In an effort to fight climate change, many cities try to boost their cycling levels. They often look towards the Dutch for guidance. However, historians have only begun to uncover how and why the Netherlands became the premier cycling country of the world. Why were Dutch cyclists so successful in their fight for a place on the road? Cycling Pathways: The Politics and Governance of Dutch Cycling Infrastructure, 1920-2020 explores the long political struggle that culminated in today’s high cycling levels. Delving into the archives, it uncovers the important role of social movements and shows in detail how these interacted with national, provincial, and urban engineers and policymakers to govern the distribution of road space and construction of cycling infrastructure. It discusses a wide range of topics, ranging from activists to engineering committees, from urban commuters to recreational cyclists and from the early 1900s to today in order to uncover the long and all-but-forgotten history of Dutch cycling governance.

A growing body of scholarship investigates the role of misinformation in shaping the debate on climate change. Our research builds on and extends this literature by 1) developing and validating a comprehensive taxonomy of climate misinformation, 2) conducting the largest content analysis to date on contrarian claims, 3) developing a computational model to accurately detect specific claims, and 4) drawing on an extensive corpus from conservative think-tank (CTTs) websites and contrarian blogs to construct a detailed history of misinformation over the past 20 years. Our study finds that climate misinformation produced by CTTs and contrarian blogs has focused on attacking the integrity of climate science and scientists and, increasingly, has challenged climate policy and renewable energy. We further demonstrate the utility of our approach by exploring the influence of corporate and foundation funding on the production and dissemination of specific contrarian claims.

This chapter provides a review of infectious disease to date and the challenges they may present in the future. The main pandemics that have driven the history of humanity are described, from the first to be recorded in 3180 BC to more recent ones such as AIDIS, SARS and others associated with emerging pathogens. The essential role of emerging scientific specialisms (particularly microbiology, public health and sanitary engineering) to our understanding of the causes of these diseases (and how they may be better monitored, controlled and prevented) is presented. Globalization and climate change, determining factors for the ecology of infectious diseases and their emergence and re-emergence, are discussed and point to the urgent need for research to deal with these threats that continue to have a significant impact on human development and wellbeing.

ABSTRACT The concept of wicked problems can be used as a frame for enriching archivists' understanding of the societal challenges they are confronting in their work. This article explores the core tenets and intellectual history of the concept, looking at the origins of the term; its uses in design, planning, and various policy domains; and recent critiques of the concept. Using examples of archival engagements with the challenges of policing in underserved communities, refugees, child welfare, and climate change, this article examines the role of records and recordkeeping systems in wicked problems and how archivists have used community engagement as a core tenet of how to approach these societal challenges. These engagements also illustrate how grappling with wicked problems can change the practices, theories, and self-awareness of the profession itself.

This book is composed of a set of disparate essays that are grounded in history, political economy, and philosophy. These essays focus on a range of topics addressing different dynamics of the coronavirus pandemic. They include history of pandemics, governmental discourse on health and practical strategies, the role of WHO, neo-liberal economic order and consumerism, social order and human attitudes, nationalism and immigration, and global warming and climate change. Shedding light on these various dynamics, Lal exposes the high claims made by the powerful states like the US, the UK, and European states about their superior political systems, health care programs, and welfare services.

The history of biosystematics research and its impacts on climate goes before political ramifications. Climate change is altering the environments and likely to result in changes in the distribution of species, flowering times; migrate and adapt to the new environmental conditions; or extinction. Adaptive capacity is the ability of the plants to adapt to the impacts of climate change. Adaptation process is going in nature through phenotypic plasticity, natural selection or migration or polyploidization. The options are not mutually exclusive. Phenotypic plasticity may be the most efficient way of adaptation to a new environment. Polyploidization may increase tolerance to diverse ecological conditions and the high incidence of polyploidy in plants indicates its adaptive significance. Population having polyploid pillar complex is a good backup support towards microevolution and speciation, a mode of adaptation. The paper discusses about these biosystematics approaches towards adaptation to new environmental conditions resulting from climate change. It also discusses about the role of taxonomists under the changed circumstances. It is evident from the review that a set of biosystematics data along with other ecological and conservation information needs to be included in Flora and Monographs. It reveals that it was as far as worked out at the Paris Botanical Congress 1954 and put up by Stebbins in a series of proposals, termed as “Stebbins’ Ten Points” that needs further enrichment.

We study the exemplar of the first edition of the «Eneida» (1798) by I. Kotlyarevskyi from the personal library of the famous Slavist Pawel Joseph Šafařik, which is kept in the Dept. of Manuscripts and old prints of the National Museum in Prague Library. The book was offered to P. J. Šafařik by the known Russian and Ukrainian scholar Osyp Bodyanskyi. The influence of «Eneida» on the «Naski Ukrainian Tales» (1835) by O. Bodyanskyi is confirmed by the works of Ivan Franko, where compares the national flavor of both books. We analyse the letters of O. Bodyanskyi to P. Šafařik during 1836–1857 years, published by Leonid Biletskyi (Pragus, 1932) from the archive of P. Šafařik in Prague, as well as the letters of Šafařik to Bodyanskyi during 1838–1857 years, prepared for publication by Petro Lavrov and Mykhaylo Nestorovych Speranskyi (Moscow, 1895). The letter exchange between these scholar-slavists provides grounds for exposing the international and intercultural connections. We define the areas of a common interest of O. Bodyanskyi and P. Šafařik which are: the book exchange, especially the scientific literature on Slavic studies, publishing of Slavic artefacts, providing the information on Ukraine, its language, population, history and literature by O. Bodyanskyi for the «Slavic folk studies» of P. Šafařik. We emphasize on the personal acquaintance of both scholars in Prague in 1837, confirm their contribution in establishing the status of Ukrainian language as an independent one among the other Slavic languages. The also brought into attention the fact that Taras Shevchenko first came across the studies of Šafařik via O. Bodyanskyi, and he regarded the role of the Chech scholar in Slavic revival in the first half of 19ct. We also pay particular attention to the history of the autograph of T. Shevchenko — the beginning of the poem «Ivan Gus» (later, the «Heretic») dedicated to P. Šafařik. This autograph was sent by Vasyl Bilozerskyi to the Narodnyi Dim Library in Lviv in 1863.

This chapter looks at the possible futures associated with climate change, in particular the ecological crisis it will bring for many people around the planet. It does this with a special focus on the political challenges that will accompany this crisis, especially as they relate to democratic politics. It asks how states will manage, and in some cases even survive, in the face of a very serious or catastrophic social-ecological crisis. Toward this end, it examines the long history of a crisis orientation in environmentalism generally, with an emphasis on climate change as the example par excellence. It then examines the worst-case scenarios, including the concept of “fortress world.” It concludes with a discussion of environmental security, the role of the military during the crisis, and the politics of “survivalism.”
