The Abandonment of the Assignment of Subject Headings and Classification Codes in University Libraries due to the Massive Emergence of Electronic Books // El abandono de la asignación de encabezamientos de materia y códigos de clasificación en las bibliotecas universitarias debido a la incorporación masiva del libro electrónico.

The massive and unstoppable emergence of electronic books in libraries has altered their organization. This disruptive technology has led to structural changes. Currently, an e-book exists only if its metadata exists. The objective of this article is to analyse the impact that the massive incorporation of electronic books in university library systems is having in the processes of assignment of subject headings and classification codes. We carried out a survey of more than six hundred libraries, which means almost all the university libraries in Portugal, Spain, England, United States, Brazil, Sweden, Norway, Finland and Australia. From the results obtained, it is deduced that: 1) librarians expect ebooks to be provided with descriptive metadata related to the subject headings and classification codes; 2) the bibliographic records provided by publishers/providers seem to be improvable; 3) the quality of the metadata provided by the providers does not seem to be taken into account when selecting publishers for the purchase; 4) the discovery tools are also clearly improvable; 5) it seems that there is no "frustration" or "stress" among librarians about the changes produced in relation to technical processes; and, 6) it does not seem that we are facing a paradigm shift motivated by these issues

Commerce, finance and statecraft

In the seventeenth and eighteenth centuries, historians of England pioneered a series of new approaches to the history of economic policy. Commerce, finance and statecraft charts the development of these forms of writing and explores the role they played in the period's economic, political and historiographical thought. Through doing so, the book makes a significant intervention in the study of historiography, and provides an original account of early-modern and Enlightenment history. A broad selection of historical writing is discussed, ranging from the work of Francis Bacon and William Camden in the Jacobean era, through a series of accounts shaped by the English Civil War and the party-political conflicts that followed it, to the eighteenth-century's major account of British history: David Hume's History of England. Particular attention is paid to the historiographical context in which historians worked and the various ways they copied, adapted and contested one another's narratives. Such an approach enables the study to demonstrate that historical writing was the site of a wide-ranging, politically charged debate concerning the relationship that existed – and should have existed – between government and commerce at various moments in England’s past

Fleet management strategies for urban Mobility-on-Demand systems

In recent years, the paradigm of personal urban mobility has radically evolved as an increasing number of Mobility-on-Demand (MoD) systems continue to revolutionize urban transportation. Hailed as the future of sustainable transportation, with significant implications on urban planning, these systems typically utilize a fleet of shared vehicles such as bikes, electric scooters, cars, etc., and provide a centralized matching platform to deliver point-to-point mobility to passengers. In this dissertation, we study MoD systems along three operational directions – (1) modeling: developing analytical models that capture the rich stochasticity of passenger demand and its impact on the fleet distribution, (2) economics: devising strategies to maximize revenue, and (3) control: developing coordination mechanisms aimed at optimizing platform throughput. First, we focus on the metropolitan bike-sharing systems where platforms typically do not have access to real-time location data to ascertain the exact spatial distribution of their fleet. We formulate the problem of accurately predicting the fleet distribution as a Markov Chain monitoring problem on a graph representation of a city. Specifically, each monitor provides information on the exact number of bikes transitioning to a specific node or traversing a specific edge at a particular time. Under budget constraints on the number of such monitors, we design efficient algorithms to determine appropriate monitoring operations and demonstrate their efficacy over synthetic and real datasets. Second, we focus on the revenue maximization strategies for individual strategic driving partners on ride-hailing platforms. Under the key assumption that large-scale platform dynamics are agnostic to the actions of an individual strategic driver, we propose a series of dynamic programming-based algorithms to devise contingency plans that maximize the expected earnings of a driver. Using robust optimization techniques, we rigorously reason about and analyze the sensitivity of such strategies to perturbations in passenger demand distributions. Finally, we address the problem of large-scale fleet management. Recent approaches for the fleet management problem have leveraged model-free deep reinforcement learning (RL) based algorithms to tackle complex decision-making problems. However, such methods suffer from a lack of explainability and often fail to generalize well. We consider an explicit need-based coordination mechanism to propose a non-deep RL-based algorithm that augments tabular Q-learning with a combinatorial optimization problem. Empirically, a case study on the New York City taxi demand enables a rigorous assessment of the value, robustness, and generalizability of the proposed approaches

The Papers of Thomas A. Edison

This newest volume in the acclaimed Papers of Thomas A. Edison covers one year in the life of America's greatest inventor—1878. That year Edison, whom a New York newspaper in the spring first called "the Wizard of Menlo Park," developed the phonograph, one of his most famous inventions; made a breakthrough in the development of telephone transmitters, which made the instrument commercially viable; and announced the advent of domestic electric lighting, with only a few weeks' worth of tinkering necessary to complete its design (the announcement sent gas-company stocks plummeting; the research and development went on for four years).These inventions brought Edison financial support for his work and attention from the public. In January investors in the Edison Speaking Phonograph Company agreed to fund development work on the phonograph. The invention made Edison internationally famous and in May he traveled to Washington, D.C., to show the phonograph at the National Academy of Sciences, to Congress, and to President Rutherford B. Hayes at the White House. That same month Western Union agreed to pay Edison an annual salary of $6,000 for his telephone inventions, although other support from the company declined following the death of its president, William Orton. The stress of unceasing public attention, including a trans-Atlantic dispute over the question of who invented the microphone, led an exhausted Edison to travel west during the summer to witness a solar eclipse but also to seek rest. His six-week trip took him to San Francisco and the Yosemite region of California. Edison began working on electric lighting after his return and in October the Edison Electric Light Company was formed to support his research

Navigating Copyright for Libraries – Purpose and Scope

Information is a critical resource for personal, economic and social development. Libraries and archives are the primary access point to information for individuals and communities with much of the information protected by copyright or licence terms. In this complex legal environment, librarians and information professionals operate at the fulcrum of copyright’s balance, ensuring understanding of and compliance with copyright legislation and enabling access to knowledge in the pursuit of research, education and innovation. This book, produced on behalf of the IFLA Copyright and other Legal Matters (CLM) Advisory Committee, provides basic and advanced information about copyright, outlines limitations and exceptions, discusses communicating with users and highlights emerging copyright issues. The chapters note the significance of the topic; describe salient points of the law and legal concepts; present selected comparisons of approaches around the world; highlight opportunities for reform and advocacy; and help libraries and librarians find their way through the copyright maze

The Typological Diversity of Morphomes: A Cross-Linguistic Study of Unnatural Morphology

This is the first typologically-oriented book-length treatment of morphomes, systematic morphological identities, usually within inflectional paradigms, that do not map onto syntactic or semantic natural classes. In the first half of the book, Borja Herce outlines the theoretical and empirical challenges associated with the identification and definition of morphomes, and surveys their links with related notions such as syncretism, homophony, segmentation, and economy, among others. He also presents the different ways in which morphomic structures in a language have been observed to emerge, change, and disappear. The second part of the book contains its core contribution: a database of 120 morphomes across 79 languages from a range of families, which are presented and analysed in detail. A range of findings emerge as a result, including the idiosyncratic nature of morphomes in the Romance languages, the existence of cross-linguistically recurrent unnatural patterns, and the preference for more natural structures even among morphomes. The database also allows further explorations of other issues such as the effect of learnability and communicative efficiency on morphological structures, and the lexical and grammatical informativity of morphs and their distribution
