Resumen
Esta pesquisa objetivou estudar a influência da calagem e de adubações minerais e orgânicas nas características químicas do solo, nos teores foliares de nutrientes, no crescimento do perímetro do tronco e na produção de frutos de tangerineiras 'Montenegrina' (Citrus deliciosa Tenore), enxertadas em Poncirus trifoliata Raf. O plantio foi realizado em julho de 1988, em solo podzolico vermelho-escuro, de textura franco-argilosa. Os tratamentos foram: 1- testemunha (sem adubação e sem catagem); 2- solo corrigido a pH 6,5 antes do plantio; 3- adubações com esterco de aves e calagens anuais; 4- adubações com esterco de bovinos e calagens anuais; 5- adubações com N, K e calagens anuais; 6- adubações com N, K, calagens anuais e correção com P antes do plantio; 7- adubações com N, P, K e calagens anuais; 8- adubações com N, P dose dupla, K e calagens anuais; 9- adubações com N, P e K, sem calagens anuais. Os resultados mostraram que os teores foliares de nutrientes, isoladamente, não são parâmetros suficientes para a recomendação de adubação. As adubações com N, P e K aumentaram os teores foiiares de M e não se refletiram na elevação dos teores de P e K. As adubações com N aumentaram o crescimento e a produção das plantas, mas proporcionaram maiores quantidades de frutos de qualidade inferior. Nas adubações com esterco de aves, o crescimento das plantas e a produção de frutos foram, em geral, equivalentes aos obtidos com as adubações minerais. A adubação com esterco de bovinos reduziu a produção total, mas aumentou a proporção de frutos de maior valor comercial. A adubação corretiva com P, antes do plantio, foi suficiente para assegurar uma produçáo de frutos similar as obtidas pelas adubações com reposição anual deste nutriente, ate oito anos após o plantio. As adubações com sulfato de amônio diminuíram o pH do solo.
The objectives of the present study were to investigate the influence of liming and mineral or organic fertization on the nutrients levels in soil and leaves, the increase of trunk perimeter and yields of 'Montenegrina' tangerines (Citrus deliciosa Tenore) grafted onto Poncirus trifoliata Raf. The orchard was planted in july, 1988 on a dark red podzolic (Rhodic Paleudult). The following treatments were applied: 1- control (without liming and fertilizers); 2- soil acidity corrected to pH 6,5 before planting; 3- annually hen's house litter manure and liming; 4- annually cattle manure and liming; 5- annually N and K fertilizers and liming; 6- annually N and K fertilizers and liming and P fertilizer before planting; 7- annually N, P and K fertilizers and liming; 8- annually N, K and double rate of P, and liming; 9- annually N, P and K fertilizers without liming. The results showed that levels of leaf nutrients alone are not an adequate parameter to be used fertization recommendation. Fertization with N, P and K increased leaf N contents and did not result in a increase in leaf P and K contents. N applications stimulated plant growth and increased total fruit production, but the fruits were of smaller size. The plants from the treatment that received hen's house litter manure resulted in plant growth and increased total fruit production equivalent of mineral fertilizers. On the other hand, plants fertilized with cattle manure, although having overal lower total fruit production, the tangerines were of better sizes compared to the treatments that received either mineral fertization or hen's house litter manure. Corrective applications of P before planting were sufficient to maintain adequate fruit production until eight years after planting. The nitrogen fertilizers caused soil acidification.

Resumen
Com o propósito de estudar a poda, o raleio de frutos e o uso de fitorreguladores para quebrar a alternância de produção e melhorar a qualidade físico-química dos frutos de tangerineiras ‘Montenegrina’ (Citrus deliciosa Tenore), enxertadas sobre laranjeira ‘Caipira’, em um pomar comercial de 6 anos, situado no município de Butiá-RS, realizouse dois experimentos. No primeiro, foram testados os seguintes tratamentos: A) Testemunha com planta de carga excessiva; B) Testemunha com plantas sem carga; C) Raleio manual de 66% dos frutos de plantas com carga excessiva; D) Pulverização de plantas excessivamente carregadas com 200 mg.L-1 de etefon; E) Poda de plantas excessivamente carregadas; F) Idem “E” + raleio manual de 33 % dos frutos; G) Idem “E” + pulverização com 50 mg.L-1 de 2,4-DP; H) Poda de plantas em alternância de produção (sem carga); I) Idem “H” + pulverização com 15 mg.L-1 de AG3. No outro experimento, testou-se o efeito de pulverizações de etefon nas concentrações de 200, 300, 400 mg.L-1 e Testemunha. Avaliou-se o número de frutos retidos e seu crescimento; número, massa e massa média dos frutos produzidos; qualidade química dos frutos; classificação dos frutos em primeira, segunda e terceira categoria; diâmetro e cor dos frutos e teor de substâncias de reservas das raízes. Verificou-se que a poda melhora a qualidade dos frutos, diminui o consumo de substâncias de reservas pela planta e reduz a produção de frutos de má qualidade e a alternância de produção. O raleio de 66% dos frutos de plantas excessivamente carregadas diminui a produção de frutos de má qualidade, mas é insuficiente para quebrar a alternância de produção, que só é conseguida associando-se a poda com o raleio manual de 33% dos frutos. O etefon só exerce efeito de raleio de frutos em pulverizações com concentrações superiores a 200 mg.L-1, porém eventuais benefícios são neutralizados pela ação fitotóxica revelada pelo amarelecimento e abscisão foliar. Na concentração de 10 mg.L-1, o AG3 não inibe diferenciação de gemas florais e a concentração de 50 mg.L-1 2,4-DP não aumenta o tamanho dos frutos.

Resumen
Após o descobrimento do ácido giberélico (AG3) em sementes de frutos, os pesquisadores começaram a aplicar ácido giberélico de maneira exógena em diferentes concentrações e épocas de aplicação com variados resultados. Um deles é a possibilidade de inibir a floração. A alternância de produção é um dos problemas mais importantes em algumas cultivares de cítricos, especialmente em tangerineiras com sementes. Com o objetivo de estudar a possibilidade de usar AG3 para inibir a diferenciação floral e controlar a alternância de produção, na Estação Experimental Agronômica da UFRGS, localizada no município de Eldorado do Sul - RS, num pomar com 20 anos de idade, 96 tangerineiras ‘Montenegrina’ (Citrus deliciosa Tenore) enxertadas sobre Poncirus trifoliata Raf., com desenvolvimento uniforme e em alternância de produção foram selecionadas e submetidas a pulverizações foliares em 2004, com as seguintes concentrações de AG3: 0. 20, 40 e 60 mg.L-1, nas épocas: 30 de abril, 20 de maio e 10 de junho. Nenhum tratamento inibiu a floração. O número e a massa dos frutos colhidos também não foram afetados. No ano 2005, os tratamentos foram repetidos nas mesmas concentrações e épocas de aplicação, atingindo frutos na fase de prématuração. A acidez total titulável (ATT) e a porcentagem de suco não foram afetadas pelos tratamentos. O teor de SST e a relação SST/ATT aumentaram linearmente com o incremento das concentrações de AG3, ao passo que a intensidade da cor amarelada da casca diminuiu, Observações histológicas de cortes longitudinais de gemas, feitos quinzenalmente desde 30 de abril a 30 de agosto, evidenciaram que a diferenciação floral, com emissão das primeiras sépalas ocorre em meados do mês de agosto.
After the discovery of gibberellic acid (GA3) in fruit’s seeds, researches began applying GA3 exogenously at different rates and timings with various results. Among them, inhibition of the flower bud differentiation. Alternate bearing is one of the most important problems of citrus cultivars, especially tangerines with seeds. The objetive of this work was to supress flower bud formation in light crop years and thereby reduce biennal bearing. In 2004, at the Estação Experimental Agronômica of the Universidade Federal do Rio Grande do Sul, located in Eldorado do Sul – RS, on a twenty-year-old orchard, 96 ‘Montenegrina’ (Citrus deliciosa Tenore) tangerine trees, grafted onto Poncirus trifoliata Raf. were rated as having a very light fruit load. The trees were sprayed with 0, 20, 40 or 60 mg.L-1 GA3.The foliar applications were made on April 30, May 20 and June 10. GA3 did not supress flowering of the trees. The number of fruits per tree and yield were not affected by the treatments regardless of treatments. In 2005, the experiment was repeated. The rates and timings of GA3 were the same, but were sprayed at the start of fruit color change. The treatments did not affect juice percent and acidity (TTA). GA3 rates increased total soluble solids (TSS) and TSS/TTA ratio and delayed the fruit degreening. Histological studies on bud longitudinal sections were realized every 15 days between April 30 and August 30. The period in which the vegetative buds are induced to flower bud with emission of the first sepals occurs on the first half of August.

