Efficacious timing and rate of synthetic fertilizer nitrogen (N) application can reduce the amount of N needed to be applied for potato production. The purpose of this study was to compare combinations of source, timing, and application methods of different synthetic N fertilizers on yield and quality of irrigated Russet Burbank, processing potato in Manitoba. Source, timing, and application method combinations were examined to provide a range of N availability over the growing season. This study was conducted at two sites over two years. Split applications of granular urea or Super-U, addition of ESN at planting and split application of granular urea at planting and fertigation were the most consistent treatments for highest marketable yield and nitrogen use efficiency. ESN was advantageous in wet site conditions. The results indicate split application of granular urea and split granular urea and fertigation that growers of processing irrigated potato primarily use in Manitoba are sound management practices. / February 2016

Many complex decisions require integrating and assessing multiple streams of dynamic information whilst determining how to act. This dynamic information often contains rhythmic structures which our sensory systems can adapt to and use to anticipate future events. Despite the close relationship between rhythmic temporal expectations and complex decision making being self evident, no experiments explicitly attempt to understand this interdependence. If the theories that have emerged from both domains are to generalise to complex interactive behaviour, the effects of dynamic context on complex decisions must be considered. I argue that timing research must move beyond simple decisions and develop a new experimental framework for addressing the problem. This includes increasing the complexity of experimental tasks, testing the effects of timing on perceptual averaging and subjective value decisions, incorporating timing as an inherent dimension of targets, testing degrees of aperiodicity and exploring the effects that prior knowledge about the temporal structure of a stimulus has on choice. Seven behavioural experiments are reported that implement the new experimental framework. Five use a complex auditory-spatial averaging task to examine effects of periodicity, expectation, prior knowledge and related parameters such as IOI variance. One tests the effects of rhythmic variability and stimulus duration on auditory detection to determine specificity to complex decision making, and one investigates the effects of timing on audio-visual subjective value decisions. The results show that existing theories of temporal expectation do not necessarily generalise to complex decision making. Periodicity reduces the amount of information that is needed to form complex decisions. However, the effects of periodicity (or degree of aperiodicity) on choice are dependent on a number of factors associated with prior knowledge, stimulus rate, variance, decision type and task complexity. Using these findings I develop an explanatory framework called "dynamic inhibition and boosting" that better accounts for behavioural data in the literature compared with existing theories. This explanation is supported by the novel proposal that temporal expectations influence confidence and perceived risk.

Time synchronization between systems having no external reference can be an issue in small wireless node-based systems. In this thesis a transceiver is designed and implemented in two separate systems. Then the timing algorithm of "TwoWay Time Transfer" is then chosen to correct any timing error between the two free running clocks of the systems. In conclusion the results are compared towards having both systems get their timing based on GPS timing. / Tidssynkronisering mellan två system som saknar externa referenser kan bli ett problem i små nodbaserade system. I det här arbetet har en sändtagare designats och implementerats i två system. Sedan valdes algoritmen "TwoWay Time Transfer"för att rätta till de timing fel som uppstår mellan systemens separata klockor.I sammanfattningen så jämnförs uppkommna resultat med att ha systemens tid från GPS.

Our studies were divided in three separate analyses. We started looking for 'Market Timing' in the initial public offerings (IPOs) of brazilian firms and later we expanded our studies to the seasoned equity offerings (SEOs). To finish we studied the persistence of 'Market Timing' effects in the capital structure of the companies. Our findings show that brazilian companies issue more equity when the market is hot. This equity issues occur in the IPOs and SEOs and they change the capital structure of the companies. As time goes by, the change in the capital structure tends to reduce. / Este trabalho objetiva verificar a existência de 'Market Timing' no mercado acionário brasileiro. Os nossos estudos foram divididos em três análises distintas. Primeiro verificamos a presença de 'market-timing' nos IPOs e posteriormente expandimos para as ofertas subseqüentes de ações (OSAs). Por último verificamos a persistência dos efeitos do 'Market Timing' sobre a estrutura de capital das empresas. Os resultados dos nossos estudos mostram que as empresas brasileiras tendem a emitir mais capital quando o mercado está aquecido. Essas emissões acontecem através de IPOs e de OSAs e alteram a estrutura de capital dessas empresas. Com o passar do tempo essa alteração na estrutura de capital tende a diminuir.

All eukaryotes have an endogenous circadian (daily) clock that allows for the timing of biological events within the context of the daily light:dark cycle. A wide diversity of plants and animals in temperate regions use photoperiodic (daylength) cues to time life history events, such as reproduction and diapause (insect dormancy) within the context of the yearly seasonal cycles. This dissertation focuses on the relationship between the circadian clock, photoperiodic time measurement and diapause. Chapter I serves as an introduction to biological timing and briefly summarizes the chapters that follow Chapter II outlines why Drosophila melanogaster , the workhorse of modern insect genetics, is not an appropriate system for the study of photoperiodism. Chapter III defines the Nanda-Hamner response, the circadian phenotype used in this dissertation, and proposes that the NH response is due to a rhythmic level of circadian disorganization in response to environmental cycle length. Chapters IV and V deal primarily with the long-held proposition that the circadian clock forms the causal basis of photoperiodic time measurement. I show that variation in the circadian clock does not covary with photoperiodic phenotypes among natural populations of Wyeomyia smithii , and thus these two processes are evolutionarily independent. Chapter VI describes the first forward genetic screen for candidate genes involved in photoperiodism and diapause termination in any animal. Chapter VII is a discussion of the complexity involved in studies of the genetics of photoperiodism and diapause and how historical inertia of scientific hypothesis acts to confound, rather than clarify, the relationship between genotypes and phenotypes. Chapter VIII is a concluding discussion of the implications of the work presented. This dissertation includes both previously published and co-authored material. / Committee in charge: William Cresko, Chairperson, Biology; William Bradshaw, Advisor, Biology; Patrick Phillips, Member, Biology; Eric Johnson, Member, Biology; Stephen Frost, Outside Member, Anthropology
