Memoria para optar al título de Geólogo / La isla Robinson Crusoe (UTM 17H 699754 m E, 6275490 m N) corresponde a relictos de un complejo volcánico de intraplaca perteneciente a la Dorsal de Juan Fernández, un ridge asísmico de orientación aproximada E-W ubicado en la placa de Nazca. Se compone principalmente por secuencias basálticas, escasos niveles sedimentarios y un intrusivo félsico. Este cuerpo denominado Intrusivo Punta Larga (IPL) aflora en la península suroccidental de la isla (UTM 17H 693961.98 m E, 6274247.52 m S) y comprende una anomalía magmática dentro del complejo volcánico. En el presente estudio, se realiza un estudio petrográfico y geoquímico del IPL, que junto a un análisis de geocronología U-Pb en circones y termocronología U-Th/He en apatitos busca interpretar petrogenéticamente este cuerpo, junto con entregar tasas de erosión a largo plazo, para así comprender el significado del IPL dentro de la evolución geológica de la isla Robinson Crusoe. El Intrusivo Punta Larga corresponde a un conjunto de afloramientos discretos de rocas ígneas intrusivas clasificado como sienitas de clinopiroxeno. Se compone de cristales de plagioclasa ricas en calcio con bordes recrecidos de plagioclasa sódica y fracturas con relleno de ortoclasa, además de ortoclasa, clinopiroxeno y menor cuarzo. La roca albergadora corresponde a la Secuencia Punta Larga, unidad volcánica más antigua presente en la isla Robinson Crusoe. Es cogenético con la etapa de volcanismo tipo escudo presente en la isla y su proceso petrogenético dominante corresponde a una cristalización fraccionada de plagioclasa cálcica y clinopiroxeno, influenciada por un proceso de fraccionamiento de olivino y en menor medida de óxidos de Fe-Ti y apatito en los estadíos tempranos del sistema magmático El análisis conjunto de edades U/Pb en circones y U-Th/He en apatito indica que este cuerpo se cristaliza hace aproximadamente 3.8 Ma, emplazándose de forma somera a una profundidad entre 1.425-1.9 km aproximadamente, dentro o levemente por debajo de la zona de retención parcial del He para el sistema U-Th/He en cristales de apatito. Se infiere una tasa de erosión mínima con un rango entre 0.375-0.5 Km/Ma.