Resumen
Italy is the birthplace of opera, and it provides a rich soil for the development of opera for centuries. In Italy, there are many masters who have or are making their own contributions to opera, including the great composers such as Verdi and Puccini and the outstanding singers like Caruso and Pavarotti. In the thesis, I will talk about the "living fossil" of the contemporary opera world - Angelo Loforese. In nearly 100 years of his artistic career, Loforese has devoted himself in vocal skills and education, and the inheritance of the artistic spirit. The thesis is divided into three chapters. The first chapter introduces the history of Italian opera and the relationship between opera and social background in each historical period, the historical development of tenor, and finally an overview of the career of Angelo Loforese. The second chapter is the translation from Italian to Chinese. I translated the first, third and twelfth chapter of Domenico Gullo's book "Angelo Loforese - il tenore con la valigia pronta sotto il letto". The book reviews the life of Loforese through dialogues and the author's memory. The third chapter is the translation commentary. In this chapter I use the “macroscopical -- microscopical” writing method. Firstly I analyze the genre of the original text, the target reader etc. Secondly I explain the problems that I’ve encountered when translating the text and the translation strategies used. In this chapter, I focus on combining the translation theories with practical examples.

Resumen
Questo lavoro di tesi è stato finalizzato alla messa a punto di polpette a ridotto tenore di carne avicola nelle quali sono stati utilizzati due diverse formulazioni contenenti vegetali (zucca/carota e spinaci) in grado di conferire caratteristiche peculiari. Sono state preparate 12 vaschette di polpette (6 per ognuna delle tipologie) confezionate in ATM (70% azoto e il 30% di CO2). I prodotti confezionati sono stati successivamente conservati in condizioni di refrigerazione (4 ± 1°C) per 14 giorni ed analizzati a diversi tempi di conservazione (T2, T4, T7, T9, T11 e T14). Per ogni confezione, 3 polpette sono state destinate alla misurazione del colore e della texture dopo averne determinato le perdite di peso per cottura e le restanti 3 utilizzate allo scopo di misurare l’aw ed il pH. È stata inoltre condotta (al giorno T3) un’analisi sensoriale mediante panel test volta a definire il livello di gradevolezza dei prodotti. Dall'esame dei risultati è possibile evidenziare che gli ingredienti aggiunti nell’impasto hanno consentito di ottenere livelli di perdite di cottura e proprietà strutturali, quali coesività ed elasticità, soddisfacenti in entrambi i prodotti. Le prove di assaggio hanno mostrato un buon gradimento sia per l’aspetto che per le proprietà gustative. Dal confronto fra i due prodotti, è emerso che le polpette contenenti spinaci sono dotate di un pH significativamente maggiore rispetto a quelle con zucca e carota in relazione alla diversa acidità dei vegetali impiegati. Per quanto concerne il colore, il campione formulato con zucca e carote non ha mostrato variazioni significative durante la conservazione refrigerata, al contrario le polpette contenenti spinaci hanno presentato una variazione di colore piuttosto marcata in grado di comprometterne l’accettabilità. Anche per quanto riguarda la texture, le polpette contenenti zucca e carote hanno evidenziato una maggiore stabilità lungo tutto il periodo di conservazione.

Resumen
O estudo teve como objetivo o inventariamento da comunidade de artrópodes predadores presentes em um pomar orgânico de Citrus deliciosa Tenore, var. Montenegrina (29º37’51”S e 51º28’10”W), situado no Município de Montenegro, Rio Grande do Sul, Brasil. As amostragens foram realizadas quinzenalmente, de 29 de março de 2004 a 14 de março de 2005. Em cada uma das ocasiões, de 24 plantas sorteadas, era retirada uma unidade amostral de ambas as faces da copa voltadas para as entrelinhas, totalizando 48 unidades por ocasião, utilizando-se um pano-de-batida de 1m2. As 26 ocasiões de amostragem resultaram na captura de 3.787 artrópodes predadores, dos quais 3.129 pertencentes a Arachnida e 658 a Insecta, distribuídos num total de 112 espécies. Leptus sp. 1 (Acari: Erythraeidae), Amblyseius saopaulus Denmark & Muma (Acari: Phytoseiidae) e Camponotus sp.1 (Hymenoptera: Formicidae) foram as espécies mais abundantes. Com base nos adultos de Araneae, foram reconhecidas 53 espécies distribuídas em oito famílias; em Acari, considerando jovens e adultos, registraram-se oito espécies em três famílias e em Insecta constataram-se indivíduos das ordens Coleoptera, Hymenoptera, Neuroptera, Thysanoptera e Hemiptera, perfazendo dez famílias e 51 espécies. Com relação à sazonalidade, os artrópodes foram mais abundantes no inverno (521 indivíduos) e a maior riqueza foi verificada durante a primavera, com 76 espécies. Considerando apenas os aracnídeos, o inverno foi a estação que apresentou maior abundância de indivíduos (42,1%), enquanto a primavera foi a mais rica em número de espécies (41). Quanto aos índices de diversidade nesse grupo, Margalef foi mais elevado na primavera e Shannon-Wiener e Simpson no verão. Em relação aos insetos, a maior abundância (29,3%) e riqueza (35) foram verificadas na primavera, assim como os maiores valores de Shannon-Wiener e Margalef; já os de Simpson foram semelhantes entre as estações. Tais registros evidenciam a grande diversidade de artrópodes predadores neste agroecossistema e fornecem subsídios para o manejo e a conservação destas espécies.
The study aimed to survey the community of predatory arthropods in an organic orchard of Citrus deliciosa Tenore, var. Montenegrina (29º37’51”S and 51º28’10”W), located in Montenegro County, Rio Grande do Sul, Brazil. Samplings were carried out fortnightly, from March 29th, 2004 to March 14th, 2005. At each sampling occasion, a sample was taken from each one of 24 randomly selected trees, at both sides of the canopy facing the inter-rows. Henceforth, 48 sampling units/occasion were obtained shaking a branch of the plant with a wood stick and collecting the arthropods that fell on a sheet of white cloth (1m2) laid under the canopy tree. The 26 sampling occasions rendered 3,787 individuals of predatory arthropods, 3,129 belonging to Arachnida and 658 to Insecta, distributed in 112 species. Leptus sp. 1 (Acari: Erythraeidae), Amblyseius saopaulus Denmark & Muma (Acari: Phytoseiidae) and Camponotus sp.1 (Hymenoptera: Formicidae) were the most abundant species. Based upon the adults, 53 species of Araneae were recognized, belonging to eight families. Among Acari, considering immatures and adults, eight species were recorded in three families. In Insecta, it was found individuals of the Orders Coleoptera, Hymenoptera, Neuroptera, Thysanoptera e Hemiptera, amounting to ten families and 51 species. Arthropods were most abundant in winter (521 individuals), whereas the greatest richness was verified during spring, attaining 76 species. Considering only arachnids, individuals were more abundant in winter (42.1%), meanwhile the greatest richness was registered in spring (41 species). Relative to the diversity indices, in this group, Margalef was higher in spring, and Shannon-Wiener and Simpson in the summer. Relative to insects, both abundance (29.3%) and richness (35 species) were more elevated in spring, as well as the values of Shannon- Wiener and Margalef. Nevertheless, the Simpson’s values were similar among seasons. These findings evidence the high diversity of predatory arthropods occurring in this agroecosystem and furnish clues to the management and conservation of these species.

