Why Was the Wheel (Not) Used in the Andes? A Hypothesis Explaining the Slow Adoption of Wagon Transport and Evidence from Nineteenth-Century Colombia
The slow adoption of wagon transport in the Andes is a puzzle. We examine it by developing a threshold technology-adoption model calibrated using human and mule energy consumption and unique historical data from a human trail and the first wagon road in the Andes. Model predictions align with historical social choices. Pre-Columbians selected a straight, steep, short route for human porters to reduce energy costs, while the Spanish used it with m…
A cross-sectional survey of psychiatrists’ experiences of using telepsychiatry during the Covid-19 pandemic and the relationship with burnout in selected high, middle, and low-income countries
Background: The COVID-19 pandemic necessitated substantial modifications in the delivery of patient care on a global scale. Telemedicine-based care services were implemented worldwide to maximize access to healthcare systems. Aims: This study aimed to investigate the use of and satisfaction with telepsychiatry services implemented during the COVID-19 pandemic by psychiatrists across low, middle, and high income countries, and to assess levels of …
Dispensation of outpatient hospital medicines by hospital only versus hospital-community pharmacies collaboration
Goal To describe the experience of a dispensing model of outpatient hospital medicines (OHM) via collaboration of hospital and community pharmacies, and to explore patient satisfaction with the strategy as compared with the hospital pharmacy only service. Background Patient satisfaction is an important component of the quality of health care. Study A new model of dispensing OHM was conducted in the Outpatients Unit of the Service of Hospital Phar…

Covid ‐19 vaccination coverage and vaccine hesitancy among people with opioid use disorder in Barcelona, Spain
Phenotypic Clustering in Non-Cystic Fibrosis Bronchiectasis Patients
Whether high blood eosinophil counts may define a better phenotype in bronchiectasis patients, as shown in chronic obstructive pulmonary disease (COPD), remains to be investigated. Differential phenotypic characteristics according to eosinophil counts were assessed using a biostatistical approach in a large cohort study from the Spanish Online Bronchiectasis Registry (RIBRON). The 906 patients who met the inclusion criteria were clustered into tw…
The arrival of wagons to the Andes
The slow adoption of wagon roads on the Andes is an event widely noted. In this article we document the arrival of the first wagon road to the Andes: the Cambao wagon road connecting Bogotá to the Magdalena river valley in 1885. The road projects, its construction and traffic once it opened are presented and discussed using a variety of newly identified archival sources. It is argued that the historic and economic significance of this technologic…
Relation between Length of Exposure to Epidural Analgesia during Labour and Birth Mode
The length of exposure to epidural analgesia during labour is associated with non-spontaneous births in our study. It highlights the need for practice change through the development of clinical guidelines, training programs for professionals and the continuity of midwifery care in order to support women to cope with labour pain using less invasive forms of analgesia. Women also need to be provided with evidence-based information
Trends in Aids Mortality, Retention in Opioid Agonist Therapy, and HIV RNA Suppression in HIV-Infected People Who Injected Drugs from 2000 to 2015
Holding Up the Empire
Why did the United States subsidize American multinationals' entry into countries treated as informal colonies? We study a classic case of American imperialism, the 1903 U.S. support of Panama's secession from Colombia and subsequent U.S. payment of the 1921 reparations that opened Colombia's oil fields to Standard Oil. We test Noel Maurer's (2013) empire trap hypothesis quantitatively. Archival and econometric evidence documents Colombia's threa…
The First U.S. Transcontinental Railroad
Construction of the first transcontinental railroad, financed with large federal subsidies, is an important event in American history. Were the subsidies necessary to induce private investment in the railroad? The ex-ante investment decision examined uses contemporary reports and a simulation model to show that investors expected the railroad to be profitable. Evidence also shows that the railroad created political conflicts in Congress between t…
Chapter Fourteen. Characterization Of Technological Change In The Shipping Industry, 1350–1800
The present chapter includes contributions to understanding of the nature, the sources and effects of technological change on the European shipping industry between the fourteenth and the nineteenth centuries. Most of the contributions included in the volume have been presented in the form of narratives. There are two different ways in which peace directly led to shipping productivity growth. First, peace had positive effects on ship-technologica…
Chapter Twelve. Total Factor Productivity For The Royal Navy From Victory At Texel (1653) To Triumph At Trafalgar (1805)
The size and strength of the Royal Navy experienced a punctuated evolution into the largest and most powerful Navy in the world by 1815. Most historians tend to represent its superiority in conflicts at sea as an indication of several factors that would be conceptualized by economists as residuals in a production function, namely: better technologies, efficient seamanship, bravery in battle, the Nelson factor, strong logistical support on shore a…