The background to this report is the author’s ambition to understand individuals’ work situation, how it’s formed in interaction between the individual and factors in the work-setting. Such an ambition is well in line with the concept of Human-Technology-Organization (HTO), a cross-scientific approach that puts a system-oriented perspective on how human, technolog-ical and organizational factors interact within work systems. The aim of this report was to explore managers’ work-situation and generate an understanding of it from an HTO-perspective by using an organizational model as a framework for an interview guide and to analyze the work situation from an HTO-perspective following the ques-tions at issue: 1. How does the managers experience their work situation? 2. How can an HTO-perspective contribute to the understanding and potential of im-provement of the work situation? The organizational model used in the report is Porras & Robertson’s (1992) "Factors constituting the organizational work setting". The model summarizes and describes the organiza-tional, social, physical and technological factors that up until 1992 had been identified by contemporary research within the "Organizational Development" field as important for organizational change. Four managers’ work situation was studied at the company Södra Cell Mörrum. The report’s methodological approach is of an explorative qualitative nature and has been conducted by the design of an interview guide based on the organizational model described above and semi structured interviews to explore the managers’ work situation. The results give a detailed description of how the managers experience their work situation och how it is affected by the interaction of the factors human-technlogy-organization. In analysis, it’s illustrated how: - the organization’s strategies and structure in interaction with the work flow and tech-nology contributes to the managers’ exposure of stress in their work-situation. - the organizational structure interacts with the individual and vice versa, how the managers’ fuzzy work-description contributes to how they themselves in interaction with other parts of the organization define it and creates informal organizational structure an interaction processes. - the use of technology is affected by its design, by how the organization reinforces its use and by individual characteristics. It has been shown how technology affects the organization’s strategical effort and disposition. - organizational factors such as goals and reward systems interacts with and affect behaviors at the workplace. The analysis also shows how informal aspects of the organization, such as it’s history and culture affects behaviors. The conclusions of the report are: -that an HTO-perspective is a suitable approach to create a broad understanding of the factors which interaction affects work systems. Such an understanding constitutes a good starting point for development and improvement of work systems. - that the result encourages further use and development of the methodological approach of using Porras & Robertsons’ model as a framework for an understanding of the individuals’ work situation. / Bakgrunden till examensarbetet är författarens ambition att förstå människors arbetssituation, hur den skapas i samspel mellan individen och faktorer i dennes arbetsmiljö. En sådan ambition ligger väl i linje med MTO (människa-teknik-organisation), ett tvärvetenskapligt koncept som anlägger ett systemperspektiv på hur mänskliga, tekniska och organisatoriska faktorer interagerar i arbetssystem. Syftet med examensarbetet var att undersöka chefers arbetssituation och skapa förståelse för den ur ett MTO-perspektiv genom att använda en organisationsmodell som grund för en intervjuguide samt att analysera arbetssituationen ur ett MTO-perspektiv utifrån följande frågeställningar: 1. Hur upplever cheferna sin arbetssituation? 2. Hur kan ett MTO-perspektiv öka förståelsen för och förbättringspotentialen i arbetssituationen? Den organisationsmodell som använts är Porras & Robertsons (1992) "Factors constituting the organizational work setting" Modellen sammanfattar och beskriver de organisatoriska, sociala, fysiska och tekniska faktorer som fram till 1992 hade identifierats av befintlig forskning inom "Organizational development" som viktiga för organisationsförändring. Fyra chefers arbetssituation studerades på företaget Södra Cell Mörrum. Metodansatsen för studien är av explorativ kvalitativ karaktär och har genomförts genom utformandet av en intervjuguide baserad på ovan nämnda organisationsmodell samt semistrukturerade intervjuer för att undersöka chefernas arbetssituation. Resultaten ger en utförlig beskrivning av hur cheferna upplever sin arbetssituation och hur den påverkas av interaktionen mellan systemkomponenterna människa-teknik-organisation. I analyser åskådliggörs hur: – organisationens strategier och struktur i interaktion med arbetsflödet och tekniken bidrar till att cheferna exponeras för stress i sin arbetssituation. – organisationsstrukturen samspelar med människan och vice versa, hur chefernas otydliga befattningsbeskrivning bidrar till att de själva i samspel med andra delar av organisationen utformar den och skapar en informell organisationsstruktur och interaktionsprocesser. – användandet av teknik påverkas av hur tekniken är utformad, hur organisationen förstärker användandet och av individuella egenskaper hos människan. Det åskådliggörs hur tekniken påverkar organisationens strategiska arbete och disposition. – organisatoriska faktorer som mål och incitamentssystem interagerar och påverkar beteenden på arbetsplatsen. Analysen påvisar också hur informella sidor av organisationen, som historia och kultur påverkar beteenden. Slutsatserna för examensarbetet är: – att ett MTO-perspektiv är ett lämpligt angreppssätt för att skapa en bred förståelse för de faktorer vars samspel påverkar arbetssystem. En sådan förståelse utgör en god plattform att utgå ifrån vid utveckling och förbättring av arbetssystem. – att resultatet uppmuntrar till en vidare användning och utveckling av metodansatsen att använda Porras & Robertsons modell som grund för förståelse av medarbetares arbetssituation.

The purpose of the present study is to ascertain the principles of poetry to which Robinson adhers, to determine his position in relation to the imagists, and to discuss in some detail the technical qualities of his shorter poems.

Mountain Mission School of Grundy, Virginia, founded by Samuel Robinson Hurley in 1921, is an anomaly of the mission school era of 1880 to 1940. Unlike other mission schools, Mountain Mission School was independent from its inception and was founded by a self-taught, self-made millionaire from southwest Virginia. The school's purpose to "reclaim" the child from material and spiritual poverty lay in Hurley's desire to develop a child's mind, body, and soul through a Christian, industrial education. Through personal commitment to the school and tireless fund-raising efforts for the school, he inspired others to continue the mission he began. Primary sources from Radford University, Milligan College, and Mountain Mission School, plus contemporary articles published in the Christian Standard, defend these claims.

