Cópulas: un nuevo enfoque para la modelización de campos aleatorios
No full textEl estudio de fenómenos espacio-temporales que actúan aleatoriamente se modelan por medio de métodos geo estadísticos, desarrollados originalmente para predecir la distribución de probabilidad para operaciones mineras, (Giraldo, 2010). Algunos de estos métodos son: el variograma, que describe la estructura de dependencia espacial bajo la media, y el Kriging, como la metodología de predicción espacial. Ambos métodos son sensibles a observaciones atípicas y están fuertemente influenciadas por la distribución marginal del campo aleatorio subyacente. En este trabajo, como una alternativa a la modelización tradicional de campos aleatorios, se propone el uso de funciones cópula. En la primera etapa, se realiza el análisis exploratorio de datos, buscando identificar la forma de la estructura de dependencia espacial. Por ello, se presenta la cópula empírica, que permite identificar la dependencia mediante el cálculo de rangos y la distribución empírica. Posteriormente, se define la distribución multivariada del campo en términos de sus marginales con ayuda del teorema de Sklar, formando una función de distribución alterna para el campo. Dicha distribución quedará expresada en términos de la distancia entre los lugares de observación. En la tercera etapa, se describen los procedimientos empleados para identificar la cópula que mejor se aproxima a la cópula empírica, la cual se denomina cópula _optima, seleccionada a partir de un conjunto de copulas, llamadas cópulas elípticas, usando el estadístico desarrollado por (Genest, 2009) centrado en un blanket test. Una vez detectada la cópula que corresponderá al modelo de dependencia espacial, se realiza predicción, aplicando los procedimientos propuestos por (Kazianka, 2010) y (Kazianka, 2012), llamados kriging indicador, disyuntivo y trans-gaussiano, todos estos se aplican usando el modelo cópula.Abstract. The study of spatiotemporal phenomena that uctuate randomly modeled using geostatistical methods, originally developed to predict the probability distribution for mining operations (Giraldo, 2010). Some of these methods are: the variogram, which describes the spatial dependence structure under the average, and the Kriging, such as spatial prediction methodology. Both methods are sensitive to outliers and are strongly in uenced by the marginal distribution of the underlying random field. In this work, as an alternative to traditional random field modeling, we propose the use of mating features. In the first stage, we performed exploratory data analysis, seeking to identify the form of the spatial dependence structure. Therefore, we present the empirical copula, which identifies the dependence by calculating ranges and the empirical distribution. Subsequently, it defines the multivariate distribution of the field in terms of its marginal theorem using the Sklar, forming alternating distribution function for the field. This distribution will be expressed in terms of the distance between the observation points. In the third stage, we describe the procedures used to identify the copula that best approximates the empirical copula, which is called optimal intercourse, selected from a set of copulation, copulation calls elliptical, using the statistic developed by (Genest , 2009) focused on a "blanket test". Once detected the copula which corresponds to the spatial dependence model, prediction is performed by applying the procedures proposed by (Kazianka, 2010) and (Kazianka, 2012), called indicator kriging, disjunctive and trans-Gaussian, these are applied using the copula modelMaestrí

Paglalagalag sa Multong-Modernidad ng Lungsod at Nayon: Tatlong Akda ni Jun Cruz Reyes bilang Paglalaboy-laboy at Pananaliksik
No full textMalapitang binasa ng papel na ito ang tatlong pampanitikang akda ni Jun Cruz Reyes—Ilang Taon na ang Problema Mo?, Tutubi, Tutubi, ‘Wag Kang Magpahuli sa Mamang Salbahe, at Ang Huling Dalagang Bukid at ang Authobiography na Mali: Isang Imbestigasyon—upang ipanukala ang palaboy bilang Filipinong katapat ng Kanluraning flaneur. Sinundan ang pagbubulakbol at pagbubulay-bulay ng palaboy sa tatlong akda, kung saan itinutumbas ito sa mga tauhan ni Reyes, o kay Reyes mismo. Pinagana ang palaboy—na manunulat, mananaliksik, at manlalakbay din—upang lampasan ang pigura ng flaneur. Ginawa ito sa pamamagitan ng pagsasakasaysayan ng pag-usbong kapwa ng flaneur at ng palaboy. Matatagpuan ang huli sa mga akda ni Reyes: isang aktibistang mag- aaral sa mga unang araw ng Batas Militar; isang mananaliksik na nakikipanayam at nakikipamuhay sa mga nasa laylayan ng lipunan—mga katutubo, isang sniper at organisador para sa rebolusyonaryong kilusan, isang lider-kabataan sa siyudad—at isang guro’t manunulat na tumatawid-tawid sa pagitan ng lungsod kung saan siya nagtuturo at ng kaniyang kinalakhang baryo sa Bulacan. Ang pagsipat sa mga palaboy na ito at sa iba’t ibang uri ng kanilang paggalaw at paglalakbay ay pagmumuni rin tungkol sa mga lungsod at kanayunan at kanilang sari-saring ugnayan.

