Seu "emplacement" deu-se no Cretácio Superior, em terrenos granito-gnássicos do Complexo Basal Goiano (Almeida, 1967). Tem forma ovalada com cerca de 60 Km2 de área e eixo maior orientado na direção NS. Situa-se no sudoeste do estado de Goiás - Brasil, a 15°14' de latitude S e 51º16' de longitude W. Possui uma estrutura zonada com núcleo dunítico aureolado por faixas irregulares e descontinuas de peridotitos e piroxenitos, com missouritos e malignitos associados. Ocorrem ainda associados: leucita peridotitos e piroxenitos, mica peridotitos, lamprófiros, fonólitos e essexitos. Os dunitos perfazem quase 3/4 da área total de afloramento do complexo. Foram definidas 3(três) associações petrográficas, a saber: associação de rochas ultramáficas normais - constituída por dunitos, peridotitos e piroxenitos; associação de rochas ultramáficas alcalinas: constituída por missouritos, leucita peridoti tos e piroxenitos; e associação de rochas máficas feldspatoidais - constituída por malignitos e essexitos. Do ponto de vista mineralógico o complexo é caracterizado pela presença de minerais deficientes em silica: olivina, leucita e nefelina; pela associação olivina - clinopiroxênio e pela ausência de ortopiroxênio. Olivina e clinopiroxênic ocorrem, quase sempre, como cristais quimicamente homogêneos, exibem porém, variações composicionais de uma rocha para outra. A olivina passa de Fo88.2 em dunitos, para Fo80.5 em clinopiroxenitos. O clinopiro xênio mostra variações composicionais num campo restrito que engloba os limites diopsidio/salita. Cristais inomogêneos, zonados, o correm apenas em rochas alcalinas, onde foram registradas variações de Fo80.1 para Fo66.81 na olivina e de Na40.56 para Na23.59 no plagioclãsio. Foram caracterizadas texturas de "cumulus" e processos de diferenciação fracionada. Diagramas de variação mostram um "trend" para as rochas ultramáficas normais e outro para aqueles de afinidade alcalina. O complexo de Santa Fé é comparável àqueles do Grupo Iporé (Goiás), ao de Emigrant Gap (Califórnia) e ao de Union Bay (Alaska). A ausência de gabros a dois piróxénios e a associação de rochas alcalinas distinguem-no dos complexos concéntricos de Jackson e Thayer (1972). Concluiu-se por um magma original de natureza ultra máfica, submetido a "emplacement", cristalização e, diferenciação fracionada. Contaminações locais durante o processo de ascensão podem ter sido responsáveis pela geração de fusões parciais, potássinas.

La maladie de Parkinson est une maladie neurodégénérative secondaire à la mort des neurones dopaminergiques, entraînant un dysfonctionnement des ganglions de la base (GB), ensemble de noyaux sous corticaux impliqués dans le contrôle de la motricité. Les symptômes moteurs sont améliorés par le traitement dopaminergique et par la stimulation cérébrale profonde (SCP) du noyau subthalamique (NST). Il a été montré que le changement d’activité bêta est corrélé avec l’amélioration motrice des symptômes de bradykinésie et rigidité. L’hypothèse serait que les oscillations bêta pourraient être un physiomarqueur spécifique des symptômes moteurs de la MP. L’objectif de cette thèse est de comprendre l’activité du NST et de trouver un physiomarqueur de la MP : au repos et pendant un paradigme Go/Nogo.Dans une première partie, pour 55 patients, nous avons modélisé la puissance avec un modèle linéaire à effets mixtes dans six bandes de fréquences selon la position des électrodes, la présence de complications liées au traitement dopaminergique, de la sévérité des symptômes, et du changement de ces symptômes suite à la prise du traitement dopaminergique. Le changement le plus important entre OFF- et ON-DOPA est observé dans la bande low-bêta. Cependant, nous n’avons pas trouvé de corrélation entre la sévérité de la bradykinésie, rigidité, ou du score axial avec l’activité low-bêta. Mais, nous avons trouvé que la sévérité de la rigidité était associée aux fréquences supérieures à 20Hz. Nous avons