For almost 20 years after the end of World War II, many Japanese women were challenged by a dark secondary hyper pigmentation on their faces. The causation of this condition was unknown and incurable at the time. However this symptom became curable after a number of new cosmetic allergens were discovered through patch tests and as an aftermath, various cosmetics and soaps that eliminated all these allergens were put into production to be used exclusively for these patients. An international research project conducted by seven countries was set out to find out the new allergens and discover non-allergic cosmetic materials. Due to these efforts, two disastrous cosmetic primary sensitizers were banned and this helped to decrease allergic cosmetic dermatitis. Towards the end of the 20th century, the rate of positives among cosmetic sensitizers decreased to levels of 5% - 8% and have since maintained its rates into the 21th century. Currently, metal ions such as the likes of nickel have been identified as being the most common allergens found in cosmetics and cosmetic instruments. They often produce rosacea-like facial dermatitis and therefore allergen controlled soaps and cosmetics have been proved to be useful in recovering normal skin conditions.

Since the beginning of the last decade of the past 20th century, Bulgaria has entered a new, complex stage of its development, with many reforms. Education and teacher training reforms are influenced by the global and European trends, as well as by the national changes (political, economical, social, and technological). The author analyses the main characteristics of the changed teacher training system and teacher qualification and development system. Some of the challenges and directions of the transformation and future development of the teacher education and qualification in Bulgaria are discussed.

This review article engages with a rich field of scholarship on logistics that has gathered momentum over the past decade, focusing on two new publications by Laleh Khalili and Martín Arboleda. It contextualizes how and why logistics is bound up with the militarization of contemporary political and social life. I argue that the later 20th century rise of logistics can be better understood as both a response to and symptom of capitalist crisis and I situate this scholarship on war and logistics in relationship to Giovanni Arrighi’s account of crisis and ‘unravelling hegemony’. I also show how logistics provides essential critical and visual resources that contribute to efforts to map global capitalism and to debates on totality and class composition in contemporary critical theory. Finally, contemporary events such as the ongoing Coronavirus crisis and the reemergence of Black Lives Matter are considered in light of this analysis with reference to the centrality of logistics to racial capitalism.

Historical Reconstructions

AbstractThe historical evolution of Earth’s energy imbalance can be quantified by changes in the global ocean heat content. However, historical reconstructions of ocean heat content often neglect a large volume of the deep ocean, due to sparse observations of ocean temperatures below 2000 m. Here, we provide a global reconstruction of historical changes in full-depth ocean heat content based on interpolated subsurface temperature data using an autoregressive artificial neural network, providing estimates of total ocean warming for the period 1946-2019. We find that cooling of the deep ocean and a small heat gain in the upper ocean led to no robust trend in global ocean heat content from 1960-1990, implying a roughly balanced Earth energy budget within −0.16 to 0.06 W m−2 over most of the latter half of the 20th century. However, the past three decades have seen a rapid acceleration in ocean warming, with the entire ocean warming from top to bottom at a rate of 0.63 ± 0.13 W m−2. These results suggest a delayed onset of a positive Earth energy imbalance relative to previous estimates, although large uncertainties remain.

A dictionary born old. Legitimization and delegitimization of the Second Spanish Republic. The controversy following the recent publication of the Spanish Biographical Dictionary by the Real Academia de la Historia is here analysed. Many entries about the 20th century in Spain highlight the questionable aspects of a cultural project that derives from a public usage typical of the past concerning the legitimization and delegitimization of the Second Spanish Republic.

Over the past 75 years, the higher-level taxonomy of bivalves has received less attention than that of their fellow molluscs, gastropods. The publication of the bivalve volumes of the Treatise on Invertebrate Paleontology in 1969 was not followed by an explosion of study into the evolution of bivalves; rather, with only one or two exceptions, bivalve workers were noticeably absent from the cladistic and molecular revolutions that were taking place during the 1970s and 1980s, even as gastropods received considerable attention. Over the past ten years, cladistics and molecular systematics have begun to be applied to solve problems of bivalve evolutionary biology. These studies, most of which have been undertaken by paleontologists, have halted the stagnation in bivalve systematics. Bivalve systematics looks to have an exciting future, as the excellent fossil record of the Bivalvia will be used in conjunction with cladistics and molecular systematics to solve problems in not just bivalve evolution but evolutionary biology in general.

The possible ways that information can be represented mentally have been discussed often over the past thousand years. However, this issue could not be addressed rigorously until late in the 20th century. Initial empirical findings spurred a debate about the heterogeneity of mental representation: Is all information stored in propositional, language-like, symbolic internal representations, or can humans use at least two different types of representations (and possibly many more)? Here, in historical context, we describe recent evidence that humans do not always rely on propositional internal representations but, instead, can also rely on at least one other format: depictive representation. We propose that the debate should now move on to characterizing all of the different forms of human mental representation.

Abstract. Recent studies demonstrate that the Hadley Circulation has intensified and expanded for the past three decades, which has important implications for subtropical societies and may lead to profound changes in global climate. However, the robustness of this intensification and expansion that should be considered when interpreting long-term changes of the Hadley Circulation is still a matter of debate. It also remains largely unknown how the Hadley Circulation has evolved over longer periods. Here, we present long-term variability of the Hadley Circulation using the 20th Century Reanalysis. It shows a slight strengthening and widening of the Hadley Circulation since the late 1970s, which is not inconsistent with recent assessments. However, over centennial timescales (1871–2008), the Hadley Circulation shows a tendency towards a more intense and narrower state. More importantly, the width of the Hadley Circulation might have not yet completed a life-cycle since 1871. The strength and width of the Hadley Circulation during the late 19th to early 20th century show strong natural variability, exceeding variability that coincides with global warming in recent decades. These findings raise the question of whether the recent change in the Hadley Circulation is primarily attributed to greenhouse warming or to a long-period oscillation of the Hadley Circulation – substantially longer than that observed in previous studies.

Risk of infection remains a major concern for surgeons. The expansion of surgery towards the end of the 19th century determined a noticeable increase in septicemia and gangrene, and surgeons developed various techniques to limit them. In a previous publication, we reminded our readers of one of the gems of Italian surgery, Dr. Giuseppe Ruggi, who operated in Bologna from the end of 19th to the beginning of the 20th century. To him we owe the introduction and dissemination of the antiseptic method in Bologna. His scientific activity continued with Dr. Benedetto Schiassi, his successor. The techniques used to avoid microbial contamination by the Italian surgeon Dr. Schiassi, are particularly interesting, as Schiassi’s tentorium is still useful. Despite advances in surgical technologies, many innovations to prevent infection in surgery proposed in the past are still relevant today.
