Invasive species often threaten biodiversity and environmental processes in their introduced range by extirpating native species due to competition for resources. Nylanderia fulva (formerly N. (=Paratrechina) sp. nr. pubens) is an ecologically dominant and economically important invasive species in the United States. This dissertation addresses aspects of the biology, behavior, management, and collection techniques for N. fulva. Specifically, topics investigated include a modified drip technique for extracting ants from their substrate, the effectiveness of a broadcast ant bait as a stand-alone treatment, the foraging preference and peak activity of workers, the reproductive potential of queens, and the ability of this species to translocate pathogenic microorganisms. The primary goal of these works was to better understand the biological idiosyncrasies of this species that may ultimately lead to the mitigation N. fulva populations. A modified drip technique was developed to quickly and efficiently extract N. fulva from their nesting substrates. Ants and their associated substrates were collected in 18.9 L buckets lined with talcum powder and transported to the laboratory. Substrates were weighted down and a cardboard tower was provided for the immigration of ants as they were forced out of substrates with a slow influx of water. Three applications of Advance Carpenter Ant Bait (ACAB) were applied to a N. fulva population in East Columbia, TX. A series of GIS interpolated maps depict achieved management and subsequent rebound of N. fulva populations. As great as 77% population reduction was achieved by 1 week post treatment, but N. fulva populations rebounded within 3-4 weeks. As a stand-alone treatment, this bait did not provide adequate ant management in treatment plots. Diet preference experiments were performed using artificial diets and food lures. These results of these trials indicated that N. fulva preferred the most carbohydrate rich diet offered through all seasons and that mint apple jelly or hot dog slices were the favored food lures. Diel foraging behavior was observed when temperatures were between 9.95 and 37.26 degrees C. Peak foraging activity occurred at 28.24 +/- 3.12 degrees C. A laboratory investigation of N. fulva suggested that as the number of queens increased, individual queen fecundity increased. This phenomenon is a novel observation among ants and suggests an alternative mechanism for intracolony dominance. Hexagyne colony fecundity of 0.25 +/- 0.12 eggs/queen/hr was the maximum fecundity observed. Results of laboratory experiments showed that N. fulva were capable of transferring E. coli up to 4.5 m in 6 hrs after acquisition from a contaminated source. Pyrosequencing of ectomicrobial assemblages revealed a suite of 518 bacteria and 135 fungi species associated with N. fulva, many of which are known pathogens of plants and animals, including humans. These results suggested that N. fulva should be regarded as both a medically and agriculturally important species.

The notion of the 'public intellectual' has been a recurring discussion topic within sociology and the humanities for decades. Yet it has been largely neglected within media and cultural studies. Accordingly, few scholars have discussed in much depth how public intellectuals operate within the media and what functions this media role may facilitate. Intellectuals in the Australian Press is an exploration into this generally overlooked area of scholarship. It aims to provide three levels of insight into the topic. Firstly, the study looks closely at the appearance and the function of public intellectuals in the Australian press. It outlines how public intellectuals contribute to the newspapers and how newspapers contribute to Australian public intellectual life. Secondly, the thesis outlines and examines in detail three types of public intellectual in Australia. Specifically, it examines the journalist, the academic and the think tank researcher as types of intellectual who write regularly for Australia's newspapers. Thirdly, Intellectuals in the Australian Press delivers detailed intellectual biographies of three of Australia's most prominent press intellectuals, each of whom exemplifies one of these three categories. These commentators are The Australian's Paul Kelly, The Age's Robert Manne, and the Sydney Morning Herald's Gerard Henderson.

Any society is by nature coercive and its institutions are no exception. This was true of mission institutions in South Africa. While acknowledging the invaluable contribution of mission education to the development of black South Africans predominantly, it is clear that Lovedale Missionary Institution exemplifies the concept and reality of a ‘total institution’ which was as susceptible to the problems of power relations as any institution, secular or religious. Idris Shah’s concept of ‘coercive agency’ is apposite for this study. Lovedale’s foundation was laid and developed by the first two Principals. In a very real sense, it was perfected by the third Principal of Lovedale, James Henderson who, like his predecessors, emphasised the ultimate aim of conversion through a thorough process of character formation which infiltrated every aspect of life at Lovedale, especially discipline and the programme of industrial education. Those who studied there internalised its ethos in a manner which could not simply be discarded on leaving the Institution for it had become part of their identity, their indigenous personality and traditional life-style having been largely obliterated and reconstructed according to the ideological ideals of western Christian civilisation and European colonialism. Coercive agency was successful in that it effectively encouraged adaptation to missionary ideology. However, this was not an irreversible process for many Lovedale students came to reject the mores of the religion and education they received both during their stay at Lovedale and in later life in a variety of ways as they challenged and resisted the effects of the coercive agency of internalisation. Institutionalisation is, by nature, resistant to change as can be seen in the policies of the respective Principals. Yet, Henderson was able to initiate change while maintaining essential continuity of purpose. Consequently, black people were alienated by a process of ‘exclusion’. The Christian principles of justice, love and peace have a universal application and are appropriate tools for the development of a new model of education in South African society whose mission is to work towards reconciliation between individuals, within society and with the God who wishes to ‘embrace’ the totality of creation. / Christian Spirituality, Church History and Missiology / D.

