A Multivariate Test Of Evolutionary Stasis In Homo Sapiens, Jon Geoffrey Kleckner
A Multivariate Test Of Evolutionary Stasis In Homo Sapiens, Jon Geoffrey Kleckner
Dissertations and Theses
In the past, efforts to prove or disprove stasis in hominids have relied upon univariate tests such as Students's t-test. Severe methodological and interpretive problems arise from the misapplication of univariate statistics to questions concerning variation in shape through time. These are questions best addressed using the multivariate approach of morphometrics. Eighteen cranial dimensions drawn from 33 mid and late Pleistocene Homo sapiens were examined using principal component analysis (PCA). PCA divided the sample into two distinct morphologies. Archaic Homo sapiens of the mid Pleistocene clustered with Wurm I neanderthals and apart from post Gottweig early anatomically modern Homo sapiens. …
The Development And Failure Of Historic Agricultural Communities Of Utah: A Case Study Of Johns Valley, Utah, Wayne R. Shelley
The Development And Failure Of Historic Agricultural Communities Of Utah: A Case Study Of Johns Valley, Utah, Wayne R. Shelley
Theses and Dissertations
Many agricultural communities have developed in Utah since the first settlement, but many no longer exist today. Some of these early communities experienced a "boom and bust," while others struggled for several years and were eventually abandoned. Johns Valley is a good example of these historic communities, as it experienced rapid growth and times of success and prosperity, yet it struggled and was eventually abandoned.
The situation in Johns Valley, from its early settlement to its demise, demonstrates the hope of the people who settled there and their efforts to make Johns Valley a productive and successful area. History also …
Virginia's Pelagic Recreational Fishery: Biological, Socioeconomic And Fishery Components, Eleanor A. Bochenek
Virginia's Pelagic Recreational Fishery: Biological, Socioeconomic And Fishery Components, Eleanor A. Bochenek
Dissertations, Theses, and Masters Projects
Catch, effort, fleet size and boat owner expenditure data were collected on Virginia's recreational marlin/tuna fishery for the 1983-1985 seasons. Logbooks, dockside interviews and a telephone survey were evaluated to determine which method was the most efficient and effective for collecting and estimating catch and effort for Virginia's pelagic recreational fishery. In 1984, logbooks were used to collect catch and effort data and fishing effort was estimated using Bochenek's method. Very few fishermen returned their logbooks and as a result this data is probably less reliable than the data collected in other years. Due to the poor return of logbooks, …
