AbstractThis paper, relying on a still relatively unexplored long-term dataset on U.S. patenting activity, provides empirical evidence on the history of labor-saving innovations back to early nineteenth century. The identification of mechanization/automation heuristics, retrieved via textual content analysis on current robotic technologies by Montobbio et al. (Robots and the origin of their labour-saving impact, LEM Working Paper Series 2020/03), allows to focus on a limited set of CPC codes where mechanization and automation technologies are more prevalent. We track their time evolution, clustering, eventual emergence of wavy behavior, and their comovements with long-term GDP growth. Our results challenge both the general-purpose technology approach and the strict 50-year Kondratiev cycle, while they provide evidence of the emergence of erratic constellations of heterogeneous technological artefacts, in line with the development-block approach enabled by autocatalytic systems.

This paper examines how the past of desert landscapes has been interpreted since European explorers and scientists first encountered them. It charts the research that created the conceptual space within which archaeologists and Quaternarists now work. Studies from the 1840s–1960s created the notion of a ‘Great Australian Arid Period'. The 1960s studies of Lake Mungo and the Willandra Lakes by Jim Bowler revealed the cyclical nature of palaeolakes, that changed with climate changes in the Pleistocene, and the complexity of desert pasts. SLEADS and other researchers in the 1980s used thermoluminescence techniques that showed further complexities in desert lands beyond the Willandra particularly through new studies in the Strzelecki and Simpson Dunefields, Lake Eyre, Lake Woods and Lake Gregory. Australian deserts are varied and have very different histories. Far from ‘timeless lands', they have carried detailed information about long-term climate changes on continental scales.

Electronic theses and dissertations (ETDs) have been a recent addition to the library's online access system, or digital project. This chapter traces the history of dissertations, from their printed form and issuance in microform by various agencies. It examines the changes in textual content and its presentation from the pre-digital to digitized documents, and the relation to software developed for music and other fields. It then examines the evolution of audio and video formats for the accompanying materials, particularly in the performing arts, and the content of these materials. It concludes with issues in ETDs management and ensuring long-term access and preservation, such as digital quality and copyright.

In early 2018, the Polish parliament adopted controversial legislation criminalising assertions regarding the complicity of the ‘Polish Nation’ and the ‘Polish State’ in the Holocaust. The so-called Polish Holocaust Law provoked not only a heated debate in Poland, but also serious international tensions. As a result, it was amended only five months after its adoption. The reason why it is worth taking a closer look at the socio-cultural foundations and political functions of the short-lived legislation is twofold. Empirically, the short history of the Law reveals a great deal about the long-term role of Jews in the Polish collective memory as an unmatched Significant Other. Conceptually, the short life of the Law, along with its afterlife, helps capture poll-driven, manifestly moralistic and anti-pluralist imaginings of the past, which I refer to as ‘mnemonic populism’. By exploring the relationship between popular and political images of the past in contemporary Poland, this article argues for joining memory and populism studies in order to better understand what can happen to history in illiberal surroundings.

On 1 July 1981 the Chinese Communist Party celebrated the sixtieth anniversary of its foundation. To mark this occasion, the Party itself issued a statement summing up the experience of recent decades. It seems an appropriate time for outsiders as well to look back over the history of the past 60 years, in the hope of grasping long-term tendencies which may continue to influence events in the future.

This study explores the history of the development of Sphagnum communities in an ombrotrophic peatland – Bagno Kusowo – over the past 650 years, based on high-resolution plant macrofossil and testate amoebae analysis. Our research provided information related to the length of peatland existence and the characteristics of its natural/pristine state before the most recent human impacts. Changes in the Sphagnum communities before human impact could have resulted from climate cooling during the ‘Little Ice Age’ (LIA). In this cold and unstable hydrological period, among vascular plants, Eriophorum vaginatum and Baeothryon caespitosum dominated in the peatland vegetation. Peat-forming Sphagnum communities survived the drainage conducted during the 20th century at the Bagno Kusowo bog. We provide three important messages through this study: (1) testate amoebae reflect similar hydrological trends in two peat cores despite considerable microhabitat variability, (2) average long-term water level 10 cm below the surface should be a target for active bog conservation and (3) sites like Bagno Kusowo are extremely important to preserve the remains of pristine biodiversity (including genetic diversity of plants and protists) that was completely removed from most of the raised bogs in Europe due to human activities, for example, drainage.

