The Quantum World and Cubism

This research explored the Quantum World in addition to using Cubism to create a new visual language. As an artist it is important to pursue new ideas from which to create a new visual language. The Double Slit experiment was the main influence for this work and the idea of the observer. This idea was fascinating yet hard to visualize, so with the use of cubism and some added characteristics I set up a canvas using a cubist portrait and changed it based off of my interpretations of the Quantum World

Perlodidae (Plecoptera) of Wisconsin

The family Perlodidae is one of the most abundant and widespread in the order Plecoptera. These stoneflies occur in a wide variety of clean-water habitats and as indicator organisms have potential for assessing water quality. Studies of this family in Wisconsin prior to 1965 were limited to occasional collections reported by Needham and Claassen (1925) and Frison (1935, 1937, 1942). In 1965 and 1966 a survey of the Wisconsin River and its tributaries yielded nymphs of 11 species of Isoperla (W. Hisenhoff, unpublished report), and later, nymphs and adults of 9 species were found in the Pine-Popple River (Hilsenhoff and Narf 1972). Between 1966 and 1971 additional Perlodidae were collected throughout the state by several persons, many of them by Arvin Krueger while surveying the mayfly fauna of Wisconsin (Krueger 1969)

Effects of excess Nitrogen deposition on Rubus spp. (raspberry) within a central Appalachian hardwood forest

This thesis contributes to on-going research at Marshall University on effects of excess nitrogen (N) deposition on hardwood forests. Excess N can decrease plant biodiversity and enhance loss of nutrients (e.g., Ca++). Preliminary results have suggested that excess N has increased cover of Rubus (blackberry) in the herbaceous layer. The purpose of this study was to quantify the response of Rubus to the N treatment, relating Rubus cover to species richness and using foliar analysis to examine effects on nutrient availability. It is expected that increased Rubus will decrease biodiversity by eliminating N-efficient species, and that added N will simultaneously increase foliar N and decrease foliar cations. Species richness decreased significantly with Nmediated increases in Rubus cover. Foliar tissue contained higher N and lower Ca++ from added N, suggesting loss via leaching with NO3 - . Observed increases of Rubus cover under a closed canopy is novel, considering its intolerance of shad

The effect of formal instruction on the development of sociolinguistic competence: The performance of compliments

Recent research in sociolinguistics and second language acquisition has shown that non-native speakers have considerable difficulty acquiring the rules for communicating appropriately in the target language. Previous efforts to teach learners the rules of speaking have been hampered by insufficient information regarding the linguistic and sociolinguistic rules which govern speech behavior. At present, however, ethnographic research conducted in several English-speaking speech communities has provided detailed descriptions of the compliment speech act sequence and the rules which govern its social distribution, thus making this speech act particularly amenable to formal instruction. At the same time compliments have been shown to be useful social strategies, which, if used appropriately, can help learners enter into and sustain conversations with native English-speaking interlocutors. This study investigated the effect of instruction on the performance of compliments by two groups of adult Japanese females studying English-as-a-second-language at the University of Pennsylvania. Research participants in the tutored group received supplemental instruction biased toward the explicit presentation of the linguistic and sociolinguistic principles for complimenting among speakers of American English. The context for assessing the effect of this treatment was weekly conversational meetings the learners had with American female students over a three-month period. The efficacy of instruction was determined by rating and comparing the productions of compliments and replies by learners in both groups during these interactions. Instruction was shown to have positive effects for learners on five out of seven measures of performance. Learners in the tutored group produced a greater number of compliments, a higher proportion of spontaneous compliments, and a more highly varied adjectival lexicon than did learners in the untutored group. Furthermore, learners in the tutored group replied in a more native-speaker norm-appropriate manner than did learners in the untutored group, and produced longer replies and a greater proportion of replies which helped to sustain the interaction. Secondary findings suggest that instruction interacted the level of English language proficiency, resulting in a higher level of performance by the more advanced learners

Effects of Excess Nitrogen on Biogeochemistry of a Temperate Hardwood Forest: Evidence of Nutrient Redistribution by a Forest Understory Species

Excess nitrogen (N) in terrestrial ecosystems can arise from anthropogenically-increased atmospheric N deposition, a phenomenon common in eastern US forests. In spite of decreased N emissions over recent years, atmospheric concentrations of reactive N remain high in areas within this region. Excess N in forests has been shown to alter biogeochemical cycling of essential plant nutrients primarily via enhanced production and leaching of nitrate, which leads to loss of base cations from the soil. The purpose of our study was to investigate this phenomenon using a multifaceted approach to examine foliar nutrients of two herbaceous layer species in one N-treated watershed (WS3—receiving aerial applications of 35 kg N/ha/yr as ammonium sulfate, from 1989 to the present) and two untreated reference watersheds at the Fernow Experimental Forest, WV, USA. In 1993, we analyzed foliar tissue of Viola rotundifolia, a dominant herb layer species and prominent on all seven sample plots in each watershed. In 2013 and 2014, we used foliar tissue from Rubus allegheniensis, which had become the predominant species on WS3 and had increased, though to a lesser extent, in cover on both reference watersheds. Foliar N and potassium (K) were higher and foliar calcium (Ca) was lower on WS3 than on the reference watersheds for both species. Magnesium (Mg) was lower on WS3 for Viola, but was not different among watersheds for Rubus. Results support the stream chemistry-based observation that excess N lowers plant-available Ca and, to a lesser degree, Mg, but not of K. Foliar manganese (Mn) of Rubus averaged \u3e4 times that of Viola, and was \u3e50% higher on WS3 than on the reference watersheds. A Mn-based mechanism is proposed for the N-meditated increase in Rubus on WS3. Data suggest that excess N deposition not only alters herb community composition and biogeochemical cycling of forest ecosystems, but can do so simultaneously and interactively
