Father Dietz, the Catholic Church and the 1913 Michigan Copper Strike

Labor Historian Marc Karson has singled out “labor priest” Peter E. Dietz as one of the strongest proponents for the active implementation of the Catholic Church���s 1890’s labor encyclical Rerum Novarum in the daily practice of American Catholics. Biographer Sister Mary Harrita Fox pointed out that in his work, Dietz “was particularly concerned over the role of the church in the copper strike in Upper Michigan.” This “particular concern” should be noted since the 1913 strike was one of the only disputes where Dietz went out of his way to visit and become actively involved. Why the keen interest? This presentation will review the impetus for the huge effort which brought Peter E. Dietz to the Copper Country and solely to that dispute alone, the resulting visit and report that he made concerning the strike, the important role he believed this visit and stance in the Copper Strike had in the future of the Church���s relationship to the US labor movement. The presentation will look at both what Dietz thought would occur as a result of his 1913 trip to the Keweenaw and what actually happened in this pivotal pre-World War One era event. The paper will put Father Peter E. Dietz and the Catholic Church into the larger frame of how religion has been viewed within the history of the Strike.

Locating American Indian Sciences : a report on the development, use, and analysis of a survey of perceptions

All students in the United States of America are required to take science. But what if there is not a science, but in fact a number of sciences? Could every culture, perhaps every different grouping of people, create its own science? This report describes a preliminary survey, the goal of which is to improve the teaching of science at American Indian Opportunities and Industrialization Center in Minneapolis, Minnesota by beginning to understand the differences between Western and American Indian sciences.

Fish contaminants through the tribal perspective : an ethnography of the Keweenaw Bay Indian Community's tribal fish harvest

It has been well documented that many tribal populations and minority groups across the nation have been identified as being at high risk of the adverse health effects created by consuming fish that have been contaminated with mercury, PCBs, DDT, dioxins, and other chemicals. Although fish consumption advisories are intended to inform fish consumers of risks associated with specific species and water bodies, advisories have been the subject of both environmental injustices and treaty rights’ injustices. This means that understanding fish contaminants, through community perspectives is essential to good environmental policy. This study examined the fish contaminant knowledge, impacts on fishing and fish consumption, and the factors that contribute to harvesting decisions and behaviors in one tribal nation in the Upper Peninsula of Michigan, the Keweenaw Bay Indian Community. Using ethnographic methods, participant observation and semi-structured interviewing, fieldnotes were kept and all interviews were fully transcribed for data analysis. Among seventeen fishermen and women, contaminants are poorly understood, have had a limited impact on subsistence fishing but have had a substantial impact on commercial fishing activity. But ultimately, all decisions and behaviors are based on their own criteria and within a larger context of knowledge and understanding: the historical and cultural context. The historical context revealed that advisories are viewed as another attack on tribal fishing. The cultural context revealed that it is the fundamental guidance and essential framework associated with all harvesting beliefs, values, and traditional lifeways. These results have implications for advisories. ‘Fish’ and ‘contaminants’ appear differently based on the perceptions and priorities of those who encounter them.

STRUCTURAL CONTROL OF A SMALL-SCALE TEST-BED SHAKER STRUCTURE USING A SPONGE-TYPE MAGNETO-RHEOLOGICAL FLUID DAMPER

Semi-active damping devices have been shown to be effective in mitigating unwanted vibrations in civil structures. These devices impart force indirectly through real-time alterations to structural properties. Simulating the complex behavior of these devices for laboratory-scale experiments is a major challenge. Commercial devices for seismic applications typically operate in the 2-10 kN range; this force is too high for small-scale testing applications where requirements typically range from 0-10 N. Several challenges must be overcome to produce damping forces at this level. In this study, a small-scale magneto-rheological (MR) damper utilizing a fluid absorbent metal foam matrix is developed and tested to accomplish this goal. This matrix allows magneto-rheological (MR) fluid to be extracted upon magnetic excitation in order to produce MR-fluid shear stresses and viscosity effects between an electromagnetic piston, the foam, and the damper housing. Dampers for uniaxial seismic excitation are traditionally positioned in the horizontal orientation allowing MR-fluid to gather in the lower part of the damper housing when partially filled. Thus, the absorbent matrix is placed in the bottom of the housing relieving the need to fill the entire device with MR-fluid, a practice that requires seals that add significant unwanted friction to the desired low-force device. The damper, once constructed, can be used in feedback control applications to reduce seismic vibrations and to test structural control algorithms and wireless command devices. To validate this device, a parametric study was performed utilizing force and acceleration measurements to characterize damper performance and controllability for this actuator. A discussion of the results is presented to demonstrate the attainment of the damper design objectives.
