Para ello, se realizara una revisión sobre los temas de no-linealidad y contagio, permitiendo determinar el comportamiento de las economías, y de sus _índices accionarios, frente a los shocks. Esto permitirá determinar los patrones que siguen las economías y los posibles efectos de spillover, con ello se puede diseñar un plan de contingencia frente a las futuras crisis, y sentar señales de alerta temprana, reduciendo los efectos de las crisis.

The purpose of the present study was to determine the relationship between a subject's percepteptanalysis as revealed by certain indices of the Rorschach and marital success or failure.

The purpose of this study was to compare a group of college smokers with a similar group of college nonsmokers on eleven Rorschach indices. The sources of data were thirty-five smokers and thirty-five nonsmokers enrolled in Introductory English courses at Texas Christian University during the 1971-1972 academic year.

La investigación que ofrecemes como Tesis, tuvo dos momentos bien marcadas en el diseño y elaboración. El primera, que cubrió desde la idea de hallar deflactores propios de precios de la empresa hasta la aplicación de las fórmulas de Laspeyres y de Paaechs, pretendiendo copiar los estadígrafes usados en los análisis macroeconómicos de precios. La resultante fueron números indices inconsistsentes y sesgados en relación a los indicadores del nivel general de precios en nuestra economía, para el mismo período. ¿La causa? La ausencia de una canasta estable de elementos comprados y vendidos en términos mensuales. Como se sabe, no existen los flujos regulares de entradas y salidas de mercancías en las transacciones económicas de las empresas; la corriente es que ellos se supediten a pelíticas concretas de producción, de inventarios, etc. A principios de 1982, y después de 3 meses de pruebas, abandonamos el plan: creíamos imposible preparar índices estadísticos de precios en el plana microecenómica, por no disponer de métodos apropiados a las condiciones reales descritas.

Autor no autoriza el acceso a texto completo de su documento / Tesis para optar al grado de Magíster en Finanzas / Este trabajo analiza la existencia de periodicidades en los retornos de ocho índices accionarios latinoamericanos: Bovespa, IBC, IGBC, IGBVL, IGPA, IPSA, IPyC y Merval por medio de dos técnicas. La primera es la de estimación de modelos de regresión lineal de los retornos contra un set de variables dummies, una por cada día de la semana. La varianza sigue un modelo GARCH(2,2), de forma de tomar en cuenta la desviación de los supuestos clásicos en el comportamiento de retornos accionarios. Luego, se utiliza un test de periodicidades desarrollado por Hinich (2000), que modela los retornos bajo un comportamiento de Random Modulated Periodicity, basado en el análisis de Fourier. El primer análisis da como resultado que el comportamiento periódico no es un fenómeno constante en todos los índices estudiados. El segundo arroja evidencia de periodicidades sutiles. Esto cambia al analizar secciones de las series de tiempo en las que se comprueba la existencia del efecto fin de semana, en donde los retornos muestran ser altamente periódicos a través de toda la semana.

The monitoring of continental and global scale net primary production remains a major focus of satellite-based remote sensing. Potential benefits which follow are diverse and include contributions to, and improved scientific understanding of, ecological systems, rangeland management, famine warning, agricultural commodity trading, and the study of global climate change.A NOAA-AVHRR data set containing monthly observations of green vegetation cover over a ten year period was acquired and analysed, to extract information on seasonal conditions. The data were supplied as a vegetation index, commonly known as the Normalised Difference Vegetation Index (NDVI), with a spatial resolution of approximately five km. The data set was acquired from three different satellites, and calibration problems were known to exist. A new technique was developed to estimate, and subsequently remove, the calibration bias present in the data.Monthly rainfall measurements were used as surrogate ground truth to validate the NDVI data. For regions of native vegetation, linear models relating NDVI to previous rainfall were derived, using transfer function techniques in common use in systems engineering. The models demonstrate that, in mid-latitude regions, the NDVI is a linear function of rainfall recorded over the preceding seven or eight months.Annual summaries of the image data were developed to highlight the amount and timing of plant growth. Three fundamental questions were posed as an aid to the development of the summary technique: where, when and how much? These summaries highlight the extraordinary spatial and temporal variations in plant growth, and hence rainfall, over much of Western Australia each year.Standard analysis techniques used in time series analysis, such as classical decomposition, were successfully applied to the analysis of NDVI time series. These techniques highlighted ++ / structural differences in the image data, due to land use, climatic factors and vegetation type.Overall, the results of the research undertaken in this study, using NOAA-AVHRR data in Western Australia, demonstrate that vegetation indices acquired from satellite platforms can be used to monitor continental scale seasonal conditions in an effective manner. As a consequence of these results, further research using this type of data is proposed in rangeland management and climate change modelling.

Urban racial segregation has been a problem to many U.S. cities. Many researchers have interested on the urban segregation issues since long time ago. To understand and plan a better community, urban planners needs to know how to measure the segregation and interpret the results. However, over the past several decades, many scientists have proposed many types of urban segregation measures. Although a few of them are commonly used nowadays, this doesn?t mean the other measures are not appropriate. Disregarding the fact that some of the measures are mostly used or easily calculated this paper attempts to gather many of the proposed and the most discussed measures for comparison. The results of the comparison were categorized in one group measure, two group measure, and multi group measure. They are also divided in to the five dimensions of segregation such as the evenness, exposure, concentration, clustering, and centralization. Two U.S. metropolitan cities that are different in racial proportion, Houston, TX and Philadelphia, PA, were selected for the comparison. All the selected measures are evaluated in several criteria such as the scale, level of measures, data required, level of complexity, and tendencies of using different census data.

Finansų rinkos skirstomos į pinigų ir vertybinių popierių rinkas. Autorė trumpai apžvelgia vertybinių popierių rinkos bei šiuo metu svarbiausių pasaulio biržų atsiradimą, tačiau didžiausias dėmesys skiriamas Lietuvos vertybinių popierių rinkai, nes šio darbo tikslas yra išanalizuoti Lietuvos vertybinių popierių rinką 1993 – 2005 metais. Darbe išnagrinėtos vertybinių popierių formos bei rūšys, kurias galima sugrupuoti į nuosavybės vertybinius popierius, skolos vertybinius popierius bei išvestines priemones. Taip pat pateikiami svarbiausi akcijų kainas veikiantys veiksniai. Apžvelgiamos Lietuvos vertybinių popierių rinką reguliuojančios institucijos, jų funkcijų kitimą nuo 1993 metų ir pateikiami duomenys apie šių institucijų atliktą darbą. Apžvelgiami ir rinkos dalyviai bei pateikiamas jų skaičiaus kitimas. Darbo paskutiniame skyriuje autorė analizuoja Lietuvos vertybinių popierių rinkos duomenis – apyvartą, kapitalizaciją, apyvartos pasiskirstymą pagal prekybos sąrašus bei pagal sandorių tipus. / Financial markets are divided into money market and securities market. Although authoress writes shortly about history of securities market and history of the most important Stock Exchanges of the world, the aim of this paperwork is to observe the evaluation of the Lithuanian Securities market. The object of the paperwork – the analysis of Securities market of Lithuania in 1993 – 2005. The forms and kinds of securities are analyzed in this paper work. It is possible to group securities into three kinds: proprietary, debt securities and financial derivatives. Authoress also names factors, which influence prices of equities. Authoress analyzes the Institutions of the Securities market of Lithuania, functions and variation of these functions since 1993 and participants of securities market of Lithuania and gives variation of their number.
