Cross, K. C. "Enemy and ancestor : Viking identities and ethnic boundaries in England and Normandy, c.950-c.1015." Thesis, University College London (University of London), 2014. http://discovery.ucl.ac.uk/1417574/.
Full textAbstract:
This thesis is a comparison of ethnicity in Viking Age England and Normandy. It focuses on the period c.950-c.1015, which begins several generations after the initial Scandinavian settlements in both regions. The comparative approach enables an investigation into how and why the two societies’ inhabitants differed in their perceptions of viking heritage and its impact on ethnic relations in this period. Written sources provide the key to these perceptions: genealogies, histories, hagiographies, charters and law codes. The thesis is the first study to juxtapose and compare these sources and aspects of Viking Age England and Normandy. The approach to ethnicity is informed by the social sciences, especially Fredrik Barth’s Ethnic Groups and Boundaries. The emphasis here is on ethnic identity as a social construct and as a product of belief in group membership. In particular, this investigation treats ethnic identity separately from cultural markers such as names, dress, appearance, and art. In doing so, it presents a new perspective in discussions of assimilation after Scandinavian settlement. For the purpose of analysis, ‘ethnicity’ has been divided into three strands: genealogical, historical and geographical identity. Sources from England and Normandy are compared within each of the three strands. The thesis demonstrates the development of a single ‘viking’ group identity in Normandy, which was defined in distinction to the Franks. In England, on the other hand, ‘viking’ and ‘Scandinavian’ identities held various meanings and were deployed in diverse situations. No single group laid exclusive claim to viking heritage, nor completely rejected it. Ultimately, it is argued that viking identity was used as a tool in political and military conflicts. It was not an expression of association with Scandinavian allies, but most often was used as a more local means of distinction within England and Normandy.

Full textAbstract:
Este trabalho apresenta um estudo sobre a obtenção de filmes de TiO2 cristalinos e com propriedades fotoinduzidas, utilizando tecnologias de plasma, sobre substratos de aço carbono AISI 1015. É bem conhecido que a nitretação a plasma contribui para aumentar a adesão de filmes e a resistência à corrosão de substratos metálicos. No entanto, os estudos sobre propriedades fotocatalíticas do TiO2 sobre substratos de aço não investigam o uso de aço carbono nitretado. O principal objetivo deste trabalho é investigar a deposição de filmes de TiO2 fotocatalíticos sobre aço carbono nitretado a plasma, obtido através de um tratamento duplex que envolve a nitretação a plasma e a subsequente deposição por pulverização catódica (sputtering). Para tanto, o processo de pesquisa foi dividido em duas partes: (i) determinação de condições de deposição apropriadas para a obtenção de filmes cristalinos de TiO2 semicondutor, utilizando as técnicas de deposição a plasma conhecidas por magnetron sputtering convencional (MS) e triodo magnetron sputtering (TMS). (ii) Estudo dos processos fotoinduzidos dos filmes cristalinos de TiO2 semicondutor sobre amostras de aço carbono AISI 1015 nitretadas e não nitretadas a plasma. Na primeira etapa os filmes foram depositados em vidro para determinação da composição química por espectrometria de retroespalhamento de Rutherford (RBS) e da energia de band gap ótico (Tauc plot). As amostras foram caracterizadas por difração de Raios X (DRX), perfilometria, microscopia eletrônica de varredura (MEV) e microscopia de força atômica (AFM). A fotoatividade dos filmes foi avaliada através do efeito de hidrofilicidade fotoinduzida por meio do monitoramento da molhabilidade das superfícies e do efeito de fotocatálise heterogênea por meio da degradação do corante azul de metileno (AM). Os filmes de TiO2 cristalinos obtidos sobre vidro foram depositados pelas técnicas de sputtering reativo (MS e TMS) com alvo em modo óxido e apresentaram predominantemente a fase anatase A(101) com energias de band gap em torno de 3,4 eV. Sobre os substratos de aço, foram realizadas deposições por TMS com alvo em modo óxido, pressão de 7,1 mTorr (10,6 sccm O2 / 3,2 sccm Ar), potência de 475 W e temperatura do substrato em 290 C durante 120 minutos. Em substratos de aço não nitretados, somente a fase anatase A(101) é obtida. Os pré-tratamentos de nitretação a plasma (80%N2/20%H2 e 20%N2/80%H2, 2,0 Torr, 5,0 horas, 350 C) aumentam a rugosidade do substrato e exercem um papel importante no crescimento do filme de TiO2, favorecendo o crescimento da fase rutile. A modificação da rugosidade da superfície do substrato pelo pré-tratamento de nitretação a plasma afeta a molhabilidade dos filmes não fotoativados de TiO2. Todos os filmes cristalinos de TiO2 depositados sobre o aço tornam-se superhidrofílicos sob a irradiação ultravioleta e permanecem neste estado por pelo menos 24 horas. O filme de TiO2 depositado sobre o substrato de aço não nitretado apresenta um desempenho fotocatalítico ligeiramente superior aos filmes de TiO2 depositados sobre os substratos de aço pré-nitretados a plasma.

Previous issue date: 2005No Brasil, o aumento no isolamento de microrganismos resistentes aos antimicrobianos e a freqüente incidência de diarréias causadas por linhagens patogênicas de Escherichia coli ocasionam elevados gastos com hospitalização. Estes fatores têm contribuído para que vários pesquisadores busquem formas alternativas no tratamento das doenças infecciosas. Visando um provável uso de Saccharomyces cerevisiae UFPEDA 1015 como probiótico, a capacidade antagonista desta levedura sobre o crescimento das linhagens de E. coli UFPEDA 84, da coleção de cultura do Departamento de Antibióticos, LBFM10, produtora de β- lactamase e uma do sorotipo entero-hemorrágica O157:H7 foi investigada. Os resultados foram comparados aos obtidos para a levedura Saccharomyces boulardii 17, cientificamente reconhecida como probiótica. Nos ensaios para avaliação do antagonismo microbiano, foram utilizadas culturas de E. coli e Saccharomyces, padronizadas em 106 e 107 UFC/mL, respectivamente. A inibição do crescimento da cultura bacteriana foi avaliada através da enumeração das células viáveis durante o período de 24 horas de incubação a 35ºC. Em todos os ensaios foram observadas reduções significativas (p<0,001) das culturas bacterianas. Ao término do experimento foram obtidas reduções superiores a 2,5 log10 UFC/mL, para E. coli UFPEDA 84 e 2,0 Log10 UFC/mL, para o sorotipo entero-hemorrágico O157:H7 e para a linhagem produtora de β-lactamase. O caráter antagonista de S. cerevisiae UFPEDA 1015 sugere seu uso potencial no tratamento de diarréias causadas por E. coli, entretanto estudos adicionais para caracterização definitiva como probiótico são necessários

Ward, Robert Carrington. "Political correspondence relating to Kingston-upon-Hull, 1678-1835." Thesis, University of Leeds, 1989. http://etheses.whiterose.ac.uk/1015/.
Full textAbstract:
This study covers aspects of political life at Kingston-upon-Hull between 1678 and 1835, and is part history and part edition. The historical section is an essay on the character and course of Hull politics between these dates. The edition on which that essay is based, consists of a selection from the surviving correspondence. The resulting picture is fragmentary, but it does contribute to our understanding of Hull at that time. The years 1678 to 1835 were marked by a political stability at Hull established during the first ten years and challenged only during the concluding five. Until the mid 1830's local political power was held by a merchant-maritime oligarchy which in times of need called upon local magnates who served the town as High Stewards. The Crown had some influence at Hull, as it was a garrison town and port; but the town corporation, Trinity House, Dock Company, and a number of wealthy families, some of whom had reached gentry status, held the monopoly of political influence. The freeman electorate was large, and as elections approached, unregistered voters pressed the Bench for their franchise. Some attempt was made by the corporation to restrict this. The paying of polling money was almost inevitable, especially in the later eighteenth century, and wise candidates also contributed to local charities, clubs and racing plates. Members of Parliament kept the town fully informed of national political issues especially up to about 1710. From then until the late 1760's the members seem less assiduous in their correspondence, and also in their performance in the Commons. Between 1766 and 1820 the Rockingham Fitzwilliam interest returned many personal nominees, and the quality of many of the members rose. These Whig magnates did not, however, have a monopoly at Hull. Wilberforce stood as an independent and later several government, or perhaps Tory candidates, were returned. Closely contested and expensive elections were common after 1796. Threats from Jacobites and American privateers, with the possibility of a French invasion, caused local political squabbles, but the French danger may have helped prevent the spread of revolutionary societies and Radicalism was really born in Hull in 1818 with the Political Protestants. However it played some part in turning Hull Whig/Liberal opinion against Liverpool's Tory government. The 1830's, with the campaign for the Reform and Municipal Corporation Acts, led to a crystallisation of local political parties which culminated in the defeat of the Tory corporation in the municipal election of 1835. The activities of the radical Acland added to the political strife, but he overplayed his hand. The stability created by conflict in the 1680's was transformed by conflict in the 1830's. The intervening years thus have some unity.

