abstract: This research explores how people's relationships with the spirits of the dead are embedded in political histories. It addresses the ways in which certain spirits were integral "inhabitants" of two social environments with disparate political traditions. Using the prehistoric mortuary record, I investigate the spirits and their involvement in socio-political affairs in the Prehispanic American Southeast and Southwest. Foremost, I construct a framework to characterize particular social identities for the spirits. Ancestors are select, potent beings who are capable of wielding considerable agency. Ancestral spirits are generic beings who are infrequently active among the living and who can exercise agency only in specific contexts. Anonymous groups of spirits are collectives who exercise little to no agency. I then examine the performance of mortuary ritual to recognize these social identities in the archaeological record. Multivariate analyses evaluate how particular ritual actions memorialized the dead. They concentrate on treatment of the body, construction of burial features, inclusion of material accompaniments, and the spaces of ritual action. Each analysis characterizes the social memories that ritual acts shaped for the spirits. When possible, I supplement analysis of archaeological data with ethnohistoric and ethnographic information. Finally, I compile the memories to describe the social identities for the spirits of the dead. In this study, I examine the identities surrounding the spirits in both a Mississippian period settlement on the Georgia coast and in several Protohistoric era Zuni towns in the northern Southwest. Results indicate that ancestors were powerful members of political factions in coastal Mississippian communities. In contrast, ancestral spirits and collectives of long-dead were custodians of group histories in Zuni communities. I contend that these different spirits were rooted in political traditions of competition. Mississippian ancestors were influential agents on cultural landscapes filled with contestation over social power. Puebloan ancestral spirits were keepers of histories on landscapes where power relations were masked, and where new kinds of communities were coalescing. This study demonstrates that the spirits of the dead are important to anthropological understandings of socio-political trajectories. The spirits are at the heart of the ways in which history influences and determines politics. / Dissertation/Thesis / Ph.D. Anthropology 2014

Com o intuito de contribuir para a tipificação da aguardente paulista, 35 analitos foram analisados em 107 amostras coletadas no Estado de São Paulo no momento da sua destilação. Os resultados analíticos foram avaliados utilizando-se análise multivariada (quimiometria). A quimiometria foi utilizada para definir os melhores discriminantes químicos em cada tipo de análise. Na distinção entre a aguardente destilada em alambique e a aguardente destilada em coluna, as análise exploratórias (PCA, HCA e PLS) demonstraram que existe um distinção entre estes dois grupos de bebidas. Os modelos estatísticos criados utilizando-se das análises de LDA e CDA apresentaram uma porcentagem de acerto superior a 95,0% na distinção entre estes dois grupos de bebidas. Quando considerado, na análise exploratória, três grupos de bebidas (alambiques típicos, colunas típicas e alambiques mistos, esta apresentou bons resultados apenas nas análises de PCA e HCA. Não foi criado modelo estatístico considerando três grupos de bebidas. Na última etapa deste trabalho, foi realizada uma análise exploratória (PCA e HCA) nas 107 amostras coletadas no Estado de São Paulo, sem considerar o processo de destilação. Foram encontrados diferentes agrupamentos considerando as características químicas de todas as amostras. No entanto, a correlação definitiva entre estes grupos e as características regionais do Estado de São Paulo não foi observada. / Aiming at achieving typification of the paulista sugar-cane spirits, 35 compounds were analyzed in 107 samples collected in the State of São Paulo at the moment of distillation. The analytical results were obtained through multivariate analysis (chemometric), which was used to determine the best chemical discriminates in each type of the statistical analysis. Exploratory analyses (PCA, HCA and PLS) showed a distinction between the sugar-cane spirits distilled in stills and the ones distilled in continuous columns. After conducting LDA and CDA analyses, the resulting statistical models revealed a significantly high probability (95,0%) to correctly identify the system of distillation used in the process. Exploratory analyses performed in typical stills, typical columns and mixed stills showed good results for PCA and HCA only. No statistical models considering the three groups of drinks were created. The last phase of the present study involved exploratory analyses (PCA and HCA) performed in the 107 samples collected in the State of São Paulo. Considering the chemical characteristics of all samples, different groupings were found. However, a definitive correlation among these groups with the production areas in the State of São Paulo was not observed.

