AbstractBody weight control is thought to be improved when physical activity and energy intake are both high (high energy turnover (ET)). The aim of the present study was to investigate the short-term impact of ET on fat balance during zero energy balance (EB), energetic restriction (ER) and overfeeding (OF). In a randomised crossover study, nine healthy men (BMI: 23·0 (SD 2·1) kg/m2, 26·6 (SD 3·5) years) passed 3 × 3 d in a metabolic chamber: three levels of ET (low, medium and high; physical activity level = 1·3−1·4, 1·5−1·6 and 1·7−1·8) were performed at zero EB, ER and OF (100, 75 and 125 % of individual energy requirement). Different levels of ET were obtained by walking (4 km/h) on a treadmill (0, 165 and 330 min). Twenty-four-hour macronutrient oxidation and relative macronutrient balance (oxidation relative to intake) was calculated, and NEFA, 24-h insulin and catecholamine secretion were analysed as determinants of fat oxidation. During EB and OF, 24-h fat oxidation increased with higher ET. This resulted in a higher relative fat balance at medium ET (EB: +17 %, OF: +14 %) and high ET (EB: +23 %, OF: +17 %) compared with low ET (all P < 0·05). In contrast, ER led to a stimulation of 24-h fat oxidation irrespective of ET (no differences in relative fat balance between ET levels, P > 0·05). In conclusion, under highly controlled conditions, a higher ET improved relative fat balance in young healthy men during OF and EB compared with a sedentary state.

AbstractThe area of dry-season rice (Oryza sativa L.) has rapidly increased in Cambodia owing to the large-scale development of irrigation infrastructure. But little is known of potential productivity and adaptive crop management. The objective of our study was to evaluate potential yield and nutrient requirements of dry-season rice in Cambodia, and the economic feasibility of soil-specific management recommended by the government. Field experiments were conducted on four soil types (Bakan, equivalent to Alfisol; Krakor, Inceptisol; Prateah Lang, Plinthustalfs; and Toul Samroung, Endoaqualfs) in four provinces (Battambang, Kampong Thom, Pursat, and Siem Reap) during the 2016 and 2017 dry seasons to compare 14 (2016) and 8 (2017) N-P-K combinations. Grain yield ranged from 1.0 to 5.5 t ha−1 in 2016 and from 1.3 to 6.7 t ha−1 in 2017. Potential yield from the experiments was 6–7 t ha−1 on Toul Samroung soil, 5–6 t ha−1 on Bakan soil, and 3–5 t ha−1 on Prateah Lang and Krakor soils. A rate of 140-60-60 kg ha−1 of N-P2O5-K2O was more than enough to achieve the best yields on any soil group. On the other hand, modest application rates in soil-specific management (44–78 kg ha−1 of N, 23–28 kg ha−1 of P2O5, 0–30 kg ha−1 of K2O) proved reasonable for resource-poor farmers in Cambodia, since the treatment always provided >75 % of the highest economic profit in high-input plots.
Columbus, Juana and the Politics of the Plaza: Battles over Monuments, Memory and Identity in Buenos Aires
Authors: Frei Cheryl Jiménez 
Published: October 2019

AbstractIn 2013, Argentina's then-President Cristina Fernández de Kirchner sparked controversy for her decision to replace a monument of Christopher Columbus in Buenos Aires with one of nineteenth-century mestiza revolutionary Juana Azurduy. This article examines the history and iconography of these monuments, exploring the intersections between public space, art, politics and memory. It argues that these monuments — one representing Argentina's previously maligned Italian immigrant heritage, the other its forgotten indigenous culture — demonstrate how fundamental struggles over national identity have been embedded and contested in the capital's urban landscape, in ways that remain influential. It highlights Argentina's 1910 centennial and 2010 bicentennial as key to these efforts, and examines the power/politics of place in the central plaza where various actors have fought for public commemorative representation.
Searching for ghosts: fluidity and temporal expansion in Joni Mitchell's first five albums (1968–1972)
Authors: Ford Charles 
Published: October 2019

