Identifying the resources that limit bee populations is essential both for bee conservation and pollination management in agroecosystems. Land-use change typically leads to decreased habitat availability for wild pollinators including loss of nesting habitat, which is an essential but often-overlooked resource for wild bees. Cavity-nesting bees, such as many Osmia spp. (Hymenoptera: Megachilidae), occupy holes in wood or reeds to build their nests; due to their nesting habits, they are frequently scarce in agricultural settings, although, under the right circumstances, these bees can be ideal pollinators of apple and other orchard crops. Artificial nesting structures (“bee hotels”, “trap nests”, or “nest boxes”) are used to study cavity-nesting bees and have been posited as solutions for promoting bee conservation. To evaluate the effects of additional nesting habitat on the local abundance of Osmia spp., and on bees more generally, artificial nesting structures for cavity-nesting bees were installed at 24 sites in apple orchards around Ottawa in 2021 and 2022. Each site had two treatments: one with nest boxes, and one without (control). Transect walks were conducted to measure overall bee contact (including contact by Osmia spp.) with apple blossoms and, after the end of apple bloom, with flowers in the undergrowth and/or in shrubs. Numbers of apple buds and developing fruit were also recorded. Osmia spp. and overall bee numbers were both significantly higher in the treatment with nest boxes (44% and 15% higher, respectively, in 2021, and 113% and 47% higher, respectively, in 2022); however, there was no difference in fruit set (apple count/bud count) between the two treatments. Thus, nest boxes seem to locally increase Osmia spp. numbers as well as total bee numbers, but they have no apparent effect on apple yield, likely because apple production was not pollinator limited in the years of this study. These findings suggest that bee populations in apple orchards are limited by nesting resources, which has important implications for orchard management practices and bee conservation policy.

La présente recherche porte sur la traduction de la bande dessinée. Ce sujet, auparavant négligé par les traductologes, commence à susciter l’intérêt des chercheurs à partir les années 80. Toutefois, la plupart des travaux se sont concentrés sur l’aspect linguistique des BD. Ce mémoire, par contre, aborde la bande dessinée comme un texte multimodal. Il s’inscrit ainsi à la croisée des domaines de la traduction et de la multimodalité telle que proposée dans les travaux de Gunther Kress et Theo Van Leeuwen (2001). L’objectif de cette recherche est d’implanter un outil d’analyse pour la bande dessinée qui permettrait de rendre compte des différents modes intervenant dans le texte. Cet outil, conçu pour la présente recherche, a été développé à partir des travaux de Hatim et Mason (1990, 1997) sur les trois dimensions de la situation de communication : transaction communicative, action pragmatique et interaction sémiotique. L’analyse menée ici porte sur la traduction vers le français de la bande dessinée argentine Mujeres alteradas de Maitena Burundarena, parue sous le titre de Les déjantées. / The present research deals with the translation of comics. This topic, long time neglected by translation scholars, has started to attract researchers from the 80s. The research on the subject, however, has focused mainly in the linguistic aspect of comics. This paper, on the other hand, deals with comics as multimodal texts. It is thus at the cross-roads of both Translation Studies and Multimodality as defined by Gunther Kress and Theo Van Leeuwen (2001). The aim of this research is to apply a tool which allows to describe the different modes contained in the text. This tool, created for this research, is based on Hatim and Mason’s (1990, 1997) Three Dimensions of Context : Communicative Transaction, Pragmatic Action and Semiotic Interaction. This paper studies the French translation of Mujeres alteradas, an Argentinian comics created by Maitena Burundarena and published in France as Les déjantées.