Resumen
Il presente lavoro si propone quale contributo allo studio della determinazione del reddito imponibile complessivo delle persone fisiche a partire dal tenore di vita da esse manifestato. Il quadro di riferimento è quello del novellato art. 38 del d.p.r. n. 600/1973, il quale contempla due differenti metodi di accertamento (il “sintetico” e il “sintetico-redditometrico”). Il tratto caratterizzante degli stessi è dato dal fatto che, in entrambi i casi, ci troviamo al cospetto di metodi i quali si disinteressano delle fonti di produzione del reddito e valorizzano, per contro, situazioni caratterizzate dal sostenimento di spese di carattere personale o familiare giudicate abnormi rispetto al dichiarato.
The aim of this paper is to give a contribution to the study of the administrative determination of the individuals’ total taxable income, using their living standard as a starting point. The legal framework is that of the novel art. 38 of Presidential Decree nr. 600 of 1973, which provides for two different methods of tax assessment (the “synthetic” and the “redditometro”). The distinguishing feature of these assessment methods is that they are not focused on income sources. On the contrary, they emphasize situations occurring when income is used to cover personal or family expenses that seemingly exceed the amount of taxable income declared in the tax return.

Resumen
Al giorno d’oggi la principale preoccupazione degli italiani riguarda la perdita del lavoro e del proprio tenore di vita. Liberi professionisti e lavoratori autonomi hanno una preoccupazione in più: il loro tenore di vita può essere compromesso non solo dalla perdita del lavoro per contingenze di mercato, ma anche a causa di infortuni e malattie. In Italia, però, solo il 23% della popolazione ha una polizza infortuni e solo il 9,4% ha una polizza malattia: questi dati evidenziano il fatto che tra la popolazione del nostro paese vi sia una bassa percezione del rischio, oltre ad una percezione di adeguata tutela da parte del welfare state. In realtà le prestazioni dello stato sociale raramente sono adeguate alle esigenze di tutela dell’individuo e questo può ridurre di molto la qualità della vita del singolo o della famiglia. Il mercato assicurativo propone molte soluzioni per la tutela dell’individuo in caso di infortunio o malattia: l’assicurazione può essere ritenuta lo strumento principale per la gestione del rischio nella famiglia in quanto trasforma l’incertezza del sinistro in un costo conosciuto, il premio di polizza, e permette di disporre dei propri risparmi senza la preoccupazione di riservarne parte per la tutela del tenore di vita proprio e dei familiari.

Resumen
Since the first half of the 20th century, the incidence of Multiple Sclerosis (MS), Type 1 Diabetes (T1D) and Autism Spectrum Disorders (ASDs) has increased in Sardinia. T1D results from autoimmune destruction of insulin, producing beta cells of the pancreas; MS is a chronic disease of the central nervous system, causing neurological affliction; Autism is defined as a complex developmental disability that generally appears during the first three years of life. Concerning MS and T1D, Sardinia island has one of the highest incidence rate in the world. In this island, there is the presence of phenotypes of these diseases, due to the homogeneous genetic background of the local population. Indeed, Sardinia population is a genetic isolate. The genetic background by itself does not explain such increasing incidence. T1D and MS increase with latitude, but Sardinia is an exception. Furthermore, mining exploitation was one of the most important economic activities in Sardinia during the past centuries and a lot of data are today available for the researchers. For this reasons Sardinia is an ideal setting to study a possible correlation between environmental factors and the diseases above, because of sardinian people genetic background and environmental peculiarities of the island. A set of environmental data and the frequency data of MS, T1D and ASD were investigated to evaluate the correlation between environmental factors and the frequency of these diseases. In particular, among the environmental factors, geochemical data are included in the Geochemical Database of the Department of Civil, Environmental Engineering and Architecture (DICAAR) of the Cagliari University. This Database is populated by thousands of data concerning soils, rocks and stream sediments. A stream-sediment-type sampling, which is widely used for mineral prospecting, has the advantage of effectively representing the overall geochemical print of a wide portion of territory such as a stream basin. Environmental and diseases data were analyzed through the statistical methods which were used by mining prospections activities. Environmental factors considered in this study are: geochemical values of each lithology, lithology and geology, sun exposure and climate. Also spatial analysis distribution of MS, T1D and ASDs was done. Therefore, a correlation between the environmental factors in reference to the total population and the frequency of the diseases was evaluated. Moreover, the correlation between the environmental factors in both male and female population and the frequency of the diseases was investigated. In a first time these relationships were investigate for each municipalities. Afterwards, 109 Homogeneous Areas (HA) from lithological point of view were identified. Each Homogeneous Area includes one or more municipalities, which have the same lithological features. Then, the relationship between the environmental factors and the frequency of diseases was evaluated for each HA. About T1D analyses, they revealed negative associations between the incidence of the disease and some elements, such as Cu (r = -0.349, Pvalue = 2*10-4) and Zn (r = -0.332, Pvalue = 4.20*10-4), while, concerning MS, a mild correlation was present between Cu (r = -0.460, Pvalue = 1*10-3) and the distribution of the disease in the male gender. A significant correlations was calculated among Pb (r = 0.478, Pvalue = 3.43*10- 6), Cd (r = 0.412, Pvalue = 8.10*10-5), Zn (r = -0.378, Pvalue = 3.3*10-4) and the presence of ASDs. In this research was used for the first time a geo-epidemiological approach to identify environmental factors involved to the geographical distribution of above diseases. Moreover, the elements significantly correlated with MS, T1D and ASDs could be markers (pathfinders) of other elements not analyzed in this study (confounding), but they could be potentially involved on the onset of the diseases. Also, our results should be considered as hypothesis-generating rather than hypothesis testing study. This kind of study is unusual and it has a deep interdisciplinary approach so the present results must be better confirmed in future studies.

Brazil is one of the largest fruit producers in the world and Rio Grande do Sul is the third largest producer of tangerines, housing the city of Montenegro as the fifth largest in the state. Some species of insects can transmit the bacterium Xylella fastidiosa that causes disease Citrus Variegated Chlorosis (CVC), so this study presents the communities of Cicadellidae, Membracidae and Cercopidae. The last family of insects, in turn, maintain biological associations with ants attendants beneficial to the host plant because the ants protect against external herbivores. In addition, the population fluctuation of the fruit fly Anastrepha fraterculus (Wiedemann, 1830) was investigated through its relationship with abiotic data. Therefore, the objectives of this work were to study the diversity, identify species potential vectors of X. fastidiosa, investigate the population fluctuation and to know the species membracids to control the action of other harmful herbivores to citrus. The diversity of insects in orchards intercropped and not intercropped with spontaneous vegetation under organic management was compared. We selected four citrus orchards of Citrus deliciosa, two intercropped and two not intercropped orchards with natural vegetation of a private property of that municipality. The capture of specimens was performed biweekly from August 2009 to July 2010, using yellow sticky traps, sweep-network and yellow tray of water.The Shannon diversity index (H’) and Simpson (D), obtained through the program Ecological Methodology, constant rates, collector’s curve and richness estimators (Bootstrap, Chao 2, Jackknife 1 and 2), obtained through the program Past version 2. 09 were used for data analysis. We captured 4. 841 Cicadellidae, distributed in 17 genera and 23 species and 57 Cercopidae, two genera and two species. The months of greater diversity of leafhoppers in both orchards, intercropped and not intercropped were in December 2009 (H’= 2,86; D= 0,78), March (H’= 3,02; D= 0,84) and April 2010 (H’= 3,27; D= 0,87). The leafhoppers Sibovia sagata, Macugonalia cavifrons, M. leucomelas, Hortensia similis, Tapajosa rubromarginata and Oncometopia facialis were considered potential vectors of the pathogen. We captured 1. 200 Membracidae, distributed in three subfamilies, 13 genera and 18 species. Smiliinae had the highest abundance of 751 (62. 58%) and richness, 10 species. The months of greater diversity of treehoppers in intercropped orchards were in August, November 2009 and May 2010, and in not intercropped were in April and May 2010. Cyphonia clavata, Tolania sp. and Micrutalis sp. were considered a constant species.The richness of treehoppers in orchards intercropped was 17 species, eight of them unique, and in not intercropped orchards was 10 species, with only one unique. The collector’s curves and richness estimators for leafhoppers and trehoppers demonstrated that sampling effort was satisfactory, since that were collected around 80% of species expected by indexes. The total number of flies collected was 391, 109 in intercropped orchards and 283 in not intercropped. The peak population of A. fraterculus in intercropped orchards were in September and December 2009, January and May 2010, in not intercropped were September, November and December 2009 and February and May 2010. Regarding temperature, the months of highest occurrence was in December 2009 and May 2010 due to the drier season and the maturity of the fruits of C. deliciosa, respectively.