Full textAbstract:
El càncer de pàncreas és la quarta causa de mortalitat en el món industrialitzat. Per tant cal avançar cap a la recerca de noves aproximacions terapèutiques que ens permetin millorar aquest pronòstic. Actualment la gemcitabina és el fàrmac d'elecció, tot i que els resultats són clarament insuficients. En aquest marc s'ha desenvolupat aquest treball amb l'objectiu de millorar els efectes de la gemcitabina emprant estratègies de teràpia gènica en models in vitro i in vivo de càncer de pàncreas humà.La primera aproximació ha consistit en la reintroducció dels transportadors de nucleòsids hCNT1 i hENT1 mitjançant vectors adenovirals defectius. Els resultats obtinguts ha posat de manifest que la sobrexpressió del transportador de nucleòsids equilibratiu hENT1 mitjançada per adenovirus permet assolir un augment significatiu del transport sensible a NBTI en línies cel·lulars amb un transport basal baix, alhora que indueix un arrest a la fase G2 del cicle cel·lular i redueix l'expressió d'enzims implicats en el metabolisme dels àcids nuclèics. Per altra banda, la combinació terapèutica de la introducció del transportador hENT1 i el fàrmac gemcitabina indueix, sorprenentment, quimioresistència en un model in vitro. Tanmateix, la transferència del transportador in vivo combinada amb el fàrmac afavoreix la inhibició del creixement tumoral. La introducció per infecció adenoviral del transportador hCNT1 provoca un augment del transport sodi-dependent i indueix un arrest a la fase S del cicle cel·lular en cèl·lules tumorals. La sobrexpressió de hCNT1 indueix mort cel·lular per necrosi i inhibeix eficientment el creixement de tumors al teixit subcutani de ratolins atímics. Al mateix temps, la combinació terapèutica amb la gemcitabina provoca una major inhibició del creixement tumoral.
La segona aproximació s'ha basat en la determinació de la implicació de la comunicació intercel·lular en els efectes citotòxics de la gemcitabina. Així com, la modulació d'aquesta citotoxicitat per sobrexpressió de connexina 26 tant in vitro com in vivo. Els resultats obtinguts han mostrat que els nivells de comunicació intercel·lular mitjançats per unions gap determinen l'eficàcia citotòxica de la gemcitabina. Aquesta correlació posa de manifest que la resposta citotòxica a aquest fàrmac pot amplificar-se per efecte adjacent. L'augment de comunicació cel·lular per sobrexpressió de connexina 26 corrobora l'existència d'efecte adjacent in vitro i millora la resposta antitumoral in vivo.
En la tercera aproximació hem unit la teràpia gènica amb p53 amb la replicació viral en el que s'anomena viroteràpia gènica amb la finalitat de potenciar els resultats previs descrits amb aquestes dues estratègies per separat. Per això, s'han generat adenovirus replicatius armats amb el transgèn de p53 i tatp53 sota el control del promotor de fase tardana (MLP) del virus i s'han caracteritzat els seus efectes en models in vitro i in vivo de càncer de pàncreas humà. El conjunt de resultats ha posat de manifest que l'expressió de p53 en la fase tardana de la replicació adenoviral millora l'acció antitumoral de l'adenovirus quan aquest és injectat intratumoralment.
En l'últim bloc s'ha dut a terme l'establiment i estandarització de xenoimplants ortotòpics a partir de tumors subcutanis de cèl·lules tumorals i de nous models ortotòpics procedents directament de fragments quirúrgics d'adenocarcinomes pancreàtics humans amb la finalitat de poder validar diferents combinacions terapèutiques. L'estandarització i caracterització d'aquests models ortotòpics ha evidenciat que les característiques histològiques i genètiques, així com el patró de disseminació metastàtica dels tumors d'origen es mantenen estables al llarg de, com a mínim, 3 generacions.
Pancreatic cancer is the fourth leading cause of mortality in the industrialized world. Therefore, the research of new therapeutic approaches is essential to improve this negative prognosis. Nowadays, gemcitabine is the standard first line treatment drug, even though results are clearly insufficient. In this framework, the aim of this work has been to improve the effects of gemcitabine by means of gene therapy strategies in in vitro and in vivo models of human pancreatic cancer.
The first approach consists of overexpressing nucleoside transporters hCNT1 and hENT1 through defective adenoviral vectors. Overexpression of hENT1 allows a moderate increase on nucleoside transport activity NBTI-sensitive and is associated with cell cycle arrest. Furthermore, therapeutic combination of hENT1 introduction and gemcitabine enhances the inhibition of tumour growth. Introduction of hCNT1 provokes an increase in sodium-dependent transport activity and induces an S-phase cell cycle arrest. hCNT1 overexpression induces necrosis and efficiently inhibit tumour growth. Besides, combination of hCNT1 with gemcitabine enhances the inhibition of tumour growth.
The second approach is based on the analysis of intercellular comunication involvement on gemcitabine cytotoxicity and the modulation by connexin 26 overexpression. Results show that gap junctions determine gemcitabine cytotoxicity. This correlation reveals that cytotoxic response to this drug could be magnified by bystander effect. The increase in cellular comunication by connexin 26 overexpression confirms the existence of bystander effect in vitro and improves antitumoral response in vivo.
In the third approach, p53 gene therapy and viral replication have been joined to perform gene virotherapy. Replicative adenoviruses armed with p53 or tatp53 under the adenoviral major late promoter (MLP) control have been generated. Their effects have been characterized in vitro and in vivo. The results show that later p53 expression in replicative adenovirus improves antitumoral action of adenovirus when is intratumourally injected.
The last point consists of the establishment and characterization of orthotopic xenografts developed from tumour cells and new orthotopic models obtained directly from surgical human pancreatic adenocarcinoma fragments. These orthotopic models retain histologic and genetic characteristics. Dissemination patterns are stable for at least three generations as well.

Full textAbstract:
This thesis investigates extending the dynamically-typed, functional programming language Scheme, with simulated overloading in order to permit the binding of multiple, distributed defnitions to function names. Overloading facilitates the use of an incremental style of programming in which functions can be defined with a base behaviour and then extended with additional behaviour as it becomes necessary to support new data types. A technique is demonstrated that allows existing functions to be extended, without modifcation, therefore improving code reuse. Using the primitives provided by Scheme, it is possible to write functions that perform like the generic routines (functions) of the programming language EL1. These functions use the type of their arguments to determine, at run-time, the computation to perform. It is shown that by gathering the definitions for an overloaded function and building a generic routine, the language appears to provide overloading. A language extension that adds the syntax necessary to instruct the system to gather the distributed set of definitions for an overloaded function and incrementally build an equivalently applicable generic function is described. A simple type inference algorithm, necessary to support the construction of generic functions, is presented and detailed. Type inference is required to determine the domain of an overloaded function in order to generate the code needed to perform run-time overload resolution. Some limitations and possible extensions of the algorithm are discussed.

