This thesis establishes the earliest appearance of ground slate points at 50 locations throughout the Northwest Coast of North America. Ground slate points are a tool common among maritime hunter-gatherers, but rare among hunter-gatherers who utilize terrestrial subsistence strategies; ground slate points are considered one of the archaeological hallmarks of mid-to-late Holocene Northwest Coast peoples. The appearance of ground slate points in the archaeological record is frequently marked by a concurrent decline in the prevalence of flaked stone points, a phenomenon often referred to as "the ground slate transition." Until now, the specific timing of the appearance of these tools has been ill-defined, and a number of competing theories have arisen to explain the apparent preference for ground slate points over flaked points by prehistoric peoples. By drawing upon a sample of 94 artifact assemblages from 50 sites in Alaska, British Columbia, and Washington, I have constructed a database of artifacts counts, provenience information, and radiocarbon dates which allows for inter-site comparisons of the earliest appearance of the technology. My research has identified a general north to south trend in the appearance of slate points; which begin to appear in the archaeological record around 6,300 cal BP in southeast Alaska, to 2,900 cal BP in Puget Sound. There are notable exceptions to this pattern, however. Given that these data are drawn from both cultural resource management reports and academic literature, I have qualified these findings by addressing some of the common problems of making inter-site comparisons, such as the comparability of radiometric dates, which I address by undertaking a radiocarbon hygiene program. The chronology constructed here provides an important tool for evaluating theories about the ground slate transition, and thereby aiding in untangling the link between aquatic subsistence strategies and technological decision making.

Thesis advisor: Noah P. Snyder / Multi-temporal elevation (MTE) analysis is used to study topographic changes at specific intervals. Barrier-island complexes are often studied using this MTE analysis to quantify changes to the environment after hurricanes to understand how dynamic landscapes respond to different forcings. The Sandy Pond spit (SPS) is a north-south trending barrier island on the eastern shore of Lake Ontario, New York, which responds dynamically to fluctuations in water levels, ice cover, and storms. Prior research reconstructed the geomorphic history of the SPS from 1878-2013, determining that the most significant factor affecting decadal change is the lake-water elevation. In the summers of 2017 and 2019, anomalously high precipitation and lake levels resulted in increased erosion along the SPS, and flooding in neighboring communities. In this study I used shoreline position, foredune crest position and elevation and volume of deposition and erosion to determine the dominant force of geometric change on the SPS before, during and after the high water events in 2017 and 2019, using the study period 2001-2020. Lidar data and small uncrewed aerial system images are used to generate digital elevation models (DEMs) and DEMs of difference (DoDs) from surveys conducted in May 2001, July 2007, June 2011, October 2015, May 2018, September 2018, July 2020 and August 2020. Results indicated water level was the most significant factor altering the topography of the SPS. Large storm events although erosive, were not as destructive to the shore environment as the long duration elevated summer water levels. From 2001-2015 the shoreline advanced an average of 0.25 m/year. From 2015-2018 and 2018-2020 the shoreline retreated 0.62 m/year, and 3.27 m/year respectively. The foredune position and elevation altered due to erosion of the dune toe caused by wave action and shoreline retreat from 2015-2020 compared to 2001-2015. To study volumetric changes, the SPS was split into seven ecogeomorphic zones that characterize the barrier-spit system at large. From 2007-2015 net deposition was recorded at five of the seven zones when applying a 95% confidence interval. The zones recording erosion were characterized by high dune complexes with sparse vegetation to anchor sand. From 2015-2018 net erosion was recorded in all seven zones, indicating water level had a statistically significant effect on the rate and volume of geomorphic change to this ecosystem. / Thesis (MS) — Boston College, 2022. / Submitted to: Boston College.

We'd Love to Have You on Our Show is a collection of short fiction preceded by a critical introduction. The stories share a thematic bond in that that all of the protagonists are either obsessed with or could be guests on talk shows. The introduction, "The Meaning of Yearning" explores how Robert Olen Butler and Denis Johnson have influenced me as a young writer attempting to write interconnected, character-driven stories. The introduction begins by chronologically showing how I wrote and then how I changed from workshops to writing this thesis, and it concludes by examining character, theme, and humor throughout Butler's, Johnson's, and my own stories.

Assessing the spatial and temporal distributions of marine turtles in an open system poses both observational and analytical challenges due to their migratory nature and use of large current systems. Concentrations of animals can shift because turtles undergo large-scale migrations and habitat shifts seasonally as well as a function of lifestage. Surface counts of marine turtles in waters off Florida’s east coast were made in and adjacent to the Florida Current using standard aerial surveys. While it is understood that marine turtles use waters off the eastern coast of Florida, here we document the magnitude of the shift in turtle presence each season throughout a two year study and identify habitat characteristics where turtles occur most frequently. Our assessment of marine turtles in the waters off southeast Florida provide valuable metrics describing the in-water biology of sea turtles in this area to inform future management strategies of these endangered species. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection

This survey sought to determine the public perceptions and knowledge of counsellors on the Gold Coast and Northern New South Wales. Comprising of two studies, this paper extended on previous research conducted by Rogers and Sharpley (1983), Sharpley, Rogers and Evans (1984), and Sharpley (1986). Study I included a representative sample of 226 members of the general public, plus a sample of 105 medical practitioners. Respondents were asked to complete a 24-item questionnaire regarding their perceptions and knowledge of counsellors. Four questions were designed to investigate whether or not distinctions could be made between counsellors, psychologists, psychiatrists and social workers. An additional seven questions were included for only medical practitioners to answer and sought to determine whether or not, and under what circumstances, medical practitioners would refer to a counsellor. These questions were also concerned with establishing what value medical practitioners would place on having a counsellor working as a team member of their practice.The results of Study I indicated that both the general public and medical practitioners viewed counsellors positively. Results further showed that the confusion and lack of knowledge reported by respondents from the last Australian study conducted by Sharpley (1986), was no longer evident. Study II was designed to assess the validity of the reported sources that respondents from Study I indicated that they would utilise in order to access a counsellor. Three samples were involved in Study II. The first sample comprised of 60 medical receptionists, the second sample included 25 counsellors listed in the yellow pages telephone directory, while the third sample involved 6 community centres listed in the yellow pages telephone directory. However, the results of Study II showed that counsellors were not as readily accessible from these sources as was perceived by respondents from Study I. Hence, it could be concluded that counsellors need to involve themselves with promotion and education if they are to maintain the positive regard indicated by the respondents of this study.

