Wobblies in Washington: The Radicalism and Downfall of the IWW in the Northwest
This paper is an examination of the radical philosophy and propaganda of the Industrial Workers of The World (IWW), also known as the Wobblies, during the period of 1909-1919. in the Pacific Northwest, focusing on the State of Washington. In order to accomplish this, the paper examines several key Wobbly political cartoons, and explains the impact that their propaganda had on union organizing and labor movements in the Northwest. Additionally, The political atmosphere of the time period and the many clashes between the radical IWW and the mainstream American society of the time. Furthermore, this paper analyzes the way in which the radicalism of the IWW led to its downfall in Washington State, which was originally a Wobbly stronghold

Creating and testing the higher education leadership competencies (Helc) model: A study of athletics directors, senior student affairs officers, and chief academic officers
The purpose of this study was threefold: to extend existing knowledge of McDaniel\u27s (2002) qualitative inquiry of higher education leadership competencies by testing her theory using quantitative methods; to either affirm or create a new, more refined model of higher education leadership competencies based on the results of the data analysis; and finally, to compare the similarities and differences of important competencies necessary for effective leadership between and within three groups of leaders in higher education: athletics directors (ADs), senior student affairs officers (SSAOs), and chief academic officers (CAOs); Goodness of fit results indicated McDaniel\u27s 4-category model of higher education leadership competencies (context, content, process, and communication) was a marginal fit, at best (IFI = .730, CFI = .726, RMSEA = .070). Therefore, a new more refined model, called the Higher Education Leadership Competencies Model (HELC Model), was developed using factor analysis statistical procedures. Five categories emerged and were labeled by the researcher as analytical, communication, student affairs, behavioral, and external relations. Goodness of fit indices for the HELC Model (1171= .862, CFI = .860, RMSEA = .062) suggested a better fit than McDaniel\u27s model; Between and within group differences were also measured, based on the five categories of the HELC Model. For between group differences, SSAOs and CAOs ranked Analytical Leadership Competencies higher than ADs, however there was no difference between SSAOs and CAOs. SSAOs ranked Student Affairs Leadership Competencies higher than both ADs and CAOs, however, there was no difference between the level of importance between ADs and CAOs. Finally, ADs ranked External Relations Leadership Competencies higher than both SSAOs and CAOs, with no statistical difference between SSAOs and CAOs. There was no difference between groups for Communication Leadership Competencies, and Behavior Leadership Competencies; For within group differences, ADs ranked External Relations Leadership Competencies as most important for effective higher education leadership, SSAOs ranked Student Affairs Leadership Competencies as most important, and CAOs ranked Analytical, Communication, and Behavioral Leadership Competencies as most important; Responsibilities vary among athletics directors, senior student affairs officers, and chief academic officers within the greater context of higher education. As expected, groups ranked competencies associated with their own jobs higher in importance than competencies less relevant to their jobs
Home Equity Insurance & The Demise Of Home Value Insurance Corporation
This study uses the demise of the Home Value Insurance Company (HVIC) to explore whether the concept of home equity insurance is implementable. Shiller, R. and Weiss, A. (1999) and Goetzmann, W., Caplin, A., Hangen, E., Nalebuff, B., Prentce, E., Rodkin, J., Spiegel, M. and Skinner, T. (2003) have provided a platform to evaluate this concept by questioning whether a product that allows homeowners to transfer the risk associated with a decline in housing prices should be structured as insurance. This study explores the cost associated, in the U.S. Real Estate Market, with this risk transfer process in the pre and post mortgage crisis periods by simulating the cost of insurance using the theoretical pricing of ATM (at the money) put options based upon the Black Scholes Option Pricing Model from 1989 to 2013. As the U.S. Housing Market transitioned from the pre-crisis to the post-crisis periods the hypothetical breakeven cost of insurance increased from 0.60% to 20.85% of the starting value of the index. The demise of HVIC seems to be a cautionary tale: Given the recent changes in the underlying dynamics of the U.S. Real Estate Market it does not seem prudent (for insurers) to use insurance contracts to transfer the risk associated with a decline in the value of U.S. Residential Equity Wealth
Narrative structure and audience motivation in documentary film