AbstractHaving first raised questions of musical evaluation, and introduced my analytical approach, I proceed to an empirical, in the sense of more-or-less objective, analysis of the metric and melodic aspects of the songs on those five LPs that constitute Joni Mitchell's early style: Song to a Seagull (1968), Clouds (1969), Ladies of the Canyon (1970), Blue (1971) and For the Roses (1972). The results of this style analysis are then summarised. Next I proceed to a more phenomenologically inclined examination of ethereal, since evanescent or ‘ghostly’, ‘haunting’ characteristics of musical fluidity and expansion in Mitchell's music. Such passages of ‘stretched’ musical time arise from several properties: regulated yet ambiguous metric irregularity, swinging around the beat and melodic flow. The essay concludes with close examinations of the longest and most fluid musical properties of ‘Willy’ (Ladies of the Canyon) and ‘Case of You’ (Blue).
‘Shrieking soldiers … wiping clean the earth’: hearing apocalyptic environmentalism in the music of Botanist
Authors: Lucas Olivia R. 
Published: October 2019

AbstractThis article presents a case study of ecocritical black metal, delving into the apocalypticism of the California-based black metal band Botanist, who conjures a world in which plants have violently destroyed human civilisation. It first contextualises Botanist amidst the broader current of environmentalism in extreme metal as well as within wider cultural explorations of plants as subjective beings capable of violence. The article then examines how Botanist taps into the logic of apocalyptic environmentalism, as the music presents the essential narrative of apocalyptic bioterrorism: humanity, with wanton hubris, has sown the seeds of its own destruction, and earned whatever horrors befall it on the way to elimination. With its bleak outlook and strident sound world, Botanist's music threatens to destabilise listeners’ assumptions about their place in the world and offers an example of what apocalyptic ecological urgency in music could sound like.
‘Kollegah the Boss’: A case study of persona, types of capital, and virtuosity in German gangsta rap
Authors: Ahlers Michael 
Published: October 2019

AbstractThe article begins with a short history of German gangsta rap, followed by an overview of central theories and key concepts in hip-hop studies. It then focuses on a case study of a German gangsta rapper called Kollegah, who became one of Germany's most commercially successful artists of the past few years. The case study is divided into three parts: the first involves a deconstruction of both his artistic persona and his strategies of appropriating hip-hop cultures. This is followed by a closer look at two Kollegah productions, focusing on his rhyming and signifying skills. By adding a cursory qualitative media analysis of both Internet fan forums and print and television artefacts about Kollegah, very contradictory reactions can be depicted. The article is finally able to illustrate that this artist makes great use of a (typically German?) flavour of virtuosity and that he can draw from a very unique set of capital. Kollegah is viewed as representing a successful strategy of cultural appropriation and the use of different types of capital within the network of music business in its post-digital era.

AbstractLitter breakdown is an important ecological process at the bottom of food webs in streams. Previous studies have been based only on a temporal interval of a single season, thus ignoring seasonal variation in litter input and community structure. We investigated organic matter input in a Brazilian savanna stream and the influence of its associated hyphomycetes on the invertebrate community. Organic matter input was sampled monthly and the leaves submitted to decomposition experiments. There were lower breakdown rates and higher invertebrate species richness and abundance during the dry season, which reached their maximum in July due to low stream discharge. Invertebrate composition was best explained by hyphomycetes (mainly byFlagellospora curvulaandAnguillospora filiformis). Hyphomycetes have the capacity to degrade complex compounds of litter and to rapidly absorb nutrients by growing branched filaments, thus making the leaves more favourable for consumption by invertebrates. Shredder abundance was negatively related to litter richness, indicating possible species-specific relationships. We observed a sequential process with increased leaf litter input promoting an increase in hyphomycetes biomass, which in turn favoured invertebrate density.
Learning to construct sentences in Spanish: a replication of the Weird Word Order technique
Authors: AGUADO-OREA Javier , WITHERSTONE Hannah , BOURGEOIS Lisa , BASELGA Ana 
Published: October 2019

