Underwater decomposition: an examination of factors surrounding freshwater decomposition in eastern Massachusetts

Westling, Lauren January 2012 (has links)
Thesis (M.S.)--Boston University / This study investigated the decomposition of three pig (Sus scrofa) carcasses in the same body of water under lentic and lotic conditions and at variable depths in a temperate mixed forest in the Outdoor Research Facility (ORF) in Holliston, Massachusetts in the summer months of June and July. Data were collected on the invertebrate activity, scavenger activity, water and ambient temperature, stages ofbody decomposition, and the rate of decomposition for each set of remains. Accumulated degree days (ADD) and total body scores (TBS) were used to determine two equations, differentiated by their microhabitat, with the potential use of estimating the postmortem submergence interval (PMSI) in death investigations under similar conditions. The aquatic remains reached skeletonization in 45 days and the terrestrial control remains in 14. Terrestrial and aquatic invertebrate activity was extensive both above and below the waterline with 42 families from 17 orders collected and identified. Through the use of motion detector cameras the researcher was able to view the activities performed around the remains by a blue heron, a coyote, a raccoon, multiple black vultures, multiple turkey vultures, multiple squirrels, and multiple American bullfrogs.

Relational Trust, Social Connections, and Improving Principal Practice: One District’s Implementation of the Massachusetts Model System for Educator Evaluation to Support the Growth and Development of Principals

Carter, James Alden January 2016 (has links)
Thesis advisor: Joseph O'Keefe / Thesis advisor: James Marini / Using social capital theory as a conceptual framework, this qualitative study of one Massachusetts district analyzed how principals’ relational trust and interconnectedness with central office administrators (COAs) correlated with their perceptions of district efforts to support their growth and development. Data included interviews with principals and COAs and document analyses. Findings revealed a decided split among principals, with some reporting high trust levels and close connections with COAs and others reporting distrust and isolation. Of the district’s five major initiatives designed to support principals, two were perceived positively by most principals, two received mixed reactions with connected principals more favorable than isolated principals, and one received widespread negative perceptions. District initiatives widely perceived to be effective mirrored principal goals, provided opportunities for COA direct assistance, and were structured to facilitate the development of professional assistance relationships. Conversely, the initiatives with mixed or negative perceptions lacked such relationship-building opportunities. / Thesis (EdD) — Boston College, 2016. / Submitted to: Boston College.

The American Dream in Flux: Brazilian Immigrants’ Experiences of Living, Working and ‘Becoming’ American

Spencer, Anne Marie January 2012 (has links)
Thesis advisor: Danielle Hedegard / There are an estimated 150,000 Brazilians currently in the state of Massachusetts living, working, and living as immigrants in the “nation of immigrants” (McDonnell and de Lourenco, 2009; p. 241). The population often goes unnoticed, lost among a sea of immigrants in the landscape of Massachusetts. Occupying sub jobs, these Brazilian immigrants very often lose their status, and voices in the process of immigration to the United States. Over time, many Brazilians are able to achieve economical and occupational success in Massachusetts and decide to make the United States their home. Guided by the research questions: “How do Brazilian immigrants’ perceptions of the American Dream change with respect to reality and their lived experiences?” and “What are the lived experience of Brazilian immigrants?” I intend to understand this transition from temporary immigrant to permanent resident, and how the American Dream plays into these shifting expectations. / Thesis (BA) — Boston College, 2012. / Submitted to: Boston College.

Geochemical Tracers of Surface Water and Ground Water Contamination from Road Salt

Anderson, Jacob January 2013 (has links)
Thesis advisor: Rudolph Hon / The application of road de-icers has lead to increasing solute concentrations in surface and ground water across the northern US, Canada, and northern Europe. In a public water supply well field in southeastern Massachusetts, USA, chloride concentrations in ground water from an unconfined aquifer have steadily risen for the past twenty years. The objectives of this study are to understand spatial and temporal trends in road salt concentrations in order to identify contamination sources and fate. To this end, the methods of this project include field and lab work. Water samples were collected from surface, near-surface, and ground water from March 2012 to March 2013. The other major field data are specific conductance measurements from probes located in three piezometers. In the lab, all samples were analyzed for major ions with ion chromatography analysis. Additionally, trace elements were measured by inductively coupled plasma analysis on a subset of samples. The results of these hydrogeochemical procedures showed several important trends. First, the highest concentrations of sodium and chloride from near-surface samples were located near to roadways. Second, ground water samples taken from glacial sediments contained relatively high concentrations throughout the water column, whereas ground water samples from wetlands had high concentrations only near the surface. Third, there was no clear relationship between pH and cation concentrations. Finally, specific conductance data showed strong seasonal trends near to the surface, whereas values taken from deeper in the aquifer were steadily increasing. Based on these results, it is highly probable that road salt application is the dominate contamination source. The pathways of road salt in the watershed include runoff into surface water and infiltration into the vadose zone and ground water. Road salt appears to preferentially travel through glacial features rather than floodplain features. It is possible that sodium from road salt is sorbed to aquifer sediment and displaces other cations. However, the low values of trace metals suggest that cation exchange is not mobilizing heavy metals. Finally, the increasing specific conductance values deep in the aquifer suggest that road salt is retained within the aquifer and concentrations will likely increase in the future if the current road salt application procedures are continued. / Thesis (MS) — Boston College, 2013. / Submitted to: Boston College.

Optimization of State Revenues through the Introduction of Casino Gambling

Kang, Bryan January 2003 (has links)
Thesis advisor: Richard McGowan / This thesis will try to determine whether any state could benefit from the introduction of casino gambling, and if so, how much extra funds could be expected. Massachusetts residents spend an estimated $620 million at Connecticut's two casinos -- Foxwoods and Mohegan Sun, and they are dropping an additional $726 million at out-of-state gambling facilities each year. If this sum were to be spent in-state, Massachusetts would be able to reap a significant percentage of that amount for its state revenues. The same can be said for Rhode Island. West Warwick, Rhode Island is merely 45 minutes away from Foxwoods, and Mohegan Sun is about an hour away, and for a state with a huge deficit, the profit that RI could reap from an instate casino could make the introduction of casinos a worthwhile venture. / Thesis (BA) — Boston College, 2003. / Submitted to: Boston College.

Whittredge, Harland V. January 1952 (has links)
Includes handbook in pocket. Thesis (M.A.)--Boston University / In September 1951, the superintendent of schools in Wilmington, Massachusetts, and the director ot guidance had a conference to determine methods of increasing the effectiveness ot the guidance program in the high school. Among the topics considered was that of pupil orientation. Various means ot orientation were discussed and several proposed plans were adopted. Among the guidance devices chosen tor development was a student handbook. The writer was placed in complete charge ot the program, including the preparation and publication ot the handbook.