Documentary film is meant to inform viewers on an issue and prompt them toward a change in behavior. In the environmental documentary, filmmakers charge audiences with affecting the world around them through an agency of greater understanding. The creators of the message must understand the most effective way to communicate the issue and how actions create change. Guided by narrative theory, which places the emphasis of effective communication on the ordered presentation of story elements, the researcher screened two environmental documentaries for 20 viewers and subjected them to a two-phase data collection via written questionnaires and focus group discussions to determine what elements viewers perceive to be the most impactful for presenting a crisis, motivating them to become involved in its resolution and the actions they were willing to take. The researcher found while viewers recognized narrative structure as one component for presenting this information, the identity of the creators and use of emotionally appealing human subjects were also influential for inspiring or preventing a desire to address environmental issues. The actions research subjects considered taking, when they felt so moved, were most strongly aligned with increasing their awareness of the issues and the environmental stances of local politicians
Reducing water extractable phosphorus in poultry litter using chitosan treatment
Phosphorus (P) is an important factor in the eutrophication of freshwater, and watershed sources include effluent discharges and the landscape. Poultry litter applied to the landscape can be a potential source of P, which is dependent on rainfall, runoff and dissolution. Chitosan, the deacetylated form of the biopolymer chitin, has been shown to have an effect on reducing water extractable phosphorus (WEP) in poultry litter when applied as a powder. The intent of this study was to measure the effect that poultry litter treatment (PLT), acetic acid and incubation time have on chitosan’s ability to reduce WEP in poultry litter. The results were that (1) the presence of PLT in the litter inhibits chitosan’s ability to reduce WEP; (2) chitosan dissolved in acetic acid (0.005, 0.01, 0.02, and 0.05 g mL-1) does not decrease WEP at any point during a 7 week incubation period; and (3) chitosan in a powder form reaches its full effectiveness after three weeks of incubation. Chitosan could be an effective coamendment to poultry litter with other treatments in order to reduce WEP
A Miniaturized Green End-Burning Hybrid Propulsion System for CubeSats
Conventional hybrid rocket motors with thrust levels greater than 5 N rely on forced convection within the boundary layer as the primary heat-transfer mechanism for fuel vaporization. For hybrid rockets with thrust levels less than 5 N, oxidizer mass flow levels are sufficiently small that the rate of convective heat transfer is significantly reduced, and radiative heat transfer dominates the fuel vaporization mechanism. Radiative heating is a potential concern when implementing traditional hybrid rocket core burn fuel grain designs for systems with low thrust levels adequate for small satellites and CubeSats. Radiative heating causes the system to be fuel rich leading to inefficient combustion and nozzle clogging. This paper presents a novel idea of using this radiative heating phenomenon in the design of a hybrid propulsion system suitable for CubeSats and small satellites. This paper presents the test results of two fuel grain designs, the first being an end burning design and the second a “sandwich” fuel grain design. ABS, PVC, Nylon-12 and acrylic known as PMMA were used as fuel and gaseous oxygen (GOX) was used as the oxidizer during this testing campaign. These propellants provide several advantages including: benign handling properties, simplified plumbing, and greater burn efficiency over traditional monopropellant hydrazine
The E2 ubiquitin-conjugating enzymes UBE2D1 and UBE2D2 regulate VEGFR2 dynamics and endothelial function
Vascular endothelial growth factor receptor 2 (VEGFR2, encoded by KDR) regulates endothelial function and angiogenesis. VEGFR2 undergoes ubiquitination that programs this receptor for trafficking and proteolysis, but the ubiquitin-modifying enzymes involved are ill-defined. Herein, we used a reverse genetics screen for the human E2 family of ubiquitin-conjugating enzymes to identify gene products that regulate VEGFR2 ubiquitination and proteolysis. We found that depletion of either UBE2D1 or UBE2D2 in endothelial cells caused a rise in steady-state VEGFR2 levels. This rise in plasma membrane VEGFR2 levels impacted on VEGF-A-stimulated signalling, with increased activation of canonical MAPK, phospholipase CÎł1 and Akt pathways. Analysis of biosynthetic VEGFR2 is consistent with a role for UBE2D enzymes in influencing plasma membrane VEGFR2 levels. Cell-surface-specific biotinylation and recycling studies showed an increase in VEGFR2 recycling to the plasma membrane upon reduction in UBE2D levels. Depletion of either UBE2D1 or UBE2D2 stimulated endothelial tubulogenesis, which is consistent with increased VEGFR2 plasma membrane levels promoting the cellular response to exogenous VEGF-A. Our studies identify a key role for UBE2D1 and UBE2D2 in regulating VEGFR2 function in angiogenesis