également trouvé une corrélation positive entre la sévérité du tremblement dans toutes les bandes de fréquences, qui est très importante pour la bande thêta. Etonnement, nous avons trouvé que les complications liées au traitement dopaminergique pouvaient induire des informations dans toutes les bandes. Cet effet est très important pour la bande thêta. Nos résultats au repos suggèrent que l’activité bêta n’est pas le physiomarqueur idéal de la MP.Pendant le paradigme Go/Nogo, pour 15 patients, nous avons modélisé la puissance avec un modèle linéaire à effets mixtes pour toutes les fréquences selon la position des électrodes, la sévérité des symptômes, les données comportementales et cinétiques. Nous avons trouvé une spécificité temporelle et spatiale des activités du NST au cours du paradigme. Nos résultats montrent que le NST est impliqué dans le contrôle des différentes étapes du mouvement volontaire du membre supérieur et que le défaut de dopamine dans le circuit sensorimoteur des GB génère une série de changements oscillatoires au sein du NST lors du mouvement. Cependant, l'activité thêta est apparue comme une activité caractéristique en OFF-DOPA fortement corrélée aux paramètres comportementaux et cinétiques. Cette activité pourrait être le physiomarqueur de la MP pendant l'exécution d'un mouvement, son augmentation pourrait induire une réponse motrice et un mouvement rapide. / The Parkinson's disease is a secondary neurodegenerative disease in the death of the dopaminergic neurons, pulling a dysfunction of the ganglions of the base (GB), the set pits under cortical implied in the control of the motricity...

Around 1900 an interest towards non-Christian spirituality could be observed in Swedish society. There have been studies in spirituality, but little attention has been given in considering the circulation and transcultural exchange of knowledge production. The aim of this thesis is to show how knowledge of alternative spiritualty was constructed by the press’ description of encounters between spiritual go-betweens from India and America and the Swedish public between 1899 and 1926. By studying articles from daily papers, I propose that actors from diverse cultures, Swedish institutional arenas, and the public had a crucial part in the knowledge production of alternative spirituality. I argue that in the process of circulating and reformulating knowledge, a narrative was created: a mediation of alternative spirituality, custom-made and conducive for the Western audiences and their needs.

Background: The development of an objective and comprehensive drug-based index of physical function for older adults has the potential to more accurately predict fall risk. Design: the index was developed using 862 adults (ages 57–85) from the National Social Life, Health, and Aging Project (NSHAP) Wave 1 study. The index was evaluated in 70 adults (ages 51–88) from a rehabilitation study of dizziness and balance. Methods: The prevalence among 601 drugs for 1,694 side effects was used with fall history to determine the magnitude of each side effect's contribution towards physical function. This information was used to calculate a Medication-based Index of Physical function (MedIP) score for each individual based on his or her medication profile. The MedIP was compared to the timed up and go (TUG) test as well as drug counts using receiver operating characteristic (ROC) analysis. The associations between various indices of physical function and MedIP were calculated. Results: Within the NSHAP data set, the MedIP was better than drug counts or TUG at predicting falls based on ROC analysis. Using scores above and below the cutpoint, the MedIP was a significant predictor of falls (OR = 2.61 [95% CI 1.83, 3.64]; P < 0.001). Using an external data set, it was shown that the MedIP was significantly correlated with fall number (P = 0.044), composite physical function (P = 0.026) and preferred gait speed (P = 0.043).

