Abstract:
<p><strong>Abstract.</strong> This paper reports the results of an experiment that aims at the virtual reconstruction of a urban site that has been partially reshaped during the 20th century; the reconstruction process is based on period photos. The chosen case study is the eldest harbour of Palermo, named ‘Cala’; the site was bombed during World War II and new buildings took the place of the ruined ones. Two period photos, taken from an aircraft, document the buildings that were destroyed by bombs.</p><p> The 3D restitution process used the ‘inverse’ projection from period photos (2D) to the virtual space (3D) ; the first step was therefore addressed to the calculation of the inner parameters (focal length, principal point coordinates) and of the cameras’ pose, i.e. their position and orientation. The data needed for these calculations were extracted from the 3D laser scanning survey of those buildings that appear in photos and that are still on site. The calculation of inner parameters and poses has been computed with a motion tracking commercial package.</p><p> The second part of the paper focuses a process for the fruition of virtual reconstructions, based on the alignment of real panoramic images, generated by photos taken on site, and of virtual panoramic images, extracted from the 3D reconstruction model; the proposed method uses SfM photogrammetric tools.</p>

Abstract:
This paper assesses the prospects of a 2021 "time bomb" in small-and medium-sized enterprise (SME) failures triggered by the generous support policies enacted during the 2020 COVID-19 crisis. Policies implemented in 2020 do not on their own create a 2021 time bomb for SMEs. Rather, business failures and policy costs remain modest. By contrast, credit contraction poses significant risk. Such a contraction would disproportionately impact firms that could survive COVID-19 in 2020 without any fiscal support. Even in that scenario, most business failures would arise not from excessively generous 2020 policies but rather from the contraction of credit to the corporate sector.

Abstract:
SUMMARYMany pollinators are currently suffering from declines, diminishing their gene pool and increasing their vulnerability to parasites. Recently, an increasing diversity of parasites has been recorded in bumblebees, yet for many, knowledge of their virulence and hence the risk their presence poses, is lacking. The deformed wing virus (DWV), known to be ubiquitous in honey bees, has now been detected in bumblebees. In addition, the neogregarineApicystis bombihas been discovered to be more prevalent than previously thought. Here, we assess for the first time the lethal and sublethal effects of these parasites during single and mixed infections of worker bumblebees (Bombus terrestris). Fifteen days after experimental exposure, 22% of bees exposed toA. bombi, 50% of bees exposed to DWV and 86% of bees exposed to both parasites had died. Bumblebees that had ingestedA. bombihad increased sucrose sensitivity (SS) and a lower lipid:body size ratio than control bees. While dual infected bumblebees showed no increase in SS. Overall, we find thatA. bombiexhibits both lethal and sublethal effects. DWV causes lethal effect and may reduce the sub lethal effects imposed byA. bombi. The results show that both parasites have significant, negative effects on bumblebee health, making them potentially of conservation concern.

Abstract:
Steve Fuller's article on the events of September 11th raises a number of important questions about the role of sociology in public discussion and debate. This brief response, in taking up this challenge, focuses on the issue of bio-terrorism. In doing so, a balance sheet is provided of the potential threat this poses, drawing both on the history of biological and chemical weapons to date, and the potential epidemics of fear they unleash in the aftermath of September 11th. Medical sociology, it is argued, alongside the sociology of emotions, is particularly well placed to address such issues, including questions of the biological and broader themes of war and health, medicine and the military.

Abstract:
Japan is sitting on a demographic time bomb. The declining birth rate because of changing societal and economic factors impacting on priorities in human lives, and accentuated by a rapidly growing population poses a new challenge to policy makers. The governmental responses have been inadequate and need to be seriously addressed in the interests of the future of the country. Other Asian countries in the path of modernisation and fast economic growth are also falling into such trap. Like in the economic development Japan was the leader that led to the faster growth in other Asian countries, Japan ought to emerge as the new leader in addressing this demographic challenge so that other Asian countries could emulate Japan’s example.

Abstract:
The article describes the effects of unexploded ordnance, known as UXO, on food production and farming culture in Laos. Between 1964 and 1973 the United States flew more than 580,000 bombing missions over Laos, and an estimated 30 percent of all munitions dropped did not explode as designed. Millions of those unexploded bombs remain in the ground today. UXO poses daily risks to life and limb for the Laotian population, particularly Laotian farmers and rural residents. The story is told through photos, individual interviews and first-hand reporting along The Ho Chi Minh Trail, in Phonsavanh (also known as Phonsavan) town, in Xiengkhouang (also known as Xiangkhoang and Xiangkhouang) Province and in Phongsali Province. Special emphasis is placed on the continuing danger of decades-old cluster munitions, also known as “bombies.” Traditional Laotian foods laap, or lam, and sticky rice are also noted.