Os cicadelídeos Sibovia sagata, Macugonalia cavifrons, M. leucomelas, Hortensia similis, Oncometopia facialis e Tapajosa rubromarginata foram consideradas potenciais vetoras do patógeno. Foram capturados 1. 200 membracídeos, distribuídos em três subfamílias, 13 gêneros e 18 espécies. Smiliinae apresentou a maior abundância de 751 (62,58%) e riqueza, 10 espécies. Os meses de maior diversidade de membracídeos em pomares consorciados foram agosto, novembro de 2009 e maio de 2010, já nos não consorciados foram abril e maio de 2010. Cyphonia clavata, Tolania sp. e Micrutalis sp. 1 foram consideradas espécies constantes.A riqueza de membracídeos em pomares consorciados foi de 17 espécies, sendo oito exclusivas dos mesmos, já em pomares não consorciados a riqueza foi de 10 espécies, com apenas uma exclusiva. As curvas de coletor e os estimadores de riqueza para as cigarrinhas e membracídeos demonstraram que o esforço amostral empregado foi satisfatório, visto que foram coletadas em torno de 80% das espécies esperadas pelos índices. O número total de moscas coletadas foi de 391, sendo 109 em pomares consorciados e 283 em não consorciados. Os picos populacionais de A. fraterculus em pomares consorciados foram em dezembro e setembro de 2009, janeiro e maio de 2010, já em não consorciados foram em setembro, novembro e dezembro de 2009 e fevereiro e maio de 2010. Em relação à temperatura, os meses de maior ocorrência foram dezembro de 2009 e maio de 2010, devido à estação mais seca e à maturação dos frutos de C. deliciosa, respectivamente.

Texto completo
Resumen
Selon millet et al. (1991) la rythmicite infradienne rencontree dans l'elongation de la tige des plantes herbacees et ligneuses pourrait resulter d'un battement entre un rythme dont la periode serait d'exactement 24 heures, qui aurait son siege dans la tige, et qui serait synchronise par les variations des facteurs de l'environnement en regime d'eclairement et de temperature alterne (ld : 14/10) et un autre, de periode legerement differente de 24 heures, s'exprimant dans les parties souterraines de la plante placees en conditions de quasi libre-cours. Chez les plantes cultivees en regime d'eclairement continu (ll), a temperature constante, la tige cesse dans la plupart des cas de s'allonger. Lorsque l'elongation se poursuit, aucune rythmicite infradienne ne se manifeste. En regime ld, la rythmicite infradienne s'exprime normalement. La periode est comprise entre 36 et 54 jours. Ce resultat laisse supposer qu'en libre-cours, les deux rythmes circadiens ont meme periode et qu'il n'y a pas de battement, contrairement a ce qui se passe en regime ld. En regime ld, le flux de seve dans la racine et dans la tige s'annule la nuit et passe par un maximum le jour. Apres transfert en conditions constantes, le rythme persiste quelques jours avec une periodicite circadienne, mais sensiblement differente dans la tige et dans la racine, puis s'amortit. Lorsque la transpiration est supprimee, le rythme circadien du flux de seve est aboli dans la tige mais subsiste dans la racine. Une correlation positive existe entre le flux de seve et les quantites d'eau et d'ions contenus dans les differents organes de la plante. Alors que la periode de l'absorption de l'eau est d'exactement 24 heures en regime ld, celle de l'absorption du k#+ et du mg#2#+ est un peu superieure a 24 heures. Apres transfert en regime ll, la periode s'allonge sensiblement pour l'eau et se raccourcit pour les ions. Huit jours apres le transfert, la rythmicite est abolie. Les deux oscillateurs circadiens pourraient etre le fonctionnement stomatique pour les parties aeriennes et le mecanisme d'absorption pour le systeme racinaire. Cette proposition est discutee en faisant reference aux travaux d'autres auteurs.

Resumen
Data with rich spatial information are commonly acquired in the real-world. These data are often represented by multi-way arrays, i.e., tensors. For those also with temporal information, they can be sketched as tensorial time series. Tensorial data, including tensorial time series are closely related to “big data”, because they are often with the “4V” features where data are in the large volumes and variety, require the high velocity to process them and can be with veracity caused by outliers, noises, missing values, etc., in practice. Existing methods either flatten tensors into vectors or impose strong assumptions. The former can cause the extreme large number of parameters and fail to process large volume data with the high velocity, whereas the latter cannot effectively deal with the challenge from the veracity and variety. This thesis consists of three topics which can form a pipeline to analyse tensorial data, including tensorial time series, with efficacy and other desired characteristics, to address the “4V” features. Firstly, for data preprocessing, we proposed a dimensionality reduction model Tensor-Train Parameterisation for Ultra Dimensionality Reduction (TTPUDR) specifically for ultra-dimensional data which are converted from tensors. Also, they have dimensions larger than the number of samples, which violates the assumption of many past methods. TTPUDR efficiently and effectively captures complicated spatial information in these data, avoids the curse-of-dimensionality problem and copes with extreme outliers. In the second and the third topics, we proposed a series of tensor neural differential equations to exploit complicated nonlinear spatial and temporal information for tensorial time series prediction, including irregular ones with unequally-spaced time steps which violate the equidistance assumption on time steps of many existing methods. For models proposed in all three topics, their efficacy is proved with theoretical guarantees. In numerical experiments, all proposed models outperform the existing models and demonstrate their efficiency and effectiveness on complicated spatial information and/or temporal information analysis in tensorial data, including tensorial time series.

Resumen
This master's thesis addresses numerical methods of computing the typical ranks of tensors over the real numbers and explores some properties of tensors over finite fields. We present three numerical methods to compute typical tensor rank. Two of these have already been published and can be used to calculate the lowest typical ranks of tensors and an approximate percentage of how many tensors have the lowest typical ranks (for some tensor formats), respectively. The third method was developed by the authors with the intent to be able to discern if there is more than one typical rank. Some results from the method are presented but are inconclusive. In the area of tensors over nite filds some new results are shown, namely that there are eight GLq(2) GLq(2) GLq(2)-orbits of 2 2 2 tensors over any finite field and that some tensors over Fq have lower rank when considered as tensors over Fq2 . Furthermore, it is shown that some symmetric tensors over F2 do not have a symmetric rank and that there are tensors over some other finite fields which have a larger symmetric rank than rank.

Resumen
In many applications that deal with high dimensional data, it is important to not store the high dimensional object itself, but its representation in a data sparse way. This aims to reduce the storage and computational complexity. There is a general scheme for representing tensors with the help of sums of elementary tensors, where the summation structure is defined by a graph/network. This scheme allows to generalize commonly used approaches in representing a large amount of numerical data (that can be interpreted as a high dimensional object) using sums of elementary tensors. The classification does not only distinguish between elementary tensors and non-elementary tensors, but also describes the number of terms that is needed to represent an object of the tensor space. This classification is referred to as tensor network (format). This work uses the tensor network based approach and describes non-linear block Gauss-Seidel methods (ALS and DMRG) in the context of the general tensor network framework. Another contribution of the thesis is the general conversion of different tensor formats. We are able to efficiently change the underlying graph topology of a given tensor representation while using the similarities (if present) of both the original and the desired structure. This is an important feature in case only minor structural changes are required. In all approximation cases involving iterative methods, it is crucial to find and use a proper initial guess. For linear iteration schemes, a good initial guess helps to decrease the number of iteration steps that are needed to reach a certain accuracy, but it does not change the approximation result. For non-linear iteration schemes, the approximation result may depend on the initial guess. This work introduces a method to successively create an initial guess that improves some approximation results. This algorithm is based on successive rank 1 increments for the r-term format. There are still open questions about how to find the optimal tensor format for a given general problem (e.g. storage, operations, etc.). For instance in the case where a physical background is given, it might be efficient to use this knowledge to create a good network structure. There is however, no guarantee that a better (with respect to the problem) representation structure does not exist.

