Translating Khan on Singer: Global Solvent Versus Local Interpretation

This work focuses on Peter Singer’s book, One World: The Ethics of Globalisation, and a reading of it recently presented by M. Ali Khan. Khan’s response to Singer is acutely critical, but ultimately fails to situate Singer’s offering in its proper historical context. In this sense, Khan’s response is not sufficient. We demonstrate that Singer’s offering is permeated by a universalising discourse marked by asymmetric power relations clearly described by Edward Said in Orientalism and, more surprisingly, by Fyodor Dostoyevsky in The Possessed. We illustrate how Singer’s narrative and the counter-narrative of Khan represent a continuation of a longer historical disputation between the West and the East.Orientalism, Globalisation, Economy, Language, Translation, Communication, Domination, Dialogue, Local, Global, Community

European Option Pricing with Liquidity Shocks

We study the valuation and hedging problem of European options in a market subject to liquidity shocks. Working within a Markovian regime-switching setting, we model illiquidity as the inability to trade. To isolate the impact of such liquidity constraints, we focus on the case where the market is completely static in the illiquid regime. We then consider derivative pricing using either equivalent martingale measures or exponential indifference mechanisms. Our main results concern the analysis of the semi-linear coupled HJB equation satisfied by the indifference price, as well as its asymptotics when the probability of a liquidity shock is small. We then present several numerical studies of the liquidity risk premia obtained in our models leading to practical guidelines on how to adjust for liquidity risk in option valuation and hedging.Comment: 25 pages, 6 figure

Resonating Experiences of Self and Others enabled by a Tangible Somaesthetic Design

Digitalization is penetrating every aspect of everyday life including a human's heart beating, which can easily be sensed by wearable sensors and displayed for others to see, feel, and potentially "bodily resonate" with. Previous work in studying human interactions and interaction designs with physiological data, such as a heart's pulse rate, have argued that feeding it back to the users may, for example support users' mindfulness and self-awareness during various everyday activities and ultimately support their wellbeing. Inspired by Somaesthetics as a discipline, which focuses on an appreciation of the living body's role in all our experiences, we designed and explored mobile tangible heart beat displays, which enable rich forms of bodily experiencing oneself and others in social proximity. In this paper, we first report on the design process of tangible heart displays and then present results of a field study with 30 pairs of participants. Participants were asked to use the tangible heart displays during watching movies together and report their experience in three different heart display conditions (i.e., displaying their own heart beat, their partner's heart beat, and watching a movie without a heart display). We found, for example that participants reported significant effects in experiencing sensory immersion when they felt their own heart beats compared to the condition without any heart beat display, and that feeling their partner's heart beats resulted in significant effects on social experience. We refer to resonance theory to discuss the results, highlighting the potential of how ubiquitous technology could utilize physiological data to provide resonance in a modern society facing social acceleration.Comment: 18 page

Pedagogy on the Ethnomathematics--Epistemology Nexus: A Manifesto

In this paper, we will elaborate on a pronouncement that should be at the onset of any study in epistemology and ethnomathematics, namely, we will argue that learners do think mathematically and it is our responsibility as educators to recognize and appreciate their modes of mathematical reasoning. We will conduct our study in five parts. Following a brief introduction, in the second part, we will briefly discuss some of the critical tenets of epistemology especially as it applies to mathematics. The third part will be devoted to elucidating the basic nomenclature and hypotheses associated with ethnomathematics. In the fourth part we will expound on the organic and intrinsic relationship between these two fields. Lastly, we will propose some changes in the way academic mathematicians regard philosophy and pedagogy of mathematics that, in our opinion, will facilitate students’ understanding of the cultural aspects of mathematics

An Important Historical Milestone: The Classification of the Cubic Equations

This article investigates the use of the history of mathematics as a pedagogical tool for the teaching and learning of mathematics, using the history of the cubic equation as a specific example.Cubic equations arise intrinsically in many applications in natural sciences and mathematics. For example, in physics, the solutions of the equations of state in thermodynamics, or the computation of the speed of seismic Rayleigh waves require the solutions of cubic equations. In mathematics, they are instrumental in solving the quartic equations, for in the process, these are reduced to cubic equations. The impossibility of trisecting an angle or doubling a cube using only a straightedge and compass is equivalent to solving some cubic equations. As the name implies, the cubic spline approximation, an important tool in numerical analysis, also entails working with cubic functions. Although cubic equations were explored by the ancient Babylonian, Greek, Chinese, Indian, and Egyptian scholars, it took the collective work of many well-known mathematicians such as Diophantus, Archimedes, Fibonacci, del Ferro, Khayyam, Tartaglia, Cardano, Viète, Descartes, and Lagrange to finally obtain a full solution. Our goal in this paper is to investigate one of the most formidable steps in this extensive and prolific history, namely the complete classification of the cubic equations by Omar Khayyam in eleventh century, who was the first scholar to classify cubic equation and hence facilitate a methodical and logical approach to obtaining a general solution

