the out-of-sample horizon and often achieve better performance. When compared with other existing strategies, the empirical analysis reveals that no optimization model clearly dominates the others, even though the formulation based on the traditional form of the CC seems to be very competitive.
The Easternmost European Palaeolithic Artists: Iconography and Graphic Features at Kapova Cave (Southern Urals, Russia)
Authors: Ruiz-Redondo Aitor , Yanovskaya Katherin , Zhitenev Vladislav S. 
Published: September 2020

AbstractPalaeolithic rock art is one of the most distinctive cultural traits of Upper Palaeolithic societies in Europe. Traditionally restricted to South-western Europe, especially to the Franco-Cantabrian province, in recent years, the geographic distribution of this phenomenon has noticeably expanded. Several years before these discoveries, the first decorated site found beyond southern Europe was Kapova cave, in Russia. This site, at the edge of the distribution area of European Palaeolithic art and far away from other cave sanctuaries, is key to define and understand potential long-distance cultural networks during the Upper Palaeolithic. In this paper, we present the first comprehensive inventory of the artworks, a renewed documentation of the graphic units (including the first digital tracings), the spatial distribution and the stylistic analysis of the different motifs. This led us to understand the role of Kapova within the Palaeolithic symbolism and to better integrate it in the Palaeolithic cultural dynamics.
GÖDEL DIFFEOMORPHISMS
Authors: FOREMAN MATTHEW 
Published: September 2020

AbstractIn 1932, von Neumann proposed classifying the statistical behavior of differentiable systems. Joint work of B. Weiss and the author proved that the classification problem is complete analytic. Based on techniques in that proof, one is able to show that the collection of recursive diffeomorphisms of the 2-torus that are isomorphic to their inverses is $\Pi ^0_1$-hard via a computable 1-1 reduction. As a corollary there is a diffeomorphism that is isomorphic to its inverse if and only if the Riemann Hypothesis holds, a different one that is isomorphic to its inverse if and only if Goldbach’s conjecture holds and so forth. Applying the reduction to the $\Pi ^0_1$-sentence expressing “ZFC is consistent” gives a diffeomorphism T of the 2-torus such that the question of whether $T\cong T^{-1}$ is independent of ZFC.
The German Federal Constitutional Court’s Exercise of Ultra Vires Review and the Possibility to Open an Infringement Action for the Commission
Authors: Poli Sara , Cisotta Roberto 
Published: September 2020

Abstract
The paper examines the possible opening of an infringement procedure against Germany as a result of the breaches that emerge from the declaration by the German Constitutional Court that the Court of Justice has acted ultra vires in the Weiss judgment (C-493/17). The proportionality assessment of the Public Sector Purchase Programme (PSPP) of the European Central Bank (ECB), carried by the Court of Justice, is contested by the domestic court. We recall that the Commission enjoys great discretion regarding the launch of an infringement action based upon Article 258 of the TFEU and may be reluctant to use its powers, considering the special position of the constitutional courts in the context of Article 267 TFEU as well as the present situation of emergency following the pandemic. Yet, the possibility to start an infringement procedure for breaches of Treaty obligations resulting from an incorrect interpretation of domestic courts was admitted in case C-129/00 Commission v. Italy and applied in two subsequent cases (C-154/08 Commission v. Spain and C-416/17 Commission v. France). As a result of the ruling of May 5, 2020, the Court of Justice may find that Germany failed to fulfil obligations stemming from Article 267 TFEU and the related case-law, Article 19 TEU, as well as Article 5(2) TEU. Other breaches concern the independence of the ECB and of the Bundesbank (being it a Member of the European System of Central Banks (ESCB) and of the Eurosystem) as defined in Articles 130, 282(3) TFEU and Article 7 of the Protocol (No. 4) on the Statute of the ESCB and of the ECB. We argue in favour of the violation of all these provisions read in conjunction with the duty of loyal cooperation, laid down in Article 4(3) TEU. Yet, we conclude that it is uncertain whether the Commission will open (or continue) an infringement procedure against Germany since the Bundesbank may act to satisfy the requests of the German Constitutional Court in relation to the proportionality of the PSPP. It is to be hoped that the German State organs will make sure that the PSPP may be continued, thus ensuring the functioning of the Eurozone, despite the attack of the BVerfG to the EU Judicature and to Weiss ruling in particular.
Against Bidimensional Supremacy in EU Constitutionalism
Authors: Perju Vlad 
Published: September 2020