Richard Mason proposed a social framework for addressing the major ethical issues of the information age in his pivotal 1986 article “Four Ethical Issues of the Information Age.” In 2006, Alan Peslak validated the framework by measuring the current attitudes of students, IT professionals, and university faculty and staff toward the four key issues proposed by Mason: privacy, accuracy, property, and accessibility (referred to as PAPA). This study continues this inquiry into the seven-year period after Peslak’s research. Previously collected data was analyzed for 312 university computing majors taking a senior-level ethics course where Mason was taught and discussed. Demographic influences as well as differences over the period were considered. A single exam question administered consistently over the period was the focus. Results indicate, with Mason’s framework as a foundation, computing students can identify all of Mason’s ethical issues, selecting privacy as the most relevant issue of concern in their current environment. Age, gender, and computing work experience resulted in no differences in selection of relevant PAPA factors. All genders, all age groups, and all levels of computing work experience select privacy as the most relevant factor for society today. Privacy increased in importance over the seven-year period as the primary ethical issue for computing students. The ever-changing technology environment and new threats to society posed by these changes is discussed, including social networks, data breaches, consumer privacy, internet neutrality, and emerging technologies.

This thesis is a study of the Community Relations Department of the Southern Organizing Committee of the Congress of Industrial Organizations during the CIO’s Southern Organizing Drive, often referred to as “Operation Dixie.” The Community Relations Department was primarily interested in improving relations between organized labor and organized religion, in the hopes that improved church-labor relations would produce a situation more conducive to labor organizing, and reduce attacks on the CIO from religious leaders. This thesis examines the methods utilized by the CRD to achieve this end, and presents an analysis both of their efficacy and of their implementation. Specific programs that are explored are the CRD’s compilation, and publication, of various religiously themed pamphlets, the formation of Religion and Labor Fellowship groups, and the CRD’s relations with various anti-labor newspapers that made use of religious arguments to attack the CIO and Operation Dixie.

Repeated cold exposures and warmer winter temperatures might negatively affect insects by depleting stored fuel reserves. I researched the effects of fluctuating thermal regimes on two species of solitary mason bees (Osmia albiventris and O. lignaria) by quantifying mass loss and reserves of lipids, free sugars, and glycogen after experimental temperature treatments during early spring. In a second season, I quantified mass loss, time to emergence, and time to recover from chill coma after bees had been exposed to one of two spring-time temperature regimes. I found that warmer temperatures in combination with greater temperature variability increases mass loss and the depletion of fuel reserves. Additionally, my results suggest that accelerated bee emergence helps to mitigate mass loss. Overall, these bees appear resilient in the face of changing spring temperatures. Résumé: On sait peu sur la façon dont la variabilité environnementale affecte les abeilles solitaires sauvages. Ma recherche a étudié la façon dont les régimes thermiques fluctuants affectent la vigueur de deux espèces d'abeilles solitaires (Osmia albiventris et O. lignaria) en quantifiant la perte de masse ainsi que les réserves métaboliques (lipides, sucres libres, et glycogène) des abeilles suite à des manipulations expérimentales de la température printanière. Dans une deuxième saison, j’ai quantifié la perte de masse, le temps de l'émergence et le temps pour récupérer du coma froid après que les abeilles avaient été exposées à l'un de deux régimes de températures printanières. Mes résultats indiquent que les températures plus chaudes ont tendance à augmenter la perte de masse et des réserves métaboliques lorsqu'elles sont combinées avec une plus grande variabilité. De plus, mes résultats suggèrent que ces abeilles sont résilientes face aux températures printanières changeantes.

This dissertation argues that the four writers named above use the grotesque to illustrate the increasingly peculiar consequences of the assault of modernity on traditional Southern culture. The basic conflict between the views of Bakhtin and Kayser provides the foundation for defining the grotesque herein, and Geoffrey Harpham's concept of "margins" helps to define interior and exterior areas for the discussion. Chapter 1 lays a foundation for why the South is different from other regions of America, emphasizing the influences of Anglo-Saxon culture and traditions brought to these shores by the English gentlemen who settled the earliest tidewater colonies as well as the later influx of Scots-Irish immigrants (the Celtic-Southern thesis) who settled the Piedmont and mountain regions. This chapter also notes that part of the South's peculiarity derives from the cultural conflicts inherent between these two groups. Chapters 2 through 5 analyze selected short fiction from each of these respective authors and offer readings that explain how the grotesque relates to the drastic social changes taking place over the half-century represented by these authors. Chapter 6 offers an evaluation of how and why such traditions might be preserved. The overall argument suggests that traditional Southern culture grows out of four foundations, i. e., devotion to one's community, devotion to one's family, devotion to God, and love of place. As increasing modernization and homogenization impact the South, these cultural foundations have been systematically replaced by unsatisfactory or confusing substitutes, thereby generating something arguably grotesque. Through this exchange, the grotesque has moved from the observably physical, as shown in the earlier works discussed, to something internalized that is ultimately depicted through a kind of intellectual if not physical stasis, as shown through the later works.