Closely reading three literary works of Jun Cruz Reyes—Ilang Taon na ang Problema Mo?, Tutubi, Tutubi, ‘Wag Kang Magpahuli sa Mamang Salbahe, and Ang Huling Dalagang Bukid at ang Authobiography na Mali: Isang Imbestigasyon— this paper proposes the image and personage of the palaboy as a Filipino counterpart of the Western flaneur. The palaboy and his meanderings and ruminations are followed and situated in these three works, associating them both with Reyes’s characters and Reyes the author himself. The palaboy—which the paper relates to figures like the writer-researcher and the traveler—is mobilized to engage with and go beyond the figure of the flaneur. This is done by distinguishing the historical contexts giving rise to the flaneur and the palaboy, and locating the latter in Reyes’s three works. In these works, the palaboy takes the form of a student activist during the first days of Martial Law; a researcher interviewing and living with society’s marginalized—indigenous people, a sniper and an organizer for a revolutionary movement, and a youth leader in the cities—and a writer-teacher going back-and-forth the city where he teaches, and his cherished hometown in Bulacan. Looking closely at these three palaboys and the contexts of their moving about and travels also allows for a reflection on the urban and rural spaces and how they variously intertwine with each other
Jen Delos Reyes
No full textProjects in this collection: Open Engagement
From http://www.jendelosreyes.com/about: Jen Delos Reyes was born in the city of Winnipeg, Manitoba, Canada, and educated first in its local music scene of the mid-90’s infused with the energy of Riot grrrl and DIY, and then in its university. [1] How she works today is rooted in what she learned in her formative years as a show organizer, listener, creator of zines, and band member. Graduate work at the University of Regina made the space possible for her to see her work as an organizer as a key component of her continued creative work.
Jen Delos Reyes is a \u27farmer of sorts and an artist of sorts\u27[2], educator, writer, and radical community arts organizer. She is defiantly optimistic, a friend to all birds, and proponent that our institutions can become tender and vulnerable. Her practice is as much about working with institutions as it is about creating and supporting sustainable artist-led culture.
Delos Reyes worked within Portland State University from 2008-2014 to create the first flexible residency Art and Social Practice MFA program in the United States and devised the curriculum that focused on place, engagement, and dialogue. The flexible residency program allowed for artists embedded in their communities to remain on site throughout their course of study.
She worked with the Portland Art Museum from 2009-14 on a series of programs and integrated systems that allowed artists to rethink what can happen in a museum, and reinvigorate the idea of the museum as a public space.
From 2015-2022 Delos Reyes was the Associate Director of the School of Art & Art History of the University of Illinois, Chicago’s only public research university, where she taught in the departments of Art and Museum and Exhibition Studies.
She was the Director and founder of Open Engagement, an international annual conference on socially engaged art that was active between 2007-2019 and hosted ten conferences in two countries at locations including the Queens Museum in New York. After over a decade of large scale organizing she is now focused on work on the scale of her life.
She is the author of I’m Going to Live the Life I Sing About in My Song: How Artists Make and Live Lives of Meaning, Everything You Ever Wanted to Know About Public Engagement But Were Afraid to Ask, and Defiantly Optimistic: Turning Up in a World on Fire.
