Eric Fitch Daglish (1892–1966): naturalist, illustrator, author and editor
No full text Eric Fitch Daglish (1892–1966) was a naturalist by inclination, a free-lance author and editor in business and, by practice, a wood-engraver of high repute. Taught wood-engraving skills by Paul Nash, he was a close friend also of other famous engravers (John Nash, Eric Gill) within the Society of Wood Engravers. He applied these skills to illustrating his own books for popular audiences on topics ranging from flowers to birds, beasts and the English countryside. Fluent in German, he translated books from that language to supplement his income in the years succeeding the First World War. He is perhaps best known for his bird books: Woodcuts of British birds, The life story of birds and Birds of the British Isles, but was also a prolific writer about dogs. His oeuvre is examined, and his contribution compared with other contemporary bird artists who embraced wood-engraving techniques. A bibliography of his natural history works as author and as editor is included. </jats:p
Dual VP Classes
No full textWe consider the complexity class ACC^1 and related families of arithmetic circuits. We prove a variety of collapse results, showing several settings in which no loss of computational power results if fan-in of gates is severely restricted, as well as presenting a natural class of arithmetic circuits in which no expressive power is lost by severely restricting the algebraic degree of the circuits. These results tend to support a conjecture regarding the computational power of the complexity class VP over finite algebras, and they also highlight the significance of a class of arithmetic circuits that is in some sense dual to VP.Presented at the 40th International Symposium on Mathematical Foundations of Computer Science (MFCS '15).Published as a chapter in: Mathematical foundations of computer science 2015 : 40th International Symposium, MFCS 2015, Milan, Italy, August 24-28, 2015, Proceedings.

Public housing and lethal violence: an analysis of the effect of the presence of public housing on homicide rates
No full textAfter the Second World War, the Department of Housing and Urban Development (HUD) provided funding to local housing authorities to build large scale public housing developments in many cities across the United States. Unfortunately, most of those housing projects were beset with a host of problems as time progressed, including deteriorating building structures, concentrated poverty, racial segregation, and crime. In perhaps no city is this story more heavily studied than in Chicago. Chicago’s public housing tribulations are legendary and are well documented in the academic literature. Many of Chicago’s projects were large high-rise projects located in disadvantaged, isolated, and residentially distinct neighborhoods with strong gang, drug, and crime presence. However, relatively little research has examined the association between Chicago’s public housing and homicide. Specifically, it is uncertain as to whether the unique physical and social environments of public housing developments have an independent effect on lethal violence or whether the high rates of homicides occurring in public housing areas are influenced predominately by neighborhood conditions. Utilizing the Chicago Homicide Data set, this dissertation disentangles the effects of public housing on lethal violence. This study, first, estimated negative binominal regression models to determine the effect of the presence of public housing on tract level rates of homicide. The results of these analyses indicate that the presence of public housing is not a significant predictor of the rates of lethal violence and neighborhood conditions are driving the high rates of homicides occurring in public housing areas. Secondly, the nature of lethal violence occurring in public housing areas was determined by using negative binominal regression and bivariate analyses. Homicides, disaggregated by motive, do not occur at higher rates or disproportionately in Chicago’s tracts with public housing compared to tracts without. The findings from this dissertation indicate that public housing areas do not seem to be micro places that influence a specific type of violence and that neighborhood conditions are driving the high rates of homicide occurring in public housing areas rather than the unique physical and social environments of public housing developments.Ph.

An occupational survey to determine the entry level CAD skills and competencies required by employers of civil engineering technicians in the Northeast Wisconsin Technical College district
No full textIncludes bibliographical references.The purpose of this study was to identify the CAD related technical skills and
competencies that are required for employability at an entry-level position as a civil engineering technician. The majority of employers represented in this study are civil engineering firms, governmental agencies, and surveying firms. Overall, civil engineering firms along with governmental agencies employ the greatest number of drafters. Civil drawings, survey maps, and topographical drawings are the most commonly prepared drawings by the respondents. Other reported drawing types include architectural, electrical/electronic, landscaping, structural, and technical illustrations. Almost all of the respondents use a CAD system for drafting functions. AutoCAD is
the primary CAD platform used. MicroStation is also used, but to a much lesser extent. Of the employers that use CAD software, most use at least one collaborative software package with their primary CAD platform. Eagle Point is the most common collaborative software utilized. AutoCAD Land Development Desktop (ALDD) was noted to be the next commonly used collaborative software. Out of the 24 basic CAD skills that were listed on the survey, 14 were considered to be valid curriculum items and will be either retained or added to the program curriculum. Six of the 24 items will be reviewed for being valid curriculum items, and four of the items will not be included in the curriculum. Overall, most basic CAD skills were performed frequently or considered important. Out of the 29 advanced CAD skills that were listed on the survey, none were considered to be valid curriculum items. Sixteen of the 29 items will be reviewed for being valid curriculum items, and 13 of the items will not be included in the curriculum. Overall, most advanced CAD skills were not performed frequently nor considered important. Out of the 15 basic architectural drawing skills that were listed on the survey, none were considered to be valid curriculum items. Eight of the 15 items will be reviewed for being valid curriculum items, and seven of the items will not be included in the curriculum. Overall, most basic architectural drawing skills were not performed frequently nor considered important. None of the six basic structural drawing skills that were listed on the survey were considered to be valid curriculum items. One of the six items will be reviewed for being a valid curriculum item, and five of the items will not be included in the curriculum. Overall, most basic structural drawing skills were not performed frequently nor considered important