This study considers relocatable homes as an alternative housing choice for male and female retirees fifty years of age and over. Homogeneous parks and estates planned for a specific type of relocatable home are compared with those which evolved from tourist parks and retain sites for both permanent and short-term occupancy. Four relocatable home environments are considered: caravan parks, mobile homes in mixed parks, manufactured homes in mixed parks and manufactured housing estates. The differential effects of 'age', 'house type' and 'housing environment' upon 'residential satisfaction', 'sense of community within the neighbourhood', 'social integration in the community' and 'psychological adjustment' form the analytical framework of the study. Residents of 34 parks/ estates on the North Coast of New South Wales completed 778 questionnaires. Case studies, interviews, letters and written comments provided data for qualitative analysis. Approximately 94% of respondents are satisfied with their homes and housing environments. Residential satisfaction is most influenced by the interactions and perceptions of residents; psychological adjustment is influenced by a positive attitudes towards self and one's neighbours; integration in the community is affected by levels of network. Each of these relate strongly with having a sense of community in the neighbourhood. Space internal to the dwelling relates to satisfaction, adjustment and community integration. External space relates to the need for a well planned neighbourhood which affords privacy, safety and amenities. The need for meeting places for small and large groups was recurrent. The results suggest that residents of relocatable homes tend to retain affiliation with organisations joined prior to relocation. They are not reliant on their new neighbours to integrate in their community. This result is contrary to prior research which studied site built homes and traditional neighbourhoods. The present high levels of residential satisfaction would rise if it were not for the overwhelming uncertainty of tenure and unjustifiable rises in site rent. The study reviews government policy especially in relation to tenure. A relocatable home offers no more affordability than a site-built home in the same area in the long-term but it does offer a preferred retirement lifestyle.

The continental terrace west of Oregon between 43° 50'N and 44° 40' N latitude is 50 to 55 miles wide. It consists of a continental shelf, 16 to 35 miles wide, and a continental slope, 16 to 37 miles wide. The eastern portion of the shelf is a smooth, sediment covered area that slopes very gently west. The western portion of the shelf contains four rocky bank areas. The banks are topographically irregular and appear to be of structural origin. West of the banks the shelf edge occurs at depths of 71 to 90 fathoms. The continental slope extends from the edge of the shelf to the abyssal plain at depths of 1530 to 1610 fathoms. A smooth upper slope of less than three degrees extending to depths of 117 to 250 fathoms occurs north and south of Heceta Bank. West of Heceta Bank the upper slope is formed by a scarp that slopes 10° to 16° to 560 to 725 fathoms. West of the upper slope there is an area of irregular topography, including benches, hills and scarps, which extends to depths of 380 to 1100 fathoms. The lower part of the slope is formed by a north-striking scarp which is 3000 to 6000 feet high and slopes 04° to 15°. The bathymetry indicates that the continental slope was formed by step-type, block faulting. Sediments form a thin surface layer over much of: the terrace. Detrital sand, similar to the coastal sand, covers the shelf from the shoreline to approximately 50 fathoms. The deeper areas on the shelf and upper part of the slope are covered by glauconitic sands and silts on the topographic highs and olive green, clayey silts in the topographic lows. The intermediate and lower portions of the slope are blanketed with olive-green, clayey silt. In these sediments the sand fraction, which generally comprises less than five percent of the sample, is composed chiefly of diatoms, Foraminifera, Radiolaria, and sponge spicules. Sands are also present on the intermediate and deep portions of the slope. Dredge hauls west of Newport obtained sand composed mainly of detrital grains which may have been derived from an underlying friable sandstone. Thin layers of sand occur in cores from other portions of the slope. These sands may have been derived by down slope movement of sediment from the upper slope and the shelf. Sedimentary rocks of Upper Miocene and Pliocene age crop out on the shelf banks and on the continental slope. The banks consist of a sequence of diatomaceous, clayey siltstones with interbeds and concretions of calcareous siltstones. Glauconite sandstone, gray wacke sandstone, and limestone breccia are exposed along with the siltstone, on the northern end of Heceta Bank. Most of the rocks obtamed from the slope are similar to those from the shelf. Friable, wacke sandstone is exposed on the slope west of Newport. Foraminifera, the sand fraction compositions, and textural analyses all indicate that the sediment forming the siltstones from the shelf were deposited at lower littoral to lower bathyal depths. The sediments forming the rocks were deposited in one or more sedimentary basins during the Miocene and Pliocene. The subsidence continued until the. Late Pliocene when the area began to rise. The area was uplifted as much as 1000 fathoms by the Late Pleistocene when the shelf was eroded by transgressions and regressions resulting from sea level changes. The last rise in sea level resulted in the erosion of the shelf to its present form and the deposition of a thin layer of sediment. Sand is presently being deposited on the shallow areas adjacent to the continent, and silt and clay are being laid down on the slope and the sheltered areas of the outer shelf. / Graduation date: 1965
