abstract: The strips in Mark's Feminist Froze to Default in an Implementation String transfer the lives of feminists absent and imagined, overbearing and empathetic--cross dressers, lethal injectors, expats, planets, and Canadian survivalists--in an autumn to characteristic, unsettle, and reassess controller utterances of masculinity. / Dissertation/Thesis / Masters Thesis Creative Writing 2015

Orientador: Jose Carlos Barbosa / Coorientador: Antonio Carlos Busoli / Banca: Arlindo Leal Boiça Júnior / Banca: Marcos Gino Fernandes / Resumo: Os percevejos são importantes pragas da soja, e o conhecimento de sua bioecologia e distribuição na cultura, é indispensável para realizar amostragens e determinar o nível de controle. O objetivo do trabalho foi estudar a distribuição espacial de Euschistus heros na cultura da soja em cultivar de soja convencional e transgênica e elaborar um plano de amostragem sequencial. O experimento foi conduzido no ano agrícola 2010/2011, na FCAV/Jaboticabal/SP/Brasil, em dois campos de 10.000 m2, subdivididos em 100 parcelas de 10 m x 10 m. As cultivares semeadas foram M 7908 RR e M-SOY 8001. As amostragens foram semanais, sendo anotado o número de ninfas do 1o ao 5º ínstar e o número de adultos. Para estudo da dispersão dos insetos na área, foram utilizados os índices: razão variância/média, índice de Morisita, Coeficiente de Green e expoente k da distribuição Binomial Negativa. Para estudo dos modelos probabilísticos que descrevem a distribuição espacial dos insetos, foram testados os ajustes às distribuições de Poisson e Binomial Negativa. As ninfas de 1º ao 3º ínstar apresentaram distribuição espacial agregada, ninfas de 4º e 5º ínstar, adultos e ninfas de 4º e 5º ínstar mais adultos, apresentaram variação na disposição, de moderadamente agregada à aleatória. No teste de ajuste às distribuições de probabilidade, o modelo de distribuição Binomial Negativa obteve ajuste para ninfas de 1º ao 3º ínstar, ninfas de 4º e 5º ínstar, adultos e ninfas de 4º e 5º ínstar mais adultos. Foi elaborado um Plano de Amostragem sequencial para percevejos de 4º e 5º ínstar ninfal e adultos, e o número máximo de unidades amostrais para se tomar a decisão foi nove / Abstract: The stink bugs are important pests of soybean, and the knowledge of their bioecology and distribution in the culture is essential to carry out sampling and determine the control level. Thus, this work aimed to study the spatial distribution of Euschistus heros on transgenic and conventional soybean cultivars, and develop a sequential sampling plan. The experiment was conducted during 2010/2011 agricultural season, in FCAV/Jaboticabal/SP/Brazil, in two 10,000 m2 fields, divided in 100 equal 10 m x 10 m plots. The cultivars seeded were M 7908 RR and M-SOY 8001. Samplings were realized weekly, and the number of first to fifth instar nymphs and the adults were recorded. The follow indexes were used to evaluate the insects dispersion in the area: variance/ mean relationship, Morisita's index, Green's coefficient and exponent k of Negative Binomial distribution. For the probabilistic models studies that describe the spatial distribution of insects, were tested the adjustments of Poisson distributions and Negative Binomial. The first to third instar nymphs showed aggregated spatial distribution; fourth and fifth instar nymphs, adults and fourth and fifth instar nymphs plus adults showed variation from moderately aggregated to random in disposition. On the adjustment to probability distributions test, the Negative Binomial distribution model fitted for first to third instar nymphs, fourth and fifth instar nymphs, adults and fourth and fifth instar nymphs plus adults. A sequential sampling plan was builted for fourth and fifth instar nymphs plus adults. The maximum number of sample units to make the decision was nine / Mestre

On the basis of his study of the female genitalia, Scudder (1959) suggested that in the Heteroptera-Hemiptera, the families Saldidae and Mesoveliidae might be closely related; the present morphological study was undertaken to determine whether a study of other characters also supports their inclusion in a natural group. In these two families, comparison of the head structures revealed that they are quite distinct. The thorax revealed two types: a Saldula type, and a Mesovelia type, and since it is shown that the structure of the thorax is of little taxonomic value in distinguishing the suprafamilial categories, it was considered that the differences between the Saldidae and the Mesoveliidae need not necessarily indicate a fundamental taxonomic difference. In the abdomen, the presence of the clasping organ in the Saldidae completely separates this family from the Mesoveliidae, The present study shows that the Saldidae and the Mesoveliidae are not closely related as might be inferred from comparisons of the female genitalia; they are quite distinct morphologically. The taxonomic position of the two families was also considered. Most authorities believe that the Mesoveliidae are appropriately placed in the Amphibicorisae, and this is supported by the present study. The position of the Saldidae, on the other hand, has heretofore been very uncertain since this family shows some Pentatomomorph features as well as some Cimicomorph features. Two alternatives have been suggested in this thesis regarding the systematic position of the Saldidae. According to the first, the Saldidae may be considered a Cimicomorph which branched off from the main stem of Cimicomorpha, and subsequently developed Pentatomomorph characters - an assumption which presupposes that parallel evolution has occurred. Alternatively, the Saldidae may be considered a branch of the Pentatomomorpha, which arose after the evolution of some Pentatomomorph characters, but before the evolution of the complete Pentatomomorph complex of characters. This latter alternative takes cognisance of the fact that the Pentatomomorph complex of characters evolved gradually and not by a single 'saltation'. It has been concluded, however, that the data available at present are not sufficient to enable one to state which of the two alternatives mentioned above is the correct one, although I am inclined to consider the former as the more plausible. In addition to the foregoing, two general aspects of the morphology of the Heteroptera were considered, namely the interpretation of the head sclerites and the variation in the thoracic structure between apterous and macropterous forms of the two families. / Science, Faculty of / Zoology, Department of / Graduate