Full textAbstract:
The original goal of this project was to build a peer e-mentoring program for parents and measure the effect of the program on persistence. In spite of strong mentor participation, two terms of focused recruiting did not attract mentees. This sparked the question of why those who had successfully navigated the higher education system thought a peer e-mentoring program was needed but those in the process did not. A focused ethnography was designed to try to understand why students with children were resistant to peer e-mentoring. Students with children used technology to integrate the various roles of life. They used smart phones to organize, schedule, and research. They used them to schedule rides or childcare for children, communicated with professors and classmates, reviewed course resources, and whatever else they needed to communicate about. They solved problems by taking them one at time and planning for emergencies with contingencies. These students considered planning their best defense against failing to reach to graduation. They realized establishing and keeping communication lines open was critical. The turned most often to family for help but would reach out to professors and even staff if needed. They looked for professors who were known to go above and beyond for their students just in case they needed to reschedule exams or assignments. The overwhelming consensus about participation was that they just can’t see how it is possible make another commitment. Two mentor participants agreed to be interviewed and shared thoughts about privacy concerns but were willing to take the chance to help ease the way for another student parent. The students with children interviewed expressed the need to find solutions to constantly changing requirements but were not comfortable sharing their problems in a one to one mentoring program. Previous studies have suggested that implementing solutions for non-traditional students required a focused needs assessment. Many programs designed to increase retention for non-traditional students have resulted in exactly the results this one originally faced, a lack of participants or low results. Ultimately these students need just in time solutions for a changing myriad of road blocks to graduation.

According to Jensen (2000:215), though we talk of the growing digital divide between rich and poor countries, Africa has shown encouraging signs that it is rapidly adopting the Internet and making innovative use of the technology. Nevertheless, the continent is still well behind other developing regions of the world in taking advantage of the information and communication revolution. The main reasons for this are the limited and expensive telecommunication infrastructure, small markets, and lack of skills and awareness. At the end of 1996, just 11 of Africa’s 54 countries had local Internet access, but by February 2000 all of the continent’s countries had access in the capital cities (Jensen 2000:215). Excluding South Africa, the number of computers permanently connected to the Internet in Africa exceeded 10,000 early in 1999 (Jensen 2000:215). By January 2000, the total had increased to about 25,000, which means Africa, with an estimated population of 780 million people, has about as many Internet-connected computers (hosts) as Latvia, which only has a population of 2.5 million (Jensen 2000:215). Measuring the actual number of Internet users is difficult, but figures for the number of dial-up accounts supplied by Internet service providers (ISPs) show that Africa has more than 500,000 subscribers (Jensen 2000:215). Each computer with an Internet or e-mail connection supports an average of three users, a recent study by the UN Economic Commission for Africa (ECA) has found (Jensen 2000:215). This puts current estimates of the number of African Internet users at somewhere around 1.5 million. Most are in South Africa with approximately 1 million (Jensen 2000:215). Apart from the widespread use of Internet for business and entertainment purposes, social networking sites are becoming widely popular in South Africa. Although there has been little academic research on social networking sites in South Africa, there have been a few articles on websites, newspapers, and magazines that have touched on this phenomenon. Social networking sites, particularly Facebook, have become very popular among the adult internet user population, as both business and private applications. BMW South Africa, for example, has a Facebook page where video posts of recent car models and photos of cars are placed. The Facebook page also has a link to the company’s website (www.bmw.co.za) on the profile which takes a user straight to the commercial website. FM Tech (www.fmtech.co.za) is technology industry news and opinion website edited by Duncan McLeod, associate editor at the Financial Mail, South Africa’s top-selling and best-read weekly business, technology and current affairs magazine. McLeod’s article, What SA Internet users searched for in 2008, revealed that “Facebook”, “Cape Town” and “games” are the terms that South African Internet users searched for most often in 2008. Farber (2008) suggests that this is according to the results of US Web search giant Google’s annual “Zeitgeist” survey of the top searches worldwide. Farber also includes the year’s list of fastest-rising search terms which showed an enormous interest in international social networking sites. 1.2 Articles from popular media The following four popular articles describe the nature of social networking sites and its influence on South African users. Article 1: Cathryn Reece (2007) wrote an article entitled Facebook fever grips SA. “Cape Town - South Africans have embraced the internet social networking revolution, with over 50 000 new users signing on to the local Facebook network. The Facebook "South Africa" network currently has over 87 000 members - up from 35 000 in May. When a user registers on the site, they are given a blank profile page which they can update with their personal information and are encouraged to join a network. Members can then search the site for their friends and link up to each other, re-creating their social circle on the internet.

Full textAbstract:
This study explored the topic of motivation for intermediate students combining both an objective criterion measure (i.e., standardized test scores) and the self-report of students on self-concept and value of reading. The purpose of this study was to examine how third grade reading achievement correlated with the motivation of fourth grade boys and girls, and, in turn, how motivation related to fourth grade reading achievement.
The participants were fourth grade students (n=207) attending two public, elementary schools in Miami-Dade County who were of primarily Hispanic origin or descent. Data were collected using the Reading Survey portion of the Motivation to Read Profile (1996) which measures self-concept and value of reading in order to measure motivation and the Third and Fourth Grade Reading Florida Comprehensive Assessment Tests 2.0 (FCAT 2.0) to assess achievement. First, a one way Analysis of Variance (ANOVA) was conducted to determine whether motivation differed significantly between fourth grade boys and girls. Second, a path analysis was used to determine whether motivation mediated or moderated the association between FCAT 2.0 third and fourth grade scores.
Results of the ANOVA indicated that motivation, as measured by the Motivation to Read Profile did not differ significantly by sex. Results from the path analysis indicated that the model was significant and that third grade FCAT 2.0 scores accounted for a significant amount of the variance in fourth grade FCAT 2.0 scores once motivation was entered. Results of the study demonstrated that motivation partially mediates, but does not moderate the relationship between FCAT 2.0 third and fourth grade scores.
In conclusion, it can be determined that past student achievement for fourth grade students plays a role in current student achievement when motivation is also considered. It is therefore important in order to improve the quality of fourth grade student’s current performance to take into account a student’s motivation and past achievement. An effort must be made to address students’ motivational needs whether through school wide programs or at the classroom level in addition or in conjunction with cognition. Future research on the effect of self-concept in reading achievement is recommended.

Full textAbstract:
The objectives of this research were to develop and evaluate a field method for in situ measurement of soil properties using visible near-infrared reflectance spectroscopy (Vis-NIRS). A probe with an independent light source for acquiring soil reflectance spectra from soil cores was developed around an existing portable field spectrometer (ASD FieldSpecPro, Boulder, CO, USA; 350-2500 nm). Initial experiments tested the ability of the acquired spectra to predict plant root density, an important property in soil carbon dynamics. Reflectance spectra were acquired from soil containing ryegrass roots (Lolium multiflorum) grown in Allophanic and Fluvial Recent soils in a glasshouse pot trial. Differences in root density were created by differential nitrogen and phosphorus fertilization. Partial least squares regression (PLSR) was used to calibrate spectral data (pre-processed by smoothing and transforming spectra to the first derivative) against laboratory-measured root density data (wet-sieve technique). The calibration model successfully predicted root densities (r2 = 0.85, RPD = 2.63, RMSECV = 0.47 mg cm-3) observed in the pots to a moderate level of accuracy. This soil reflectance probe was then tested using a soil coring system to acquire reflectance spectra from two soils under pasture (0-60 mm soil depths) that had contrasting root densities. The PLSR calibration models for predicting root density were more accurate when soil samples from the two soils were separated rather than grouped. A more accurate prediction was found in Allophanic soils (r2 = 0.83, RPD = 2.44, RMSECV = 1.96 mg g-1) than in Fluvial Recent soils (r2 = 0.75, RPD = 1.98, RMSECV = 5.11 mg g-1). The Vis-NIRS technique was then modified slightly to work on a soil corer that could be used to measure root contents from deeper soil profiles (15- 600 mm depth) in arable land (90-day-old maize crop grown in Fluvial Recent soils). PLSR calibration models were constructed to predict the full range of maize root densities (r2 = 0.83, RPD = 2.42, RMSECV = 1.21 mg cm-3) and also soil carbon (C) and nitrogen (N) concentrations that had been determined in the laboratory (LECO FP- 2000 CNS Analyser; Leco Corp., St Joseph, MI, USA). Further studies concentrated on improving the Vis-NIRS technique for prediction of total C and N concentrations in differing soil types within different soil orders in the field. The soil coring method used in the maize studies was evaluated in permanent and recent pastoral soils (Pumice, Allophanic and Tephric Recent in the Taupo-Rotorua Volcanic Zone, North Island) with a wide range of soil organic matter contents resulting from different times (1-5 years) since conversion from forest soils. Without any sample preparation, other than the soil surface left after coring, it was possible to predict soil C and N concentrations with moderate success (C prediction r2 = 0.75, RMSEP = 1.23%, RPD = 1.97; N prediction r2 = 0.80, RMSEP = 0.10%, RPD = 2.15) using a technique of acquiring soil reflectance spectra from the horizontal cross-section of a soil core (H method). The soil probe was then modified to acquire spectra from the curved vertical wall of a soil core (V method), allowing the spectrometer’s field of view to increase to record the reflectance features of the whole soil sample taken for laboratory analysis. Improved predictions of soil C and N concentrations were achieved with the V method of spectral acquisition (C prediction r2 = 0.97, RMSECV = 0.21%, RPD = 5.80; N prediction r2 = 0.96, RMSECV = 0.02%, RPD = 5.17) compared to the H method (C prediction r2 = 0.95, RMSECV = 0.27%, RPD = 4.45; N prediction r2 = 0.94, RMSECV = 0.03%, RPD = 4.25). The V method was tested for temporal robustness by assessing its ability to predict soil C and N concentrations of Fluvial Recent soils under permanent pasture in different seasons. When principal component analysis (PCA) was used to ensure that the spectral dimensions (which were responsive to water content) of the data set used for developing the PLSR calibration model embraced those of the “unknown” soil samples, it was possible to predict soil C and N concentrations in “unknown” samples of widely different water contents (in May and November), with a high level of accuracy (C prediction r2 = 0.97, RMSEP = 0.36%, RPD = 3.43; N prediction r2 = 0.95, RMSEP = 0.03%, RPD = 3.44). This study indicates that Vis-NIRS has considerable potential for rapid in situ assessment of soil C, N and root density. The results demonstrate that field root densities in pastoral and arable soil can be predicted independently from total soil C, which will allow researchers to predict C sequestration from root production. The recommended “V” technique can be used to assess spatial and temporal variability of soil carbon and nitrogen within soil profiles and across the landscape. It can also be used to assess the rate of C sequestration and organic matter synthesis via root density prediction. It reduces the time, labour and cost of conventional soil analysis and root density measurement.

