The IPUMS Multigenerational Longitudinal Panel (MLP) is a longitudinal population panel that links American censuses, surveys, administrative sources, and vital records spanning the period from 1850 to the present. This article explains the rationale for IPUMS MLP, outlines the design of the infrastructure, and describes the linking methods used to construct the panel. We then detail our plans for
Intracellular deposits of neurofibrillary tau tangles and extracellular Aβ plaques are closely associated with Alzheimer’s disease. The mapping of thermodynamic parameters, including solubility limits, indicates when a protein forms amyloid fibrils or remains in solution. This reveals the direction of change of the system and may help in understanding drift and steady states in living systems. Her
Geographers have shown how mobile phones are transforming urban economies in Africa by altering the temporal and spatial nature of commercial transactions. Less well documented is how young people in Africa are using mobile phones to navigate the interplay between personal hopes, social expectations, and financial uncertainty associated with urban life. Drawing on qualitative data from youth in tw
Studies of mining and urbanisation have been primarily conducted independently of one another, with limited consideration of the inter-linkages between the two. This analysis seeks to fill this gap by exploring the links between mining and urbanisation in a Ghanaian context. Ghana is an interesting case as it is both endowed with significant mineral wealth and is highly urbanised, with a long hist
Extractivism is a global phenomenon driven by the logic of capitalism that is manifested chiefly in mining, but also in agribusiness. Women around the world have emerged as leaders of resistance movements against extractivism. In this article, we question this recurrent theme in political ecology literature based on ethnographic fieldwork in southern Ecuador, where resistance has been less success
The preterite-present verb (ge)munan, meaning ‘to remember’ or ‘to be mentally active’, is attested throughout the Old English period (450-1150). Deriving from the Proto-Germanic preterite-present lexical verb munan, it belongs to a class of verbs many of which grammaticalised into modal auxiliaries during Old and Middle English. (Ge)munan itself appears to have undergone grammaticalisation, as su
Abstract Title: Responsibility Laundering: FIFA and the Discursive Maintenance of Legitimacy Course: Managing People, Knowledge and Change Authors: Aimar Soto and Jesper Laan Supervisor: John Murray Purpose: The purpose of this thesis is to investigate how global organisations maintain legitimacy when operating across multiple and conflicting normative environments. The study’s goal is to understa
Spatial representations are a fundamental aspect of cognition. It remains largely unknown when and why the capacity to neurally represent space first evolved. In this opinion article, we argue that a strong candidate for the earliest such representation is the encoding of head direction. Dedicated circuits that compute head direction by integrating self-motion and external cues have been described
Reflux of equimolecular amounts 2-aminobenzylamine and isatins in acetic acid produced indolo[3,2-c]quinolin-6-ones in good yields. A proposed mechanism involving initial formation of a spiro compound is given. This isolable intermediate subsequently rearranges via a sequential isocyanate ring opening and a cyclisation process to a urea derivative which finally cyclized to the indolo[3,2-c]quinoli
Pictures are typically better remembered than words, but explanations for this fact diverge. Some attribute picture superiority to more distinctive perceptual qualities, others to more efficient conceptual processing. In an effort to separate perceptual and conceptual factors, two groups were presented with mixed lists of pictures and words and were subsequently tested for recognition in either th
Recent climate change has sparked an interest in the timing of biological events, which is a general problem in life-history evolution. Reproduction in many organisms breeding in seasonal environments, e. g. migratory birds, is dependent on the exploitation of a short but rich food supply. If the seasonal timing of the food peak advances owing to climate change, then one would expect the bird to t