A 4.6-fold increase in the bimass of Cliona delitrix infesting Montastrea cavernosa substrate occurred in a portion of the Grand Cayman fringing reef affected by the discharge of untreated fecal sewage.It is suggested that the 6.3-fold increase in bacteria biomass (both coliforms and natural marine bacterioplankton) is linked to the sponge proliferation at the polluted site. Since demosponges normally obtain much of their nutritional needs from URPOC and only 11 from bacteria, the significance of the elevated bacteria count may be limited to its importance as a flag as an indicator of untreated sewage effluent. At the polluted study site, Montastrea cavernosa exhibited a 451 reduction in the amount of substrate occupied by living polyps.The loss of this respiring coral biomass is probably not compensated for by the biomass increases of C. delitrix and of the microflora inhabiting the dead substrate.The increased C. delitrix biomass reflects a. similar increase in the amount of M. cavernosa skeleton that has been eroded and reduced to silt-sized sediment. Thus, the discharge of untreated sewage into the reef environment can have a profound effect upon the trophic distribution of reef fauna, leading to a disturbance of the precarious balance between carbonate production and destruction on the reef. / Thesis / Bachelor of Science (BSc)

The tribe Leucophoropterini (Miridae: Phylinae) is a diverse assemblage of primarily Indo-Pacific and Australian bugs which are united by simple, small genitalia and a trend towards ant-mimetic body forms. Previous to this work, the relationship of the Leucophoropterini to the other tribes of Phylinae, as well as the generic relationships within the lineage, was unresolved. Further, the characters initially proposed to unite the tribe are brought into question with the addition of several recently discovered taxa from Australia. The Leucophoropterini is first re-evaluated within a phylogenetic analysis of the subfamily Phylinae, using a combined molecular and morphological dataset to test the monophyly of the lineage, re-test the character synapomorphies supporting it, and to determine the closest relatives to the tribe. The molecular dataset includes 4 genes (COII, 16S, 28S, and 18S), and 123 morphological characters for 104 taxa, which is analyzed in a parsimony analysis using Tree analysis using New Technology [TNT], a model-based analysis in RAxML, and a Bayesian analysis in Mr. Bayes. All three methods resulted in phylogenetic trees with nearly identical generic and tribal groupings, and a lineage containing Pseudophylus Yasunaga, Decomia Poppius and Tuxedo Schuh being sister-group to the Leucophoropterini. With the closest relatives to the Leucophoropterini determined for outgroup selection, a generic revision of the tribe including both Australian and Indo-Pacific taxa is accomplished using 137 morphological characters and is analyzed in an un-weighted and implied weighted parsimony analysis using TNT for 86 leucophoropterine taxa. The Indo-Pacific taxa of Leucophoropterini are found to be related to the Australian Leucophoropterini, and at least two genera within the tribe (Sejanus Distant, Leucophoroptera Poppius) were found to be paraphyletic. Lastly, taxa are revised within the context of the generic-level phylogenetic analysis, with new genera and species from Australia and the Indo-Pacific being described.

4 pp. / Bed bugs can cause anxiety, bite reactions, and financial hardship. The University of Arizona Community IPM Program and partnering research institutions are working to battle the recent bed bug resurgence. Researchers hope to determine the real social cost of bed bugs, as well as the significant causes of infestations. Integrated Pest Management (IPM) approach is the most likely strategy to result in successful elimination of bed bugs.

Legacy applications, often written in C, can be riddled with bugs. Sarcastically referred to as "veritable bug ranches", pre-existing legacy applications of substantial size and complexity are still commonplace. In this dissertation, I motivate, build and evaluate Lind, a sandbox for legacy applications. Lind decreases the impact of buggy programs on the system that runs them. It does this without changing their code or destroying the non-functional characteristics of the programs---such as performance, portability, light-weightedness and ease of deployment---which are the primary motivators for legacy software written in C. Lind borrows many principles of secure system design to help it isolate legacy applications so they cannot impact the rest of the system. To assess Lind, I evaluate how well legacy applications perform in Lind, how strong the isolation Lind provides is, and how easy it is to port applications to Lind---all to conclude that Lind is a viable proof-of-concept platform for legacy applications. / Graduate / 0984

The common bed bug has reemerged as a major pest in the United States. Pest management professionals need reliable up-to-date information on how to manage bed bug infestations. My study was intended to evaluate the efficacy of several insecticides currently labeled for bed bug control. In product efficacy tests, field strain bed bugs were found to be 99-450 times less susceptible than laboratory strain bed bugs to several pyrethroid products. The non-pyrethroid products tested, chlorfenapyr and a non-toxic desiccant dust, killed laboratory strain bed bugs, but were extremely slow acting taking greater than 9 days to kill 50%. None of the insecticides tested, including the pyrethroids, were repellent to laboratory or field strain bed bugs. A field test was conducted comparing 2 pesticide treatments regimens (traditional and novel) for bed bug control in low income apartments. Both the traditional and novel combinations caused significant reductions in bed bug populations. Both treatments reduced the number of bed bugs by the end of the test period, but neither treatment combination completely eliminated the bed bug infestations, even after an average of 1.3 gallons of product was applied in each apartment. Laboratory assays were conducted to determine the effect of hydroprene exposure on bed bug development. Although hydroprene did not appear to interfere with nymphal development, fifty percent of the bed bugs died during the final molt. The bed bugs which survived to adulthood showed no reduction in fecundity when compared to control groups. / Master of Science in Life Sciences
