Beyond the texts on women’s medicine associated with the name of a 12th-century female medical practitioner from Salerno named Trota (or the title, “Trotula”), the most widely circulated texts were those deriving from the ancient Greek *Gynecology* of Soranus (2nd century CE). In particular, the Latin translation/adaptation by Muscio (or Mustio),…[Read more]

As practitioners and scholars who engage with music encoding we already understand the affordances that encoding music or text can bring to our research and scholarship. However, individuals who are not yet familiar with encoding schemas and the usefulness of digital methodologies may not have a clear understanding of the “why” in using a dig…[Read more]

The article presents a model for pricing digital-type barrier options on baskets of equity stocks. Within each payment period, there is a series of basket observation times. If at each observation time we observe that all basket constituent stocks remain between their lower and upper barriers, we receive a fixed coupon amount on the payment date…[Read more]

Este artículo visibiliza el uso que se le puede dar a una serie de proyectos de Humanidades Digitales, como son las bases de datos de Rolecall, DICAT y CATCOM o la biblioteca digital EMOTHE, a la hora de analizar las dinámicas escenográficas en el teatro español de finales del siglo XVI y principios del siglo XVII, coincidiendo con las déc…[Read more]

We present a model for pricing an exotic swap where one party receives a fixed amount and makes a series of variable payments at the end of each pre-defined calculation period. The variable payments can be modeled as Asian put option payoffs on the weighted sum of two respective commodity basket levels. Furthermore, each basket level consists of a…[Read more]

This document lays out a series of points in regard to a recently posted pre-print on the history of plague in late medieval and early modern Europe: Marcel Keller et al., “A Refined Phylochronology of the Second Plague Pandemic in Western Eurasia.” I am a historian of medicine and I am presenting these as historical questions. I have written it…[Read more]

A model is present for pricing an Equity Asian Swap. One leg of the swap pays the return from a monthly average of the S&P TSE60 index less a constant strike. The payment from the other leg is similarly defined for a stock. The payments are tied to notional amounts that are specified according to two pre-determined monthly schedules. Most of the…[Read more]

A variance/volatility swap is an instrument that allows explicit exposure to the realized variance/volatility of an index, stock, etc., without exposure to other risks commonly encountered with derivatives: delta, gamma, etc.

We review the equity forward and futures pricing models. Consider an index level, I, at a future time, T. With respect to I, we calculate 1) the forward price, 2) the futures price, and 3) delta.

A valuation model is presented to calculate price, hedge ratio, and implied volatility for forward starting European calls and puts. The model focuses on the numerical accuracy of the implementation.

Despite the epistemological importance of the scholarly journal, few thorough histories of individual academic journals have been written, especially of journals in the arts and humanities. This article uses both archival material and oral histories to construct a multifaceted history of Leeds Studies in English (LSE) from the beginning of its…[Read more]

The model calculates numbers that characterize the effect of adding an extra instrument to a portfolio of loan commitments. To be useful, these numbers should be additive with respect to the facilities making up the portfolio, so that their total would have the same meaning for the portfolio as each individual number has for the respective…[Read more]

When considering the establishment of overseas viking encampments, some of the most detailed and vivid contemporary descriptions of this activity originate from the Frankish realm, a region which nevertheless remains precariously positioned in wider comparative investigations of the viking world. To address this imbalance, this chapter assembles…[Read more]
