12	The multidimensional relations between the Wari and the Moche states of Northern Peru / Relaciones multidimensionales entre los estados Wari y Moche del norte del Perú Castillo, Luis Jaime, Fernandini B., Francesca, Muro Y., Luis 10 April 2018 (has links) (PDF) This paper explores how archaeology can study the relationships between complex multidimensional societies in critical periods of their development through an analysis of the multiple variables, circumstances and contingencies that define social interactions. By focusing on the archaeological record of San José de Moro, an important funerary and ceremonial center in the Jequetepeque valley, the authors approach the multifaceted natures and purposes behind the relationships between the Moche States of northern coastal Peru and the southern Andean Wari during the end of the Early Intermediate Period and the Middle Horizon. / El presente artículo explora cómo la arqueología puede estudiar las relaciones entre sociedades complejas durante periodos críticos de su desarrollo, a través del análisis de las múltiples variables, circunstancias y contingencias que definen las interacciones sociales. Mediante el estudio de los contextos y objetos provenientes de San José de Moro, un importante centro funerario y ceremonial en el valle del Jequetepeque, los autores abordan las naturalezas y propósitos que se traslapan detrás de las relaciones entre los Estados mochica del norte del Perú y la sociedad wari de la sierra sur, durante el Periodo Intermedio Temprano y el Horizonte Medio.

13	Modelo de competitividad para una universidad privada al interior del DEMRE Nuñez Andrades, Cristián Marcelo January 2013 (has links) Ingeniero Civil Industrial / En la actualidad, la educación superior en Chile se caracteriza por estar inserta en una lógica de mercado, en el que las instituciones de educación superior deben competir por captar el mayor número de estudiantes que siguen un perfil determinado por la institución. A partir de lo anterior, es relevante la comprensión de cómo los estudiantes eligen las universidades y cuáles son los driver que determinan su preferencia por una universidad dada. Para ello se generarán dos modelos orientados a comprender el proceso de decisión realizado por los estudiantes. El primero consiste en un análisis de las postulaciones de los estudiantes a través de la formulación del modelo MDS sobre las postulaciones que estos realizan. El segundo corresponde a un modelo de elección discreta que modela la decisión de postulación a la universidad estudiada, de esta forma también se busca comprender el impacto de la difusión sobre la decisión de postulación. Al realizar la aplicación del modelo MDS se logra determinar que la principal competencia para la universidad en estudio en la región metropolitana, corresponden a las universidades Mayor, Universidad Diego Portales y Universidad del Desarrollo. Cabe destacar que esta competencia se desarrolla principalmente entre carreras, siendo la universidad en estudio preferida en las áreas de Derecho y Administración y Comercio. Dentro de las carreras de salud se observa que existen variaciones según la carrera de estudio, sin embargo, al comparar con la principal universidad en competencia, que la Universidad Mayor, se observa que la universidad en estudio es menos preferida para estas carreras. Del modelo de postulación, se observa que la principal variable que determina la postulación de un estudiante corresponde a sus resultados PSU, siendo los estudiantes que pertenecen a los primeros 5 deciles de resultados PSU los que poseen mayor propensión de postulación. Al realizar el análisis del impacto de postulación, se observa que esta es significativa en la decisión de postulación, en particular, se tiene que el efecto que explica corresponde a las actividades distintas sobre el estudiante en el período.

14	Modeling of census data in a multidimensional environment Günzel, Holger, Lehner, Wolfgang, Eriksen, Stein, Folkedal, Jon 13 June 2023 (has links) The general aim of the KOSTRA project, initiated by Statistics Norway, is to set up a data reporting chain from the norwegian municipalities to a central database at Statistics Norway. In this paper, we present an innovative data model for supporting a data analysis process consisting of two sequential data production phases using two conceptional database schemes. A first data schema must provide a sound basis for an efficient analysis reflecting a multidimensional view on data. Another schema must cover all structural information, which is essential for supporting the generation of electronic forms as well as for performing consistency checks of the gathered in-formation. The resulting modeling approach provides a seamless solution for both proposed challenges. Based on the relational model, both schemes are powerful to cover the heterogeneity of the data source, handle complex structural information, and to provide a versioning mechanism for long term analysis. info:eu-repo/classification/ddc/004 ddc:004
