The periodicity of the mutual position of celestial bodies in the Earth‐Moon‐Sun system is crucial to the functioning of life on Earth. Biological rhythms affect most of the processes inside ...organisms, and some can be recorded in skeletal remains, allowing one to reconstruct the cycles that occur in nature deep in time. In the present study, we have used ultra‐high‐resolution elemental ratio scans of Mg/Ca, Sr/Ca and Mn/Ca from the fossil, ca. 70 Ma old inoceramid bivalve Inoceramus (Platyceramus) salisburgensis from deep aphotic water and identified a clear regularity of repetition of the geochemical signal every of ~0.006 mm. We estimate that the shell accretion rate is on average ~0.4 cm of shell thickness per lunar year. Visible light–dark lamination, interpreted as a seasonal signal corresponding to the semilunar‐related cycle, gives a rough shell age estimate and growth rate for this large bivalve species supported by a dual feeding strategy. We recognize a biological clock that follows either a semilunar (model A) or a tidal (model B) cycle. This cycle of tidal dominance seems to fit better considering the biological behaviour of I. (P.) salisburgensis, including the estimated age and growth rate of the studied specimens. We interpret that the major control in such deep‐sea environment, well below the photic zone and storm wave base, was due to barotropic tidal forces, thus changing the water pressure.
During the first half of the 20th century, Bolivian anarchism reached an important and original development. Despite this, its peculiar print culture and absent collection prevented it from first ...producing and then preserving its documents, which has been decisive for the elaboration of the history, historiography and memory of that movement. Based on these documentary gaps or “silences” that find an explanation in an archival approach situated in a framework of power, in this article we propose to advance in a theoretical and historical definition of these concepts and to reflect on the strategies developed in Bolivian and foreign repositories that allowed us to build a corpus composed of documents (bibliography, hemerography and archival fonds) capable of replenish some of these missing parts. From this exploration, we will try to demonstrate that it is possible to contest and subvert, at least partially, the power in the archives. = Durante la primera mitad del siglo XX, el anarquismo boliviano alcanzó un importante y original desarrollo. Pese a ello, su cultura impresa peculiar y acervo ausente le impidieron producir primero y preservar después sus documentos, lo cual ha sido determinante para la elaboración de la historia, historiografía y memoria de dicho movimiento. Partiendo de esos vacíos documentales o “silencios” que hallan explicación en un abordaje del archivo situado dentro de una trama de poder, en este artículo nos proponemos avanzar en una definición teórica e histórica de tales conceptos y reflexionar sobre las estrategias desplegadas en los repositorios de Bolivia y del extranjero que nos permitieron construir un corpus compuesto de documentos (bibliografía, hemerografía y fondos de archivo) capaz de reponer algunas de esas piezas faltantes. A partir de esta exploración, intentaremos demostrar que es posible contestar y subvertir, al menos parcialmente, el poder en los archivos.
À partir d'une étude des manuscrits du Soleil placé en abîme, cet article revient sur la pratique de la métaphore chez Francis Ponge. Si, au fur et à mesure de la genèse de son œuvre, l'écrivain ...cherche à circonscrire le soleil par la métaphore, il fait face à une double tyrannie : celle du soleil et celle de l'image. Puisqu'il ne peut échapper ni à l'une, ni à l'autre, il lui faut posséder le soleil à l'intérieur de son propre système, et parasiter la toute-puissance des métaphores… par la métaphore.
Studying the manuscripts for Le Soleil placé en abîme, this article looks back at Francis Ponge's use of metaphor. If, as his work emerges, the writer seeks to circumscribe the sun through metaphor, he faces a twofold tyranny: that of the sun and that of the image. Since he can escape neither, he must integrate the sun within his own system and parasitize the omnipotence of metaphors… through metaphor.
In a fascinating epilogue, Targoff narrates the history of the discovery of Colonna's name among the Roman records of the Inquisition in the archives of the Congregation for the Doctrine of the ...Faith. Targoff's accessible book brims with intriguing vignettes and historical detail: the menu of a courtly wedding banquet; a day in the life of a convent; thumbnail descriptions of Neoplatonism, the Sack of Rome, the struggle for the Capuchin Order (of whom Colonna was a champion), and the format of a Renaissance book; salt taxes; and advice to pilgrims: “Dress poorly, so as to avoid having to pay endless tips” (129). What emerges in this prismatic portrait is the degree to which Colonna pursued a very public career and, equally, an enduring legacy, all the while refusing social norms such as remarriage and endeavoring to find refuge from the world among her sisters.
Artificial impervious areas are predominant indicators of human settlements. Timely, accurate, and frequent information on artificial impervious areas is critical to understanding the process of ...urbanization and land use/cover change, as well as of their impacts on the environment and biodiversity. Despite their importance, there still lack annual maps of high-resolution Global Artificial Impervious Areas (GAIA) with longer than 30-year records, due to the high demand of high performance computation and the lack of effective mapping algorithms. In this paper, we mapped annual GAIA from 1985 to 2018 using the full archive of 30-m resolution Landsat images on the Google Earth Engine platform. With ancillary datasets, including the nighttime light data and the Sentinel-1 Synthetic Aperture Radar data, we improved the performance of our previously developed algorithm in arid areas. We evaluated the GAIA data for 1985, 1990, 1995, 2000, 2005, 2010, and 2015, and the mean overall accuracy is higher than 90%. A cross-product comparison indicates the GAIA data are the only dataset spanning over 30 years. The temporal trend in GAIA agrees well with other datasets at the local, regional, and global scales. Our results indicate that the GAIA reached 797,076 km2 in 2018, which is 1.5 times more than that in 1990. China and the United States (US) rank among the top two in artificial impervious area, accounting for approximately 50% of the world's total in 2018. The artificial impervious area of China surpassed that of the US in 2015. By 2018, the remaining eight among the top ten countries are India, Russia, Brazil, France, Italy, Germany, Japan, and Canada. The GAIA dataset can be freely downloaded from http://data.ess.tsinghua.edu.cn.

This paper explores the holistic needs of First Nations people in the archives to control their cultural heritage materials with dignity and respect. It highlights the importance of the archives ...supporting Indigenous ways of knowing, being and doing. Indigenous people’s spiritual and emotional needs are addressed by considering the support for Indigenous people’s wellbeing in the archives. Models of social, emotional and cultural wellbeing are presented as alternatives to discussing the need for Indigenous cultural safety in the archives. A definition of
Indigenous wellbeing, sovereignty and archival sovereignty