Single CNC machine scheduling with controllable processing times to minimize total weighted tardiness

Cataloged from PDF version of article.Advanced manufacturing technologies, such as CNC machines, require significant investments, but also offer new capabilities to the manufacturers. One of the important capabilities of a CNC machine is the controllable processing times. By using this capability, the due date requirements of customers can be satisfied much more effectively. Processing times of the jobs on a CNC machine can be easily controlled via machining conditions such that they can be increased or decreased at the expense of tooling cost. Since scheduling decisions are very sensitive to the processing times, we solve the process planning and scheduling problems simultaneously. In this study, we consider the problem of scheduling a set of jobs on a single CNC machine to minimize the sum of total weighted tardiness, tooling and machining costs. We formulated the joint problem, which is NP-hard since the total weighted tardiness problem (with fixed processing times) is strongly NP-hard alone, as a nonlinear mixed integer program. We proposed a DP-based heuristic to solve the problem for a given sequence and designed a local search algorithm that uses it as a base heuristic

Practical approach to early postoperative management of lung transplant recipients

Meticulous attention to detail during the early postoperative period after lung transplantation is crucial for the overall success of the procedure. It starts in the intensive care unit with the initiation of immunosuppression, implementation of anti-infective strategies and stabilisation of respiratory function. The subsequent days and weeks on the regular ward focus on titration of immunosuppressive drugs, vigilant fluid management, early mobilisation and initiation of physiotherapy. In parallel, the lung transplant recipients are actively taught about self-monitoring and self-management strategies to allow for a smooth transition to outpatient follow-up care. This article intends to communicate the practical aspects and principles of the patient management used at the authors' centre on a daily basis by a multi-disciplinary transplant team, having at its core both a transplant pulmonologist and a thoracic surgeon. It focuses on the first month after lung transplantation, but does not cover surgical techniques, rare complications or long-term management issues of lung transplant recipients. The target audience of this practical guide are advanced trainees of pulmonology, thoracic surgery, intensive care, anaesthesiology and other clinicians involved in the early postoperative care of lung transplant recipients either in the intensive care unit or on the peripheral ward

Photoluminescence and concentration quenching of Pr3+ doped BaTa2O6 phosphor

The pure and Pr3+ doped TTB-BaTa2O6 phosphors were obtained by the solid state reaction method at 1 425 °C for 20hours. X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM) analyses confirmed a single phase of BaTa2O6up to 10 mol % Pr2O36. SEM analysis also shows that BaTa2O6 grain size decreased with the increasing Pr2O36 concentration.The chemical composition of Pr3+ doped BaTa2O6 structures was confirmed by Energy Dispersive Spectroscopy(EDS) analysis. BaTa2O6:Pr3+ phosphors exhibited on a strong red emission at 620,9 nm, a green emission at 548,3 nm and a red emission at 655,2 nm. Emission intensity increased with Pr3+ doping concentration up to 1,5 mol %, then decreased due to concentration quenching

Daha sonra bir hisse senedi performans ölçümü olarak piyasa defter değeri, panel veri analizleri kullanılarak etkinliğin oransal değişimiyle regresyona tabi tutulmuştur. SFA, şube başına çalışan sayısı ve banka yaşı hisse senetlerinin etkinlikleri üzerinde negatif yoğunlaşma oranı ve sermaye yeterlilik oranı pozitif bir etkiye sahip olduğunu göstermiştir. Sonuçlar aynı zamanda hisse senedi performansını değerlendirirken bankaların etkinlik seviyesini anlamlı bir faktör olarak dikkate aldıklarını göstermiştir.This study aims to investigate the relationship between efficiency and the stock performance of the banking sector in Turkey. Efficiency analysis is conducted via Stochastic Frontier Analysis (SFA). Subsequently, the market-to-book value as a measure of stock performance is regressed against the percentage change in efficiency using panel data analysis. SFA shows that the concentration ratios and capital adequacy ratio have a positive effect on the efficiency of stocks, whereas the number of employees per unit of branches and age influence stocks negatively. The results also show that investors perceive efficiency to be a significant factor in terms of stock performance