It is the purpose of this study to explore several of Edwin Arlington Robinson’s poems in order to show the poet’s force of language and prosody and to reveal as much as possible his total poetic artistry. The poems are representative of his familiar, shorter Tilbury Town portraits and are taken from his early, middle, and late periods. An honest appraisal will be made to determine the true worth of the poetry, and an attempt will be made to show that Edwin Arlington Robinson deserves a respected position in modern American letters.

In this essay, I examine the role of material culture in Marilynne Robinson's novel Housekeeping (1980) to understand how the prominent presence of material culture introduces complex questions about the relationships among objects, reality, and the self. By recognizing objects' fluidity of meaning, Housekeeping offers its characters a way to see their individuality and conceptions of reality in a similar state of flux. Significantly, it is in the act of recognizing that the socially accepted uses of objects are not necessarily "natural" parts of existence, and, like elements of the natural world, the meanings and uses of these items are susceptible to change and decay that an individual is able to recognize that the self is similarly fluid and moldable, which creates room for both imagination and for the possibility of change.

Thermalization is ubiquitous to all physical systems and is an essential assumption for the postulates of statistical mechanics. Generally, every system evolves under its own dynamics and reaches thermal equilibrium. In the quantum realm, thermal equilibrium is described by the Eigenstate Thermalization Hypothesis (ETH); hence every system that thermalizes is expected to follow ETH. Moreover, the thermalization process is always manifested as transport of matter and quantum information across the system. Thermalizing quantum systems with local interactions are expected to show diffusive transport of global conserved quantities and ballistic information spreading. The vast majority of many-body systems show the typical behavior described above. In this thesis, we study two mechanisms that break the standard picture of quantum thermalization. On the one hand, information spreading may be faster in the presence of long-range interactions. By simulating the Lieb-Robinson bounds in a spin chain with power-law decaying interactions, we distinguish the regime where the long-range character of the interactions becomes irrelevant for information spreading. On the other hand, the interplay of disorder and interactions can slow down transport, entering a sub-diffusive regime. We study this dynamical regime in an Anderson model on random regular graphs, where the emergence of a sub-diffusive regime before the localization transition is highly debated. Looking at long-range spectral correlations, we found that the sub-diffusive regime may be extended over the whole thermal phase of the model. Moreover, when disorder is strong enough, quantum many-body systems can undergo an ergodicity breaking transition to a many-body localized (MBL) phase. These systems do not follow ETH, so they present a challenge for conventional statistical mechanics. In particular, we study how the structure of local operator eigenstate matrix elements (central assumption of ETH) change between the thermal and MBL phase. A complete characterization of matrix elements of correlation functions is achieved via strong disorder quasi-degenerate perturbation theory. Furthermore, we study the MBL transition mechanism, which is still an open question due to the limitations of the available techniques for addressing that regime. Focusing on the avalanche mechanism, we simulate MBL spin chains coupled to a finite and infinite thermal bath. We could estimate the thermalization rate, which behaves as an order parameter and provide bounds for the actual critical disorder in the thermodynamic limit. We propose the existence of an intermediate MBL ``regime' where the system is slowly de-localizing, but relevant time scales are out-of-reach for current experiments and numerical simulations.

Scholars today deem Robinson Crusoe the first British novel. Defoe's construction of Crusoe as the atypical British traveler asserts his collective subjectivity within the framework of intimate personal experiences, accentuating his individualism. Yet, as scholars of Orientalism and Transatlantic theory can attest, calling Robinson Crusoe the first novel provides problematic methodologies that arise from affiliating the novel form to a structure associated the British colonialism and fashioning a "superior" British subject. In this essay, I work to emphasize the hybridity present within the novel, utilize historical context to provide a voice to marginalized Indigenous Americans to show how the format relies upon a relationship between collectivism and individualism, assert Indigenous voices matter in the novel, and analyze the relationship of a new collectivism that arises from narratives that cross into American spaces.