Resumen
The purpose of this study is to examine the Tennessee tenure law by comparing the overall level of effectiveness of teachers who received tenure prior to receiving tenure and the overall level of effectiveness of teachers after receiving tenure. The population of this study includes teachers from districts in the Mid Cumberland region in Tennessee who received tenure after 2012. The major finding of this study was the effectiveness of teachers who received tenure under the current tenure law in Tennessee did not significantly change for up to two years after they received tenure. The lone exception was high school teachers. Their effectiveness significantly declined two years after receiving tenure. This study concluded that the current tenure law in Tennessee had components of effective policies as found in research and had safeguards in place to ensure only effective teachers were awarded tenure.

Resumen
Using feedback scores from an established upward feedback program, the role of gender interactions, company tenure, and job tenure on leadership ratings of managers by subordinates were examined. Four separate analyses were conducted: a 2 X 2 ANOVA, a 2 X 6 ANOVA, and two Aptitude-Treatment Interaction (ATI) regression analyses in accordance with the procedure set forth in Pedhazur (1997). No significant main effects or interactions were found for manager gender and subordinate gender on ratings of managers. Manager company tenure had a significant effect on ratings of managers, R = .002, F (1, 168) = .53, p < .05, but manager job tenure was not found to have a significant effect on manager ratings. Subordinate company tenure also had a significant effect on manager ratings, F (5, 3973) = 5.95, p < .01. A post-hoc Scheffe's test indicated significant differences were shown between subordinates whose tenure was 6 months to 1 year and 1 to 3 years versus subordinates whose tenure was greater than 10 years, p < .05. The need for further research of factors that may influence upward feedback ratings was emphasized; limitations of the study were also discussed.

Linear filtering methods are well known and have been successfully applied to many engineering problems. However, they become unpractical when the parameter space is very large. The recently proposed assumption of system separability allows the development of computationally efficient alternatives to classical filtering methods in this scenario. In this work, we show that system separability calls for multilinear system representation and filtering. Based on this parallel, the proposed filtering framework consists of a multilinear extension of the classical Wiener-Hopf (WH) filter that exploits the separability property to solve the supervised multilinear filtering problem. System identification and antenna beamforming computer simulations were conducted to assess the performance of the proposed method. Our numerical results show our approach has smaller computational complexity and that it provides better estimation accuracy than the classical WH filter, which ignores the multilinear system structure.
Métodos de filtragem linear estão bem estabelecidos e têm sido aplicados em diversos problemas de engenharia. Entretanto, eles tornam-se impraticáveis quando o espaço de parâmetros é grande. A recente hipótese de separabilidade de sistema permite o desenvolvimento de métodos computacionalmente eficientes neste cenário. Neste trabalho, nós mostramos que a separabilidade de um sistema leva à sua representação multilinear. Em vista disso, o método de filtragem proposto consiste em uma extensão multilinear do filtro de Wiener-Hopf (WH) clássico, que explora a separabilidade para resolver o problema de filtragem multilinear supervisionada. Simulações computacionais de identificação de sistemas e formatação de feixes de antenas foram realizadas para a avaliação do desempenho do método proposto. Nosso resultados numéricos mostram que nossa abordagem possui menor complexidade computacional e que ela fornece melhor acurácia de estimação que o filtro de WH clássico, que ignora a estrutura multilinear do sistema.

Resumen
This study explored attitudes of occupational therapy faculty toward tenure and selected alternatives to tenure. A survey method was employed, and the Tenure Attitude Survey Instrument, (TASI), was created for use in the study. Additionally, a questionnaire sought information regarding respondents' rank, tenure and administrative status, institutional type, and years in academia. Participants were accredited occupational therapy professional program faculty who identified their primary work setting as "Academic" on the 2000-2001 American Occupational Therapy Association membership survey. Factor analysis of 577 surveys examined the structure of scores on the TASI, and the instrument consisted of 4 scales, and 18 items, as follows: Scale One: Attitude toward academic freedom and job security protection, 7 items; Scale Two: Attitude toward tenure in general, 6 items; Scale Three: Attitude toward stop-the-tenure clock provisions, 2 items; and Scale Four: Attitude toward post-tenure review, 3 items. Cronbach's alpha was conducted, as follows: TASI overall alpha = .7915; Scale 1 alpha = .7884; Scale 2 alpha = .8420; Scale 3 alpha = .7020; Scale 4 alpha = .4229. Proportional analysis showed that most respondents were full time faculty (88.1%); taught full time at public institutions (52.8%); were tenured or tenure-track (55.5%); had no administrative duties (70.5%); with a rank of instructor or lecturer (17.5%), or assistant professor (45.7%). Time in academia ranged from 1-40 years, with a mean of 11.27 years, median of 9.25 years, and mode of 4 years. Attitudes toward, and support for, the continuation of tenure and for selected proposed alternatives to tenure were analyzed according to the following: faculty rank, administrative status, and tenure status. Respondents held generally favorable attitudes toward tenure as measured by Scales 1 and 2 of the TASI, and the best predictors of faculty attitude toward tenure were tenure status and rank. Due to low reliability scores on Scales 3 and 4, no conclusions can be drawn regarding respondents' attitudes toward alternatives to tenure.

Webb, Adam Michael. "Art songs for tenor : a pedagogical analysis of art songs for the tenor voice". Diss., University of Iowa, 2012. https://ir.uiowa.edu/etd/3401.

Texto completo
Resumen
The purpose of this project is to assist voice teachers in training tenors by selecting forty art songs that are pedagogically useful in the training of the tenor voice, and providing specific pedagogical strategies for the learning process of the selected repertoire. The list of repertoire consists of ten art songs from each of the four main Western singing languages: Italian, English, German, and French. These four languages have been selected because they represent the vast majority of standard art song repertoire for the typical undergraduate tenor. What is missing in current literature, and what this project addresses, is a pedagogically focused analysis of carefully chosen set of art song repertoire for the tenor voice. This project aids teachers and young tenors in technique and repertoire selection by identifying technical issues in each song, explaining ways to approach those technique issues, and highlighting positive pedagogical results from learning each song. By following the strategies set forth in this project, the tenor and teacher will be better equipped to select appropriate art song repertoire beyond those songs presented in this project and address vocal technique through the song learning process. The body of the dissertation begins with a discussion of pedagogical areas in which the tenor's technique is most distinct from other voice parts including: passaggio, vowel modification, appoggio, giro, chiaroscuro, tessitura, and agility. A brief introduction of each song will include stylistic information on the piece and analysis of the song including range, tessitura, level of difficulty, and vocal demands. I will then discuss specific examples of difficult melodic passages, or phrases that are of pedagogical value and offer specific exercises that can aid the tenor in the song learning process. The information discussed in each song provides a starting point for further repertoire selection beyond this project by introducing the teacher and tenor to composers, collections, or cycles that logically supplement the list of selected repertoire.

Resumen
In academia, after a reasonable probationary period of service and upon the achievement of tenure, the recipients of tenure are entitled to a continuing appointment at an institution without mandatory retirement and with only limited grounds for revocation. Advocates of tenure argued that it protected academic freedom through economic security. Opponents of tenure argued that it fostered inefficient and unproductive behavior. This dissertation developed a framework for examining academic tenure in U.S. economics departments. I constructed a dataset of tenured U.S. economics professors who were Ph.D. recipients between 1990 and 2006 and tracked their publications. In the first chapter, based on difference-in-difference analysis I found that tenure has a direct effect on the choice of research direction/focus. In general, tenured groups had a higher degree of specialization than non-tenured groups after they received tenure. For some tenured groups, even if their extent of specialization decreased after tenure, when I controlled for unobserved heterogeneity, tenure still had a positive effect on extent of specialization. This result suggested that the job security provided by tenure made tenured faculty more narrowly focused on their research. Using path analysis in the second chapter, my finding suggested that the extent of specialization was one of the key factors which might influence a scholar’s productivity. In addition, the extent of specialization helped explain gender differences in academic productivity. The results revealed that the effect of gender on productivity through the degree of specialization was more notable among older generations, and in most fields, gender differences in extent of research specialization mediated gender difference in research performance; although there were some fields in which gender difference in the research process could not explain gender difference in research performance. The third chapter expanded our understanding of advancement in academics by exploring a new dimension of inquiry: whether the extent of specialization in scholars’ research programs improved promotion prospects. Using discrete event analysis, my research showed that the extent of research specialization contributed to career acceleration, although gender difference on the prospects of advancement in academics was not significant.

