Living among gods – The Capacocha children : A hermeneutic analysis of the Chakana philosophy / Att leva bland gudar – Capacochabarnen : En hermeneutisk analys av Chakana-filosofin

Ekberg Toscano, Frida January 2023 (has links)
This thesis aims to study the Capacocha, which is an Inca ritual where children were offered to their gods in the sacred places called Huacas (places of origin) and offered artefacts together with the children links to the Inca's sacred symbol, the Chakana, which in turn it is the life philosophy of the Inca culture. This thesis uses this philosophy to understand the phenomenon and the elements that define Huacas and the Capacocha ritual. Furthermore, a hermeneutic approach with phenomenology and phenomenology of landscape theory is applied to understand the symbolism and meaning from the Inca's cultural perspective. For this thesis, three specific case studies are analysed: the children from Llullaillaco, Chuscha and Cerro El Plomo, all situated at high altitudes (5200 - 6739 m) in the Andes. These selected places by the Incas were Huacas. The analysis is built on a comprehensive study of the cultural value and the symbolic meaning of the Capacocha ritual in relation to the Huacas and the Incas' perspective (Chakana) since previous studies concerning the Capacocha ritual, and Huacas did not consider the Chakana philosophy in their interpretations. The aim is to narrow the gap in understanding the Inca worldview to contribute with academic knowledge and understanding of the phenomenon that defines Huacas and the Capacocha ritual from the Incas' perspective. The study shows that the Incas had a holistic perspective where everything is entangled through time and space, and this demonstrates that the children were not just offered to the Inca gods. Instead, the children lived among the gods because they became gods through the Capacocha ritual, a transformation process. / Denna uppsats syftar till att studera Inkaritualen Capacocha, där barn offrades tillsammans med andra offergåvor till sina gudar på de heliga platserna som kallas Huacas (ursprungsplatser) och barnen och offergåvorna hänger samman med Inkafolkets heliga symbol, Chakana, som är inkakulturens livsfilosofi. Denna studie använder denna filosofi för att förstå fenomenet och de element som definierar Huacas och Capacocha-ritualen. Vidare tillämpas ett hermeneutiskt förhållningssätt med fenomenologi och fenomenologi inom landskapsteorin för att förstå symboliken och innebörden ur inkafolkets kulturella perspektiv. I denna uppsats analyseras tre specifika fallstudier: barnen från Llullaillaco, Chuscha och Cerro El Plomo och alla är belägna på hög höjd (5200 - 6739 m) i Anderna. Dessa utvalda platser av inkafolket var Huacas. Analysen bygger på en omfattande studie av det kulturella värdet och den symboliska innebörden av Capacocha-ritualen i relation till Huacas och inka perspektivet (Chakana) sedan tidigare studier angående Capacocha-ritualen, och Huacas beaktade inte Chakana-filosofin i sina tolkningar. Syftet är att minska klyftan i förståelsen av inkavärldsbilden för att bidra med akademisk kunskap och förståelse för det fenomen som definierar Huacas och Capacocharitualen ur inkafolkets perspektiv. Studien visar att inkafolket hade ett holistiskt perspektiv där allt är sammanflätat i tid och rum, och detta visar att barnen inte bara offrades till inkagudarna. Istället levde barnen bland gudarna eftersom de själva blev gudar genom Capacocharitualen, som står för en förvandlingsprocess. / Esta tesis tiene como objetivo estudiar el ritual de Capacocha, el cual es un ritual inca donde se ofrecían niños junto con artefactos a sus dioses en los lugares sagrados llamados Huacas (lugares de origen), los cuales estaban vinculados al símbolo sagrado de los Incas, el Chakana, que en a su vez es la filosofía de vida de la cultura Inca. Esta tesis utiliza esta filosofía para comprender el fenómeno y los elementos que definen a las Huacas y el ritual de la Capacocha, aplicando un enfoque hermenéutico con la fenomenología y la fenomenología de la teoría del paisaje para comprender el simbolismo y el significado desde la perspectiva cultural de los incas. Para esta tesis se analizan tres casos de estudio específicos: los niños de Llullaillaco, Chuscha y Cerro El Plomo, todos ellos situados a gran altura (5200 - 6739 m). Estos lugares seleccionados por los Incas fueron las Huacas. El análisis se construye a partir de un estudio integral del valor cultural y el significado simbólico del ritual Capacocha en relación con las Huacas y la perspectiva de los Incas (Chakana). El estudio derivó debido a que estudios previos sobre el ritual Capacocha, y Huacas no consideraron la filosofía Chakana durante sus interpretaciones, lo cual dejó una brecha de entendimiento del ritual y los lugares, ya que el Chakana está conectado al ritual y los lugares, misma que es una filosofía de vida que rige mucho la perspectiva de los Incas. Al ignorar esta filosofía, muchas de las interpretaciones de los estudios previos son incompletas o sesgadas debido a la influencia de la perspectiva occidental. Por ello, el objetivo de mi tesis es acortar la brecha en la comprensión de la cultura Inca y para contribuir con el conocimiento académico y la comprensión del fenómeno que define a Huacas y el ritual Capacocha desde una perspectiva más cercana a su origen, los Incas y el Chakana.   Como resultado, el estudio demostró que los incas tenían una perspectiva holística donde todo se entrelaza a través del tiempo y el espacio, y demostrando que los niños no solo eran ofrecidos a los dioses incas. En cambio, los niños vivieron entre los dioses porque se convirtieron en dioses a través del ritual Capacocha, un proceso de transformación influenciado por la filosofía del Chakana. El resultado, también mostró que la filosofía del Chakana influenció todo el proceso, y que para los Incas, no hubo sacrificios; ellos dieron ofrendas a sus dioses. Y que en realidad, desde su perspectiva, los niños no murieron, sino que tomaron otra forma de vida para formar parte de un vínculo a través de los mundos de los Incas.