The design, simulation, and measurement of two bulk-driven down-conversion mixers with on-chip
transformer baluns in 0.18 μm CMOS is presented. Applying either the RF signal or the
local oscillator (LO) signal to the bulk connection of the transistors allows the amplification and
switching stages of a conventional mixer to be combined into a single stage, thus improving the
voltage headroom of the mixer. The addition of a transformer balun to the mixers improves the
input impedance match, provides passive voltage gain, and performs single-ended to balanced
conversion. A semi-analytical power-series analysis of the mixers is also presented. The mixer in
which the RF signal is applied to the gates of the mixing transistors achieves a measured input-referred
1-dB compression point (P1dB) of −14 dBm, an input-referred third-order intercept
point (IIP3) of −5.2 dBm, a gain of 13.6 dB, a noise figure (NF) of 26 dB, and an LO-to-RF
isolation of 50 dB. The overall performance of both mixers is found to be comparable with
other CMOS mixers, but with a higher noise figure (which can be mitigated with a high gain
low-noise amplifier (LNA)).

Full textAbstract:
Translation is regarded as a constrained activity (Boase-Beier & Holman, 1999: 7). During the process of translation, there are inevitably factors that influence the translator. However, the factors influencing Taiwanese translators have rarely been investigated in translation studies. This is especially so of the time in the late 1980s when society, culture, and politics were in rapid transition. This study sets out to investigate potentially influential factors operating on Taiwanese translators during the translation process by considering three translations focusing on gender and race issues in the novel The Color Purple. Three versions were translated into Chinese in the same year, 1986. Such a rare occurrence gives us the opportunity to examine how these potentially influential factors, particularly the ones from the wider social context, affected each translation, and to draw wider implications for how translators tackled issues of gender and race in a socially sensitive context. The study adopts and modifies Chesterman's causal model (1992) as the theoretical framework; the study also uses Leuven-Zwart's transeme model (1989) and the concept of critical discourse analysis to investigate semantic shifts and ideological concerns in the gender and race issues in the three Taiwanese versions. Interviews are used to provide additional data. Our findings suggest that each translator, while tackling ideologies of anti-sexism and anti-racism in the original text, was influenced by individual factors, leading to divergent re-presentations. Nonetheless, rather than simply being influenced and conditioned, these variables to some extent empowered the translators to push the boundary of the prevailing attitudes in their translations. The translators' decisions on linguistic items, therefore, became their distinctive, personal responses to the target society, the translation field and the original.

Moretti, Luca. "Putnam's internal realism." Thesis, King's College London (University of London), 2003. http://sas-space.sas.ac.uk/1015/.
Full textAbstract:
This work is intended to ascertain whether Putnam’s internal realism is actually a realist doctrine. Putnam has opposed internal realism, which maintains that truth is an epistemic notion (specifically, idealised rational acceptability), to metaphysical realism, which holds that truth is a non-epistemic notion (in particular, a correspondence relationship between sentences and extra-linguistic facts). Putnam has argued that, even if metaphysical realism is untenable, realism is still defensible, for internal realism is a form of realism. In my work, I leave aside the question of the correctness of Putnam’s arguments against metaphysical realism and I directly focus upon internal realism. I first present this position and I set out its realist characteristics: Putnam’s position can be characterised as one that originated in an attempt to develop Dummett’s anti-realist notion of truth in a realist direction. I show that this effort is in part successful. Next, I raise objections against internal realism and I show that, despite its merits, Putnam’s position is not a form of realism. This is so mainly because internal realism may collapse into relativism, which – I argue – is not realism, and because the internal realist cannot explain how the world, which is causally independent of our minds, makes statements true or false. Since Putnam’s probably constitutes the best possible attempt to produce an epistemic view of truth compatible with realism, I conclude that truth conceived as an epistemic notion is incompatible with realism. I finally suggest that realism can be restored if Putnam’s arguments against metaphysical realism can be shown to be incorrect, so that a non-epistemic notion of truth can be rehabilitated.

Full textAbstract:
From the middle of the seventeenth century until 1853, the Japanese shogunal government virtually isolated Japan from the rest of the world. Only the Chinese and the Dutch were allowed to maintain a trading post in the harbour of Nagasaki. All dealings with the Dutch traders were subject to strict controls, and the interpreters that were trained to liaise with them had to swear a blood oath to secrecy. Nevertheless, information regarding the scientific and technological advances that were made in the West during this period managed to penetrate this barrier, and eventually grew, to some extent with official sanction, into a popular branch of scholarship known as rengeku, literally 'Dutch learning'. Since nearly all of the academic knowledge that reached Japan from the West arrived in written Dutch, the Dutch language became the language of science in Japan during this period, and a necessary subject of study for allrangaku scholars. This thesis is the first study in English that examines the development of the study of the Dutch language in Japan during the period through an analysis of the textbooks and dictionaries that were produced in Japan. The works selected for this study are those considered to be representative of, or significant to, the development of the study of Dutch and attendant increase of awareness of Western linguistic concepts, many of which were imposed, for better or worse, on the Japanese language. Other, less influential documents, are occasionally also discussed, to demonstrate the false trails and misunderstandings that can emerge when a foreign language is presented to students without the benefit of demonstrated current and practical usage. Initially Dutch language study was restricted to the development of skills among the Dutch interpreters in Nagasaki, who compiled word lists for personal use. These lists developed from primitive and limited glossaries into relatively sophisticated Chinesestyle lexicons and finally evolved into the large-scale Haruma dictionaries of the early nineteenth century. Early attempts at understanding the structures of the Dutch language, both by interpreters and academics, failed to provide practical insights. An important i breakthrough was achieved when retired interpreter Shizuki Tadao (1760-1806) began to produce translations of Nederduytsche Spraakkonst('Dutch Grammar') by William Sewel, and applied Western linguistic concepts to the Japanese language. This new understanding gave rise to a consistent structural approach to the study of Dutch, as a result of which language study became more consistent and translations more sophisticated. Although the end of national isolation in the middle of the nineteenth century meant that the study of Dutch was soon abandoned in favour of other European languages, many words in the Japanese language, particularly in relation to science and technology, are of Dutch origin. More importantly, many of the principles and terminology the Japanese use to define the structures of their language stem from the insights into Western linguistics gained during those final decades of the period of national isolation.