A legislação brasileira estabelece o limite de 150 µg/L para os teores de carbamato de etila (CE ou uretana) em aguardentes. O presente trabalho indica que os teores de carbamato de etila em aguardentes podem ser reduzidos em até 92% do teor original após as aguardentes serem submetidas a uma nova destilação. Para amostras de aguardente recém destiladas (coletadas in loco) foi possível constatar que o CE também se forma após a destilação, e que a formação completa-se após 10 dias. A luz difusa não influenciou, quer na constante de velocidade quer na concentração de CE final. Esta, entretanto demonstrou-se dependente da temperatura. Observou-se que a reação ocorre com kobs de (6,4 ± 0,5) x 10-6 /s, a 25°C e pH 4,5, sendo este valor independente da origem da aguardente e da radiação luminosa. Os parâmetros de ativação para esta reação foram ΔH‡ 34 kcal/mol, ΔS‡ - 69 cal/K e ΔG‡ 54 kcal/mol. Foi possível estimar que o teor de uretana formado no interior do destilador foi inferior a 60% do CE total. Estudos com aguardente nas quais foi adicionado KOCN, indicaram que ocorre a formação de uretana com kobs (8,60 ± 0,4) x 10-5 /s, a 25°C, pH 4,5, com ΔH‡ 20,6 kcal/mol, ΔS‡ - 96,1 cal/K e ΔG‡ 48,7 kcal/mol. Esta reação não foi influenciada pela radiação luminosa (250 a 500 nm), bem como pelo teor alcoólico da aguardente (0,29 a 15,7 mol/L). O rendimento no teor de CE aumentou em função do teor alcoólico do meio, atingindo um valor máximo a 60% v/v. Cálculos quânticos sugeriram que o HNCO é a molécula reativa. Os resultados experimentais colhidos até o momento sugerem a existência de uma reação paralela consumindo parte do HNCO e, portanto limitando kobs e a relação [CE]teórico / [CE]experimental. A adição de NaCN à aguardente também conduz a formação de uretana, mas com constante de velocidade inferior a observada para o KOCN. / Brazilian law establishes the limit of 150 µg/L for ethyl carbamate (EC, urethane) contents in sugar cane spirits. The present work indicates that the levels of ethyl carbamate in spirits may be reduced up to 92% of the original content after undergoing a new distillation. It was observed that EC is also formed after distillation in recent distillated samples collected in loco and that the EC formation is completed after 10 days. The light did not influence either the rate constant or the final EC concentration. However, the rate constant proved to be temperature dependent. It was observed that the reaction occurs with kobs (6.4 ± 0.5) x 10-6 /s at 25°C and pH 4.5, which value is independent of the spirits origin and light radiation. The activation parameters for this reaction were ΔH‡ 34 kcal/mol, ΔS‡ - 69 cal/K and ΔG‡ 54 kcal/mol. It was estimated that the concentration of urethane formed inside the distiller was less than 60% of total EC. Studies adding KOCN in sugar cane spirits indicated that the formation of urethane occurs with kobs (8.60 ± 0.4) x 10-5 /s at 25°C, pH 4.5, with ΔH‡ 20.6 kcal/mol, ΔS‡ - 96.1 cal/K and ΔG‡ 48.7 kcal/mol. This reaction was not influenced by light radiation (250 to 500 nm), as well as the alcohol content of spirits (0.29 to 15.7 mol/L). The yield on EC content increased according to the alcohol content of the medium; reaching a maximum value of 60% v/v. Quantum calculations have suggested that HNCO is the reactive molecule. The experimental results collected so far suggest the existence of a parallel reaction which consumes part of HNCO and therefore limits kobs and the relationship [CE]theorical / [EC]experimental. The addition of NaCN to sugar cane spirits also leads to urethane formation, although with lower rate constant compared to the one observed for KOCN.