15	Códigos y grafos sobre anillos de enteros complejos Martínez Fernández, María del Carmen 26 March 2007 (has links) El objetivo de esta tesis es definir códigos perfectos sobre diferentes espacios de señal multidimensionales. Para resolver este problema, esta memoria presenta una relación original entre las Teorías de Grafos, Números y Códigos. Uno de nuestros principales resultados es la propuesta de una métrica adecuada sobre constelaciones de señal de tipo cuadrático, hexagonal y cuatro-dimensional. Esta métrica es la distancia entre los vértices de una nueva clase de grafos de Cayley definidos sobre diferentes anillos de enteros, en concreto, los enteros de Gauss, Eisenstein-Jacobi y Lipschitz. Así, resolvemos el problema de Teoría de Grafos conocido como el cálculo del conjunto perfecto dominante sobre las familias de grafos definidas en esta memoria. Para cada caso, daremos una condición suficiente para obtener dicho conjunto. La obtención de estos conjuntos de dominación implica directamente la construcción de códigos perfectos sobre los alfabetos que se consideran.Además, se obtendrán algunos resultados de isomorfía y embebimiento de grafos. En particular, se establecerán las relaciones entre grafos circulantes, toroidales y los que se presentan en este trabajo. Más concretamente, se mostrará que siempre existen órdenes para los cuales un grafo Toro puede ser embebido en un grafo Gaussiano, de Esenstein-Jacobi o de Lipschitz. Esto implica que la conocida distancia de Lee es un caso particular de las métricas presentadas en este trabajo. / The aim of this work is to define perfect codes for different multidimensional signal spaces. To solve this problem, this thesis presents an original relationship among the fields of Graph Theory, Number Theory and Coding Theory. One of our main findings is the proposal of a suitable metric over quadratic, hexagonal and four-dimensional constellations of signal points. This metric is the distance among vertices of a new class of Cayley graphs defined over integer rings, namely Gaussian integers, the Eisenstein-Jacobi integers and the Lipschitz integers.A problem in Graph Theory known as the perfect dominating set calculation is solved over the families of graphs defined in this memory. A sufficient condition for obtaining such a set is given for each case. The obtention of these sets of domination directly yields to the construction of perfect codes for the alphabets under consideration. In addition, some isomorphism and graph embedding results are going to be obtained. Specially, the relations between circulant, toroidal and the graphs presented in this work are stated. In particular, there always exist orders for which a Torus graph can be embedded in Gaussian, Eisenstein-Jacobi and Lipschitz graphs. This implies that the well-known Lee distance is a subcase of the metrics presented in this research. multidimensional signal constellations perfect codes codigos perfectos Cayley graphs grafos de Cayley anillos de enteros integer rings Matemáticas 004 511 519.1
16	Estudio comparativo de métodos multidimensionales para medir la calidad de servicio según tipo de restaurante / Comparative study of multidimensional methods to measure the quality of service according type of restaurant Diaz Calizaya, Claudia Sofia, Navea Portugal, María José 02 December 2020 (has links) Actualmente, se conoce que existe una gran variedad de métodos multidimensionales que permiten medir la calidad del servicio del cliente que ofrecen los restaurantes, por lo tanto, resulta de gran importancia contar con un estudio que permita conocer los beneficios y limitaciones que tiene cada uno de estos para así aplicar el más adecuado según corresponda. Por tal motivo, el propósito de la presente investigación, es el de realizar un análisis comparativo del uso de los distintos métodos y herramientas que actualmente existen para poder medir la calidad de servicio en los distintos tipos de restaurantes. Para la realización de este trabajo de investigación se realizó una exhaustiva revisión bibliográfica, tanto en inglés como en español, de este modo se obtuvo distintos puntos de vista desde perspectivas completamente diferentes de la percepción de la calidad de servicio y la expectativa del consumidor. Cabe mencionar que la totalidad de las fuentes son actuales, dado que se encuentran entre los años de 2015 como máximo al 2020. Las fuentes encontradas mencionan que la calidad de servicio es un término que varía según el contexto en el que este sea evaluado y de manera específica dependiendo del tipo de establecimiento. Por ello, se explica que existen una gran diversidad de métodos que son empleados para medir la calidad de servicio en restaurantes: Servqual, Kano Model, Servperf y Dineserv. Por lo tanto, se concluye que de todas las herramientas y métodos que han sido comparados, Dineserv es aquel que presenta un mayor número de beneficios con respecto al resto de modelos, pues es específico para el sector de restauración. / Currently, it is known that there are a variety of multidimensional methods that allow us to measure the quality of customer service that is being offered in restaurants. Therefore, it is of huge importance to count with a study that allows knowing the benefits and limitations of each of these in order to apply the most appropriate. Due to these, the purpose of the present investigation is to make a comparative analysis of the use of the different methods and tools that currently exist to measure the quality of service depending on the restaurant type. To carry out this study, there has been an exhaustive investigation of bibliographic sources from different authors both in spanish and in english. In this way it will allow us to obtain different perspectives around the world about the perception of the quality of service and the consumer’s expectative. It is worth mentioning that the totality of the sources are current, since they are between the years of 2015 at most to 2020. The sources found mention that the quality of service is a term that varies depending on the context in which it is evaluated and to be more specific it depends on the type of establishment. Due to this, it is said that there are a variety of methods that are used to measure the quality of service in restaurants: Kano Model, Servperf and Dineserv. Because of that we can conclude that these tools and methods have been compared in terms of limitations and benefits in order to determine which of these adapts better according to the type of restaurant that is being analyzed. / Trabajo de investigación Calidad de servicio Métodos multidimensionales Percepción de la calidad Tipos de restaurante Quality of service Multidimensional methods Perception of quality Types of restaurant