Skolans Fostrande Roll En studie kring arbetsmetoden "Bra Val"

Knutsson, Henrik January 2008 (has links)
AbstractKnutsson, Henrik (2008). Skolans Fostrande Roll, En studie kring arbetsmetoden ”Bra Val”School´s Educating Role A survey about the method Making Good Choice Examensarbete 15 högskolepoäng, SÄL 3:2, Lärarutbildningen, Malmö högskolaI min undersökning har jag försökt ta reda på hur eleverna på ett individuellt utformat program i Malmö, uppfattar arbetet med den individuella bedömningen av genomförandet av lektioner som vi kallar Bra Val. Metoden Bra Val har sitt ursprung i trappmodellen, Det är ditt val, hämtat från boken Ordning och reda i skolan, skriven av Edin och Drummond (2006). Arbetet bygger på att lärarens ledarskap skapa förutsättning för en social utveckling i skolan. Tillsammans med arbetet med veckorapporten i Bra Val skall eleven bli varse och lockas till goda val i undervisningen och lära sig stå för de konsekvenser valen innebär. Jag valde att göra en enkätstudie detta för att få ett så neutralt inflytande över svaren som möjligt. Svaren från enkäten har kompletterats med litteratur studier samt möte och samtal med författaren Mats Edin. Resultatet visar att vi har lyckats skapa positiv utvecklings spiraler hos eleverna. Den främsta slutsatsen är att eleverna upplever att de är hjälpt av arbetssättet med Bra Val i undervisningen, eleverna upplever att de aktivt tänker på att göra goda val i undervisningen och att de känner att de lyckas på lektionerna.

Off-resonance correction for magnetic resonance imaging with spiral trajectories

Nylund, Andreas January 2014 (has links)
The procedure of cardiographic magnetic resonance imaging requires patients to hold their breath for up to twenty seconds, creating an uncomfortable situation for many patients. It is proposed that an acquisition scheme using spiral trajectories is preferable due to their much shorter total scan time; however, spiral trajectories suffer from a blurring effect caused by off-resonance frequencies in the image area. There are several methods for reconstructing images with reduced blur and Conjugate Phase Reconstruction has been chosen as a method for implementation into Matlab-script for evaluation in regards to image reconstruction quality and computation time. This method finds a conjugate to the off-resonance from a field map to demodulate the image and an algorithm for frequency‑segmented Conjugate Phase Reconstruction is implemented along with an improvement called Multi-frequency Interpolation. The implementation is tested through simulation of spiral magnetic resonance imaging using a Shepp‑Logan phantom. Different off-resonance frequencies and field maps are used to provide a broad view of the functionality of the code. The two algorithms are then compared to each other in terms of computation speed and image quality. It is concluded that this implementation might reconstruct images well but that further testing on actual scan sequences is required to determine the usefulness. The Multi-frequency Interpolation algorithm yields images that are not useful in a clinical context. Further study of other methods not requiring a field map is suggested for comparison.