AbstractScholarly consensus sees EU supremacy as “necessarily bidimensional”: the supranational dimension necessarily stands alongside the national dimension, which rejects the absolute and unconditional supremacy of EU law. I argue that this view of bidimensional supremacy is conceptually flawed and descriptively inaccurate. On the conceptual side, I identify the fallacy of symmetry (the idea that national and supranational perspectives on supremacy are similar in nature and equally reductionist), the fallacy of selection (the view that bidimensionalism alone can overcome what it perceives as an inevitable subjective bias in the choice between national and supranational supremacy claims), and the fallacy of construction (an originally shared popular sovereignty theory, which turns out to be riddled with biases that disrupt the equilibrium within the internally divided sovereign). On the interpretative side, I suggest that the empirical evidence in support of bidimensional supremacy is weaker than it is generally assumed. I then offer an interpretation of the PSPP judgment of the German Federal Constitutional Court, which holds a judgment of the Court of Justice of the European Union to be ultra vires, unlawful and thus non-binding. PSPP presents a problem of German origins and cast, rather than one stemming from the inner structure of EU constitutionalism. At most, PSPP represents a contingent, rather than necessary, and thus unexceptional instance of bidimensional supremacy.
AMS 14C DATING OF THE MAYAN CODEX OF MEXICO REVISITED

Published: September 2020

ABSTRACTThe Mayan Codex of Mexico (MCM), the only Mayan codex found in the 20th century, was unveiled in 1971 during the Ancient Maya Calligraphy exhibition at Club Grolier. The codex comprises 10 pages of bark paper in accordion format, coated with a layer of plaster on both sides. It illustrates the synodic cycles of Venus, with its four phases. Since its discovery, the MCM has been subject to controversy and discussions about its authenticity. In 2016, a group of specialists led by Baltazar Brito chief of the National Library of Anthropology and History, carried out an exhaustive study of the codex with the purpose of determining its temporality and authenticity. In this work, the pre-Columbian authenticity of the codex is verified by the radiocarbon (14C) technique using AMS. Two cleaning procedures were contrasted: the standard acid-base-acid (ABA) protocol and a second one with Soxhlet plus ABA. Results obtained when samples were prepared following ABA protocol only, placed the age of the bark paper between 991 and 1147 cal AD. The second cleaning method with Soxhlet plus ABA, resulted in younger ages, between 1159 and 1261 cal AD. However, we consider that when Sohxlet is used as part of the cleaning protocol, organic contaminants are reduced to a minimum, and 14C dates are more reliable. These results indicate that the vegetal support of the MCM belongs to Postclassical Mayan period and place it as the oldest known manuscript of America found to date.
UTOPIA/WUTUOBANGAS A TRAVELLING MARKER OF TIME
Authors: ANDOLFATTO LORENZO 
Published: September 2020

AbstractThis article argues for the understanding of ‘utopia’ as a cultural marker whose appearance in history is functional to the a posteriori chronologization (or typification) of historical time. I develop this argument via a comparative analysis of utopia between China and Europe. Utopia is a marker of modernity: the coinage of the wordwutuobang(‘utopia’) in Chinese around 1895 is analogous and complementary to More's invention of Utopia in 1516, in that both represent attempts at the conceptualizations of displaced imaginaries, encounters with radical forms of otherness – the European ‘discovery’ of the ‘New World’ during the Renaissance on the one hand, and early modern China's own ‘Westphalian’ refashioning on the other. In fact, a steady stream of utopian conjecturing seems to mark the latter: from the Taiping Heavenly Kingdom borne out of the Opium wars, via the utopian tendencies of late Qing fiction in the works of literati such as Li Ruzhen, Biheguan Zhuren, Lu Shi'e, Wu Jianren, Xiaoran Yusheng, and Xu Zhiyan, to the reformer Kang Youwei's monumental treatiseDatong shu. Altogether, these sketches of utopia provide an imaginary counterpoint to the co-produced regimes of historicity whose genealogies are being traced in this issue.

AbstractThe family Hippoboscidae is a less known group of blood-sucking flies. Deer ked are particularly important for animal health; they may act as potential vectors of disease to ungulates, and may transmit pathogens to animals and humans. The aim of this study was to investigate the presence of Trypanosoma (Megatrypanum) DNA in deer keds using molecular methods. Results prove the presence of Megatrypanum trypanosome DNA in the studied winged adult deer keds and this is the first detection of this pathogen in Lipoptena fortisetosa. In addition, this paper evidences the occurrence of L. fortisetosa in two new locations: one in the Białowieża Primeval Forest, and another in the Strzałowo Forest Inspectorate (Piska Forest), both in north-eastern Poland.
Social inequalities over the lifecourse and healthy ageing in Aotearoa/New Zealand: differences by Māori ethnicity and gender
Authors: Stephens Christine , Szabó Ágnes , Breheny Mary 
Published: September 2020