Full textAbstract:
Several approaches have been employed for directing the intracellular trafficking
of DNA to the nucleus. Cationic polymers have been used to condense and
deliver DNA and a few specific examples using chitosan as cationic polymer
have been described. The concerted efforts in gene therapy to date have
provided fruitful achievements toward a new era of curing human diseases. A
number of obstacles, however, still must be surmounted for successful clinical
applications.
Therefore, chitosan-plasmid and quaternised chitosan-plasmid complexes
(polyplexes) were investigated for their ability to transfect COS-1 cells and the
results were compared with Transfectam/DNA lipoplexes for transfection
efficiency. All of the chitoplexes utilised in this study proved to transfect COS-1
cells, however to a lesser extent than the Transfectam/DNA lipoplexes, which
served as a positive control. Complexes formed with quaternised trimethyl and
triethyl chitosan oligomers, specifically TMO L and TEO L, proved to be superior
transfecting agents compared to other chitosans. The molecular mass of
chitosan is considered to influence the stability of the chitosan/DNA polyplex, the
efficiency of cell uptake and the dissociation of DNA from the complex after
endocytosis.
In literature it was shown that the toxicity of the chitosan1DNA polyplexes is
relatively low compared to viral gene and lipid non-viral delivery vectors. This
study showed that the percentage viable COS-1 cells when transfected with the
chitosan polymers, oligomers, quaternised chitosan polymers and quaternised
chitosan oligomers (chitoplexes) was higher than the percentage viable cells
when transfected with lipoplexes prepared with Transfectam with the MTT
assay. The Transfectam/DNA lipoplexes induced cell damage and a decreased
viability of COS-1 cells were found. Chitosan/DNA and quaternised
chitosan/DNA complexes did not affect the viability of the cell line. The degree of
quaternisation of the polymers and oligomers and molecular size proved to be
two important factors when considering effective non-viral gene delivery.
It can be concluded that chitosan, especially quaternised oligomeric derivatives
are polysaccharides that demonstrate much potential as a gene delivery system.
The high solubility and low toxicity of chitosan allow its use in a wide variety of
applications in the pharmaceutical industry and, as shown in this study, in gene
delivery.Thesis (Ph.D. (Pharmaceutics))--North-West University, Potchefstroom Campus, 2006.

Full textAbstract:
Female labor force participation varies widely across regions and cultures, typically with more working women in developed than developing countries. Because there are significant differences between developed and developing countries that go beyond GDP, this paper examines the effects of certain development indicators on female workforce participation across these countries. Using models from past literature, I include indicators that cover personal and labor market characteristics. In this analysis, I find that education and unemployment rates continue to be significant determinants of female labor force participation in both developed and developing countries, with several key differences in the effect of various types of unemployment. Furthermore, my study supports the existence of an initial tradeoff between female labor force participation and development as the economic sectors within a country shift. These results provide valuable insights on these general trends across national borders and therefore are important for policy makers.

Full textAbstract:
Vitiligo is an autoimmune disease of the skin characterized by epidermal depigmentation that results from CD8+ T cell-mediated destruction of pigment producing melanocytes. Vitiligo affects up to 1% of the population and current treatments are moderately effective at facilitating repigmentation by suppressing cutaneous autoimmune inflammation to promote melanocyte regeneration. In order to cause disease, CD8+ T cells must overwhelm the mechanisms of peripheral tolerance in the skin and if we understand the suppressive mechanisms that are compromised during vitiligo, we can potentially use this information to improve existing treatments or engineer novel interventions. Therefore, my goal is to characterize the regulatory factors in the skin that suppress depigmentation during vitiligo. Our lab has developed a mouse model of vitiligo that accurately reflects human disease and I used this model to demonstrate that regulatory T cells suppress CD8+ T cell-mediated depigmentation and interact with CD8+ T cells in the skin during vitiligo. In this model of disease, I investigated the molecules involved in regulatory T cell function and observed that the chemokine receptors CCR5 and CCR6 play different roles in regulatory T cell suppression. While CCR6 facilitates regulatory T cell migration to the skin, CCR5 is dispensable for migration but required for optimal regulatory T cell function. Additionally, I used our mouse model to demonstrate that Langerhans cells suppress the incidence of disease during vitiligo. Taken together the results from these studies provide novel insights into the mechanisms of suppression during vitiligo.

Numerous structural end connections are utilized everyday in the marine industry for ship design and/or maintenance. End connection design has been developed in earlier vessel designs and adapted as a general standard for all vessels being designed / built at a facility. Usually the supporting calculations developed to analyze the structural end connection are not available for engineers to re-examine. Furthermore, young engineers employ un-proven end connections in their designs, using the justification “It has been done like this in the past, it should work.†In this thesis, the author concentrates on finite element analysis for thirteen typical end connections used in the marine industry and correlated the shear and moment transfer to an AISC developed empirical beam equation for comparison. The author will rely on first principle equations and finite element analysis to prove the efficiency of various end connections, and draw comparative conclusions per each end connection analyzed.

Microrganismos formam associações com a maioria das espécies animais e um
exemplo fascinante são as múltiplas interações nas colônias de formigas-cortadeiras.
Os efeitos dessas interações (positivos e negativos) se manifestam na sanidade e
desenvolvimento das colônias. Sendo assim, a compreensão das interações que
ocorrem entre os microrganismos das colônias de formigas-cortadeiras A. sexdens é
importante para fundamentar o controle biológico desta praga. Esse presente trabalho
foi dividido em três capítulos. O primeiro capítulo objetivou comparar o
desenvolvimento de colônias de Atta sexdens (Linnaeus) em contato com dois solos:
(i) de área com ninhos e (ii) de área sem ninhos de formigas-cortadeiras. Foram
conduzidos dois experimentos em laboratório. No experimento I, fêmeas recémfecundadas
fundaram a colônia em pote com gesso e, após 106 dias, entraram em
contato com solo. No experimento II, as fêmeas recém-fecundadas fundaram suas
colônias diretamente no solo. A taxa de mortalidade de colônias, após 106 dias da
revoada e se desenvolvendo em pote com gesso, foi de 28,6%. Quando se
desenvolveram desde o início em contato com o solo, a taxa de mortalidade elevouse
a 67,2 %. Os resultados confirmam que as colônias incipientes de A. sexdens
sofrem forte pressão seletiva de microrganismos do solo no momento da fundação.
No entanto, após o surgimento da força operária, mecanismos de defesa imune social,
provavelmente, garantem o desenvolvimento da colônia a despeito da presença de
microrganismos patogênicos no solo dos ninhos. O segundo capítulo objetivou isolar
e identificar actinobactérias de solos de câmaras de jardim de fungos de A. sexdens
e avaliar o efeito inibitório desses isolados sobre fungos associados às colônias de
formigas-cortadeiras. Foram sequenciados o gene 16S rRNA de nove actinobactérias,
sendo seis do gênero Streptomyces, duas do gênero Nocardia e uma do gênero
Kitasatospora. Foi verificado que dois isolados de Streptomyces e um de
Kitasatospora inibiram não só o fungo Escovopsis sp., como também o fungo
entomopatogênico Metarhizium anisopliae e o fungo antagonista do cultivar simbionte
de cortadeiras Trichoderma aff. strigosellum. Uma vez que não existem evidências de
cultivo de actinobactérias na cutícula de operárias do gênero Atta, é possível
hipotetizar que essas operárias estabeleçam simbiose temporária adaptativa com
microrganismos do solo produtores de substâncias antifúngicas e antibióticas e que
vivem em alguma parte de seu ninho ou mesmo no interior do seu corpo. Além disso,
10
os fungos patogênicos para colônias de formigas-cortadeiras presentes no solo
adjacente ao ninho, apesar de constituírem um risco, podem ser controlados pelas
secreções produzidas pelas operárias, bem como pelos metabólitos de algumas
actinobactérias. O terceiro capítulo teve como objetivo verificar a aceitação e
incorporação de iscas contendo micélio de Escovopsis sp. em colônias jovens de Atta
sexdens. Verificou-se o transporte de iscas em todas as colônias do teste. Houve
redução no peso do jardim de fungos das colônias que receberam iscas com
Escovopsis sp., e aumento no peso do jardim de fungos de colônias que receberam
tratamento controle. Conclui-se que a utilização de iscas com micélio de Escovopsis
sp. foi satisfatória para introduzir o fungo parasita no jardim de fungos de colônias de
Atta sexdens.Microorganisms form associations with most animal species, and a fascinating example is the multiple interactions in the colonies of leaf-cutting ants. The effects of these interactions (positive and negative) are exhibited in the health and development of the colonies. Therefore, the understanding of the interactions that occur among the microorganisms into leaf-cutting ants colonies is important to support of biological control of this pest. This work was divided into three chapters. The first chapter aimed to compare the development of colonies of Atta sexdens (Linnaeus) in contact with two types of soil: (i) from an area used for nesting and (ii) from an area not used for nesting of leaf-cutting ants. Two experiments were conducted in the laboratory. In experiment I, newly fertilized females founded the colony in a plastic pot with gypsum and, after 106 days were transferred to a plastic pot with soil. In experiment II, newly fertilized females founded their colonies directly on the soil. Colony mortality rate 106 days after nuptial flight and founding in a plastic pot with gypsum was 28.6%. When they developed directly in contact with the soil, mortality rate increased to 67.2%. The results support that incipient colonies of A. sexdens undergo strong selective pressure from soil microorganisms at the time of foundation. However, after the emergence of the worker force, social immune defense mechanisms likely guarantee the development of the colony, despite the presence of pathogenic microorganisms in the soil of the nests. The second chapter aimed to isolate and identify actinobacteria from soils of fungi garden chambers of A. sexdens and to evaluate the inhibitory effect of these isolates on fungi associated with leaf-cutting colonies. To identify the isolates, the 16S rRNA gene was sequenced from nine actinobacteria: six of Streptomyces genus, two of Nocardia genus and one of Kitasatospora genus. Two Streptomyces and one Kitasatospora isolates inhibited not only the fungus Escovopsis sp., but also the entomopathogenic fungus Metarhizium anisopliae and the antagonistic fungus of the cultivar symbiont of leaf-cutting ant Trichoderma aff. strigosellum. Since there is no evidence of cultivation of actinobacteria on the Atta worker cuticle, it is possible that these workers establish temporary adaptive symbiosis with soil microorganisms producing antifungal and antibiotic substances and living in some part of their nest or even in the interior of their body. It can be hypothesized that pathogenic fungi present in the soil adjacent to the leaf-cutting ant nest, despite the risk they represent, are controlled by the secretions produced by the workers, as well as by the metabolites of some actinobacteria. The third chapter had the objective of verifying the acceptance and incorporation of baits containing mycelium of Escovopsis sp. by young colonies of A. sexdens. We verified the transport of baits in all tested colonies. There was a reduction in the weight of the fungus garden of the colonies that received baits with Escovopsis sp., and an increase in the weight of the fungus garden of colonies that received control treatment. It is concluded that the use of baits with mycelium of Escovopsis sp. was satisfactory to introduce the fungus parasite in the fungus garden of A. sexdens colonies.

