The Simpson Mountains have long been of economic interest and have renewed interest in their potential value. Field mapping of the project area redefined structural relationships between stratigraphic units. Geometric and kinematic analysis of structures in the Simpson Mountains show the range is deformed by the three most recent tectonic events: the Sevier Orogeny, the Laramide Orogeny, and Basin and Range Extension. Laramide structures define the range with a significant E-W normal fault and an E-W thrust fault, which are both likely related to Eocene-age igneous intrusions. Principal component analysis (PCA) of regional quartzite X-ray Fluorescence (XRF) data resulted in distinctive populations between the Eureka Quartzite and the Mutual and Prospect Mountain Quartzites. The PCA was paired with petrographic analysis of regional quartzites where samples were diagnostically classified to help validate the PCA results. XRF analysis of volcanic rocks show volcanic arc origin. 40Ar/39Ar dating of the volcanic rocks associated with the intrusions yield new ages of 34.09±0.10 to 37.05±0.06 Ma and 19.11±0.02 to 19.18±0.03. Lithostratigraphy of the map area was validated by identification of fossil samples. The Eocene intrusions are likely sources of mineralization in the range along older Sevier structures.

Abstract Software process assessment and improvement came under the spotlight in the discussion of software engineering when the Software Engineering Institute published the maturity model for software process capability determination in 1987. Since then, several new approaches and standards have been developed. This thesis introduces a European software process assessment and improvement methodology called BOOTSTRAP, which was initially developed in an ESPRIT project starting from lean and kaizen philosophy. The focus is on the evolution of methodology and how it was developed, using an experimental research approach. The work covers also enhancements to the methodology investigated in the SPICE, PROFES and TAPISTRY projects. The enhancements expand the original methodology into new specific application areas, keep it compliant with new quality standards and certification, improve the efficiency of the assessment method, enhance the focus from process to product and strengthen improvement monitoring and support. To address these areas, the new BOOTSTRAP methodology releases offer tailored and enhanced assessment reference models and enhanced assessment and improvement methods. The new features also facilitate more frequent and even continuous assessments with software measurement-based indicators. The thesis explains the origin and features of BOOTSTRAP software process assessment and improvement methodology and how it was developed for professional use. The discussion starts with the evolution of the methodology. Then the new trends and demands are introduced and new features of the BOOTSTRAP methodology described. The conclusion discusses how the methodology developed to be able successfully to support professional software process assessment, to align it with the evolution of software engineering, to adopt the features and requirements of the underlying standards in order to conform to the requirements set by ISO 15504 standard and to become validated in practice. / Tiivistelmä Ohjelmistoprosessin arvioinnista ja parantamisesta tuli ohjelmistotekniikan keskeinen kiinnostuksen kohde kun Carnegie-Mellon yliopiston ohjelmistotekniikan instituutti SEI julkaisi kypsyysmallinsa ohjelmistoprosessin kyvykkyyden arviointiin vuonna 1987. Siitä lähtien maailmalla on syntynyt lukuisa määrä uusia malleja ja standardeja tälle alueelle. Tässä väitöskirjassa esitellään eurooppalainen ohjelmistoprosessin arviointi- ja parantamismenetelmä BOOTSTRAP, joka kehitettiin alun perin Euroopan unionin ESPRIT tutkimusohjelman rahoittamassa projektissa lähtien japanilaisesta ohut-ajattelusta (Lean) ja sen jatkuvan parantamisen periaatteesta (Kaizen). Esitys keskittyy menetelmän kehittymiseen ja siihen miten menetelmä käytännössä kehitettiin käyttäen kokeellista tutkimustapaa teollisessa ympäristössä. Työ kattaa myös alkuperäiseen menetelmään tehdyt laajennukset, jotka syntyivät yhteistyössä SPICE, PROFES ja TAPISTRY projekteissa tehdyn tutkimuksen tuloksena. Tehdyt laajennukset mahdollistavat menetelmän käytön uusilla sovellusalueilla, takaavat menetelmän yhteensopivuuden alan laatu- ja sertifiointistandardien kanssa, parantavat menetelmän tehokkuutta, laajentavat menetelmän käyttöaluetta prosessin arvioinnista sisältämään myös tuotteen kehittämisen arvioinnin ja vahvistavat parantamisen seurantaa ja tukemista. Toteuttaakseen näiden uusien ominaisuuksien vaatimukset uudet BOOTSTRAP menetelmän julkistukset tarjoavat räätälöityjä ja laajennettuja mallikuvauksia arviointien tekemiseksi sekä entistä täydellisempiä lähestymistapoja arviointien suorittamiselle ja parantamiselle. Menetelmän uudet ominaisuudet mahdollistavat myös usein toistuvien arviointien suorittamisen ja jopa jatkuvan arvioinnin ohjelmisto-mittauksia hyödyntäen. Väitöskirjassa kuvataan yksityiskohtaisesti BOOTSTRAP menetelmän lähtö-kohdat ja ominaisuudet ja se kuinka menetelmä onnistuttiin kehittämään ammattimaiseen ohjelmistoprosessin arviointiin ja parantamiseen sopivaksi. Ensin kuvataan menetelmän kehittyminen ja sitten edetään alan uusien kehitystrendien ja vaatimusten esittelyyn siihen kuinka BOOTSTRAP menetelmä uudet ominaisuudet vastaavat näihin vaatimuksiin. Yhteenvedossa osoitetaan kuinka kehittämisessä onnistuttiin saamaan aikaan uusi menetelmä, joka sopii ammattimaiseen ohjelmistoprosessin arviointiin, vastaa kaikilta osin alan kehittymisen vaatimuksia, sisältää alan standardien vaatimukset täyttävät käytännössä koestetut ominaisuudet, jotka takaavat menetelmän vastaavuuden ISO 15504 standardin vaatimuksiin.