Om lärares och elevers motivation

Ivarsson, David, Altervall, Joakim January 2007 (has links)
Altervall, Joakim & Ivarsson, David. (2007) Om lärares och elevers motivation. (On Teachers’ and Pupils’ Motivation). Skolutveckling och ledarskap, Allmänna utbildningsområdet 60 poäng, Lärarutbildningen, Malmö Högskola.Syftet med den här uppsatsen är att ta reda på vad som motiverar lärare och elever och vilka drivkrafter de har för att verka i skolan. Vidare vill vi undersöka hur dessa krafter överensstämmer, skiljer sig åt och hur de samverkar med varandra. Vi har intervjuat sex lärare och sex elever. Dessa intervjuer tolkade vi kvalitativt utifrån ett antal teoretiska perspektiv för att förklara vad som motiverar dessa lärare och elever.Sammanfattningsvis konstaterar vi att lärare och elever motiveras av samma faktorer samt att deras motivation är beroende av varandra. Vi förespråkar att relationen mellan lärare och elever inte bara är professionell utan också har en personlig sida.

Quantitative Assessment Of Software Development Project Management Issues Using Process Simulation With System Dynamics Elements

Mizell, Carolyn 01 January 2006 (has links)
The complexity of software development projects makes estimation and management very difficult. There is a need for improved cost estimation methods and new models of lifecycle processes other than the common waterfall process. This work has developed a new simulation model of the spiral development lifecycle as well as an approach for using simulation for cost and schedule estimation. The goal is to provide a tool that can analyze the effects of a spiral development process as well as a tool that illustrates the difficulties management faces in forecasting budgets at the beginning of a project which may encourage more realistic approaches to budgetary planning. A new discrete event process model of the incremental spiral development lifecycle approach was developed in order to analyze the effects this development approach has on the estimation process as well as cost and schedule for a project. The input data for the key variables of size, productivity, and defect injection rates in the model was based on analysis of Software Engineering Laboratory data and provided for analysis of the effects of uncertainty in early project estimates. The benefits of combining a separate system dynamics model with a discrete event process models was demonstrated as was the effects of turnover on the cost and schedule for a project. This work includes a major case study of a cancelled NASA software development project that experienced cost and schedule problems throughout its history. Analysis was performed using stochastic simulation with derived probability distributions for key software development factors. A system dynamics model of human resource issues was also combined with the process model to more thoroughly analyze the effects of turnover on a project. This research has demonstrated the benefits of using a simulation model when estimating to allow for more realistic budget and schedule determination including an interval estimate to help focus on the uncertainty of early estimates.

On-chip Spiral Inductor/transformer Design And Modeling For Rf Applications

Chen, Ji 01 January 2006 (has links)
Passive components are indispensable in the design and development of microchips for high-frequency applications. Inductors in particular are used frequently in radio frequency (RF) IC's such as low-noise amplifiers and oscillators. High performance inductor has become one of the critical components for voltage controlled oscillator (VCO) design, for its quality factor (Q) value directly affects the VCO phase noise. The optimization of inductor layout can improve its performance, but the improvement is limited by selected technology. Inductor performance is bounded by the thin routing metal and small distance from lossy substrate. On the other hand, the in-accurate inductor modeling further limits the optimization process. The on-chip inductor has been an important research topic since it was first proposed in early 1990's. Significant amount of study has been accomplished and reported in literature; whereas some methods have been used in industry, but not released to public. It is of no doubt that a comprehensive solution is not exist yet. A comprehensive study of previous will be first address. Later author will point out the in-adequacy of skin effect and proximity effect as cause of current crowding in the inductor metal. A model method embedded with new explanation of current crowding is proposed and its applicability in differential inductor and balun is validated. This study leads to a robust optimization routine to improve inductor performance without any addition technology cost and development.