Dissertação de Mestrado em Psicologia EducacionalTendo por base investigações recentes, no âmbito do quadro teórico de K. Nelson sobre a representação geral de acontecimentos e desenvolvimento cognitivo e linguístico, assim como investigações acerca da evolução da actividade gráfica infantil e sobre a função da linguagem na actividade, o presente estudo, pretende verificar de que forma a idade e a familiaridade e estruturação temporal de acontecimentos rotineiros, poderão influenciar a complexidade de produções gráficas e de relatos do ponto de vista linguístico. De forma a que este objectivo fosse alcançado, tomou-se por base o paradigma da produção de scripts, no intuito de se poder comparar a performance de crianças de 4 e 5 anos numa tarefa de produção de desenhos e relatos do conteúdo dos mesmos, para dois tipos de acontecimentos previamente seleccionados: "Um dia de Escola" e "Uma festa de Aniversário". A amostra constituída por 64 crianças com idades entre os 4 e os 6 anos, distribui-se por dois grupos: 4 anos e 5 anos. Esperava-se então que, as crianças mais novas produzissem desenhos menos complexos e evoluídos graficamente do que as crianças mais velhas, e que este efeito fosse sobretudo visível no acontecimento "Festa de Anos" por se tratar de um acontecimento menos familiar e estruturado temporalmente. Aguardava-se também, que as crianças mais novas verbalizassem mais durante a execução dos desenhos, sobretudo enunciados reguladores da acção, principalmente no acontecimento "Festa de Anos" por se tratar de um acontecimento menos familiar e estruturado temporalmente, enquanto que as crianças mais velhas verbalizassem mais enunciados antes (planificação) e depois (avaliação) do desenho, principalmente no acontecimento "Dia de Escola", por se tratar de um acontecimento mais familiar e estruturado temporalmente. Esperava-se ainda, que as crianças mais novas emitissem mais enunciados de descrição/etiquetagem para explicarem os seus desenhos, principalmente na explicação dos desenhos sobre a "Festa de Anos" por se tratar de um acontecimento menos familiar e estruturado temporalmente, enquanto que as crianças mais velhas emitissem mais enunciados de acção/acontecimento, principalmente na explicação dos desenhos relativos ao "Dia de Escola", por se tratar de um acontecimento mais familiar e estruturado temporalmente. Por último, previa-se que os relatos para explicar os desenhos se manifestassem menos complexos do ponto de vista linguístico nas crianças mais novas do que nas crianças mais velhas, principalmente no acontecimento "Festa de Anos", por se tratar de um acontecimento menos familiar e estruturado temporalmente; Os dados analisados segundo as grelhas construídas foram sujeitos a um tratamento estatístico. Ao comparar as categorias, quer para cada tipo de acontecimento, quer para comparar pares de categorias entre os dois acontecimentos para um grupo de idade, foi utilizado o teste Wilcoxon. Para realizar uma comparação entre os dois grupos de idade, foi utilizado o teste Mann-Whitney. Os resultados obtidos demonstraram que a idade das crianças e a familiaridade e estrutura dos acontecimentos influenciaram a complexidade das produções gráficas. Constatou-se que as crianças de ambos os grupos verbalizaram mais enunciados durante a execução dos desenhos e de regulação da acção em ambos os acontecimentos. No entanto, no grupo de crianças mais velhas verificaram-se mais enunciados de antecipação durante a execução do desenho e enunciados dirigidos ao experimentador no acontecimento "Dia de Escola", comparativamente ao acontecimento "Festa de Anos". Relativamente ao tipo de enunciados emitidos para explicar os desenhos, verificou-se que as crianças mais novas verbalizaram mais enunciados do tipo descrição/etiquetagem enquanto que as crianças mais velhas verbalizam mais enunciados de tipo acção/acontecimento, sendo este último, sobretudo visível no que diz respeito ao acontecimento "Dia de Escola". A complexidade do discurso linguístico, é influenciado pela idade, embora não se tenham encontrado diferenças entre os dois tipos de acontecimento.

Objectivos: Estimar a idade média da menopausa e identificar a frequência e gravidade dos sintomas climatéricos.
Material e Métodos: Estudo observacional descritivo transversal de 69 mulheres climatéricas, com idades entre 40 e 88 anos, utentes da USF “A Ribeirinha”, entre Outubro de 2010 e Fevereiro de 2011. Para facilitar a recolha dos dados, construiu-se uma aplicação informática intitulada “Menopause Aid”, estruturada em 6 partes: dados sociodemográficos; antecedentes ginecológicos, obstétricos e menopáusicos; Score de Risco de Framingham; Menopause Rating Scale; Factores de Risco para OP; e utilização de THS. A amostra (n=69) foi subdividida em 3 classes: Pré-Menopausa (n=7), Peri-Menopausa (n=25) e Pós-Menopausa (n=28).
Resultados: A idade média da menopausa foi de 50.12 ± 3.871. De um modo geral, os sintomas mais frequentes foram os problemas musculares e das articulações (88.0%), irritabilidade (73.3%) e esgotamento físico e mental (71.7%). Falta de ar, suores e calores foram referidos por 50% das entrevistadas. Relativamente à gravidade dos sintomas, estes foram mais severos no grupo da pós-menopausa (39.3%). Neste estudo encontrou-se uma correlação estatisticamente significativa entre a idade das mulheres e um dos seguintes: sintomas totais da escala MRS (=0.289); sintomas somáticos (=0.258); sintomas urogenitais (=0.388).
Conclusão: O aumento da idade das mulheres traduz-se num aumento da frequência e gravidade dos sintomas climatéricos. Menopause Aid é um programa inovador que engloba os principais parâmetros de avaliação da saúde da mulher e permite uma recolha fácil e sistemática dos dados.Purpose: To estimate the average age of menopause and to identify frequency and severity of climacteric symptoms. Material and Methods: A cross-sectional study of 69 menopausal women, aged between 40 and 88 years was carried out at the USF "A Ribeirinha", between October 2010 and February 2011. To simplify data´s collection, it was created a computer application named "Menopause Aid”, structured in 6 parts: demographic data; gynecological, obstetric and menopausal antecedents; Framingham Risk Score; Menopause Rating Scale; Risk Factors for Osteoporosis; and use of HRT. The sample (n = 69) was subdivided into three classes: Pre-Menopause (n=7), Peri-menopause (n=25) and postmenopause (n=28). Results: The average age of menopause was 50.12 ± 3871. The most frequent symptoms were muscle and joint problems (88.0%), irritability (73.3%) and physical and mental exhaustion (71.7%). Hot flashes were reported by 50% of the women. Climacteric symptoms were more severe in the postmenopausal group (39.3%). In this study, we found a statistically significant correlation between age of women and one of the following: total score of MRS scale ( = 0289), somatic symptoms ( = 0258), and urogenital symptoms ( = 0388). Conclusion: The increasing age of women is reflected in increased frequency and severity of symptoms. Menopause Aid is an original program that comprises the key parameters to assess the health of women, and provides an easy and systematic data´s collection.