AbstractIn the present study, children's early ability to organise words into sentences was investigated using the Weird Word Order procedure with Spanish-speaking children. Spanish is a language that allows for more flexibility in the positions of subjects and objects, with respect to verbs, than other previously studied languages (English, French, and Japanese). As in prior studies (Abbot-Smithet al., 2001; Changet al., 2009; Francket al., 2011; Matthewset al., 2005, 2007), we manipulated the relative frequency of verbs in training sessions with two age groups (three- and four-year-old children). Results supported earlier findings with regard to frequency: children produced atypical word orders significantly more often with infrequent verbs than with frequent verbs. The findings from the present study support probabilistic learning models which allow higher levels of flexibility and, in turn, oppose hypotheses that defend early access to advanced grammatical knowledge.
CROCODILES, SHARKS, AND SOME SPECULATIONS ON CENTRAL PETEN PRECLASSIC HISTORY
Authors: Rice Prudence M. 
Published: October 2019

AbstractThe first part of this two-part essay discusses the important roles crocodiles and sharks played in Preclassic (and later) political geography and myths of cosmogenesis in Mesoamerica. They are associated with sacrifices resulting in creation of the world and births of some major gods. Crocodiles are also associated with fertility, rebirth, and renewal of seasonal and temporal/calendrical cycles. Recent investigations at Nixtun-Ch'ich’ show that its gridded urban landscape, established in the Middle Preclassic period (ca. 800–400b.c.), was likely modeled on a crocodile's back. The second part of the essay presents some speculations on the early role of this site and crocodiles in central Peten. At Tikal, archaeology and retrospective texts indicate that crocodiles appeared in early versions of the site's emblem glyph and in the name of an early ruler. Nixtun-Ch'ich’ might be the legendarychiplace, important in the dynastic foundations of several lowland Maya centers.
PROBLEMATICAL DEPOSITS AT TIKAL, GUATEMALA: CONTENT, CONTEXT, AND INTENT
Authors: Moholy-Nagy Hattula 
Published: October 2019

AbstractIn the Mesoamerican archaeological literature, collections of material regarded as somehow anomalous according to the archaeologist's expectations are often referred to as problematical deposits (PDs). Their problematical aspect originates in the researcher's current state of knowledge of the particular site, not in past behavior. PDs are site-specific, provisional classifications, and need further study to determine the function or intent of the activity that created them. A sample of 223 features designated as PDs by the University of Pennsylvania Museum's Tikal Project is examined here in an approach to understand their intent. A typology of the sample, based upon content, date, and variables of recovery context, indicates three principal intents broadly summarized as ritual, political, and site maintenance, and a category of PDs without intent. The study of PDs demands a wide-ranging approach. It provides an opportunity to reevaluate inadequate ideas and gain new insights into past cultural behavior.
Adapting the motet(s)? The case of Hé bergier in Oxford MS Douce 308
Authors: LEACH ELIZABETH EVA 
Published: October 2019

AbstractThe present article seeks to further recent discussion of the diversity of the motet in the long thirteenth century by considering a specific, rather unusual example of motet-related materials in a songbook. It examines a two-stanza pastourelle in the songbook that forms part of Oxford, Bodleian Library, MS Douce 308, and its connection to a network of related materials in various thirteenth-century motet sources. In so doing, it proposes the ostensibly unlikely scenario that this monophonic song derives from two separate motets that may already have been linked through their shared tenor and possibly also performed together in some way. This article brings the important conclusions of Fred Büttner in regard to these materials to Anglophone scholarship, while nuancing his reasoning in light of more recent scholarly work on thirteenth-century motets copied in songbooks.
What makes a ban on plastic bags effective? The case of Nepal
Authors: Bharadwaj Bishal , Baland Jean Marie , Nepal Mani 
Published: October 2019