The main objective of the research and its writing is an attempt to prove a historiographical connection as well as of themes and of style among these three novels, in their effort to reinterpret the American History in a strongly ironic way. This has been characterized by Harold Bloom (also in a ironical way, it seems) as “the style of our age”, among other reasons because the three writers as well as their three novels are focused on grasping different periods of the United States History and on deconstructing the main basis of American myths, even if through different and individualized narrative styles. The most important of these myths is the one that, since the Colonial Period, and based in the belief that being White, Protestant and of Anglo-Saxon origin would make the new man to be born in the New Continent a New Adam, and his nation, America, a new and exemplar Paradise on Earth. Mason & Dixon, Blood Meridian and American Pastoral show, each one in his own way, how this myth resulted in failure. In order to achieve this we have chosen three main myths as the basis for this research: The Myth of the American Eden (from the European imaginary Colonial Paradise); The Myth of the American Adam (from the concept of the new man, inhabitant of that Paradise; The Myth of the Manifest Destiny (the Messianic idea of a possible Universal Paradise). In order to achieve this, in the first chapter, dealing with Mason & Dixon, we will analyze the context of the Eighteenth Century and the beginning of the American Nation. In the second chapter, dealing with Blood Meridian, we will analyze the context of the Nineteenth Century, when the territorial expansion during the Great March to the West took place. In third and last chapter, dealing with American Pastoral, the context of the Twentieth Century, specifically the period from the end of World War II to the 1990s, that is, from the American Golden Age of prosperity to the economic and social crisis during and after the Vietnam War. Finally, we will try to analyze the logic of the irony shared by the three authors who, in their three novels, historically summarize the failure of the formation of the ideal nation based on its three main myths and its continual recurrence to different types of violence / Esta tese é uma leitura comparativa de três autores contemporâneos de destaque na ficção norte-americana: Thomas Pynchon, Cormac McCarthy e Philip Roth, a partir de três romances escritos por eles: Mason & Dixon; Blood Meridian e American Pastoral, respectivamente, nesta ordem aqui analisados. O objetivo principal da pesquisa e escrita da tese é uma tentativa de comprovar uma relação historiográfica mas também de temas e de estilo entre as três obras citadas, ao se empenharem em reinterpretar a História ame-ricana de modo fortemente irônico, que Harold Bloom (também ironicamente, parece) denominou como um exemplo do que seria the style of our age – o estilo de nossa época –, entre outras razões, por serem tanto os três escritores como seus três romances empe-nhados em abordar diferentes períodos da História dos Estados Unidos e a desconstruir as principais bases dos mitos americanos, mesmo se através de estilos narrativos indivi-duais díspares, principalmente aquele através do qual, desde a colonização e com base na crença de que ser branco, protestante e de origem anglo-saxônica tornaria o novo homem a nascer no novo continente, um novo Adão, e sua pátria, a América, um novo e exemplar Paraíso. Mason & Dixon, Blood Meridian e American Pastoral mostram, cada um a seu modo, como esse mito resultou em fracasso. Para tanto, baseamos nossa pesquisa em três mitos principais: 1. Mito do Éden americano (originado do imaginário europeu sobre o Paraíso colonial); 2. Mito do Adão americano (o conceito do homem novo, habitante do Paraíso); 3. Mito do Manifest Destiny (a ideia messiânica para um Paraíso universal). Para conseguir isso, no primeiro capítulo, abordaremos, em Mason & Dixon, o contexto do século XVIII e formação da nação americana; no segundo capítulo, em Blood Meridian, o contexto do século XIX, durante o qual a expansão do território americano durante a Campanha para o Oeste aconteceu; no terceiro e último capítulo, em American Pastoral, o contexto do século XX, especificamente do fim da Segunda Guerra Mundial até a década de 90, isto é, da era de ouro do desenvolvimento dos EUA até as crises políticas e econômicas durante e depois da Guerra do Vietnã. Por fim, pretendemos analisar a lógica da ironia comum aos três autores que, em seus três livros, historicamente resumem o fracasso da formação da nação ideal fundamentada em seus três mitos principais e por sua contínua recorrência a diferentes tipos de violência.