Resumen
Urban areas in Ethiopia have been growing very quickly in recent decades, which haveled to ever increasing demand for land in peri-urban areas for housing and other nonagriculturalactivities. This has had several transformative impacts on the transitionalperi-urban, areas including engulfment of local communities and conversion of landrights and use from an agricultural to a built-up property rights system. Peri-urban areasalso display all forms of competition for land among people of diverse backgrounds.Research on the challenges of urbanization in peri-urban land tenure system and theongoing changes in Ethiopia is limited, and the situations and actors interested in periurbanland are constantly changing. Therefore, the purpose of this research is toinvestigate the challenges imposed on peri-urban land rights as a result of the growingdemand for land for urbanization. The project also encompasses an attempt to discoverthe process of informal transaction and development of peri-urban land and the principalactors involved. The study comprises a summary essay and four articles which were conducted using casestudy and desk review research approaches. Following the case study tradition, acombination of different data collection instruments such as questionnaires, FGDs, keyinformant interviews (both structured and open-ended) and direct field observations wasemployed to collect research data from the case study areas. Bahir Dar CityAdministration was selected purposively as case study area at the first stage and two periurbanvillages, Weramit and Zenzelima, were selected from Bahir Dar CityAdministration at the second stage of the case study area selection process. The research has revealed that urbanization and urban development in Ethiopia areaccompanied by contentious land tenure changes which favor the urbanities above localperi-urban communities. As a result, urbanization has precipitated a wave ofdispossession and proliferation of informal settlements in peri-urban areas. Thus,addressing the challenges of urbanization and its effect on the land rights of local periurbancommunities requires the introduction of an inclusive and participatory landdevelopment tool like land readjustment, which can encourage voluntary contribution ofland for urbanization by the local peri-urban landholders themselves.

Bibliography
ABSTRACT ENGLISH: The dissertation considers the tenure rights of urban residential tenants in the post-1994 constitutional dispensation. The 1996 Constitution mandates tenure reform in two instances. Firstly, section 25(6) (read with section 25(9)) mandates the legislature to enact legislation that would provide legally secure tenure rights for a person or community whose tenure of land is insecure as a result of past racially discriminatory laws or practices. This form of tenure reform is race-based. Secondly, section 26(3) mandates the courts to consider all relevant circumstances during eviction proceedings. In terms of this provision the court can refuse to grant the eviction order on the basis of the occupier's socio-economic weakness, which is a more general form of class-related tenure reform. The Constitution also ensures the right to have access to adequate housing, while the legislature must introduce measures that would give effect to this right (sections 26(1) and 26(2)). To determine whether the current landlord-tenant regime in South Africa is able to provide tenants with secure occupation rights and access to rental housing, it is compared to landlord-tenant regimes in pre-1994 South Africa, the United Kingdom, New York State and Germany. The landlord-tenant regimes are considered in light of changing socio-economic circumstances where the state had to assist households during housing shortages. The dissertation assesses the efficiency of landlord-tenant law, combined with regulatory measures that ensure substantive tenure rights and rent restrictions, as a form of tenure that could help alleviate housing shortages and initiate a new landlord-tenant regime for South Africa that would give effect to the Constitution. The dissertation concludes that the current substantive tenure rights of urban residential tenants are largely based on the common law, which is associated with weak tenure security. The landlord-tenant laws, namely the Rental Housing Act 50 of 1999 and the Social Housing Act 16 of 2008, fail to provide urban residential tenants with substantive tenure rights. The legislature has failed to enact a law that gives effect to section 25(6) in the landlord-tenant framework. The legislature did enact the Prevention of Illegal Eviction from and Unlawful Occupation of Land Act 19 of 1998 (PIE) in order to give effect to section 26(3). Recently the courts interpreted PIE to provide marginalized tenants with substantive tenure protection during eviction proceedings. However, to give effect to section 25(6) legislation should grant residential tenants substantive tenure rights that are legally secure prior to eviction. The legislature enacted the Rental Housing Act and the Social Housing Act to give effect to the right to housing (section 26 of the Constitution) in the landlord-tenant framework. These laws fail to promote access to rental housing as a form of tenure that could help alleviate housing shortages.
AFRIKAANSE OPSOMMING: Die proefskrif oorweeg die okkupasieregte van stedelike residensiële huurders in die post-1994 konstitusionele bedeling. Die 1996 Grondwet bepaal dat okkupasieregte in twee gevalle hervorm moet word. Eerstens gee artikel 25(6) (gelees met artikel 25(9)) opdrag aan die wetgewer om wetgewing te verorden wat okkupasieregte met verblyfsekerheid aan 'n person of gemeenskap sal verleen indien so 'n person of gemeenskap tans grond okkupeer met okkupasieregte wat onseker is as gevolg van vorige rasgebaseerde wetgewing. Hierdie tipe hervorming is rasgebaseer. Tweedens gee artikel 26(3) opdrag aan die howe om alle relevante faktore te oorweeg as deel van enige uitsettingsprosedure. In terme van hierdie bepaling is die howe gemagtig om 'n uitsettingsbevel te weier op die basis van die okkupeerder se sosio-ekonomiese kwesbaarheid. Hierdie tipe hervorming is 'n meer algemene klasgebaseerde hervorming. Artikel 26(1) (gelees met artikel 26(2)) van die Grondwet bepaal dat elkeen die reg op toegang tot geskikte behuising het, terwyl die staat redelike wetgewende en ander maatreëls moet tref om hierdie reg te verwesenlik. Ten einde te bepaal of die huidige huurbehuisingstelsel in Suid-Afrika voldoende is, met inagneming van die stelsel se vermoë om huurders te voorsien van okkupasieregte met verblyfsekerheid en van toegang tot huurbehuising, word dit vergelyk met die huurbehuisingstelsels in Suid Afrika voor 1994, die Verenigde Koninkryk, New York Staat en Duitsland. Hierdie huurbehuisingstelsels word bespreek met inagneming van veranderinge in die sosio-ekonomiese omstandighede waartydens die staat gedurende behuisingstekorte huishoudings moes ondersteun. Die doeltreffendheid van huurbehuising word beoordeel met verwysing na regulasies wat substantiewe okkupasieregte verseker en beperkings plaas op huurpryse om 'n vorm van verblyfreg daar te stel wat die behuisingstekort kan verminder ten einde 'n nuwe huurbehuisingstelsel vir Suid-Afrika te inisieër wat gevolg aan die Grondwet sal gee. Die proefskrif lei tot die gevolgtrekking dat die huidige substantiewe okkupasieregte van stedelike residensiële huurders grotendeels op die gemenereg gebaseer is. Die gemenereg maak nie voorsiening vir sterk substantiewe okkupasieregte nie. Die huidige huurbehuisingswetgewing, naamlik die Wet op Huurbehuising 50 van 1999 en die Wet op Maatskaplike Behuising 16 van 2008, slaag nie daarin om substantiewe okkupasieregte vir stedelike residensiële huurders te voorsien nie. Die wetgewer het nie daarin geslaag om 'n wet te promulgeer wat in die huurbehuisingsraamwerk aan artikel 25(6) effek gee nie. Die wetgewer het wel die Wet op die Voorkoming van Onwettige Uitsetting en Onregmatige Besetting van Grond 19 van 1998 verorden om effek te gee aan artikel 26(3) van die Grondwet. Hierdie Wet is onlangs so deur die howe geïnterpreteer dat dit kwesbare huurders tydens uitsettingsprosedures met substantiewe okkupasieregte beskerm. Om aan artikel 25(6) te voldoen moet wetgewing egter substantiewe okkupasieregte met verblyfsekerheid aan residensiële huurders verskaf voordat hulle uitgesit word. Die wetgewer het die Wet op Huurbehuising en die Wet op Maatskaplike Behuising verorden ten einde effek aan die reg op behuising (artikel 26 van die Grondwet) in die gebied van huurbehuising te gee. Geeneen van hierdie wette slaag daarin om toegang tot behuising, en veral huurbehuising as 'n vorm van okkupasie, te bevorder ten einde die behuisingtekort te verminder nie.