The history of spruce budworm (Choristoneurafumiferana (Clem.)) outbreaks for the past 200 to 300 years, for nine regions in eastern Canada, indicates that outbreaks have occurred more frequently in the 20th century than previously. Regionally, 21 outbreaks took place in the past 80 years compared with 9 in the preceding 100 years. Earlier infestations were restricted to specific regions, but in the 20th century they have coalesced and increased in size, the outbreaks of 1910, 1940, and 1970 having covered 10, 25, and 55 million ha respectively. Reasons for the increase in frequency, extent, and severity of outbreaks appear mostly attributable to changes caused by man, in the forest ecosystem. Clear-cutting of pulpwood stands, fire protection, and use of pesticides against budworm favor fir–spruce stands, rendering the forest more prone to budworm attack. The manner and degree to which each of these practices has altered forest composition is discussed. In the future, most of these practices are expected to continue and their effects could intensify, especially in regions of recent application. Other practices, including large-scale planting of white spruce, could further increase the susceptibility of forest stands. Forest management, aimed at reducing the occurrence of extensive fir–spruce stands, has been advocated as a long-term solution to the budworm problem. The implementation of this measure at a time when man's actions result in the proliferation of fir presents a most serious challenge to forest managers.

Drawing on long-term ethnographic research in the Blue Nile town of Sennar, supported by archival and historical documentation, this article explores the history of Zar spirit possession in Sudan, and the light this throws on the interplay of religions over the past 150 years. Life history data supports the argument that contemporary Zar is grounded in forms and rituals derived from the ranks of the ninteenth-century Ottoman army, and these remain the basis of ritual events, even as they accommodate ongoing changes in this part of Africa. Many of these changes are linked to the dynamic interplay of Zar with forms of Islam, on the one hand, and Christianity, on the other. In the former colonial periods, political power resided with the British, and Khawaja (European) Christian Zar spirits are remembered as far more important. Today that authority in Zar has shifted to spirits of foreign Muslims and local holy men, on the one hand, and to subaltern Blacks, on the other. These speak to concerns of new generations of adepts even as changes in the larger political and religious landscapes continue to transform the context of Zar.

Over the past decade, in Russian Federation there has been a steady increase in the incidence of MAC-infection in patients with HIV (the growth of nosology over the past five years, on average, was 57% per year). This determines the interest in this problem, especially in terms of the high inefficiency of treatment for the disease, the long term and cost of treatment. The history of the study of Mycobacterium Avium Complex-infection (MAC) originates in the early eighties in the United States, when the prognosis for a patient with AIDS and mycobacteriosis was extremely poor: mortality within one year after the detection of pathogen reached 71%. The role of infection in the thanatogenesis of patients was, however, established only by the beginning of the nineties. The detection of macrolide activity against the pathogen significantly improved the prognosis for patients, especially in combination with highly active antiretroviral therapy. The widespread introduction of antiviral drugs into practice and the ability to achieve immune reconstitution prevented the development of opportunistic infections, but did not solve the remaining issues of the treatment of the MAC-infection. The main one is the treatment of patients with a clarithromycin-resistant pathogen. There is no consensus on the sensitivity of non-tuberculous mycobacteria to antibacterials.

This paper traces the history of local government in England (as opposed to the United Kingdom) since the early nineteenth century, and explores five long-term trends in its evolution. These are path dependence; the occurrence of major structural change; the phenomenon of policy reversal; the treatment of urban areas; and resistance to regional government. The author concludes that throughout the period under study, policy towards local government has exhibited a ‘pendulum effect’, with two opposing emphases operating in a sequential, rather than a simultaneous manner.