Este fue el caso de las tecnologías edilicias y los pioneros que se arriesgaron a utilizarlas en la región rodeada del Mar Caribe y el Océano Atlántico. Estas obras fueron importantes exponentes de una evolución y revolución tecnológica, desde 1895-1930, enmarcados por la Revolución Industrial y las guerras que definieron el período.

U.U. en Cuba, proveyó un activo amanecer a la industrialización en la región y la inmigración de profesionales de la industria de la construcción. En las islas progresistas del Caribe Hispano, el furor por la "modernización" aumentó debido a los logros estructurales exitosos en los E.E. U.U. para esta época, donde edificios en ciudades como Chicago y Nueva York habían alcanzado nuevas alturas y estructuras mucho más ligeras construidas con esqueletos fabricados de acero. Durante este período de experimentación y riesgo descontrolado, el uso de elementos importados para edificar una estructura de acero sirvió como sustituto viable a la construcción tradicional. Esto ayudó a que se convirtiese en la tecnología preferida para la construcción de estructuras altas, ligeras, con menos divisiones interiores, grandes ventanales y a prueba de fuego y de huracanes. Como resultado de estas iniciativas, entre los años 1899-1900, se estableció en La Habana la primera sucursal ultramar de los ingenieros estadounidenses Purdy & Henderson. Los esfuerzos y visión de esta empresa exitosa de diseño, compuesta por ingenieros y arquitectos talentosos y experimentados, los trajeron a Cuba, donde podrían establecerse con sus conocimientos vanguardistas y experiencia innovadora. Poco se ha escrito sobre la importante obra habanera de P&H, y esta tesis llena este vacío. Los primeros proyectos cubanos de esta compañía, que coincidieron con los años fundacionales de la República de Cuba, incluyeron múltiples edificios con estructura de acero revestidos con distintos materiales arquitectónicos. Entre estas estructuras emblemáticas se encuentran el Centro Gallego, el Capitolio, y el Hotel Nacional. Sus labores incluyeron una estrecha colaboración con arquitectos e ingenieros cubanos, sirviendoles como sus consultores. A la vez, P&H incorporó servicios de construcción y supervisión de obras a esta sucursal de su empresa, e incluyó también la importación de materiales y equipos para proyectos. Sus contribuciones en Cuba (y específicamente en La Habana), como poder importante en la región, merecen el enfoque de esta tesis doctoral. / [CA] Les ciutats portuàries es beneficien de dissenys innovadors a un ritme més ràpid que els assentaments de l'interior, servint com a camps de prova i laboratoris tècnic-edilicis.

La feina de casa van incloure una estreta col·laboració amb arquitectes i enginyers cubans, sirviéndoles com els seus consultors. Alhora, P&H va incorporar serveis de construcció i supervisió d'obres a aquesta sucursal de la seva empresa, i va incloure també la importació de materials i equips per a projectes.

This was the case of the building technologies and pioneers who risked using them in the region surrounded by the Caribbean Sea and the Atlantic Ocean. These projects were important exponents of a technological evolution and revolution, from 1895-1930, framed by the Industrial Revolution and the wars that defined the period. Early 20th century construction technologies using Portland cement have been under studied in the tropics. Achieving an understanding of the important role these architectural elements played as avant-garde materials of the time, such as the steel frame, form the basis of this study, since they promoted the evolution of tropical architecture, particularly in Cuba. The design of structural components, facades and interiors were deeply impacted by architectural elements made possible by a cement mix and a mold that allowed for all kinds of forms and shapes and facilitated installation while providing cost competitiveness. During the last decade of the 19th century, both businessmen and artisans from Spain and the United States immigrated to the Hispanic Caribbean. Portland cement products were initially imported from the Old World until the first local cement factories were established. After the Spanish-Cuban-American War of 1898, during a period of economic growth due to the productivity and sales of sugar, there was an increase in construction projects with cement as well as those with structural steel structures as new building materials. The establishment of a temporary government by the USA in Cuba, provided the dawn for industrialization in the region and the immigration of professionals from the construction industry. In the progressive islands of the Spanish Caribbean, the rage for "modernization" increased due to successful structural achievements in the USA by this time, where buildings in cities like Chicago and New York had reached new heights and much lighter structures built with frames made of steel. During this period of experimentation and uncontrolled risk, the use of imported elements to build a steel structure served as a viable substitute for traditional construction. This helped make it the preferred technology for building tall, lightweight structures with fewer interior divisions, large windows, and that were fire and hurricane proof. As a result of these initiatives, between the years 1899-1900, the first overseas branch of American engineers Purdy & Henderson was established in Havana. The efforts and vision of this successful design firm, comprised of talented and experienced engineers and architects, brought them to Cuba, where they could establish themselves with their cutting-edge knowledge and innovative expertise. Little has been written about the important Havana work of P&H, and this thesis fills this gap. The first Cuban projects of this company, which coincided with the founding years of the Republic of Cuba, included multiple buildings with steel structures covered with different architectural materials. Amongst their emblematic structures are the Centro Gallego, the Capitolio, and the Hotel Nacional. Their work included a close collaboration with Cuban architects and engineers, serving as their consultants. Concurrently, P&H added construction and supervision services to this branch of its company, and also included the importation of plumbing materials and project equipment. Their contributions in Cuba (and specifically in Havana), as an important power in the region, deserve the focus of this doctoral thesis. / Cueto De Pantel, BD. (2023).