The life and career of Albert Wicker, Jr. (1869-1928), reflects the growth of the new urban African-American middle class in New Orleans, Louisiana, in the early years of the twentieth century. He spent his career working for advances in education while using memberships in churches, Masonic groups, insurance companies, benevolent societies, and educational leagues to achieve his personal and professional goals. The networks created by him and others along the way illustrate not only complexity of black life in New Orleans but also the growing tendency of differing ethnic groups to work together to achieve common economic, political, social objectives.

At some point during a creative action something clicks, suddenly the prospective problem solver just knows the solution to a problem, and a feeling of joy and relief arises. This phenomenon, called Eureka experience, insight, Aha moment, hunch, epiphany, illumination, or serendipity, has been part of human narrations for thousands of years. It is the moment of a subjective experience, a surprising, and sometimes a life-changing event. In this thesis, I narrow down this moment 1. conceptually, 2. experientially, and 3. temporally. The concept of emerging solutions has a multidisciplinary background in Cognitive Science, Arts, Design, and Engineering. Through the discussion of previous terminology and comparative reviews of historical literature, I identify sources of ambiguity surrounding this phenomenon and suggest unifying terms as the basis for interdisciplinary exploration. Tracking the experience based on qualitative data from 11 creative practitioners, I identify conflicting aspects of existing models of creative production. To bridge this theoretical and disciplinary divide between iterative design thinking and sequential models of creativity, I suggest a novel multi-layered model. Empirical support for this proposal comes from Dira, a computer-based open-ended experimental paradigm. As part of this thesis I developed the task and 40 unique sets of stimuli and response items to collect dynamic measures of the creative process and evade known problems of insightful tasks. Using Dira, I identify the moment when solutions emerge from the number and duration of mouse-interactions with the on-screen elements and the 124 participants' self-reports. I provide an argument for the multi-layered model to explain a discrepancy between the timing observed in Dira and existing sequential models. Furthermore, I suggest that Eureka moments can be assessed on more than a dichotomous scale, as the empirical data from interviews and Dira demonstrates for this rich human experience. I conclude that the research on insight benefits from an interdisciplinary approach and suggest Dira as an instrument for future studies.