Thesis (MTech (Business Administration))--Cape Technikon, Cape Town, 2000The current rationalisation of health care in the Western Cape may result in a decrease in the number of patients attending the Trauma Unit at Groote Schuur Hospital (GSH), one of the two large tertiary care hospitals in the Western Cape. This in turn may result in cuts in staff allocations to this unit. The nursing staff need to be proactive in preventing potential cuts which may compromise the services that they offer. Current statistics collected by nursing managers in the trauma unit at GSH provide an indication of the volume of work handled, but do not necessarily capture the intensity of that work. The purpose of this research project will determine the extent to which nursing care required by patients attending the trauma unit at GSH has increased and to establish appropriate staff workload scheduling. The existing classification systems available for assessing patient acuity levels are no longer suitable as they use patient numbers to describe workload. By using a classification system specifically developed for the use by nurse managers in high care units (trauma units), the appropriate staffing norms based on the acuity level of patients can be determined. Finally, this research project will determine a suitable model for measuring the intensity of workload specific to a trauma unit environment for the effective and efficient allocation of staff.

Full textAbstract:
Les assemblages stratifiés par procédé de brasage sont de plus en plus utilisés dans le secteur de l'outillage rapide appliqué à la fonderie, la plasturgie. . . Cette méthode d'assemblage permet par exemple des géométries originales et le placement de canaux de refroidissement à des positions optimales qu'il est impossible d'atteindre par perçage. Dans la plupart des cas d'application, les assemblages brasés doivent résister aux sollicitations mécanique et thermique en service. Cette recherche est une contribution à la modélisation et à la caractérisation du comportement des assemblages brasés aussi bien du point de vue mécanique que thermique. Les inconvénients des méthodes classiques de modélisation pour traiter des géométries complexes avec des zones raffinées très localisées (affinement extrême du maillage, temps de calcul excessif) nous ont poussés à rechercher une nouvelle méthode pour traiter les problèmes des assemblages brasés. En gérant la présence du joint dans l'assemblage sous forme d'une perturbation, nous avons proposé le couplage de deux méthodes: la méthode des développements asymptotiques raccordés (DAR) et la méthode des éléments finis étendus (X-FEM). La construction de la partie enrichie de la X-FEM est basée sur les solutions proposées par la méthode des DAR suivant cinq variantes d'enrichissement. Les principes fondamentaux ainsi que les méthodes de mise en œuvre du couplage DAR-X-FEM sont présentés à travers le cas unidimensionnel des assemblages brasés. En appliquant la variante d'enrichissement la plus appropriée, le couplage DAR-X-FEM a été étendu par la suite pour modéliser le cas bidimensionnel des assemblages brasés. L'illustration du couplage DAR-X-FEM 2D a été effectuée pour les deux applications: transferts thermiques et chargement mécanique. Afin de mieux comprendre le comportement des assemblages brasés et de valider les résultats obtenus par le couplage DAR-X-FEM, une étude expérimentale a été présentée. Dans un premier lieu, les essais de brasage à haute température ont été effectués. En deuxième lieu, les éprouvettes d'assemblages brasés obtenues par brasage ont fait l'objet d'essais de caractérisation des propriétés mécaniques et thermiques. Enfin, la comparaison entre les résultats expérimentaux et de la modélisation a permis de vérifier la pertinence du couplage DAR-X-FEM proposéLaminar assembly by the means of the brazing process is becoming widely used in the field of rapid tooling used for die casting, plastic injection moulding. . . In most applications, the brazed assembly must withstand the in-service mechanical and thermal solicitations. This research is a contribution to the modelling and the characterisation of the behaviour of brazed assembly in both mechanical and thermal aspects. The deficiencies of the classical modelling methods when modelling of a complex structure with localised variations is concerned led us to search for a new method to treat the problems of brazed assemblies. Considering the presence of the joint in the assembly as a perturbation in a broad structure, we have proposed the coupling of two methods: the matched asymptotic expansions method (DAR) and the extended finite element method (X-FEM). The construction of the enriched part of the X-FEM is derived into five variants of enrichment using the perturbation solutions obtained by the DAR method. The basic principles and methods of implementation of the DAR-X-FEM coupling have been presented through the one-dimensional example of brazed assembly. Applying the most appropriate variant of enrichment, the DAR-X-FEM coupling was subsequently extended to the two-dimensional case of brazed assemblies. The illustration of coupling DAR-X-FEM 2D was performed for two problems: heat transfer and mechanical loading. To better understand the behaviour of brazed assembly and to validate the results obtained by the coupling DAR-X-FEM, an experimental study has been presented. Firstly, high temperature brazing tests have been carried out. Secondly, the brazed specimens were tested to characterize both mechanical and thermal properties. Lastly, the comparison between the experimental and the simulation results confirmed all the interest of the proposed coupling DAR-X-FEM

Por otra parte, la ventaja de usar una metodología que capture las fuentes de volatilidad y las presente de una forma transparente salta a la vista, pues no se requiere la calibración específica de un modelo ni la interpretación de una probabilidad como alta o baja, sino simplemente proveer de la data necesaria para obtener una lectura en múltiples planos de la situación del sistema financiero.
De esta manera, la metodología presentada en este trabajo permite capturar no solo las fuentes internas más comunes, sino las exposiciones que pueden ser posible fuente de contagio para los sistemas financieros de los países latinoamericanos y presentarlas como probabilidades de ocurrencia o de una forma mucho más transparente e intuitiva. El trabajo propone y desarrolla un sistema de alerta temprana, con dos metodologías complementarias que pueden ser aplicadas en la región, para luego mostrar su aplicación específica al caso peruano.

ABSTRACT: This research is to identify the existence or not of excessive consumption of alcoholic drinks by young adults in Higher Education. Simultaneously seeks to assess the behavior of risk that stems from the excessive consumption of alcohol. There was a search quantitative cross and correlational on a sample of 354 students from various institutions of Higher education, Female and male, aged between 18 and 40 years, from the areas of Health, Social Sciences and Humanities and Engineering who responded to a memorandum of questionnaires (Characterization of Participation and Consumption of Alcohol in Academic Holidays; Scale of Consumption of Alcohol in Academic Holidays (ECAFA); AUDIT and Characterization circumstantial) in which measured the consumption of alcohol and risk behavior. The results indicate that there is a moderate consumption of alcohol in young respondents, and few of risk behaviors associated with the consumption. Noted that there is greater consumption of alcohol by male students than female. However it is still possible to see that there is a statistically significant positive correlation between the consumption of alcohol, parties academic and displaced students. Moreover, in descending order, Engineering students present results of consumption of alcoholic beverages significantly higher in relation to students of Humanities and social Sciences and Health students. Some implications of this research are to identify and modify risk behaviors related to alcohol consumption in higher education.