The study of pneumatology is important and necessary in theology, and also in the church. What Christians have to know and understand about it must be taught clearly. The nature and work of the Spirit of God should be mastered by every believer in Jesus Christ. In this way, wrong concepts and teachings can be rejected by the Christian way of life, in the church especially in Africa. It is very noticeable that Africans, in their traditional worldview are conscious of the existence of the Supreme Being, spirits, divinities, ancestral spirits and the spiritual world with its diversity. Africans, Christians and non-Christians believe that around them there are invisible spiritual beings and because of this consciousness they are haunted by the wish to discover what is really going on in the invisible world of the spiritual realm. Most Africans consider the existence of the ancestral spirits as a very important matter and they are in daily need to consult them about every event happening among them in their traditional context. In every event they believe there is always somebody, meaning a spirit, behind what is happening. A death or an accident cannot happen without having been caused by a spirit especially an ancestral spirit. The ancestral spirits are thought to be active in the lives of their living descendants on earth. Ancestral spirits are ambivalent in their relation with the living. They can bring good things to their descendants if they are well treated. They harm and molest them when they are angered by their descendants. The fact that Africans have been confronted with the Gospel has had an impact on the lives of Africans. We have to acknowledge that many things in the conduct of African culture have changed or are going to change in the practical lives of Africans. Although the Gospel has had an impact on the people in Africa, it is unfortunately observed that some Africans do not manifest real change. Christian Africans, despite this encounter with the Christian faith, usually revert to traditional practices in case of hardships like accident, incurable diseases and barrenness, for example. The context of religious pluralism which Africans are experiencing, presents an open door to syncretism. Traditional practices are seriously against the biblical teaching and practices. Christians in the church are found (many times) to be involved in these traditional practices where they fear the attacks of their ancestral spirits or the misfortunes by other spirits. The Spirit of God is active in the world and also in Africa. Christians have to rely on God and not on their ancestral spirits for the sustenance and support in different domains of life. The solution to this on-going attitude of Africans to the spirits can only come from the Word of God. It is absolutely important to continue with the proclamation of the Gospel to Africans. This proclamation of the Word of God must be taken seriously by the church and Christians in Africa. It is only the message from the Bible that can free Africans from their belief in the ancestral spiritual world. / PhD (Dogmatics), North-West University, Potchefstroom Campus, 2015

Thesis (MScAgric)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: The WineScan FT120 is widely used in wine laboratories across South Africa. The WineScan FT120 uses Fourier transform infrared (FT-IR) spectroscopy with multivariate data analysis to correlate spectra with chemical compositional data. Ready-to-use, commercially available calibration models for a FT-IR spectroscopy instrument are an advantage for unskilled users and routine analysis. Introducing spirit products to this technology introduced new interferences, which necessitated vastly different calibrations models to compensate for the changes. Accuracy, precision and ruggedness of the reference methods validated during method validation, verified the suitability of the reference methods used to quantify the parameters in question before calibration model building was attempted. Various principal component analysis (PCA) were performed prior to the calibration step with the aim to identify outliers and inspect groupings. PCA models could identify samples with atypical spectra and differentiate between product types. Two tactics regarding data sets for calibration set-up was experimented with, all the products together and calibration models per product. Partial least squares (PLS) regression was used to establish the calibration models for ethanol, density, obscuration and colour. With all the calibration models, the calibration models based on the product specific data sets, achieved better predicting statistics. The