PRIDE IN OUR PRIDES: MITIGATING HUMAN-LION CONFLICT IN THE OKAVANGO DELTA, BOTSWANA
No full textHumans are having marked effects on the natural world, directly contributing to biodiversity declines around the globe. Large carnivores are disproportionately affected as they are wide-ranging, occur in low population densities, and are typically in conflict with humans. Large carnivores are now rare or absent from many ecosystems as their populations have plummeted and human-carnivore conflicts over livestock remain a main contributing factor. The situation is especially acute for the African lion (Panthera leo) as the species is in decline across Africa and has been extirpated from >80% of its historic range. Estimates show the population has decreased by ~90% in the last ~40 years and there are only ~20,000 lions left in the wild, most of which reside in protected reserves. Recently, the population stronghold in the Okavango Delta Region of northern Botswana was also shown to be in decline. This population is one of the largest in southern Africa and is one of only a handful of lion strongholds remaining on the continent. Across five focal villages in the eastern panhandle of the Okavango Delta, I investigated human-lion conflict and established a community-based conflict mitigation program from October 2014 to December 2016. This multilevel study analyzed livestock depredation events, tracked and monitored the local lion population, implemented and tested the efficacy of innovative conflict mitigation strategies, and examined the attitudes of local villagers towards predators and the established conflict mitigation program. Main conflict mitigation strategies included the establishment of an early-warning system linked to the movements of GPS satellite collared lions as well as a predator-proof livestock enclosure building program utilizing locally-sourced materials. Through independent investigations, I found that lions were responsible for ~75% of livestock depredation events in the area and 116 livestock were killed in 102 confirmed wild carnivore attacks. Most (90%) attacks occurred while livestock were unattended and freely grazing in multi-use, communal areas. Valuation of verified losses totaled ~$30,000 over the study period. Additionally, there were 50% more events reported to DWNP for compensation than were confirmed through independent investigations. Five lions (3 males & 2 females) were fitted with GPS satellite collars and home range size varied between the sexes but was not statistically different (males: x̄ = 584 km2, n = 3; females: x̄ = 319 km2, n=2). There was considerable spatial overlap in home ranges as neighboring collared individuals utilized high levels of shared space (female-female overlap: 152 km2, representing 41-56% of respective home ranges; male-male overlap: 125-434 km2 shared space, representing 16-90% of respective home ranges). Lions varied space use temporally to avoid potentially costly interactions with neighboring individuals, and highest levels of overlap occurred during the wet and early dry seasons when flood waters minimized the amount of available land area. In attempt to mitigate human-lion conflict and associated impacts, twelve predator-proof livestock enclosures (“kraals”) were constructed from locally-sourced mophane (Colophospermum mopane) trees and villagers were shown how to construct the kraals for themselves. While they received strong reviews from villagers, only 66% of constructed kraals were regularly used to protect livestock overnight. Lion alert early-warning messages were dispersed throughout the villages when GPS satellite collared lions moved into areas of high livestock or human use. Collars were programmed with two “nested” electronic geofences denoting livestock grazing lands and village lands, enabling an email and text message notification to program staff who could then issue lion alert early warning to affected local stakeholders (within 5-8km of the breach location). Eighty-seven lion alerts (out of 101 geofence breaches) were dispersed to village headmen and elders and then passed throughout the community via a branching “phone tree”. The automated collar breach notification system was often delayed (x̅ = 8 hours), inhibiting the distribution of lion alert messages. Villagers responded favorably to the lion alert program, though only 36% of surveyed farmers had actually received an alert by the end of 2016. In pre- (n = 201) and post- (n = 208) assessment interviews, 50% of farmers reported losing livestock to wild carnivores and respondents had strong negative attitudes towards lions and other carnivores in general. However, over the course of the study, villagers noted an increase in their tolerance of lions and an increase in the belief that coexistence with lions is possible. Respondents had negative attitudes towards the government-run compensation program, citing low and late payments, but were supportive of our mitigation strategies. Despite challenges encountered here, these efforts show targeted, intensive conflict management can positively impact stakeholder tolerance of carnivores, and with some updates and modifications this project can serve as a model for other systems where high levels of human-wildlife conflicts exist.Environmental ConservationDoctor of Philosophy (Ph.D.

Assessing Wild Canid Distribution Using Camera Traps in the Pioneer Valley of Western Massachusetts
No full textWith the ever-increasing human population, more people reside in urban areas than ever before; this is having marked effects on the landscape and in turn, wildlife. This study uses automatically triggered wildlife cameras to assess the distribution of three carnivore species (coyotes, Canis latrans; red foxes, Vulpes vulpes; and gray foxes, Urocyon cinereoargenteus) around the Pioneer Valley of Massachusetts in relation to a gradient of human development. Cameras were placed at 141 locations within the 320-km2 study area over the course of three field seasons (3,052 trap nights). Relative abundances for fourteen other species and site characteristics (e.g., elevation, forest cover type, distance to urban edge) for each camera location were determined to develop a generalized linear model for the distribution of each species across the study area. Coyote distribution was most affected by the relative abundances of their prey species and not by landscape characteristics or sympatric carnivore species. Coyotes are the top predator in the area and therefore their distribution is correlated with the relative abundances of their prey species, unlike other parts of their range where they are controlled by larger carnivores. Red and gray foxes both had negative relationships with the relative abundance of coyotes as coyotes have been shown to adversely impact fox distributions and access to resources. Both red and gray foxes were also negatively or uncorrelated with increased levels of urbanization, which is both supported and refuted by published literature and is likely system specific.Master of Science (M.S.
