The expedition of Zheng He's fleet to the Western Ocean1 in the first half of the 15th century is an important event in the history of navigation, which has attracted the broad attention of domestic and foreign scholars from different fields2. This paper reveals the relation between Zheng He's voyages and the Asian Monsoon from a geographical perspective. Historical records show that Zheng He's seven voyages to the Western Ocean were precisely organized and successfully carried out due to careful consideration of the conditions and periodical patterns of the Asian tropical and subtropical monsoon. Details such as fleet routes, sailing schedules, wind-waiting points, divergent and rendezvous points were painstakingly planned and arranged in advance by the organizers of the expedition, who all paid close attention to the changing patterns of the Asian Monsoon.

This is a book about the intersection of humor, history, and culture. It explores how film comedy, one of the world’s most popular movie genres, reflects the values and beliefs of those who enjoy its many forms, its most enduring characters and stories, its most entertaining routines and funniest jokes. What people laugh at in Europe, Africa, or the Far East reveals important truths about their differences and common bonds. By investigating their traditions of humor, by paying close attention to the kinds of comedy that cross national boundaries and what gets lost in translation, this study leads us to a deeper understanding of each other and ourselves. Section One begins with a survey of the theories and research that best explain how humor works. It clarifies the varieties of comic forms and styles, identifies the world’s most archetypal figures of fun, and traces the history of mirth from earliest times to today. It also examines the techniques and aesthetics of film comedy: how movies use the world’s rich repertoire of amusing stories, gags, and wit to make us laugh and think. Section Two offers a close look at national and regional trends. It applies the concepts set forth earlier to specific films across a broad spectrum of sub-genres, historical eras, and cultural contexts, providing an insightful comparative study of the world’s great traditions of film comedy.

This chapter examines the work of William Empson, the critic normally assumed to be the least historical in his approach, especially his close attention to ‘the words on the page’. It shows how even his earliest work, such as Seven Types of Ambiguity and Some Versions of Pastoral, is shot through with historical assumptions—indeed, the latter book contains a short history of class relations in England. It moves on to a full-scale discussion of his most daunting work, The Structure of Complex Words, showing the ways in which it is structured by an interpretation of history between the sixteenth and nineteenth centuries, revealing Empson to be a significant historian of English ethical life, who did not share the prevailing declinist or anti-Whig perspective.

Post-traumatic stress disorder (PTSD) is a prevalent mental disorder marked by psychological and behavioral changes. Currently, there is no consensus of preferred antipsychotics to be used for the treatment of PTSD. We aim to discover whether certain antipsychotics have decreased suicide risk in the PTSD population, as these patients may be at higher risk. A total of 38,807 patients were identified with a diagnosis of PTSD through the ICD9 or ICD10 codes from January 2004 to October 2019. An emulation of randomized clinical trials was conducted to compare the outcomes of suicide-related events (SREs) among PTSD patients who ever used one of eight individual antipsychotics after the diagnosis of PTSD. Exclusion criteria included patients with a history of SREs and a previous history of antipsychotic use within one year before enrollment. Eligible individuals were assigned to a treatment group according to the antipsychotic initiated and followed until stopping current treatment, switching to another same class of drugs, death, or loss to follow up. The primary outcome was to identify the frequency of SREs associated with each antipsychotic. SREs were defined as ideation, attempts, and death by suicide. Pooled logistic regression methods with the Firth option were conducted to compare two drugs for their outcomes using SAS version 9.4 (SAS Institute, Cary, NC, USA). The results were adjusted for baseline characteristics and post-baseline, time-varying confounders. A total of 5294 patients were eligible for enrollment with an average follow up of 7.86 months. A total of 157 SREs were recorded throughout this study. Lurasidone showed a statistically significant decrease in SREs when compared head to head to almost all the other antipsychotics: aripiprazole, haloperidol, olanzapine, quetiapine, risperidone, and ziprasidone (p < 0.0001 and false discovery rate-adjusted p value < 0.0004). In addition, olanzapine was associated with higher SREs than quetiapine and risperidone, and ziprasidone was associated with higher SREs than risperidone. The results of this study suggest that certain antipsychotics may put individuals within the PTSD population at an increased risk of SREs, and that careful consideration may need to be taken when prescribed.

AbstractThis research examines the role that fear of sharks has played in the history of St Helena Island Moreton Bay, Queensland through analysis of historical records, newspapers, photographs and literature. The article begins with Aboriginal histories of St Helena Island, colonial settlement of the region and the building of a quarantine station. An exploration of the ways in which settlers’ fear of sharks supported the detention of prisoners in the St Helena Island Penal Establishment follows. The research finds that the warders’ shark-proof swimming enclosure on St Helena Island (1916) records a time when Queensland communities were first seeking to manage the recreational demands of swimmers in the context of a growing public fear of sharks.

AbstractImperfect historical records and complex demographic histories present challenges for reconstructing the history of biological invasions. Here, we combine historical records, extensive worldwide and genome-wide sampling, and demographic analyses to investigate the global invasion of Mimulus guttatus from North America to Europe and the Southwest Pacific. By sampling 521 plants from 158 native and introduced populations genotyped at >44,000 loci, we determined that invasive M. guttatus was first likely introduced to the British Isles from the Aleutian Islands (Alaska), followed by admixture from multiple parts of the native range. We hypothesise that populations in the British Isles then served as a bridgehead for vanguard invasions worldwide. Our results emphasise the highly admixed nature of introduced M. guttatus and demonstrate the potential of introduced populations to serve as sources of secondary admixture, producing novel hybrids. Unravelling the history of biological invasions provides a starting point to understand how invasive populations adapt to novel environments.

The history of navigation and hydrography, as of other crafts or ‘mechanick arts’, has to be constructed from very imperfect materials. Instruments and charts, as the tools of practical men, were commonly discarded when they were worn out or superseded. The high mortality among original charts makes generalization in the comparative history of cartography hazardous. That no Portuguese charts before 1500 are now known does not allow us to conclude that none was made but only that none has survived. Many of the early charts that have been preserved are decorative examples drawn for royal or other patrons; those by which pilots conned their ships had a smaller expectation of life and are correspondingly rare.