Resumen
Thesis (LLM)--Stellenbosch University, 2012.
ENGLISH ABSTRACT: Section 25(6) of the Constitution of the Republic of South Africa 1996 guarantees legally secure tenure to persons whose tenure of land is insecure as a result of past racially discriminatory laws and practices. The Extension of Security of Tenure Act 62 of 1997 (ESTA) and the Land Reform (Labour Tenants) Act 3 of 1996 (LTA) were enacted to give effect to section 25(6), read with section 25(9) of the Constitution, with the aim to improve and strengthen tenure security in rural areas, including farmland. However, the general opinion amongst scholars is that these efforts to strengthen tenure security have generally failed to ensure legally secure tenure on farmland. To this effect, the Draft tenure security policy and Draft Land Tenure Security Bill (2010) were formulated to introduce new measures to improve tenure security on farmland. This gives a clear indication that eighteen years after the government embarked on an all-encompassing land reform programme, its intended goals have not yet been achieved, resulting in the continued challenges faced by farm dwellers. The thesis discusses the inherent challenges associated with tenure security on white-owned commercial farmland, with specific reference to government‟s obligation to improve tenure security; the nature of farm dwellers‟ rights; and the shortcomings of the existing policy and legislative measures. A historical overview explains the effects of the apartheid land holding system that underpins the need for tenure reform, while an analysis of constitutional and international law sets out the guiding principles on tenure security. An analysis of the applicable policy and legislative measures establishes the causes of continued tenure insecurity on farmland, which include shortcomings in the main legislative measures; failure by the legislature to translate policy into legislation; misinterpretation and misapplication of legislation by the courts; and lack of effective implementation. The thesis considers the impact of the Draft tenure security policy and the Bill in light of the challenges facing farm dwellers and concludes that tenure security in relation to farmland remains insecure and government still falls short of the appropriate solutions to address the tenure security challenges on farmland.
AFRIKAANSE OPSOMMING: Artikel 25(6) van die Grondwet van die Republiek van Suid-Afrika 1996 waarborg sekerheid van verblyfregte vir persone wie se verblyfregte regsonseker is as gevolg van ras-diskriminerende wette en praktyke van die verlede. Die Wet op die Uitbreiding van Sekerheid van Verblyfreg 62 van 1997 (ESTA) en die Wet op Grondhervorming (Huurarbeiders) 3 van 1996 (LTA) is gepromulgeer om gevolg te gee aan artikel 25(6), saamgelees met artikel 25(9), van die Grondwet, wat daarop gemik is om die sekerheid van verblyfregte in landelike gebiede te verbeter en te versterk. Die algemene siening onder geleerdes is egter dat hierdie pogings om sekerheid van bestaande verblyfregte te versterk oor die algemeen ten opsigte van verblyfregte op landbougrond gefaal het. In verband hiermee is die Konsep beleid op sekerheid van verblyfregte (Draft tenure security policy) en die Konsep Wetsontwerp op die Sekerheid van Verblyfregte in Grond (Draft Land Tenure Security Bill) (2010) geformuleer om nuwe maatreëls voor te stel om sekerheid van verblyfregte ten opsigte van landbougrond te bewerkstellig. Hierdie ontwikkelings gee ‟n aanduiding dat die staat ná ‟n omvattende grondhervormingsprogram van agtien jaar nie die beoogde doelwitte bereik het nie en dat plaasbewoners steeds uitdagings in die gesig staar. Hierdie tesis bespreek die inherente uitdagings wat geassosioseer word met regsonsekere verblyfregte ten opsigte van kommersiële landbougrond, hoofsaaklik van wit grondeienaars, met spesifieke verwysing na die staat se plig om regsekerheid te versterk; die aard van plaasbewoners se regte; en die tekortkominge van die bestaande beleids- en wetgewende maatreëls. Die behoefte aan hervorming word beklemtoon met verwysing na ‟n historiese oorsig wat die uitwerking van die apartheid-grondbeheerstelsel verduidelik, terwyl ‟n analise van grondwetlike en internasionale reg die beginsels met betrekking tot die sekerheid van verblyfregte uiteensit. ‟n Analise van die toepaslike beleids- en wetgewende maatreëls dui op die oorsake van voortdurende onsekerheid van verblyfregte in landbougrond, wat die volgende insluit: tekortkominge in die primêre wetgewende maatreëls; versuim deur die wetgewer om beleid in wetgewing om te skakel; foutiewe uitleg of toepassing van wetgewing deur die howe; en ‟n gebrek aan die effektiewe uitvoering van wetgewing. Die tesis oorweeg die impak van die Konsep beleid op sekerheid van verblyfregte (Draft tenure security policy) en die Konsep Wetsontwerp in die lig van die uitdagings waarmee plaasbewoners steeds te kampe het, en kom tot die gevolgtrekking dat verblyfregte ten opsigte van landbougrond steeds regsonseker is en dat die staat steeds versuim om geskikte oplossings vir die uitdagings daar te stel.

Resumen
The dwindling supply of castrati created a crisis in the opera world in the early 19th century. Castrati had dominated opera seria throughout the 18th century, but by the early 1800s their numbers were in decline. Impresarios and composers explored two voice types as substitutes for the castrato in male leading roles in serious operas: the contralto and the tenor. The study includes data from 242 serious operas that premiered in Italy between 1800 and 1840, noting the casting of the male leading role for each opera. At least 67 roles were created for contraltos as male heroes between 1800 and 1834. More roles were created for tenors in that period (at least 105), but until 1825 there is no clear preference for tenors over contraltos except in Naples. The Neapolitan preference for tenors is most likely due to the influence of Bourbon Kings who sought to bring Enlightenment values to Naples. After the last castrato retired in 1830 and the casting of contraltos as male heroic leads falls out of favor by the mid-1830s, the tenor, aided by a new chest-voice dominant style of singing, becomes the inheritor of the castrato's former role as leading man in serious Italian opera.

Resumen
Urbanisation in sub-Saharan Africa is characterised by a proliferation of informal settlements which all too often embody poverty; low access to basic services and lack secure tenure. The reality of sanitation infrastructure in low and middle income cities is a spectrum of sanitation systems ranging from conventional utility managed systems to basic household facilities. Population growth has outpaced urban planning and provision and, given projected urbanisation trends, a prevalence of non-piped self-build sanitation systems is the most likely scenario for urban sanitation in the developing world, at least for the immediate to mid-term. This presents different governance challenges especially as informal occupations are often on unsuitable land which exacerbates the difficulties in service provision. Sanitation, tenure and development are inextricably linked, not only with respect to these challenges of urbanisation, but also under the strategic objectives of the Millennium Development Goals (MDG). Together sanitation and tenure security are primary indicators of the MDG7, targets ten (access to improved sanitation) and eleven (improving the lives of slum dwellers). The link between sanitation and tenure is the focus of this research. Both tenure and sanitation are fragmented into their component parts to understand exactly how and where they interact. Tenure is defined in terms of formal land tenure; tenure status (to differentiate between landlord and tenant) and tenure security. Sanitation issues are investigated with respect to access, household investment and emptying behaviours. The research framework combines the concept of decision making domains to describe the urban context with a city-wide systems view of sanitation, where both formal and informal institutional arrangements are considered. This research concludes on five main points: firstly, tenure security is a necessary precondition for household investment but, given that urban sanitation development and provision happen largely under the radar of formal city planning and urban management, it is de facto rather than de jure tenure rights that provide the security for household investment in sanitation. The second finding is that few urban sanitation strategies cater for those who are unwilling or unable to invest. This is a fundamental oversight in current urban sanitation strategies of the population segments who cannot invest, thus failing to provide a sanitation strategy for all. This is of growing concern given the type of urbanisation being witnessed in developing countries characterised by increasing concentrations low income populations and tenants. The third finding is that those who are unwilling to invest may be willing to pay (and do) for sanitation services. This places a greater emphasis on downstream and operational sanitation activities (i.e. tenure neutral options). The fourth finding is that there are multiple service providers and majority of urban sanitation transactions take place outside the formal service provision. Giving meaning to these informal transactions is likely to offer insight into improved governance for urban sanitation. The final point is that there is a need to widen the scope of formal sanitation service provision to include tenure neutral sanitation options to reach the needs of tenants and those living with poor tenure security. xiii Practically, this means that by taking a city-wide approach supported by the sanitation cityscape tool which is presented in the thesis one can identify which element(s) of the sanitation system are most appropriate to target given the tenure situation. Without this consideration, urban sanitation interventions are likely to be targeted inappropriately. These conclusions are based upon primary data collected from a household survey (n=363) and a series of key informant interviews collected during 2008 in Greater Dakar, Senegal.

