Black Labor at Pine Grove & Caledonia Furnaces, 1789-1860

Black labor operating under various degrees of freedom found a suitable working environment, if not a safe haven, in several iron forges of South Central Pennsylvania, from the late 1790s through the 1850s. Primary accounts indicate that two in particular, Pine Grove Furnace of Cumberland County, and Caledonia Furnace of Franklin County, harbored runaway slaves to augment their work force. Pine Grove records, dating from 1789 – 1801, specify names of “negro” employees, verifying that black labor coexisted with white, but day books, journals, and ledgers do not denote status.1 Whether they were free men, or slaves rented out by Pennsylvania slave owners, or runaways from the South cannot be gleaned from the day books. All three combinations were possible, especially in the 1790s. Circumstantial evidence suggests that escaped slaves did bolster the ranks of both forges until 1860. With renowned abolitionist Thaddeus Stevens in ownership of Caledonia, and proprietors sympathetic to the same cause at Pine Grove, the environment favored Underground Railroad activity. When this circumstance is coupled with the presence of a Quaker Meeting House in northern Adams County, and the recognition that both forges were within a thirty mile radius of the Maryland slave-state border, then a recipe existed for hide-outs to be employed in area furnaces.

Fish assemblages found in tidal-creek and seagrass habitats in the Suwannee River estuary

Fish assemblages were investigated in tidal-creek and seagrass habitats in the Suwannee River estuary, Florida. A total of 91,571 fish representing 43 families were collected in monthly seine samples from January 1997 to December 1999. Tidal creeks supported greater densities of fish (3.89 fish/m2; 83% of total) than did seagrass habitats (0.93 fish/m2). We identified three distinct fish assemblages in each habitat: winter−spring, summer, and fall. Pinfish (Lagodon rhomboides), pigfish (Orthopristis chrysoptera), and syngnathids characterized seagrass assemblages, whereas spot (Leiostomus xanthurus), bay anchovy (Anchoa mitchilli), silversides (Menidia spp.), mojarras (Eucinostomus spp.), and fundulids characterized tidal-creek habitats. Important recreational and commercial species such as striped mullet (Mugil cephalus) and red drum (Sciaenops ocellatus) were found primarily in tidal creeks and were among the top 13 taxa in the fish assemblages found in the tidal-creek habitats. Tidal-creek and seagrass habitats in the Suwannee River estuary were found to support diverse fish assemblages. Seasonal patterns in occurrence, which were found to be associated with recruitment of early-life-history stages, were observed for many of the fish species

Nonlocal van der Waals density functional: The simpler the better

We devise a nonlocal correlation energy functional that describes the entire range of dispersion interactions in a seamless fashion using only the electron density as input. The new functional is considerably simpler than its predecessors of a similar type. The functional has a tractable and robust analytic form that lends itself to efficient self-consistent implementation. When paired with an appropriate exchange functional, our nonlocal correlation model yields accurate interaction energies of weakly-bound complexes, not only near the energy minima but also far from equilibrium. Our model exhibits an outstanding precision at predicting equilibrium intermonomer separations in van der Waals complexes. It also gives accurate covalent bond lengths and atomization energies. Hence the functional proposed in this work is a computationally inexpensive electronic structure tool of broad applicability

Dynamic interaction between tectonic plates, subducting slabs, and the mantle

Mantle convection models have been formulated to investigate the relation between plate kinematics and mantle dynamics. The cylindrical geometry models incorporate mobile, faulted plate margins, a phase change at 670 km depth, non-Newtonian rheology, and tectonic plates. Models with a variety of parameters indicate that a relatively stationary trench is more likely to be associated with a subducted slab that penetrates into the lower mantle with a steep dip angle. However, a subducted slab that is deflected above the 670-km phase change with a shallow dip is more likely to be associated with a margin that has undergone rapid retrograde trench migration. This relation between slab morphology and plate kinematics is consistent with seismic tomography and plate reconstruction of western Pacific subduction zones. The efficiency of slab penetration through the 670-km phase change is controlled by both the buoyancy of the subducting plate and the mobility of the overriding plate. While older subducting plates have a greater propensity for slab penetration, trench mobility reduces the propensity for slab penetration. Smaller overriding plates have a greater mobility. When subducted slabs approach the bottom thermal boundary layer, hot fluid is pushed aside, and plumes form on the periphery of slab accumulations. There are sharp temperature contrasts between the subducted slab and the thermal boundary layer at the core mantle boundary (CMB). Old subducted slabs and a thermal boundary layer lead to large-scale lateral structure near the CMB