best performing ethanol calibration models achieved Residual mean square error of prediction (RMSEP) = 0.038 to 0.106 %v/v and showed significant improvement on previously reported prediction errors by Lachenmeier (2007). The results for the density calibration showed a similar trend, with the product specific calibration models outperforming the calibration model when all samples were included into one calibration model. This study produced novel results for quantification of obscuration (RMSEP = 0.10 and 0.09 in blended brandies and potstill brandies, respectively) and colour (RMSEP < 2.286 gold units) of brandies and whiskies. The correlation coefficients (R²) between true and predicted values, for the four parameters tested, indicated good to excellent precision (0.8 < R² < 1.0). Minimising the variation between the samples of the data set, gave more accurate regression statistics, but this resulted in a lower residual predictive deviation (RPD) value (< 5) that indicated models were not suitable for quantification. Adding more samples per product will add more variability into a data set per product, increase the SD and result in an increase in the RPD. The results pave the way for the development of calibration models for the quantification of other parameters for specific products. Following the groupings of product types, further classifications of brandy brands were investigated. PCA plots showed clear separation between potstill brandies and blended brandies and some degree of clustering between some of the blended brands was observed. Classification of brandies were investigated using the Soft Independent Modeling of Class Analogy (SIMCA) approach resulting in a total correct classification rates between 81.25% and 100% for the various brandy brands. These preliminary results were very promising and highlight the potential of using FT-IR spectroscopy and multivariate classification techniques as a tool for rapid quality control and authentication of brandy brands. Using this work as base for further classification projects, this could be of great benefit to the alcoholic beverage industry of South Africa. Future work will involve the development of a database comprised of more products guaranteed authentic to expand the discriminating options. The results suggest FT-IR spectroscopy could be useful in authentication studies. / AFRIKAANSE OPSOMMING: Die WineScan FT120 is ‘n algemeen gebruikte instrument regoor Suid-Afrika. Die WineScan FT120 gebruik Fourier-transformasie-infrarooi (FT-IR) spektroskopie tesame met multiveranderlike statistiese metodes om spektra te korreleer met chemiese samestellingsdata. Die kommersieël beskikbare kalibrasiemodelle vir die FT-IR spektroskopie-instrument is ‘n voordeel vir onbedrewe gebruikers en roetine ontleding. Blootstelling van spiritusprodukte aan die tegnologie, het nuwe hindernisse bekend gestel en dus is verskillende kalibrasiemodelle genoodsaak om hiervoor te kompenseer. Akkuraatheid, presiesheid en ruheid van die verwysingsmetodes is geëvalueer tydens metodevalidasie. Die verwysingsmetodes is geskik verklaar vir die konstruksie van die kalibrasiemodel met geverifieërde akkurate verwysingsresultate. Verskeie multiveranderlike hoofkomponentanalise (MVK) was uitgevoer voor die kalibrasiestap met die doel om uitskieters te identifiseer en groeperings te inspekteer. MVK modelle kon monsters met atipiese spektra identifiseer en onderskei tussen verskillende produk tipes. Twee taktieke aangaande datastelsamestelling is getoets tydens kalibrasiemodel-opstelling, al die produkte saam en kalibrasiemodelle per produk soos met die MVK aangedui. Parsiële kleinste kwadraat (PKK)- regressie is gebruik vir die opstel van die kalibrasiemodelle vir etanol, digtheid, obskurasie en kleur. Met al die kalibrasiemodelle het die produk spesifieke kalibrasiemodelle beter regressiestatistiek gelewer. Die beste presterende etanol kalibrasiemodelle het ‘n standaardvoorspellingsfout (SVF) = 0.038 tot 0.106 %v/v bereik en het ‘n beduidende verbetering getoon op vorige gerapporteerde studies op spiritusprodukte (Lachenmeier, 2007). Die resultate vir die digtheidskalibrasiemodelle het ‘n eenderse tendens getoon soos die etanol, met die produk spesifieke kalibrasiemodelle wat beter presteer het. Hierdie studie was eerste in sy soort met die kalibrasiemodel vir obskurasie (SVF = 0.10 en 0.09 in gemengde brandewyne en potketel brandewyne, onderskeidelik) en kleur (SVF < 2.286 goud eenhede) van brandewyne en whiskies. Die bepalingskoëffisiënt (R²) vir die vier parameters, dui op goeie tot uitstekende presiesheid (0.8 < R² < 1.0). Vermindering van die variasie tussen die monsters