Abstract:
The earliest years of photography were full of experimentation and innovation; many photographers from this era carefully documented their experimental procedures. Consequently, it is possible to reproduce historically accurate photographs and negatives today. One of the oldest forms of photographic technology is the waxed paper negative, popular during the mid-19th century. It consists of a photosensitive sheet of writing paper coated with a layer of wax to render it transparent. Modern waxed paper negatives made using 19th century paper can potentially pass for historically significant 19th century negatives. This poses problems to museums and others interested in studying or collecting authentic 19th century photographic images. We have developed methods for separating the organic components of waxed paper negatives and measuring their radiocarbon content as a means of distinguishing between modern and historic waxed paper negatives. By detecting the presence or lack of bomb carbon in a given negative, this process can act as a tool for authentication. We have mainly focused on the extraction and 14C measurement of the wax component, reasoning that modern photographers might have easy access to 19th century paper, but would less likely use 19th century beeswax.

Abstract:
Peaceful nuclear cooperation—the transfer of nuclear technology, materials, or know-how from one state to another for peaceful purposes—leads to the spread of nuclear weapons. In particular, countries that receive peaceful nuclear assistance are more likely to initiate weapons programs and successfully develop the bomb, especially when they are also faced with security threats. Statistical analysis based on a new data set of more than 2,000 bilateral civilian nuclear cooperation agreements signed from 1950 to 2000 lends strong support for this argument. Brief case studies of the Indian and Pakistani nuclear weapons programs provide further evidence of the links between peaceful nuclear assistance and proliferation. The finding that supplier countries inadvertently raise the risks of nuclear proliferation poses challenges to the conventional wisdom. Indeed, the relationship between civilian nuclear cooperation and proliferation is surprisingly broad. Even assistance that is often viewed as innocuous, such as training nuclear scientists or providing research or power reactors, increases the likelihood that nuclear weapons will spread. “Proliferation-proof” nuclear assistance does not exist. With a renaissance in nuclear power on the horizon, major suppliers, including the United States, should reconsider their willingness to assist other countries in developing peaceful nuclear programs.

Abstract:
AbstractSpeleothem organic matter can be a powerful tracer for past environmental conditions and karst processes. Carbon isotope measurements (δ13C and 14C) in particular can provide crucial information on the provenance and age of speleothem organic matter, but are challenging due to low concentrations of organic matter in stalagmites. Here, we present a method development study on extraction and isotopic characterization of speleothem organic matter using a rapid procedure with low laboratory contamination risk. An extensive blank assessment allowed us to quantify possible sources of contamination through the entire method. Although blank contamination is consistently low (1.7 ± 0.34 – 4.3 ± 0.86 μg C for the entire procedure), incomplete sample decarbonation poses a still unresolved problem of the method, but can be detected when considering both δ13C and 14C values. We test the method on five stalagmites, showing reproducible results on samples as small as 7 μg C for δ13C and 20 μg C for 14C. Furthermore, we find consistently lower non-purgeable organic carbon (NPOC) 14C values compared to the carbonate 14C over the bomb spike interval in two stalagmites from Yok Balum Cave, Belize, suggesting overprint of a pre-aged or even fossil source of carbon on the organic fraction incorporated by these stalagmites.

Abstract:
This introductory chapter provides some background into the events leading up to President Harry S. Truman's intent to develop a hydrogen bomb, otherwise known as the “Super.” The short interval between the surprise Soviet atomic test in late summer 1949 and the presidential decision of January 1950, coupled with the strictly limited cast of individuals who played a part in it, poses the question of why Truman acted as he did. There are few clear answers to be found in the vast body of Truman scholarship or in the president's memoirs, which pass lightly over the decision. Truman, wedded to the idea of U.S. nuclear superiority as a guarantor of peace, paid little regard to the phenomenal increase in the destructive power of the hydrogen bomb. He saw it as no more than a qualitative enhancement of what was already in the armory.

Abstract:
The growing number of terrorist attacks in the past decade has focused the public’s attention on the severity of such a man–made hazard. The rising threat of improvised explosive devices — one of the most successful attack strategies — has significantly increased the number of threats on the ground, in the form of suicide–bombs, vehicle–bombs, etc., thereby requiring the development of more effective blast risk mitigation measures. However, the modern proliferation of such measures poses the problem of evaluating their cost–effectiveness, which prompts the need for a comprehensive optimization methodology — capable of maximizing the resilience of the built environment. The aim of this paper is to lay out the foundations of a resilience–based framework for quantifying the performance of different infrastructure elements incurring blast threats, by means of functionality and resilience indicators. The proposed framework can quantify the consequences of multiple outdoor explosions typified by the emblematic car–bomb scenario. The level of localized damage is evaluated via pressure–impulse diagrams; local failures are then aggregated into the definition of resilience and functionality indicators, designed to provide the analyst with a comprehensive picture of global damage, residual functionality, and downtime of the structural system.
