Abstract Modern Chinese took the place of classical Chinese and has been the standard form of writing since the early 1920s. While several studies have been carried out on diachronic variation in modern written Chinese, these include few aggregate investigations. This study examines the diachronic variation in modern Chinese writings and translations from the 1900s to the 2000s. Frequencies of multiple linguistic features sensitive to historical change were drawn from a multi-genre comparable corpus, ‘DCMCWT’, containing five periods: 1900–1911, 1919–1930, 1931–1949, 1950–1966, and 1978–2012. Hierarchical agglomerative clustering was employed for periodisation, while multidimensional scaling supplemented the developmental path. The results suggest that Chinese writings and translations fall into three broad periods: 1900–1911, 1919–1966, and 1978–2012. Chinese translations follow a similar evolutionary path as the writings, and the gap between them, narrowed from 1900 to 2012. This developmental path corresponds to the socio-historical backgrounds in Chinese history and shares similarities and differences with the development of English. Diachronic variation in early modern Chinese mirrors that of English in that both languages developed to be more colloquial and interactive. However, early modern Chinese is different from English, as diglossia has played a crucial evolutionary role.

Target Set

The scientific community is active in developing new models and methods to help reach the ambitious target set by UN SDGs7: universal access to electricity by 2030. Efficient planning of distribution networks is a complex and multivariate task, which is usually split into multiple subproblems to reduce the number of variables. The present work addresses the problem of optimal secondary substation siting, by means of different clustering techniques. In contrast with the majority of approaches found in the literature, which are devoted to the planning of MV grids in already electrified urban areas, this work focuses on greenfield planning in rural areas. K-means algorithm, hierarchical agglomerative clustering, and a method based on optimal weighted tree partitioning are adapted to the problem and run on two real case studies, with different population densities. The algorithms are compared in terms of different indicators useful to assess the feasibility of the solutions found. The algorithms have proven to be effective in addressing some of the crucial aspects of substations siting and to constitute relevant improvements to the classic K-means approach found in the literature. However, it is found that it is very challenging to conjugate an acceptable geographical span of the area served by a single substation with a substation power high enough to justify the installation when the load density is very low. In other words, well known standards adopted in industrialized countries do not fit with developing countries’ requirements.

Abstract The study of pre-modern Chinese hegemony is crucial for both theorizing hegemony and envisioning a new global order. I argue the pre-modern Chinese hegemony was a reciprocal rule of virtue, or aretocracy, driven by the transnational sociocultural elites shi. In contrast to the prevailing models of Chinese hegemony, the Early Modern East Asia was not dominated by the unilateral normative influence of the Chinese state. The Chinese and non-Chinese shi as non-statist sociocultural elites co-produced, through their shared civilizational heritage, a hegemonic order in which they had to show excellence in civil virtues to wield legitimate authority. In particular, the Ming and Chosŏn shi developed a tradition of envoy poetry exchanges as a medium for co-constructing Chinese hegemony as aretocracy. The remarkable role of excellent ethos for world order making in Early Modern East Asia compels us to re-imagine how we conduct our global governance.

AbstractCOVID-19-associated respiratory failure offers the unprecedented opportunity to evaluate the differential host response to a uniform pathogenic insult. Understanding whether there are distinct subphenotypes of severe COVID-19 may offer insight into its pathophysiology. Sequential Organ Failure Assessment (SOFA) score is an objective and comprehensive measurement that measures dysfunction severity of six organ systems, i.e., cardiovascular, central nervous system, coagulation, liver, renal, and respiration. Our aim was to identify and characterize distinct subphenotypes of COVID-19 critical illness defined by the post-intubation trajectory of SOFA score. Intubated COVID-19 patients at two hospitals in New York city were leveraged as development and validation cohorts. Patients were grouped into mild, intermediate, and severe strata by their baseline post-intubation SOFA. Hierarchical agglomerative clustering was performed within each stratum to detect subphenotypes based on similarities amongst SOFA score trajectories evaluated by Dynamic Time Warping. Distinct worsening and recovering subphenotypes were identified within each stratum, which had distinct 7-day post-intubation SOFA progression trends. Patients in the worsening suphenotypes had a higher mortality than those in the recovering subphenotypes within each stratum (mild stratum, 29.7% vs. 10.3%, p = 0.033; intermediate stratum, 29.3% vs. 8.0%, p = 0.002; severe stratum, 53.7% vs. 22.2%, p < 0.001). Pathophysiologic biomarkers associated with progression were distinct at each stratum, including findings suggestive of inflammation in low baseline severity of illness versus hemophagocytic lymphohistiocytosis in higher baseline severity of illness. The findings suggest that there are clear worsening and recovering subphenotypes of COVID-19 respiratory failure after intubation, which are more predictive of outcomes than baseline severity of illness. Distinct progression biomarkers at differential baseline severity of illness suggests a heterogeneous pathobiology in the progression of COVID-19 respiratory failure.

Abstract This paper presents a diachronic study of Modern Hebrew agreement between numerals and their quantified nouns. This research is possible thanks to the discovery of two rare collections of recordings from the 1950s and 1960s, which document four generations of speakers and have become important sources of spoken Early Modern Hebrew. On the basis of these two corpora, I compare numeral agreement in the first two generations of speakers with present-day usage and analyze trends of change and conversation in Modern Hebrew. The study shows that the first generation of speakers (“Gen1”) largely acquired the gender distinction of cardinals. However, in contrast to other agreement issues that educated Gen1 speakers realized fully, numeral use showed variation and absence of agreement in a small set of cases. Moreover, some linguistic features of Gen1 Hebrew found in this study no longer characterize Present-Day Hebrew; among these features is prosodic conditioning, which led to a Gen1 tendency to use the feminine form of the numeral ‘four’ with masculine nouns more frequently than was the case with other numerals.

Some time ago the Commonwealth and Overseas History Society of Cambridge University asked me to provide an overview of recent scholarship on modern Chinese history. What follows is a written version of this ‘public service’ lecture aimed at non-specialist historians. It discusses Western scholarship on China from the eighteenth until the twentieth century.