Large and Small: Conserving Single Large and Several Small

Huxley College of the Environment’s field course on rainforest conservation traces some of its roots to a seminal 1967 publication. MacArthur and Wilson’s The Theory of Island Biogeography presented two fundamental principles. Larger islands support more species than smaller ones and remote islands support fewer species than less remote ones. Moreover, they also established how habitat can be insulated by not only distance between islands, but anything that divides a landscape such as mountains and climate. But the conservation implications of biogeography became dichotomized during the seventies and eighties into a debate between preserving a Single Large section of habitat, or Several Small and captured in the acronym SLOSS? Costa Rica’s preserved natural areas presented Western Washington University students with an excellent case study of this history of conservation biogeography and its future where protected area management embraces Single Large AND Several Small (SLASS). Moreover, Costa Rica offered a stimulating laboratory to explore the promise and pitfalls of SLASS for students from around the world and its implications for ecosystem conservation challenges everywhere (Boza, Jukofsky, and Willie, 1995)

Identity, Entitlement and Violence: A Cross Analysis of Intimate Partner Domestic Violent with the Palestinian-Israeli Conflict

This capstone investigates the root causes associated with domestic violence and compares such causes with those associated with the Palestinian-Israeli conflict to determine if the violence associated with both phenomena shares anything in common. Research regarding domestic violence was conducted at Washington County Department of Community Corrections (Oregon). Qualitative research included gathering the total number of domestic violence cases supervised by the county and calculating what percentages involved male and female perpetrators. Qualitative research included observations of and conversations with individuals under supervision for DV offenses and review of public archives. Research of the Palestinian-Israeli conflict included extensive reading of books and articles in order to obtain a diverse and comprehensive view of the conflict. Virtually all sources are autobiographical in nature or firsthand accounts of the conflict and include an array of perspectives (i.e. Palestinian, Arab, Muslim, Christian, Israeli, Jewish, American, female, academic, political, journalistic). Despite distinct differences, the research indicates that violence associated with domestic abuse shares an element in common with violence associated with the Palestinian-Israeli conflict: Some individuals or groups believe that based on their identities (i.e. Israeli, Jew, Palestinian, male) they are justified or entitled to use violence against ‘other’ identities (i.e. Palestinian, Israeli, Jew, female) under certain circumstances. This understanding provides a focal point where professional practitioners can offer challenges and alternatives to beliefs of entitlement and violence incorporated in identity when attempting to transform conflicts from violence, distrust and misunderstanding into peaceful, supportive relationships

Assessing Family Strengths Using the Family Profile: Study to Validate and Evaluate Constructs Across Four Models of Family Functioning

The concurrent criterion-related validity of the Family Profile (FAMPRO) was investigated using the Family Adaptability and Cohesion Scales II (FACES II), the Self-Report Family Inventory (SFI), and the Family Assessment Device (FAD) as criterion measures . Further analysis was conducted through a principal component factor analysis with a varimax rotation and correlations with a Family Satisfaction Scale. The Family Profile is an easy-to-administer, -score, and -interpret instrument designed for use in family life education. It is a 35-item instrument that measures seven areas of family functioning: Family Fun, Family Decisions, Family Pride, Family Values, Family Caring, Family Communication, and Family Confidence. The total scores of the Family Profile had strong correlations with the total scores of the three criterion instruments. Additionally, the individual constructs of the Family Profile showed moderate to strong relationships with the corresponding subscales found in the criterion instruments. Factor analysis of the FAMPRO with this sample indicated that the most important factor explaining the largest portion of the variance is the ability of family members to display positive regard to one another in an open and warm manner. The Family Satisfaction Scale created for this project was moderately to strongly correlated with all of the Family Profile\u27s Subscales. The sample used for this study was taken from undergraduate Family and Human Development classes at Utah State University and had a total N of 194. This nonrandom sample was mostly young, single, and female. The religious preference for 80% of the sample was Mormon (LDS). While the sample limits generalization of the results, these preliminary results provide sufficient evidence to warrant further research using the Family Profile. Because the FAMPRO is easy to use and interpret, it holds promise as an effective tool for family life educators and clinicians alike