Resumen
With the shifts in housing tenure patterns in post-war Britain being so decisive and apparently relentless, one of the main issues that concerns those involved with housing is that of the impact of mass home-ownership - especially on those groups new to the tenure. These concerns range from the possible effect of new home-owner ship on voting patterns and political allegiances; to the financial hardship that seems to be increasingly falling on low income owner occupiers; and to the domestic and familial changes entailed by two-income mortgages. It is towards assessing the impact of these changes more fully, that this thesis is aimed. In order to better understand the origins and effects of tenure shifts, two main points are made. Firstly, that the occupation of houses (of whatever tenure) is an issue that involves practically everyone in society, either as individual tenants/owners/homeless persons, or as groups of ratepayers/voters/neighbourhoods or as business/financial/political interests, or as any combination of these. Secondly, it is emphasised that the terms and conditions of the various tenures have been created and have been altered and adapted over time, and that the definition and meaning of the tenures is as crucial to the housing debate as the well-recognised tenure trends. Consequently, it is argued that the changing patterns and definitions of tenures have a crucial and far-reaching effect on wider social relations in society whilst, at the same time, these changes originate from and in part reflect, already occurring events in civil society.

Resumen

In the state of Missouri, 550 public school superintendents were selected to have their district teachers participate in a study to provide information regarding the perception of teacher tenure. Approximately 64,000 PreK-12 public school teachers in Missouri were sent an 18 question online survey designed by the researcher to assess Missouri public school teachers’ perception of teacher tenure. A sample of 497 Missouri teachers participated in this study. Sub-questions of the purpose of the research study were adapted from Kersten (2006): (1) When teachers achieve tenure, are they more effective and highly qualified? (2) If teacher tenure was eliminated, would student achievement increase? (3) Does the teacher tenure law in Missouri protect good teachers from arbitrary dismissal? and (4) Do teachers have knowledge of the proposed revised tenure law in Missouri? The respondents were prompted to identify gender, years in current position, education level, description of grade levels in school building, and school district’s region. The research study findings produced several conclusions which included the following: (1) Teacher tenure in Missouri does not determine if teachers are effective and highly qualified; (2) Abolishing tenure or changing the current tenure law will not improve student achievement; (3) Tenure is perceived to protect competent teachers from arbitrary dismissal; however, incompetent or ineffective teachers are seldom dismissed; and (4) Many teachers have knowledge of the proposed revised teacher tenure law in Missouri, and they learned of the upcoming legislation from professional teaching organizations.

Resumen
Studien motiveras av införandet av obligatorisk byrårotation i Sverige genom EU:s revisionspaket. Studien undersöker sambandet mellan audit-firm tenure (längden på en revisionsbyrås uppdrag hos ett företag) och revisionskvalitet. Som proxy för revisionskvalitet används mått på absoluta diskreta periodiseringar. För att genomföra studien görs en regressionsanalys och ett korrelationstest. Urvalet baseras på svenska företag noterade på Nasdaq Stockholm Large- och Mid Cap och det slutliga antalet företagsår som studeras är 383 stycken. I kontrast till stor del av tidigare studier finner denna studie att revisionskvaliteten är högre vid kort audit-firm tenure, tre år eller kortare, jämfört med lång audit-firm tenure, fyra år eller längre. Resultatet kan säkerställas på en signifikansnivå på 10 %. Studien bidrar med underlag till debatten om obligatorisk byrårotation.

Resumen
Zambia has since independence experienced a decline in per-capita food production. Among the assumed causes of this decline are land tenure relations. This thesis has discussed the relationship between land tenure systems and agricultural development. It has considered the effects of this relationship on productivity, investment and employment generation. It demonstrates that the prevalence of traditional land tenure systems in the rural areas is inconsistent with the rule structures of modern institutions providing credit, marketing, input supply and extension. The thesis however, recognizes that a reform of these land tenure institutions is not a panacea to agricultural productivity unless accompanied by the provision of agricultural services. The thesis is divided into two parts. The first part sets out the philosophy of the research, the theoretical framework and provides background and illustrative information on the relationship between land tenure reform and agricultural development in sub-Saharan Africa. This part also sets out the historical, economic and political context to land tenure reform in Zambia both in the colonial and post-colonial periods. The second part discusses the case study of Petauke District. In this exposition, the effects of tenure on agricultural productivity, investment and employment creation are examined by analyzing primary data concerning access to credit, marketing, input supply and extension services. In organising chapters 4 to 8 concerning sub-Saharan Africa, Zambia and the case study of Petauke district, the thesis utilized the structure and agency philosophical framework. The explanation of the relationship between land tenure and agricultural development however, employed institutional models developed by both economists and planners.

The current state of the art for transposing sparse tensors involves converting the sparse tensor into a list of coordinates, sorting the list of coordinates and finally packing the list of coordinates into the desired sparse tensor format. This thesis explores the potential for faster methodologies. Its main contributions are an algorithm that exploits partial sortedness to minimize sorting passes and an implementation that demonstrates that this transposition algorithm is competitive with state of the art. In particular the algorithm takes advantage of the ordering that already exists to apply selective sorting passes and thereby reduce the amount of work that needs to be done to reorder the tensor.

Resumen
Our subject area of research is Mathematical Finance. In this thesis, we price a novel form of barrier structure which is closely related to a swaption having a continuous time log-normal model, which is the underlying dynamic of the asset, a forward par swap rate. The new feature is where the barrier is monitored before and during the swap period. It is called ”Tenor Varying Barrier Swaption”. It means that even though the exercise date of the swaption is fixed at time t0, the length of the swap may vary according to when the barrier is breached. The pay-off function of the barrier structure is the summation of pay-offs of all possible situations that swap contract can last. In pricing a standard barrier option, the essential part is to calculate the joint probability distribution of Brownian Motion and its running maximum at the fixed time point. However, in our case, the running maximum is measured at the later time beyond the point which we measure Brownian Motion. The novelty in the Mathematics is then in obtaining the probability distribution of Brownian Motion and its running maximum at random distinct time points. The price of Tenor Varying Barrier Swaption is finally obtained via the aid of numerical integration. In addition to that, practically, in the financial market, most barrier structures are monitored discretely. The problem arises when we have to price a discretely monitored barrier swap having a continuous time model as an underlying model of the swap rate dynamic. By modifying the approximation method of Broadie, Glassermann and Kou, we can price of the discretely monitored tenor varying barrier structure successfully. This gives an approximated solution to a new type of interest rate security, which can protect both an investor’s and a writer’s benefits.

Resumen
This thesis presents extended program notes for a seventy-minute vocal graduate recital consisting of the following repertoire for tenor: Johann Sebastian Bach’s cantata Ich armer Mensch ich Sündenknecht; two songs from the eighteenth-century Spanish collection Tonadillas Escénicas; Gaetano Donizetti's song La derniére nuit d'un novice; Francis Poulenc's song cycle Tel jour telle nuit; Jake Heggie's song cycle Friendly Persuasions; and John Corigliano's Three Irish Folk Songs for Flute and Tenor. Spanning four centuries of music and representing four different language traditions, these works are sufficiently representative of the tenor repertoire. The content of this thesis features detailed information on these works through historical study, and musical analysis.