隨著廣播、電信、網路的匯流與數位科技發展，消費者在手機上隨時隨地接受「到處存在」（ubiquitous）的電視服務時代已來臨。2003年，第三代行動通訊系統（The Third Generation，3G）服務在台灣正式推行，2009年2月底3G用戶數首度超越2G，使得3G用戶數佔全行動電話用戶數的一半以上。台灣的3G市場及3G用戶數正繼續成長，不過，卻出現許多3G用戶未(曾)使用3G服務的現象，值得關注。 因此，本研究以使用者角度出發，以Palmgreen與Rayburn的GS-GO模式為主軸，探討目前3G服務使用者跟曾使用3G服務者、3G服務非使用者的追求滿足（GS）。另外，也探討目前3G服務使用者，與曾使用3G服務者的獲得滿足（GO），以及此兩者的GS與GO差異及相關性；並討論此差異是否動搖使用者原始信念，並對後續行為產生影響。還有，目前3G服務使用者與曾使用3G服務者，其滿意度差異為何。進一步，本論文還以Rogers的「創新傳佈理論」，加以比較目前3G服務使用者、曾使用3G服務者，與3G服務非使用者之間的創行特質為何。 本研究選定《i.Q線上問卷調查網》會員作為研究樣本，進行電子郵件的網路問卷調查。研究結論如下： 一、探討目前3G服務使用者、曾使用3G服務者及3G服務非使用者的GS因素部分，本研究結果獲得：以下的GS因素中，三者皆相同，且依序為便利追求、娛樂追求、資訊追求、個人化、社會性、時髦性，以及價格因素。然而，三者在GS因素中，時髦因素無差異，其餘因素則都有差異。而目前3G服務使用者與曾使用3G服務者的GO因素中，三者亦相同，依序為便利追求、娛樂追求、資訊追求、個人化、社會性、時髦性，以及價格因素。然而，兩者間的GO因素中，資訊追求顯示有差異，其他GO因素則沒有差異。 二、探討目前3G服務使用者與曾使用3G服務者的追求滿足（GS）、獲得滿足（GO）差異，與相關性部分，據本研究推論：滿意程度會影響後續使用3G手機服務與否，然而，不滿意程度不會影響後續使用3G使用服務與否。 三、探討創新特質部分：目前3G服務使用者與曾使用3G服務者的兩者間，其創新性並不影響使用3G服務與否。然而，目前3G服務使用者與3G服務非使用者兩者間的創新性差異，則會影響3G服務的使用。此外，創新性差異與各項GS因素的分析結果皆呈現顯著性，其中，又與GS因素中的時髦性因素產生最高度相關。

It is essential to consider what new technologies mean to the people who use them and the ways in which they are experienced and used. In the context of public transit services in Saskatoon, understanding what the recent changes from a manual to an electronic/automated system means to users and the broader community is critically important to the overall assessment of the service. Investigating users’ lived experiences and interpretations of technical artifacts is valuable to understanding socio-technical relations or the embodied interactions of humans and machines as “technologies-in-practice.” Research into socio-technical relations has primarily focused on large scale technological systems and expert practices while less attention has been paid to “seemingly mundane” technologies or technical artifacts routinely used in everyday life. At the same time, this preoccupation has overshadowed or downplayed the importance of exploring users’ experiences and interpretations of technologies. The goal of this research is to contribute to the sociological understanding of mundane technologies-in-practice and socio-technical relations more broadly. In order to gain insight into this relationship, this thesis focuses on bus riders’ (users) and the community’s perceptions of the Go-Pass smartcard and electronic fare system used by the public transit service in Saskatoon. The perspectives of Go-Pass users and community stakeholders (n=15) were investigated using qualitative semi-structured interviews to gain deeper understanding into the complex relationship between users and technologies. Drawing from Science and Technology Studies (STS) and the sociology of technology literature, I propose that a sociomaterial theoretical perspective following a mutual shaping framework offers insight into socio-technical relations. Both critical and feminist technology studies literature has been helpful for developing an understanding of the wider social and political contexts of technical use which underscores this study. In particular, the conceptual insights of “socio-technical assemblages” (Suchman, 2007) and “intra-action” (Barad, 2003) have been helpful tools for exploring agency, subjectivity and power which is key to uncovering the intricacies of socio-technical relations and human-machine interaction. The four main themes emerging from this study were: 1) shifting human-machine roles and relationships; 2) the socio-technical construction of the bus rider; 3) configuring users’ and technologies; and 4) structural issues and social justice implications of technologies-in-practice. The findings demonstrate that the use of this new system is mutually co-constructed by both social and technical factors whereby both the users and the technology inform perceptions and use. There was also the unexpected connection between users’ everyday situated uses, experiences and interpretations of the Go-Pass technologies to wider social-political contexts. There were a number of issues raised in relation to the implementation of the Go-Pass system which had negative effects or unintended social and technical consequences particularly for those most marginalized economically. At the same time, there were important benefits and positive effects on riders’ quality of life and use of the service. Finally, participants’ perspectives have contributed to understanding what the Go-Pass technologies mean to them, the ways in which they are used in practice and the ways in which the mixing of people and seemingly mundane technologies shape relations in everyday settings.