AbstractThe extensive use of plastic bags in Nepal has led to growing concern in recent years. We investigate the impact of a municipal plastic bags ban on bags use behavior, based on a field survey carried out among consumers and retailers across selected municipalities. Our results indicate that the effectiveness of the ban critically depends on its enforcement and sanctioning system. In particular, our results suggest that the perceived sanction is a critical determinant of plastic bags use, as a doubling of the perceived sanction could reduce plastic bags use by two-thirds for retailers and by one-half for consumers. While the nominal amount of the fine does not seem to play a role, the probability of being detected appears to play a key role in the perceived sanction. This implies that effective monitoring of the ban by the municipal authorities is critical for the success of the policy.
DEFINABLE SETS OF BERKOVICH CURVES
Authors: Cubides Kovacsics Pablo , Poineau Jérôme 
Published: October 2019

AbstractIn this article, we functorially associate definable sets to$k$-analytic curves, and definable maps to analytic morphisms between them, for a large class of$k$-analytic curves. Given a$k$-analytic curve$X$, our association allows us to have definable versions of several usual notions of Berkovich analytic geometry such as the branch emanating from a point and the residue curve at a point of type 2. We also characterize the definable subsets of the definable counterpart of$X$and show that they satisfy a bijective relation with the radial subsets of$X$. As an application, we recover (and slightly extend) results of Temkin concerning the radiality of the set of points with a given prescribed multiplicity with respect to a morphism of$k$-analytic curves. In the case of the analytification of an algebraic curve, our construction can also be seen as an explicit version of Hrushovski and Loeser’s theorem on iso-definability of curves. However, our approach can also be applied to strictly$k$-affinoid curves and arbitrary morphisms between them, which are currently not in the scope of their setting.
Establishment of the early-life microbiome: a DOHaD perspective
Authors: Stinson Lisa F. 
Published: October 2019

AbstractThe human microbiome plays a number of critical roles in host physiology. Evidence from longitudinal cohort studies and animal models strongly supports the theory that maldevelopment of the microbiome in early life can programme later-life disease. The early-life microbiome develops in a clear stepwise manner over the first 3 years of life. During this highly dynamic time, insults such as antibiotic use and formula feeding can adversely affect the composition and temporal development of the microbiome. Such experiences predispose infants for the development of chronic health conditions later in life. This review highlights key factors that disrupt the early-life microbiome and highlights major non-communicable diseases which are underpinned by early-life dysbiosis.
Underestimation of Global Photosynthesis in Earth System Models Due to Representation of Vegetation Structure

Published: October 2019

AbstractThe impact of vegetation structure on the absorption of shortwave radiation in Earth System Models (ESMs) is potentially important for accurate modeling of the carbon cycle and hence climate projections. A proportion of incident shortwave radiation is used by plants to photosynthesize and canopy structure has a direct impact on the fraction of this radiation which is absorbed. This paper evaluates how modeled carbon assimilation of the terrestrial biosphere is impacted when clumping derived from satellite data is incorporated. We evaluated impacts of clumping on photosynthesis using the Joint UK Land Environment Simulator, the land surface scheme of the UK Earth System Model. At the global level, Gross Primary Productivity (GPP) increased by 5.53 ± 1.02 PgC/year with the strongest absolute increase in the tropics. This is contrary to previous studies that have shown a decrease in photosynthesis when similar clumping data sets have been used to modify light interception in models. In our study additional transmission of light through upper canopy layers leads to enhanced absorption in lower layers in which photosynthesis tends to be light limited. We show that this result is related to the complexity of canopy scheme being used.
Acceleration of the Extreme Sea Level Rise Along the Chinese Coast

Published: October 2019

AbstractUsing high‐frequency tide gauge observations from 1980 to 2017, we analyzed changes in extreme sea levels (ESLs) along the Chinese coast to examine whether extreme sea‐level rise acceleration could be observed. The results indicated that the ESL has risen with fluctuations along the Chinese coast. The ESL also featured significant decadal variabilities. The ESL rise was accelerated at most tide gauges throughout the whole study period, especially after the 1980s, while the acceleration patterns varied with station location. The mean sea level (MSL) change was confirmed as the major driver of the ESL change according to the analysis. However, the skew surge may also have affected the extremes at many of the tide gauges, which was observed after detrending. The extreme/MSL had a significant positive correlation with the Atlantic Multidecadal Oscillation, which is supposed to affect the MSL through a combination of variation in sea surface temperature, pressure system, and wind. That sea level oscillation is dominated by Atlantic Multidecadal Oscillation should be taken into consideration when studying accelerations in the rate of ESLs and of MSLs along the Chinese coast.
Broader Impacts of the Metasomatic Underplating Hypothesis
Authors: Park Jeffrey , Rye Danny M. 
Published: October 2019

