A model is developed for evaluating the conditional probability of hitting an upper barrier before a lower barrier, and vice versa, for a tied down geometric Brownian motion with drift. The method produces an analytical value for this probability, assuming that the barrier levels are constant and continuously monitored.

Abstract

Entrepreneurs are the moving force of economic growth. Through entrepreneurship comes employment opportunities. From the Filipino youth to Filipino women and up to Filipino professional, there is always that profound intention to engage themselves in entrepreneurship not just to generate revenue but also to help in the upliftment of…[Read more]

Korean War Battle of Chosin Reservoir: The British casualties in one day in the battle of the Somme during WWI were 50,000 dead and wounded. 50,000 casualties in one day – patriotism & esprit de corps – is a very solid proof that there is a “psychology of groups.”
Why is the Battle of Chosin Reservoir important?
Preface: Materialist dogma – “…[Read more]

Lukács is widely recognized as being the first critical theorist to have explicitly developed the idea of a “standpoint theory”. According to such a theory, members of oppressed groups enjoy an epistemic privilege regarding the nature of their oppression. However, there is no agreement regarding what precise argument Lukács offers for his claim…[Read more]

आज तकनीक पर कामचलताऊ ढ़ंग से लिखने-बोलने से से काम नहीं चलेगा, जैसा कि हिंदी बुद्धिजीवी अभी कर रहे हैं। बल्कि इस बारे में हल्की-फुल्की भाषा में सामग्री पढ़ने की चाह रखने से भी बाज आना चाहिए। चलताऊ भाषा में आप नए उपकरणों की गुणवत्ता की, उनके उपयोग आदि की जानकारी ले-दे सकते हैं। किसी स्मार्ट उपकरण समीक्षाएं पढ़कर उसे खरीदने या न खरीदने का फैसला कर…[Read more]

Citizenship and the posthuman have not been often theorized together. In this paper, I want to think about their coalition both as a new episode in the efforts of politics for citizenship, including knowledge politics, and as a source of rebalancing power against governmental and corporate interests in citizenship politics. Here, I seek to address…[Read more]

South African universities’ use of digital technologies in learning has increased in recent years. Given that
social exposure, the context and pedagogic uses of technology influence learning expectations and
learner involvement, it is important to understand students’ experiences of the use of different
technological tools. This article emp…[Read more]

Globally, student support mechanisms focus almost exclusively on academically ‘under-performing’
students, especially as insofar as academic development practices are concerned. This article makes a
case for a shift in approach. Using the context of one country, South Africa, we sought to better
understand the strengths that academically…[Read more]

Pre-service mathematics teachers’ (PMTs) subject competency continues to engage scholars and researchers.
Understanding level of knowledge of concepts that PMTs bring to their learning in university is crucial to
developing their teacher knowledge. This article examines genetic decomposition of schemas PMTs in one
university in South Africa b…[Read more]

This article presents a model for pricing complex CDO structures and compute the sensitivities of the risk factors. The complex CDO structures need to be priced using the market information on tranche losses at multiple points of time. Currently, the model is being used for the valuation of forward starting CDO trades (FSCDO) and loss-trigger…[Read more]

The structure of a Binary Return Note is similar to the one of a regular note, but the coupons are
contingent on return rates on stocks. Quasi-Monte Carlo simulation is used for pricing the product.

We present a pricing model for fade option. A fade option can be more precisely named as “point-barrier option”. The fade option is a vanilla option that exists or dies if a barrier is breached on a single preset date, which is prior or equal to the contract maturity.

Average rate or Asian options have a payoff function proportional to an average rate or price. The average price is calculated over a sampling of specified dates that need not be equally spaced in time. The average price or rate tends to be less volatile than a single underlying price and hence, an option on the underlying average price should be…[Read more]

A high percentage of theatrical prints and manuscripts from the aurisecular period have never been transcribed in an analogical or, of course, digital format. It is therefore impossible to use these documents to carry out searches of our interest or for the valuable computer analyses (stylometry, topic modelling, sentiment analysis, etc.) that…[Read more]

TEXORO: Textos del Siglo de Oro es una herramienta desarrollada por Álvaro Cuéllar y Germán Vega que permite realizar búsquedas en un amplio corpus de teatro del Siglo de Oro. Es nuestra intención que un futuro crezca ofreciendo otros tipos de textos fuera del ámbito teatral.

El proyecto ETSO: Estilometría aplicada al Teatro del Siglo de Oro surge del interés del investigador Álvaro Cuéllar y del catedrático Germán Vega García-Luengos en aplicar las nuevas herramientas informáticas a los numerosos problemas de autoría que presenta el teatro del Siglo de Oro español. Este portal trata de ofrecer análisis que puedan arr…[Read more]

Finding the accurate date of texts is one of the most puzzling challenges in the study of Spanish aurisecular theater. Stylometry, the computer technique centered on the comparison of texts based on their writing, which has been successfully used in recent years to solve authorship questions, can also serve to shed light on this issue. In this…[Read more]