17	Fatigue in chronically critically ill patients following intensive care - reliability and validity of the multidimensional fatigue inventory (MFI-20) Wintermann, Gloria-Beatrice, Rosendahl, Jenny, Weidner, Kerstin, Strauß, Bernhard, Hinz, Andreas, Petrowski, Katja 12 June 2018 (has links) (PDF) Background Fatigue often occurs as long-term complication in chronically critically ill (CCI) patients after prolonged intensive care treatment. The Multidimensional Fatigue Inventory (MFI-20) has been established as valid instrument to measure fatigue in a wide range of medical illnesses. Regarding the measurement of fatigue in CCI patients, the psychometric properties of the MFI-20 have not been investigated so far. Thus, the present study examines reliability and validity of the MFI-20 in CCI patients. Methods A convenience sample of n = 195 patients with Critical Illness Polyneuropathy (CIP) or Myopathy (CIM) were recruited via personal contact within four weeks (t1) following the transfer from acute care ICU to post-acute ICU at a large rehabilitation hospital. N = 113 (median age 61.1 yrs., 72.6% men) patients were again contacted via telephone three (t2) and six (t3) months following the transfer to post-acute ICU. The MFI-20, the Euro-Quality of Life (EQ-5D-3 L) and the Structured Clinical Interview for the Diagnostic and Statistical Manual of mental disorders DSM-IV (SCID-I) were applied within this prospective cohort study. Results The internal consistency Cronbach’s α was adequate for the MFI-total and all but the subscale Reduced Motivation (RM) (range: .50–.91). Item-to-total correlations (range: .22–.80) indicated item redundancy for the subscale RM. Confirmatory Factor analyses (CFAs) revealed poor model fit for the original 5-factor model of the MFI-20 (t2/t3, Confirmatory Fit Index, CFI = .783/ .834; Tucker-Lewis Index, TLI = .751/ .809; Root Mean Square Error of Approximation, RMSEA = .112/ .103). Among the alternative models (1-, 2-, 3-factor models), the data best fit to a 3-factor solution summarizing the highly correlated factors General −/ Physical Fatigue/ Reduced Activity (GF/ PF/ RA) (t2/ t3, CFI = .878/ .896, TLI = .846/ .869, RMSEA = .089/ .085, 90% Confidence Interval .073–.104/ .066–.104). The MFI-total score significantly correlated with the health-related quality of life (range: −.65-(−).66) and the diagnosis of major depression (range: .27–.37). Conclusions In the present sample of CCI patients, a reliable and valid factor structure of the MFI-20 could not be ascertained. Especially the subscale RM should be revised. Since the factors GF, PF and RA cannot be separated from each other and the unclear factorial structure in the present sample of CCI patients, the MFI-20 is not recommended for use in this context.

19	Eine multidimensionale Methodik zur Analyse von Bekehrungsmotiven = A multi-dimensional methodology for the analysis of conversion motives Rink, Tobias 28 February 2006 (has links) Zusammenfassung Das Forschungsprojekt untersucht Bekehrungsmotive von südsudanesischen Migranten, die in einem islamischen Kontext leben. Dazu wird zunächst das biblisch-theologische Bekeh¬rungsverständnis erhoben und im Kontext seiner kirchengeschichtlichen Entwicklung dar¬gestellt. Da jede Bekehrung ein multidimensionaler Prozess ist, der neben theologischen Fragestellungen auch soziologische, anthropologische und religionspsychologische Aspekte enthält, wird ein multidimensionaler Ansatz zur Erforschung von Bekehrungsmotiven konzipiert und ein Forschungswerkzeug erstellt, dass den Kontext südsudanesischer Migranten aufnimmt. Dieses kommt im Rahmen einer Pilotstudie zum Einsatz, die aus fünf Konvertiten-Interviews besteht. Zuerst wird der Inhalt jedes Interviews aus theologischer, soziologischer, religionspsychologischer und anthropologischer Sicht separat erhoben. Danach werden die unterschiedlichen Betrachtungsweisen in einen kritischen Dialog gebracht, um die Bekehrungsmotive zu bestimmen, welche den Kategorien kognitiv-religiös, mystisch-religiös, affektiv, experimentell oder sozial-politisch zugeordnet werden. Zum Schluss wird der Ertrag aller Interviews zu einem Gesamtergebnis verbunden und einer selbstkritischen Evaluierung unterzogen. Summary This dissertation examines conversion motives of Southern Sudanese migrants who live in an Islamic context. First of all a theological view of conversion in scripture and its development in the church history is presented. Since every conversion is a multi-dimensional process containing not only theological problems but also sociological, anthropological and religio¬psychlogical aspects, a multi-dimensional approach and a reseach methodology are designed for above context. This methodology is used for a pilot study of five interviews with converts. Each interview is examined separately from a theological, sociological, religio-psychological and anthropological analysis. After this the different views are brought into a critical dialog in order to identify the motives of conversion which are related to cognitive-religious, mystical¬religious, affective, experimental or social-political categories. The results of all individual interviews are merged in a final analysis and reflected in a self-critical evaluation. / Christian Spirituality, Church History and Missiology / M. Th.