AbstractThe “metasomatic underplating” hypothesis argues that crustal fractures develop during hot spot magma ascent to allow seawater to infiltrate and to serpentinize the sub‐Moho mantle. Published seismic velocities and layer thicknesses support estimates that 1 km of seawater could be chemically bound within an underplated layer, which may require 2–4 Myr to mature. If a serpentinized mantle layer underlies hot spot tracks and/or aseismic ridges, their buoyancy can induce flat‐slab behavior within subduction zones (e.g., beneath central Chile and Peru), weaken slab rheology, and foster slab tears. During serpentinization, metasomatic underplating would produce more serpentine and talc and less brucite and magnetite, if seawater equilibrates with silica in the gabbroic oceanic crust as it descends to the Moho. The restricted solubility of carbonate with temperature may induce seawater CO2 to sequester in the crust as carbonate concretions or intergrowths. Consumption of seawater H2O by serpentinization raises its salinity so that Fe cations stabilize in chloride complexes and depart the open system. Alkali cations in seawater contribute to the sodic metasomatism of pyroxenes, analogous to alterations observed in abyssal peridotites.
The Role of Winter Warming in Permafrost Change Over the Qinghai‐Tibet Plateau

Published: October 2019

AbstractWinter warming is fast than summer warming on the Qinghai‐Tibet Plateau (QTP). However, no assessment of winter warming effects on permafrost has been attempted. Here we conducted hypothetical control experiments and used the Noah land surface model to evaluate the impacts of winter warming on the QTP permafrost. The results show that air temperature in winter (November–April) was increasing at a rate of 0.66 °C/decade during 1980s−2000s, over double that in summer (May–October). The mean annual ground temperature of permafrost increased by 0.13 °C/decade. The summer warming dominated the variations in thermal regime of permafrost before 2000. After that, the influence of winter warming on permafrost thermal regime has gradually grown and exceeded that of summer warming. Winter warming has amplified the thermal degradation of permafrost. Our findings reveal that alpine continuous permafrost on the northern QTP has experienced a prominent regional warming due to rapid winter warming since 2000.
Short‐ and Long‐Wavelength TIDs Generated by the Great American Eclipse of 21 August 2017

Published: October 2019

AbstractOn the 21 August 2017 the eclipse shadow drastically changed the state of the ionosphere over the United States. This effect on the ionosphere is visible in the total electron content measured by Global Navigation Satellite Systems (GNSS). The shadow moved with the supersonic speed of ~1,000 m/s over Oregon to ~650 m/s over South Carolina. In order to exhaustively explore the ionospheric signature of the eclipse, we use data of total electron content from ~3,000 GNSS stations seeing multiple Global Positioning System (GPS) and Global Navigation Satellite System (GLONASS) satellites to visualize the phenomena. This tremendous dataset allows high‐resolution characterization of the frequency content and wavelengths—using an omega‐k analysis based on 3‐D fast Fourier transform—of the eclipse signature in the ionosphere in order to fully identify traveling ionospheric disturbances (TIDs). We confirm the generation of TIDs associated with the eclipse including TIDs interpreted as bow waves in previous studies. Additionally, we reveal, for the first time, short (50–100 km) and long (500–600 km) wavelength TIDs with periods between 30 and 65 min. The sources of the revealed short wavelength TIDs are co‐located with the regions of stronger gradient of the EUV related to sunspots. Our work confirms and describes physical properties of the waves observable in the ionosphere during the Great American Eclipse.