Vitamin D deficiency and insufficiency are now seen as a contemporary health problem in Australia with possible widespread health effects not limited to bone health1. Despite this, the Vitamin D status (measured as serum 25-hydroxyvitamin D (25(OH)D)) of ambulatory adults has been overlooked in this country. Serum 25(OH)D status is especially important among this group as studies have shown a link between Vitamin D and fall risk in older adults2. Limited data also exists on the contributions of sun exposure via ultraviolet radiation and dietary intake to serum 25(OH)D status in this population. The aims of this project were to assess the serum 25(OH)D status of a group of older ambulatory adults in South East Queensland, to assess the association between their serum 25(OH)D status and functional measures as possible indicators of fall risk, obtain data on the sources of Vitamin D in this population and assess whether this intake was related to serum 25(OH)D status and describe sun protection and exposure behaviors in this group and investigate whether a relationship existed between these and serum 25(OH)D status. The collection of this data assists in addressing key gaps identified in the literature with regard to this population group and their Vitamin D status in Australia. A representative convenience sample of participants (N=47) over 55 years of age was recruited for this cross-sectional, exploratory study which was undertaken in December 2007 in south-east Queensland (Brisbane and Sunshine coast). Participants were required to complete a sun exposure questionnaire in addition to a Calcium and Vitamin D food frequency questionnaire. Timed up and go and handgrip dynamometry tests were used to examine functional capacity. Serum 25(OH)D status and blood measures of Calcium, Phosphorus and Albumin were determined through blood tests. The Mean and Median serum 25-Hydroxyvitamin D (25(OH)D) for all participants in this study was 85.8nmol/L (Standard Deviation 29.7nmol/L) and 81.0nmol/L (Range 22-158nmol/L), respectively. Analysis at the bivariate level revealed a statistically significant relationship between serum 25(OH)D status and location, with participants living on the Sunshine Coast having a mean serum 25(OH)D status 21.3nmol/L higher than participants living in Brisbane (p=0.014). While at the descriptive level there was an apparent trend towards higher outdoor exposure and increasing levels of serum 25(OH)D, no statistically significant associations between the sun measures of outdoor exposure, sun protection behaviors and phenotypic characteristics and serum 25(OH)D status were observed. Intake of both Calcium and Vitamin D was low in this sample with sixty-eight (68%) of participants not meeting the Estimated Average Requirements (EAR) for Calcium (Median=771.0mg; Range=218.0-2616.0mg), while eighty-seven (87%) did not meet the Adequate Intake for Vitamin D (Median=4.46ug; Range=0.13-30.0ug). This raises the question of how realistic meeting the new Adequate Intakes for Vitamin D is, when there is such a low level of Vitamin D fortification in this country. However, participants meeting the Adequate Intake (AI) for Vitamin D were observed to have a significantly higher serum 25(OH)D status compared to those not meeting the AI for Vitamin D (p=0.036), showing that meeting the AI for Vitamin D may play a significant role in determining Vitamin D status in this population. By stratifying our data by categories of outdoor exposure time, a trend was observed between increased importance of Vitamin D dietary intake as a possible determinant of serum 25(OH)D status in participants with lower outdoor exposures. While a trend towards higher Timed Up and Go scores in participants with higher 25(OH) D status was seen, this was only significant for females (p=0.014). Handgrip strength showed statistically significant association with serum 25(OH)D status. The high serum 25(OH)D status in our sample almost certainly explains the limited relationship between functional measures and serum 25(OH)D. However, the observation of an association between slower Time Up and Go speeds, and lower serum 25(OH)D levels, even with a small sample size, is significant as slower Timed Up and Go speeds have been associated with increased fall risk in older adults3. Multivariable regression analysis revealed Location as the only significant determinant of serum 25(OH)D status at p=0.014, with trends (p=>0.1) for higher serum 25(OH)D being shown for participants that met the AI for Vitamin D and rated themselves as having a higher health status. The results of this exploratory study show that 93.6% of participants had adequate 25(OH)D status-possibly due to measurement being taken in the summer season and the convenience nature of the sample. However, many participants do not meet their dietary Calcium and Vitamin D requirements, which may indicate inadequate intake of these nutrients in older Australians and a higher risk of osteoporosis. The relationship between serum 25(OH)D and functional measures in this population also requires further study, especially in older adults displaying Vitamin D insufficiency or deficiency.