Virtually any construction project in our climate zone is facing some form of moisture. Older and historical buildings are mostly affected by the negative impact of water. Previously, the additional reduction of the moisture was executed only by mechanical methods, pushing insulating sheets or breaking through and cutting of masonry. Over time chemical methods were also invented, which are compared to the mechanical considerably simpler and user friendly applications to statics of treated buildings, making them ideal for the treatment of historical buildings or buildings that would not bear significant disruption. The main principle of chemical methods of redevelopment of wet masonry is the application of special material into the line of drilled holes with a given pitch. Subsequent penetration of the grouting material is believed to intersect an arc of individual drill holes, and thus to create so-called grout curtain that prevents the accumulation of water above it. Injection material may also contain a proportion of secondary raw materials, thereby reducing the influence of the impact of production on the environment. Efficiency infusion materials in masonry affected by many factors, such as temperature, humidity, or the type of material treated. It is also an important factor to determine the effectiveness of the remediation of the material, proving its ability to penetrate the building material by identifying its presence in it.

Increased moisture of masonry occurs mainly in older buildings. In some cases these problems arise even in new buildings. This issue should be properly treated and process of rehabilitation of the building must be executed. Humid walls can be treated by chemical injections, which is nowadays quite extensive and widely used method. Unlike mechanical methods humid walls in the implementation of chemical grouting does not need a major redesign and thus is friendly to the construction of the object. The main objective of this thesis is to establish a methodology for testing the injection materials, which will include a selection of ideal injection gel.

This thesis explores the implications of chinoiserie, or Western creations of Chinese-style decorative arts, upon an eighteenth century colonial American audience. Chinese products such as tea, porcelain, and silk, and goods such as furniture and wallpaper displaying Chinese motifs of distant exotic lands, had become popular commodities in Europe by the eighteenth century. The American colonists, who were primarily culturally British, thus developed a taste for chinoiserie fashions and wares via their European heritage. While most European countries had direct access to the China trade, colonial Americans were banned from any direct contact with the Orient by the British East India Company. They were relegated to creating their own versions of these popular designs and products based on their own interpretations of British imports. Americans also created a mental construct of China from philosophical writings of their European contemporaries, such as Voltaire, who often envisioned China as a philosopher's paradise. Some colonial Americans, such as Benjamin Franklin and Thomas Jefferson, fit their understanding of China within their own Enlightenment worldview. For these individuals, chinoiserie in American homes not only reflected the owners' desires to keep up with European fashions, but also carried associations with Enlightenment thought. The latter half of the eighteenth century was a time of escalating conflict as Americans colonists began to assert the right to govern themselves. Part of their struggle for freedom from England was a desire to rid themselves of the British imports, such as tea, silk, and porcelain, on which they had become so dependent by making those goods themselves. Americans in the eighteenth century had many of the natural resources to create such products, but often lacked the skill or equipment for turning their raw materials into finished goods. This thesis examines the colonists' attempts to create their own chinoiserie products, despite these odds, in light of revolutionary sentiments of the day. Chinoiserie in colonial America meshed with neoclassical décor, thereby reflecting the Enlightenment and revolutionary spirit of the time, and revealing a complex colonial worldview filled with trans-oceanic dialogues and cross-cultural currents.