Delos Reyes divides her time between Chicago, IL where she is the founder of Garbage Hill Farm, and Ithaca, NY where she is an Associate Professor of Art at Cornell University.

Formulation of a proposal for the use of organic waste through the composting generated by the microenterprise "Frutos del campo a la mesa S.A.S" located in Tunja, Boyaca
No full textLa microempresa “Frutos del campo a la mesa S.A.S” ubicada en Tunja, Boyacá, genera alrededor de 441,4 kg/mes de residuos sólidos orgánicos, que no reciben ningún tipo de aprovechamiento y son llevados a disposición final al relleno sanitario Parque Ambiental de Pirgua. La gestión inadecuada de estos causa impactos ecológicos, como olores ofensivos y proliferación de vectores, económicos, como el incremento de costos en disposición final y sociales como afectaciones a la salud y seguridad alimentaria. A partir de la situación presentada, se desarrolló una propuesta de compostaje que permita el aprovechamiento de los residuos de fruta producidos por la microempresa. Para llevar a cabo esta investigación,se realizaron visitastécnicas a la zona de estudio donde se hizo una entrevista, con el fin de diagnosticar el estado actual referente al manejo de los RSO, se logró identificar que durante las etapas de producción dos y cuatro, la generación de RSO para los meses evaluados fue de 1765,4 kg. Posteriormente, se realizó un análisis comparativo de los diferentes métodos de compostaje, el cual, arrojó las pacas digestoras como la alternativa más viable y eficiente para ser usada en el diseño de la propuesta. Esta se diseñó mediante cuatro fases, iniciando con la separación en la fuente, adaptación del centro de acopio, diseño del método y comercialización del compost. Finalmente, el proyecto da como resultado una solución viable a la problemática identificada, brindando un análisis en pro de aportar a una economía circular.Ingeniero AmbientalPregradoThe microenterprise "Frutos del campo a la mesa S.A.S" located in Tunja, Boyacá, generates around 441,4 kg/month of organic solid waste which does not receive any type of use and is taken to the Pirgua Environmental Park landfill for final disposal. The inadequate management of these causes’ ecological impacts such as harmful odors and proliferation of vectors, economic impacts such as the increased costs at the final disposal and social impacts as bad effects on health and food safety. Based on the situation presented, a composting proposal was developed that allows the use of fruit residues produced by the microenterprise. To carry out this research, technical visits were made to the study area where an interview was made in order to diagnose the current state regarding the management of organic solid waste. It was possible to identify that during production stages two and four the generation of organic waste for the months evaluated was 1765,4 kg. Subsequently, a comparative analysis of the different composting methods was carried out, which resulted in digester bales as the most viable and efficient alternative to be used in the design of the proposal. This was designed through four phases, starting with separation at the source, adaptation of the collection center, design of the method and commercialization of the compost. Finally, the project results in a viable solution to the identified problem providing an analysis in favor of contributing to a circular economy

Mongolian Stress, Licensing, and Factorial Typology
No full textThis paper examines the analysis and typology of prominence-based stress systems, which do not call on binary rhythms but depend solely on factors such as syllable weight or sonority, peripherality, and nonfinality in locating stress (Prince 1983, 1990; Prince & Smolensky 1993). Four prominence-driven constraints are defined which position stress independent of foot structure. Pursuing the optimality-theoretic hypothesis that typology derives from factorial constraint ranking, it is established that reranking accurately captures attested variation, and further, that the range of prominence-driven patterns is richer than previous conceptions, including variation in nonfinality effects. Two important empirical and theoretical findings are presented. First, new data from East Mongolian dialects are introduced, correcting a misinterpretation of the Khalkha stress pattern and illuminating the analysis with a case uniquely employing all four prominence-driven constraints. Second, opposite-edge default is argued to be a categorical licensing effect, informed by the typological result that nonfinality only fails to cooccur with opposite-side systems when the default is to the right. This finds new evidence for Zoll's (1996) licensing account of conflicting directionality and offers an argument against alternative foot-based analyses.The definitive version of this paper was published in Phonology at Santa Cruz and is available at http://linguistics.ucsc.edu/research/publications/pasc/index.htmlWalker, R.