AbstractLifecourse approaches to healthy ageing recognise that health in older age is affected by long-term cumulative inequalities between socio-economic status (SES), gender and ethnicity groups, which begin in childhood. Combining longitudinal survey data with lifecourse history interviews from 729 older New Zealanders aged 61–81 (mean = 72, standard deviation = 4.5), we tested a lifecourse model of predictors of physical, mental and social health in older age. Latent growth curve and mediation analysis showed that the link between childhood SES and late-life health (over 10 years) was mediated by education, occupation and adult wealth. To account for the moderating effects of gender and ethnicity, we modelled the effects for sub-groups separately (225 non-Māori women, 158 Māori women, 219 non-Māori men and 127 Māori men). Childhood SES was an important predictor of later-life health, mediated by education and adult SES for all participants and for non-Māori men. However, there were significantly different pathways for Māori men and for women. Māori men and women and non-Māori women did not attain the same health benefits from higher childhood SES and education as non-Māori men. Findings point to the importance of considering the mediators of lifelong impacts on health in older age, and recognition of how membership of different socially structured groups produces different pathways to late-life health.
Learner autonomy in music performance practices

Published: September 2020

AbstractThe language of music shares a number of basic processing mechanisms with natural languages, yet studies of learner autonomy in music education are rare. This study aims to assess the effectiveness of fostering music students’ learner autonomy in performance practice through a series of curriculum changes. A mixed-methods approach, including a questionnaire survey and semi-structured interviews, was used to investigate two cohorts of music education students (N= 74) from Hong Kong. The analysis reveals the students’ autonomous learner characteristics, including the ability to formulate their own learning strategies, identify both musical and non-musical weaknesses and take appropriate steps to improve their performance skills.
Prosodic realizations ofnew,given, andcorrectivereferents in the spontaneous speech of toddlers
Authors: THORSON Jill C. , MORGAN James L. 
Published: September 2020

AbstractOur motivation was to examine how toddler (2;6) and adult speakers of American English prosodically realize information status categories. The aims were three-fold: 1) to analyze how adults phonologically make information status distinctions; 2) to examine how these same categories are signaled in toddlers’ spontaneous speech; and 3) to analyze the three primary acoustic correlates of prosody (F0, intensity, and duration). During a spontaneous speech task designed as an interactive game, a set of target nouns was elicited as one of three types (new, given, corrective). Results show that toddlers primarily used H* across information status categories, with secondary preferences for deaccentinggiveninformation and for using L+H* forcorrectiveinformation. Only duration distinguished information status, and duration, average pitch, and intensity differentiated pitch accent types for both adults and children. Discussion includes how pitch accent selection and input play a role in guiding prosodic realizations of information status.
Stød in unexpected morphological contexts in Standard Danish: An experimental approach to sound change in progress
Authors: Grønnum Nina , Pharao Nicolai , Basbøll Hans 
Published: September 2020

AbstractIn recent years stød has appeared in words where the current phonological and morphological principles of its distribution would exclude it. Thus, a disyllable like [ˈsiːðə]side‘page’ is without stød, also in a compound likebagside‘back page’, but it has lately been heard with stød:. In a controlled experiment, speakers were required to produce compounds consisting of an existing initial word succeeded by a final nonce noun. The results indicate that stød may be spreading in this context. Furthermore, its distribution across the 40 nonce nouns was found to be similar to its distribution among existing nouns in the vocabulary: There are more nonce nouns with stød (i) in the definite singular, (ii) especially with short stressed vowels, and (iii) particularly if the initial word is monosyllabic. A change is apparently underway which will eventually partially suspend a non-stød principle which relieves disyllabic lexemes of stød.

AbstractObjective:To compare the effects of a typical Food Distribution Program on Indian Reservations (FDPIR) diet with an FDPIR diet that meets Dietary Guidelines for Americans (DGA) on inflammation response, appetite and energy intake on a combination of American Indian (AI) and non-AI individuals.Design:A within-subjects, randomised, crossover design was used to compare two dietary conditions: (1) a FDPIR diet that met DGA and (2) a FDPIR diet that did not meet DGA. Each participant served as their own control and was exposed to both dietary conditions. Repeated-measures ANOVA and t tests assessed significance between the two dietary conditions.Setting:This took place in the Montana State University Nutrition Research Laboratory in the USA.Participants:Female and male participants (n 13) aged 18–55 years from the university and local community.Results:There were no significant differences in inflammatory response and appetite sensations between the two dietary conditions. Findings indicated that participants ate 14 % more (P < 0·01) kcal on a typical FDPIR diet compared with a FDPIR diet that met DGA.Conclusions:Higher energy intake during a typical FDPIR diet compared with a FDPIR diet that meets DGA may increase risk for obesity and nutrition-related diseases, including type 2 diabetes and other chronic inflammatory conditions.
