Työmies and Pappi: A Critical Look at the Finnish Socialist Federation and the Suomi Synod in Early 20th Century Michigan

At the dawn of the 20th century, the burgeoning influence of the Finnish immigrant socialist-unionist movement collided with the authoritative, conservative nature of the Suomi Synod. While the Synod, headquartered in Hancock, Michigan, was attempting to recreate the Finnish state church in America, the quickly radicalizing immigrant socialist-unionist movement was attempting to convert the masses to a materialist message of class struggle manifested by then current conditions in Michigan’s Copper Country and industrial America. The most persuasive voice of class struggle for immigrant Finns at this time was the Finnish-language newspaper Työmies (The Workingman) published in Hancock. Caustic editorials on religion, critical examinations of Christian orthodoxy in translations of Marx and Kropotkin, and ribald cartoons lampooning members of the Synod clergy and laity all demonstrated the overwrought interactions between Työmies and the Synod. This paper will highlight these tense interactions through analysis of doctrine, ideology, and imagery by delving into the primary historical record to reveal the vast gulf between two of the major institutions in early 20th century Finnish immigrant social life.

DIFFUSE-INTERFACE FIELD APPROACH TO MODELING SELF-ASSEMBLY OF HETEROGENEOUS COLLOIDAL SYSTEMS AND RELATED DIPOLE-DIPOLE INTERACTION PHENOMENA

Colloid self-assembly under external control is a new route to fabrication of advanced materials with novel microstructures and appealing functionalities. The kinetic processes of colloidal self-assembly have attracted great interests also because they are similar to many atomic level kinetic processes of materials. In the past decades, rapid technological progresses have been achieved on producing shape-anisotropic, patchy, core-shell structured particles and particles with electric/magnetic charges/dipoles, which greatly enriched the self-assembled structures. Multi-phase carrier liquids offer new route to controlling colloidal self-assembly. Therefore, heterogeneity is the essential characteristics of colloid system, while so far there still lacks a model that is able to efficiently incorporate these possible heterogeneities. This thesis is mainly devoted to development of a model and computational study on the complex colloid system through a diffuse-interface field approach (DIFA), recently developed by Wang et al. This meso-scale model is able to describe arbitrary particle shape and arbitrary charge/dipole distribution on the surface or body of particles. Within the framework of DIFA, a Gibbs-Duhem-type formula is introduced to treat Laplace pressure in multi-liquid-phase colloidal system and it obeys Young-Laplace equation. The model is thus capable to quantitatively study important capillarity related phenomena. Extensive computer simulations are performed to study the fundamental behavior of heterogeneous colloidal system. The role of Laplace pressure is revealed in determining the mechanical equilibrium of shape-anisotropic particles at fluid interfaces. In particular, it is found that the Laplace pressure plays a critical role in maintaining the stability of capillary bridges between close particles, which sheds light on a novel route to in situ firming compact but fragile colloidal microstructures via capillary bridges. Simulation results also show that competition between like-charge repulsion, dipole-dipole interaction and Brownian motion dictates the degree of aggregation of heterogeneously charged particles. Assembly and alignment of particles with magnetic dipoles under external field is studied. Finally, extended studies on the role of dipole-dipole interaction are performed for ferromagnetic and ferroelectric domain phenomena. The results reveal that the internal field generated by dipoles competes with external field to determine the dipole-domain evolution in ferroic materials.