in die datastel, het meer akkurate regressiestatistiek teweeg gebring, maar ‘n laer relatiewe voorspellingsafwyking (RVA) waarde (<5) tot gevolg gehad wat aan dui dat hierdie modelle nie geskik is vir sifting of kwantifisering nie. Die byvoeging van meer monsters per produk sal meer verskeidenheid in die datastel per produk bring, wat dan die standaardafwyking sal laat toeneem en uiteindelik die RVA laat toeneem. Die resultate het die fondasie gelê vir die ontwikkeling van kalibrasiemodelle vir die kwantifisering van ander parameters vir spesifieke produkte. As opvolg tot die groeperings van die produk tipe, waargeneem in die MVK modelle, was klassifikasie van brandewyn handelsmerke ondersoek. MVK modelle het duidelike skeiding gewys tussen potketel en gemengde brandewyne en tot ‘n sekere mate groepering tussen handelsmerke. Klassifikasie van brandewyne was ondersoek met behulp van the Soft Independent Modeling of Class Analogy (SIMCA) met die resultaat van ‘n totale korrekte klassifikasiekoers van tussen 81.25% en 100% vir die verskeie brandewyn handelsmerke. Hierdie voorlopige resultate toon belowend en beklemtoon die potensiaal van FT-IR spektroskopie en chemometrics tegnieke as toerusting vir die vinnige kwaliteitskontrole en egtheid van brandewyn handelsmerke studies. Met hierdie werk as basis vir verdere klassifikasie projekte, kan dit ‘n groot aanwins wees tot die alkoholiese drank industrie van Suid-Afrika. Toekomstige werk sal insluit die ontwikkeling van ‘n databasis saamgestel met meer gewaarborgde egte produkte om die klassifikasie uit te brei.

Esta tese é resultado da pesquisa realizada entre as famílias tupi guarani, que compõem a aldeia Ywy Pyhaú, situada no município de Barão de Antonina, sudoeste do estado de São Paulo. Trata-se de uma etnografia cujo intuito é abordar as múltiplas dimensões do movimento da pessoa, dentre eles os sonhos (xeke rupi...), tema que orientou a pesquisa de doutorado e guiou a escrita desta tese. Além dos sonhos se apresentarem como possibilidades de relações entre os diversos tipos de gente que habitam o cosmos, é através deles que recebem seus mborei (cantos-reza), aconselhamentos e mensagens divinas, bem como, revelações de Nhanderu, que podem tanto interferir no dia-a-dia das pessoas e em suas decisões pessoais quanto servir de impulso a eventos maiores como, por exemplo, as mudanças nos locais onde constituem suas aldeias. Evidenciando assim, que aquilo que experienciam durante o sono, influencia sua vida desperta. No entanto, por se tratar de uma das dimensões do movimento da pessoa, não é possível dissociar os sonhos de outras tantas capacidades e, consequentemente, discutir a seu respeito sem abordar, também, suas práticas de territorialidade, suas formulações acerca de seus corpos-espíritos, assim como a importância que atribuem às relações entre parentes. Em suma, pretende-se demonstrar, articulando temáticas tão variadas, que para as famílias tupi guarani viver junto aos parentes, em uma terra boa, é o que as fortalece, e possibilita que tenham bons sonhos, ocasiões nas quais recebem saberes e poderes das divindades. / This dissertation is the result of research carried out among tupi guarani families, which make up the village Ywy Pyhaú, and live in Barão de Antonina city, southwest of São Paulo state. This is an ethnography that has the intention of approaching the multiple dimensions of the person\'s movement, including dreams (xeke rupi); a theme that guided this doctoral research and the writing of this thesis. In addition to dreams presenting themselves as possibilities of relations among the different types of people who inhabit the various Tupi Guarani worlds, it is through them that people receive their mborei (song-prayer), as well as counseling and divine messages and Nhanderu´s revelations that can both interfere in their daily lives and in their personal decisions, and major events, such as changes in the locations of their villages. This shows that what they experience during sleep, affects their waking life. However, because the dream is one of the dimensions of a person\'s movement there is no way of dissociating them from many other capacities. This, in turn, gives rise to the discussion of the territorial practices of the tupi guarani families, their formulations about the body-spirits and the importance they attach to relations among relatives. In short, by articulating these different themes, this ethnography intends to demonstrate, that living with relatives in a good land, is what strengthens the Tupi Guarani and enables them to have good dreams, those by which they can receive knowledge and power from the divinities.