Full textAbstract:
The following thesis will merge the field of legal studies with the field
of Science, Technology, and Society, and will focus on issues surrounding the
gun control debate. The goal is to ultimately bring new light to this hot-
button legal topic through the use of STS scholarship. STS tools and theories,
which have previously been absent from most gun control discussions, have
much to contribute to the discourse in terms of motivating the need for gun
control, fully understanding the user-gun relationship, breaking down
misconceptions about the technology and its role in society, and further
understanding the complex societal network within which guns exist in
America. This will begin first with a discussion of the legal history and
background of firearms in the United States, and will be followed by an STS
analysis of technological agency and somnambulism as they can be applied to
guns. Following this, the Actor Network in which firearms in America are
imbedded will be explored, in order to better understand why they have
been so difficult to regulate. Although this thesis will be heavily policy and
law-focused, the aim is not to propose any specific new policy, but instead to
use STS to conceptualize gun issues from a new perspective that will allow
misconceptions and blockades to be confronted head-on.

Full textAbstract:
Recently-developed technologies for monitoring activity in populations of neurons make it possible for the first time, in principle, to ask many basic questions in neuroscience. However, computational tools for analyzing newly available data need to be developed. The goal of this thesis is to contribute to this effort by focusing on two specific problems. First, we used a point-process regression framework to provide a methodology for statistical assessment of the link between neural spike synchrony and network-wide oscillations. In simulations, we showed that our method can recover ground-truth relationships, and in two types of spike train data we illustrated the kinds of results the method can produce. The approach improves on methods in the literature and may be adapted to many different experimental settings. Second, we considered the problem of source extraction in calcium imaging data, i.e., the detection of neurons within a field of view and the extraction of each neuron’s activity. The data we mainly focus on are recorded with a microendoscope, which has the unique advantage of imaging deep brain regions in freely behaving animals. These data suffer from high levels of background fluorescence, as well as the potential for overlapping neuronal signals. Based on the existing constrained nonnegative matrix factorization (CNMF) framework, we developed an efficient method to process microendoscopic data. Our method utilizes a novel algorithm to initialize the spatial shapes and temporal activity of the neurons from the raw video data independently from the strong fluctuating background. This step ensures the efficiency and accuracy of solving a nonconvex CNMF problem. Our method also models the complicated background by including its low-spatial frequency structure and the locally-low-rank feature to avoid absorbing cellular signals into the background term. We developed a tractable solution to estimate the background activity using this new model. After subtracting the approximated background, we followed the CNMF framework to demix neural signals and recover denoised and deconvolved temporal activity. We optimized several algorithms in solving the CNMF problems to get accurate results. In practice, our method outperforms all existing methods and has been adopted by many experimental labs.

AN ABSTRACT OF THE DISSERTATION OF DIANE M. LAND, for the Doctor of Philosophy degree in Health Education, presented on December 3, 2014, at Southern Illinois University Carbondale. TITLE: PSYCHOSOCIAL PREDICTORS OF HIGH SCHOOL ADOLESCENTS' SUN-TANNING AND SUN-PROTECTIVE BEHAVIORS MAJOR PROFESSOR: Dr. Roberta Ogletree Background: The incidence of skin cancer among adolescents and young adults is increasing in the United States (American Cancer Society, 2014). Ultraviolet radiation (UVR) exposure via sun-tanning is considered an important risk factor for development of melanoma. Sun-induced skin damage and sun-tanning habits are initiated in early life and promoted through later sun exposure patterns. Social norms, appearance attitudes, and perceptions of fitness and health attributed to sun-tanned skin and tanning bed usage have been established. The primary aim of this study was to investigate high school adolescents' sun-related attitudes and behaviors through a theoretical framework of psychosocial constructs grounded primarily in Bandura's (1986) Social Cognitive Theory. Assessing the differences in predictors of adolescents' UVR sun-tanning and sun-protective behaviors (including sunless tanning) has the potential to aid in developing age-appropriate strategies to prevent the adoption of sun-tanning habits and reinforce more health enhancing behaviors. Methods: This research study utilized a quantitative, cross-sectional, descriptive research design to assess the attitudes, motivations, and behaviors regarding sun-tanning and sun-protective practices of high school adolescents in rural Southern Illinois. A purposeful sample of 9 - 12th grade students (n = 900) enrolled in physical education class during the fall 2014 semester were invited to complete a self-report paper and pencil survey consisting of 56 Likert-type items and five demographic variables. Results: A total of 156 adolescents received parental permission and completed the survey, providing a 17.3% response rate. Intentional sun-tanning (UVR exposure) continues to be prevalent. Study participants reported sun-tanning more often and had a higher number of sunburns within the past twelve months that in previous national studies. Participants from low socio-economic status (SES) were more likely to outdoor suntan and use sunless tanning lotions, gels or creams than their not low SES counterparts. For sun-tanning behaviors, a significant amount of the variance in mean sun-risk behavior score was explained by the constructs situation, outcome expectations, and value expectancies. Situation, outcome expectations, value expectancies, and self-efficacy were all predictive of outdoor sun-tanning; whereas only outcome expectations were predictive of indoor sun-tanning. Self-efficacy explained a significant proportion of variance in sun-protective behavior mean score. Outcome expectations were predictive of both sunless tanning with lotions, creams or gels and spray tanning product use. Sunless tanning appears to be used as both an additive behavior for those reporting the highest frequency of indoor tanning and a substitution behavior for adolescents who reported never indoor tanning.

Full textAbstract:
Carpal tunnel syndrome is a frequently encountered chronic peripheral nerve entrapment disorder caused by mechanical insult to the median nerve, which may occur from impingement by the surrounding digital flexor tendons and the tunnel boundaries. Anatomic finite element models of the carpal tunnel provide a method to evaluate the potential contact stresses that may develop on the median nerve between the digital flexor tendons and tunnel boundaries. Realistic finite element simulations are dependent upon the use of physiologically accurate material properties. The purpose of this work was to ascertain material properties for the digital flexor tendons, median nerve and transverse carpal ligament to inform finite element simulations. The compressive mechanical behavior of the digital flexor tendons, median nerve and transverse carpal ligament was characterized under functionally relevant axial tensile loads. These properties can now be implemented into full scale finite element models of the carpal tunnel to evaluate the mechanism of insult to the median nerve leading to the development of carpal tunnel syndrome.

Several reports of North American bumble bee (Bombus Latreille) decline have been documented across the continent, but no study has fully assessed the geographic scope of decline. In this study I discuss the importance of Natural History Collections (NHC) in estimating historic bumble bee distributions and abundances, as well as in informing current surveys. To estimate changes in distribution and relative abundance I compare historic data assembled from a >73,000 specimen database with a contemporary 3-year survey of North American bumble bees across 382 locations in the contiguous U.S.A. Based on my results, four historically abundant bumble bees, B. affinis, B. occidentalis, B. pensylvanicus and B. terricola, have declined by 72 - 96% relative abundance across their native distribution, while B. bifarius, B. bimaculatus, B. impatiens, and B. vosnesenskii appear to be relatively stable. Finally, I provide some notes on the distribution, abundance, and frequency of Nosema bombi infections in Alaskan B. occidentalis.

Full textAbstract:
Oregon voters legalized physician-assisted death in 1997 by passing the Oregon Death with Dignity Act. This law allowed terminally ill, mentally competent adult residents of the state to legally obtain a physician's prescription to hasten death under narrow sets of circumstances. The purpose of this study was twofold: to examine contemporary patterns of support for the law in Oregon and to explore how opinions have changed over time on the issue. This study examined patterns of public support among a random sample of registered Oregon voters for the state's death with dignity law, using a mixed mode (mail, online, and phone) cross-sectional survey (n = 442). The findings indicate a pattern of growing support with potential Oregon voters split 80%-20% on the issue, a substantial increase from the 60%-40% approval margin at the ballot box in 1997. Various demographic variables, as well as attitudinal factors, were explored in building a binary logistic regression model predicting probability of support. Frequency of church attendance, views about physician participation in the process, and opinions about Death with Dignity as an individual right were significant predictors of support. Frequent churchgoers, regardless of denomination or religious tradition, were nearly five times more likely to oppose Death with Dignity than support it, holding all other variables constant. While the findings indicate a pattern of growth in support over the past 15 years, they indicate also a stability of opinion, with few individuals indicating they had changed their opinions about the issue since the first time they encountered it.
