Research performance and age explain less than half of the gender pay gap in New Zealand universities

by Ann Brower, Alex James

We use a globally unique dataset that scores every individual academic’s holistic research performance in New Zealand to test several common explanations for the gender pay gap in universities. We find a man’s odds of being ranked professor or associate professor are more than double a woman’s with similar recent research score, age, field, and university. We observe a lifetime gender pay gap of ~NZ$400,000, of which research score and age explain less than half. Читать дальше...

Mortality and demographic recovery in early post-black death epidemics: Role of recent emigrants in medieval Dijon

by Pierre Galanaud, Anne Galanaud, Patrick Giraudoux, Henri Labesse

Objective and methods

We analyze the influence of population movement on susceptibility to death and resilience during two epidemics occurring in Dijon soon after the Black Death. Using a specific program designed to propose links between entries in annual tax registers, we define tentative heads of household, the elapsed time since their first registration and their ties with other persons within the city.

Measuring the diffusion of innovations with paragraph vector topic models

by David Lenz, Peter Winker

Measuring the diffusion of innovations from textual data sources besides patent data has not been studied extensively. However, early and accurate indicators of innovation and the recognition of trends in innovation are mandatory to successfully promote economic growth through technological progress via evidence-based policy making. In this study, we propose Paragraph Vector Topic Model (PVTM) and apply it to technology-related news articles to analyze innovation-related... Читать дальше...

Copper to Tuscany – Coals to Newcastle? The dynamics of metalwork exchange in early Italy

by Andrea Dolfini, Ivana Angelini, Gilberto Artioli

The paper discusses results of an interdisciplinary research project integrating lead isotope, chemical, and archaeological analysis of 20 early metal objects from central Italy. The aim of the research was to develop robust provenance hypotheses for 4th and 3rd millennia BC metals from an important, yet hitherto neglected, metallurgical district in prehistoric Europe, displaying precocious copper mining and smelting, as well as socially...

Mugharat an-Nachcharini: A specialized sheep-hunting camp reveals high-altitude habitats in the earliest Neolithic of the Central Levant

by Stephen Rhodes, E. B. Banning, Michael Chazan

The earliest Neolithic of southwest Asia is generally perceived and portrayed as a period of emerging economic practices that anticipated full-fledged food-producing economies. This first Neolithic, however, can also be seen as the last gasp of an earlier way of life that remained fundamentally Epipaleolithic in character. While people at this time had begun to cultivate some of the plant foods gathered in preceding periods, and to live for... Читать дальше...

7,200 years old constructions and mudbrick technology: The evidence from Tel Tsaf, Jordan Valley, Israel

by Danny Rosenberg, Serena Love, Emily Hubbard, Florian Klimscha

The history of mudbrick production and construction in the southern Levant may be dated as far back to the Pre-Pottery Neolithic A. However, at many of the sites where mudbrick remains were noted, their preservation was poor, so investigation of their production and the related construction techniques in antiquity was precluded. The 7,200 year old (cal BP) site of Tel Tsaf, located in the Jordan Valley, is distinguished by outstanding preservation of mudbrick architecture... Читать дальше...

Modeling migration patterns in the USA under sea level rise

by Caleb Robinson, Bistra Dilkina, Juan Moreno-Cruz

Sea level rise in the United States will lead to large scale migration in the future. We propose a framework to examine future climate migration patterns using models of human migration. Our framework requires that we distinguish between historical versus climate driven migration and recognizes how the impacts of climate change can extend beyond the affected area. We apply our framework to simulate how migration, driven by sea level rise, differs from baseline migration patterns. Читать дальше...

High-order radiomics features based on T2 FLAIR MRI predict multiple glioma immunohistochemical features: A more precise and personalized gliomas management

by Jing Li, Siyun Liu, Ying Qin, Yan Zhang, Ning Wang, Huaijun Liu

Objective

To investigate the performance of high-order radiomics features and models based on T2-weighted fluid-attenuated inversion recovery (T2 FLAIR) in predicting the immunohistochemical biomarkers of glioma, in order to execute a non-invasive, more precise and personalized glioma disease management.

Methods

51 pathologically confirmed gliomas patients committed in our hospital from March 2015 to June 2018 were retrospective analysis... Читать дальше...
