Calibration of stochastic volatility models via second order approximation: the Heston model case

Using a suitable Hull and White type formula we develop a methodology to obtain asecond order approximation to the implied volatility for very short maturities. Using thisapproximation we accurately calibrate the full set of parameters of the Heston model. Oneof the reasons that makes our calibration for short maturities so accurate is that we alsotake into account the term-structure for large maturities. We may say that calibration isnot "memoryless", in the sense that the option's behavior far away from maturity doesinfluence calibration when the option gets close to expiration. Our results provide a wayto perform a quick calibration of a closed-form approximation to vanilla options that canthen be used to price exotic derivatives. The methodology is simple, accurate, fast, andit requires a minimal computational cost.

Multi-sample analysis of moment-structures: Asymptotic validity of inferences based on second-order moments

In moment structure analysis with nonnormal data, asymptotic valid inferences require the computation of a consistent (under general distributional assumptions) estimate of the matrix $\Gamma$ of asymptotic variances of sample second--order moments. Such a consistent estimate involves the fourth--order sample moments of the data. In practice, the use of fourth--order moments leads to computational burden and lack of robustness against small samples. In this paper we show that, under certain assumptions, correct asymptotic inferences can be attained when $\Gamma$ is replaced by a matrix $\Omega$ that involves only the second--order moments of the data. The present paper extends to the context of multi--sample analysis of second--order moment structures, results derived in the context of (simple--sample) covariance structure analysis (Satorra and Bentler, 1990). The results apply to a variety of estimation methods and general type of statistics. An example involving a test of equality of means under covariance restrictions illustrates theoretical aspects of the paper.

A new order, a new family and a new genus of Paleozoic Radiolaria: Latentifistularia, Cauletellidae and Cauletella

Since the genus Deflandrella De Wever and Caridroit 1984 is a homonym of Deflandrella Loeblich and Tappan 1961, the new name Cauletella is :herein proposed, and the genus is redefined. Consequently, the family name Deflandrellidae De Wever and Caridroit, previously erected, becomes Cauletellidae, and its definiton is emended. This important radiolarian group, typical of the Permian times, is closely related to the families Ruzhencevispongidae Kozur 1980 and Latentifistulidae Nazarov and Ormiston 1983. These Paleozoic radiolarians are characterized by an initial skeleton quite different from that of the other radiolarian orders and are assigned to the new order Latentifistularia, which is herein defined and briefly discussed.

A avaliação de desempenho como factor de motivação

Este estudo, realizado sobre a temática “A Avaliação de Desempenho como Factor de Motivação”, através da revisão bibliográfica e de um estudo de caso na Sociedade Cabo-verdiana de Tabacos, SA, teve como objectivo mostrar os impactos da avaliação de desempenho na motivação dos colaboradores. O trabalho encontra-se estruturado em quatro capítulos, sendo que no primeiro e segundo fez-se uma revisão bibliográfica, para uma melhor fundamentação teórica do trabalho. O terceiro capítulo, refere-se ao estudo de caso feito na referida empresa, onde foi aplicado um questionário para apurar, acerca da percepção que os colaboradores têm do sistema de avaliação de desempenho que são submetidos e da adequabilidade do mesmo à estrutura da organização, e ainda a aplicação da teoria de Victor Vroom para medir a motivação dos colaboradores. E por último, no quarto capítulo, referimos às conclusões e subsequentes recomendações. Da análise dos dados recolhidos na empresa, verificamos que o nível motivacional com que a maioria dos colaboradores da SCT, SA desenvolvem as suas tarefas está abaixo da média, o que conduziu-nos a conclusão de que eles estão desmotivados, pelo que a empresa deverá criar medidas que possam estimular os colaboradores de forma a reverter essa situação. This study about the topic "Performance Evaluation as Motivation Factor", through literature review and a case study in Sociedade Cabo-verdiana de Tabacos, SA, aimed to show the impact of performance evaluation on employee motivation. The work is structured in four chapters and in the first and second we did a literature review for better theoretical foundation of the work. The third chapter refers to the case study in the company mentioned above, which was administered a questionary to know what the employees think about the performance evaluation system in the company, and so the application of Victor Vroom´s theory to measure the employees motivation. And finally in the fourth chapter we refer some conclusions and recommendations for the company. After the analysis of the data given in the company, we realized that the motivation level witch the majority of the employees in SCT, SA work is under the average, what made us come to the conclusion that they are not motivated. So we suggest the company to develop strategies to stimulate the employees in order to reverse this situation

Plastic brain mechanisms for attaining auditory temporal order judgment proficiency.

Accurate perception of the order of occurrence of sensory information is critical for the building up of coherent representations of the external world from ongoing flows of sensory inputs. While some psychophysical evidence reports that performance on temporal perception can improve, the underlying neural mechanisms remain unresolved. Using electrical neuroimaging analyses of auditory evoked potentials (AEPs), we identified the brain dynamics and mechanism supporting improvements in auditory temporal order judgment (TOJ) during the course of the first vs. latter half of the experiment. Training-induced changes in brain activity were first evident 43-76 ms post stimulus onset and followed from topographic, rather than pure strength, AEP modulations. Improvements in auditory TOJ accuracy thus followed from changes in the configuration of the underlying brain networks during the initial stages of sensory processing. Source estimations revealed an increase in the lateralization of initially bilateral posterior sylvian region (PSR) responses at the beginning of the experiment to left-hemisphere dominance at its end. Further supporting the critical role of left and right PSR in auditory TOJ proficiency, as the experiment progressed, responses in the left and right PSR went from being correlated to un-correlated. These collective findings provide insights on the neurophysiologic mechanism and plasticity of temporal processing of sounds and are consistent with models based on spike timing dependent plasticity.

A total order in [0,1] defined through a 'next' operator

A `next' operator, s, is built on the set R1=(0,1]-{ 1-1/e} defining a partial order that, with the help of the axiom of choice, can be extended to a total order in R1. Besides, the orbits {sn(a)}nare all dense in R1 and are constituted by elements of the samearithmetical character: if a is an algebraic irrational of degreek all the elements in a's orbit are algebraic of degree k; if a istranscendental, all are transcendental. Moreover, the asymptoticdistribution function of the sequence formed by the elements in anyof the half-orbits is a continuous, strictly increasing, singularfunction very similar to the well-known Minkowski's ?(×) function.
